It emulates GL/2 mode in the HP LaserJet 4 emulation. In EPSON GL/2 mode, however, the operator can reach some parameters with SelecType, without sending commands. ❏ GL-like mode: Used to print with software that supports the HP7475A series pen plotter. GL-like mode features all the commands for LJ4-GL/2 mode, except some instructions such as plotter unit and picture frame, that are the same as in EPSON GL/2 mode. However, since GL-like mode doesn’t support some commands used in the HP GL mode, print cannot be assured with application software that specifies those commands.

CG: CHASSIS -GND ❏ Signal descriptions StrobeX (in) Compatibility mode: Latch pulse used to read print data. DATA is valid when the signal is LOW. Negotiation phase: Latch pulse used to read an extensibility request value Nibble mode: Always HIGH ECP mode: Used to transmit print or address data from the host computer to the printer by handshaking with PeriphAck (Busy). DATA 1 to DATA 8 (in/out) All modes: DATA 8 is MSB and DATA 1 is LSB. Compatible mode Forward channel data Negotiation phase Extensibility request value Nibble mode Not used ECP mode Bidirectional data or address Acknlg (out) Compatible mode: An acknowledge pulse that indicates that data from the host computer has been received. [SE specification] This signal is always output along with the Busy signal. Strobe is independent of these signals. Negotiation phase: Indicates that IEEE 1284 is supported when it’s LOW, which later goes HIGH indicating that Xflag and Data Available Flag are valid. Reverse data transfer phase: Indicates that nibble data is valid when it’s LOW in nibble mode. Reverse idle phase: Switching this signal from LOW to HIGH causes an interruption informing the host computer that data is available. ECP mode Used to transmit data from the printer to the host computer by handshaking with HostAck (nAutfeed). Rev. A 1-19 Product Description EPL-N2000 Service Manual BUSY (out) Compatible mode: HIGH status indicates the printer is not ready to accept data. Negotiation phase: Reflects busy status in forward channel. Reverse data transfer phase: Nibble data bit is 3, then 7 in nibble mode. Reverse idle phase: Reflects busy status in forward channel. ECP mode: Used for flow control in forward channel. Also used in reverse mode as the 9th data bit, which indicates whether signal data information is data or command. PE (out) Compatible mode: Indicates paper jam or paper empty status in paper tray or cassette. ERRX goes LOW when PE goes HIGH. Negotiation phase: HIGH status indicates whether or not IEEE is supported. Then, it follows nDataAvail (nFault). Reverse data transfer phase: Nibble data bit is 2, then 6 in Nibble mode. Reverse idle phase: Remains HIGH until the host computer requests data transmission. Then, it follows nDataAvail (nFault). ECP mode: Aknowledges nReverseRequest when this signal is set to LOW. The host computer detects the status as an allowance to drive signal data. Slctout (out) Compatibility mode: Always HIGH Negotiation phase: Xflag indicates Extensibility flag. It is used in response to extensibility request value from the host computer. Reverse data transfer phase: Nibble data bit is 1, then 5 in nibble mode. Reverse idle phase: Same as negotiation phase. ECP mode: Same as negotiation phase. AutoX (in) Compatible mode: Not used. Negotiation phase: This signal goes HIGH and IEEE 1284 active (nSelectIN) goes LOW when requesting IEEE 1284 mode. Then it is set to HIGH by setting PtrClk (nAck) to LOW. Reverse data transfer phase: The host computer informs the printer that it is ready to receive data in nibble mode by setting this signal to LOW. Then sets the signal to HIGH to inform the printer that data has been received. Reverse idle phase: This signal goes HIGH in response to a LOW pulse of PtrClk (nAck) to enter reverse data phase again. Reverse idle phase is returned to compatibility mode if this signal goes HIGH and IEEE 1284 active (nselectIn) goes LOW at the same time. ECP mode: Used for flow control of forward channel. Also used in reverse mode as the 9th data bit, which indicates whether signal data information is valid data or command. 1-20 Rev. A EPL-N2000 Service Manual PeriLH (out) Product Description [SE specification] Only defined for IEEE 1284-C connector. Init (in) Compatible mode: As long as this signal is LOW, the Busy signal remains HIGH. 1. The printer processes data received before the signal goes LOW. 2. The printer ignores a LOW strobe pulse input while the signal is LOW. Negotiation phase: Always HIGH. Reverse data transfer phase: Always HIGH. ECP mode: Set to LOW when switching to reverse channel. Data signal can be transmitted to peripheral devices only when this signal is LOW and 1284 active is HIGH. Error (out) Compatible mode: Indicates an error has occurred when this signal is LOW.

When the DTR signal is HIGH, the printer can receive the RXD signal. When the SelecType settings do not specify DTR control, the signal level remains HIGH while printer power is on. When SelecType is used for DTR control, DTR goes LOW for any error condition. Data (RXD) from the host computer must be stopped within 128 characters after DTR goes LOW. CTS Always ignored. TXD Serial ASCII data output by the printer. It remains in MARK state (LOW level) between transmitted character codes. Logic 0 is at HIGH level (SPACE), and logic 1 is at LOW level (MARK). GND Connected to the printer chassis. The printer chassis GND and signal GND are connected to each other. RXD Serial ASCII data input to the printer. It maintains the MARK state (LOW level) between received character codes. 1-24 Rev. A EPL-N2000 Service Manual Product Description TTY-TXD Current loop signal: HIGH impedance (SPACE) between pins 17 and 24 or X-ON signal sent across pins 17 and 24 indicates that the printer is ready to accept data; LOW impedance (MARK) or X-OFF signal sent indicates that the printer is busy. TTY-RXD Return Current loop signal: Current return for pin 17. TTY-TXD Return Current loop signal: Input data current loop. TTY-RXD Current loop signal: Current return to pin 25. Protocol There are two types of protocols, as listed below, and each of them can be designated by the SelecType independently. ❒ DTR/DSR protocol The DTR/DSR control protocol can be selected by SelecType. The DTR signal is set to a HIGH level when the printer is ready to receive data, and to LOW when an error is detected. DTR remains HIGH when SelecType is set to OFF for DTR control. The printer sends only TXD off when the DSR signal is HIGH. (DSR signal is always assumed HIGH when select mode for DSR is set to OFF. X-ON/X-OFF transmission is independent of DSR. ❒ X-ON/X-OFF (DC1/DC3) protocol Select mode is used to execute X-ON/X-OFF protocol. The X-OFF (DC3) code, transmitted by error detection, warns the host computer to stop sending data within 128 characters. No further X-OFF codes are sent in response to additional data sent from the host computer after the warning has been given once. An X-ON code is transmitted when all the errors are cleared. The X-OFF code is transmitted only once when the remaining capacity of receiving buffer drops under for 128 characters, or any error occurs. The X-ON code is sent when the printer is powered on. The SelecType setting can be used to withhold X-ON/X-OFF code transmission. Rev.

Interface Auto Sense Mode 1-50 Rev. A EPL-N2000 Service Manual Product Description 1.4.6 Controller RAM Status RAM on the controller of this printer uses dynamic memory allocation to make the best use of the memory. Therefore, no portion is rigidly allocated for user-defined settings such as font download, form overlay, and buffer size, and the total amount of memory available changes depending on new values. When data exceeds memory capacity during a process, the error message Mem Overflow appears on the LCD. In this case, more memory needs to be added. You can occasionally prevent the error by decreasing memory buffer size. 1.4.7 EJL (Epson Job Control Language) This printer supports EPSON’s original EJL. This system allows users to access printer setting modes through commands sent by the computer. This mode is especially beneficial to users who operate printers through the network. 1.4.8 BiRITech (Bi Resolution Improvement Technology) This printer has BiRITech, which is used to smooth out jagged edges of lines or shapes. The resolution, with this technology, has been improved to control dot formation in the main scan at approximately 1200 dpi, and it provides printing of a high quality. Note: Using BiRITech may possibly cause print quality to deteriorate with meshed patterns or special graphic images. You can avoid this by setting BiRITech to OFF in SelecType. 1 inch 1 2 3 4 600 1 2 3 4 1 inch 5 6 7 R 8 600 Figure 1-8. BiRITech Function Rev. A 1-51 Product Description EPL-N2000 Service Manual 1.4.9 PGI (Photo and Graphics Improvement ) PGI enhances the print quality of halftones and tone gradations, generally used in photographic and graphic images. Compared with conventional systems, which use one white or black dot as the minimum unit, PGI technology divides a single dot into 3 parts for a more precise image. Therefore, the amount of data required for this technology is twice as large as the previous method. 1.4.10 Toner Saver Mode Toner saver mode can cut toner consumption to half normal use. The printer saves toner by substituting a gray shade, formed with reduced dots, for the black inside characters. The upper and right edges are reinforced with full black lines. Use of this mode, however, is limited to output that does not require good print quality. Table 1-25. Toner Saver Mode Toner Saver Mode Off On *1: Edge Reinforcement All edges Halftone/ Full Black Full black 1 Upper and right edge* Halftone made of 2 dots out of 4 X 4 dots. Toward the orientation in which image is laid, regardless of the direction paper is fed. Reinforced Halftone Normal Mode Toner save mode Figure 1-9. Toner Save Mode 1.4.11 Precaution for Power Off This printer has an EEPROM installed on the main controller to store user default settings . If the printer is turned off while the printer is writing new data to the EEPROM, that new data will be lost, and this may cause an error the next time the printer is powered on. To avoid this, do not turn off the printer until the message Ready is indicated on the LCD. 1-52 Rev.

Table 2-1. Printing Process for the EPL-N2000 Steps Process Description 1 Charging Charges the surface of the PC drum with static electricity. A rayon brush is used. 2 Exposure The laser beam emitted from the laser unit produces an electrostatic latent image on the surface of the PC drum. 3 Development Toner is fed through the sleeve roller to the surface of the PC drum to produce a visible toner image. Transfer The transfer roller transfers the toner image from the surface of the PC drum onto the paper, using an electrical charge applied from the transfer roller. 5 Separating The electrode discharges the paper to separate it from the drum. 6 Fusing Toner image is fixed on the paper with heat and pressure. 7 Cleaning The cleaning blade clears toner off the PC drum and transfer roller. 4 Figure 2-1 shows the locations and name of the main engine components and the paper paths.

Mechanism Parts and Paper Paths for Main Printing Process Rev.A 2-1 Operating Principles EPL-N2000 Service Manual 2.1.1.1 Charging Process In the charging process, the high voltage unit applies negative DC voltage as the bias voltage to the rayon charging brush. Then, the PC drum is evenly charged with the negative electric charge applied from the charging brush. DC bias Charging Brush –1150 V Charge Bias:-1150V (DC) PC Drum PC Drum Ground Figure 2-2. Charging Process 2-2 Rev.A EPL-N2000 Service Manual Operating Principles 2.1.1.2 Exposure Process In the exposure process, the laser unit emits laser beams onto the PC drum surface to create an electrostatic latent image. There is a polygon mirror installed inside the laser unit. The mirror, which is rotated by the scanner motor, reflects laser beams from the laser diode toward the drum, on which the laser beams run, scanning from one edge to the other. There is a sensor called SOS, or Start Of Scan, sensor attached in the laser unit. The laser beam is emitted onto the sensor to detect the starting point for scanning of each line. It correctly times the illumination of the laser diode with the rotation of the polygon mirror.

Exposure Process Rev.A 2-3 Operating Principles EPL-N2000 Service Manual 2.1.1.3 Developing Process Paper goes through this process to convert electrostatic image produced through the charging and exposure processes into visible image. It is accomplished using toner and 3 bias voltages; developingt bias, toner bias, and seal bias. Developing bias feeds toner evenly on the sleeve roller. The amount of toner fed onto the roller is controlled by developing bias, which enables the printer to adjust printing tones. Developing bias –300 V (–220 to –330 V) Toner bias –550 V Seal bias –249 bias Developing bias:-300V (-220V to -330V ) Toner bias:-500V PC Drum PWB-F High Voltage Unit Sleeve Roller Toner Hopper Seal bias:-249V Toner Feed Roller Figure 2-4. Developing Process 2-4 Rev.A EPL-N2000 Service Manual Operating Principles 2.1.1.4 Transfer Process In the transfer system, toner image created on the PC drum through the developing process is transferred to the paper. The roller transfer system is used for this printer. When the paper goes through the PC drum and the transfer roller, the roller provides the paper with positive voltage applied from the high voltage unit. Then, the toner image on the drum transfers to the paper being attracted by the positive voltage. The needle pole located above the roller is used to collect the remaining static electricity on the paper.

Transfer Process Rev.A 2-5 Operating Principles EPL-N2000 Service Manual 2.1.1.5 Fusing Process The fusing unit permanently fixes the toner image, transferred from the PC drum, onto the paper. The fusing system this printer uses is the heat roller fusing system. The toner on the paper is melted by the upper fusing roller, which is heated by the heater lamp, then the toner is fixed by pressure from the paper traveling through the upper and lower fusing rollers. There is a thermostat and thermistor installed on the upper fusing roller.The thermistor detects the surface temperature of the upper fusing roller. The PWB-A board switches the heater lamp on or off, depending on the temperature detected. When the temperature is abnormally high, which is usually caused by a malfunction of the control board or the thermistor, the thermostat detects it and cuts off the current. During warm up, the heater continues to heat up until it reaches 190oC (374 F). At printing, the heater is controlled to remain 180oC (356 F).

Fusing Process 2-6 Rev.A EPL-N2000 Service Manual Operating Principles 2.1.1.6 Cleaning Process Toner remaining on the PC drum after transfer process is scraped off with the cleaning blade, placed in close contact with the surface of the PC drum. The toner that has been scraped off is collected back into the toner collection box inside the Imaging cartridge. 2.1.2 Engine Mechanism Operation This section describes the major units in the engine and their mechanisms. 2.1.2.1 Fusing Unit ❏ Upper fusing roller A metallic sleeve roller that melts the toner on the paper. It is heated by a heater lamp built internally. ❏ Lower fusing roller A silicon rubber roller that applies pressure to the paper for fusing the toner to the page. ❏ Heater lamp A lamp built into the upper fusing roller. This is supplied AC power to heat the upper fusing roller. ❏ Thermistor The thermistor, located next to the upper fusing roller, detects the roller’s surface temperature. To control the roller’s temperature, the control circuit alternately switches the heater lamp on and off based on the temperature the thermistor detects. (This process continues occurring as long as the thermostat does not detect overheating.) ❏ Thermostat When the thermistor fails to control the temperature, the thermostat takes over the job. The thermostat has a series connection to the heater lamp’s power source line, and when the temperature rises to the specific level, it opens the contact point. Then current is cut off as a consequence. Rev.A 2-7 Operating Principles EPL-N2000 Service Manual 2.1.2.2 Paper Feeding Mechanism ❏ Multi Purpose Tray The drive for the tray is transmitted to the push-down cam by way of the main motor, paper takeup clutch, and paper takeup roller. The paper takeup roller and push-down cam rotate once when the the paper takeup solenoid is energized. While turning, the push-down cam pushes down the stack of paper on the paper lifting plate. Then the paper takeup roller picks up a sheet of paper. Friction between the paper separator and transport roller avoid multiple paper feeding. Push-down Cam Transport Roller Paper Takeup Roller Paper Takeup Clutch Separator Paper Lifting Plate Paper Take-up Solenoid Figure 2-7. Paper Tray Feed Mechanism 2-8 Rev.A EPL-N2000 Service Manual ❏ Operating Principles Lower Cassette Tray The drive for the lower cassette tray is transmitted from the printer to the transport roller via the transmission gear, paper takeup clutch, and paper takeup roller. The lower paper cassette unit is controlled by the engine control board (PWB-A) through control board PWB-C. When the paper takeup solenoid (SL2) is energized, the paper takeup roller rotates once to pick up a sheet of paper, and the transport roller carries it to the PC drum. The separator avoides multiple paper feeding. The paper size switch on control board (PWB-C) detects the size of the paper loaded in the tray. The paper near-empty sensor detects 2 conditions: whether the amount of paper remaining in the tray is 50 sheets or less or whether it is 250 sheets or less. The paper empty sensor is used to detect paper empty condition. Table 2-2 shows combinations of the paper sizes and corresponding switches. Table 2-2.

If the buffer size (which varies depending on the SelecType setting) is increased, the host computer is released sooner. Data and commands are then stored in the video RAM (the image buffer) memory area after being processed in the video controller CPU, where the data is converted into print bitmap data (image data). The size of the video RAM depends on the current size of the RAM memory and the SelecType setting. An error or warning for memory size occurs under the following conditions, and such problems usually can be solved by changing buffer size or increasing RAM memory: ❏ Bitmap data from the CPU is too complicated for the size of video RAM. ❏ When data is complicated, the CPU cannot process it faster than it is transmitted to the engine controller board. Image data stored in video RAM is transmitted to the ASIC, where the BiRITech and PGI functions manipulate the data. The data is then passed on to the engine controller as video data. The engine controller processes the video data transmitted from the video controller. Engine mechanisms driven by the PWB-A board then perform printing. When an error occurs, the CPU in the engine controller detects it and sends status information to the video controller, where the information is processed, and the corresponding error message and the code are displayed on the Control panel.

WARNING ❏ Disconnect the power cord before disassembling/assembling the printer. ❏ Be sure to handle the fusing unit carefully, because the unit remains hot for a while after the printer stops printing. ❏ If it is necessary to plug in the power cord and operate the printer after disassembling it, take the following precautions: 1.Keep your hands and clothing well away from operating or rotating parts (such as rollers, fan motors, etc.) 2.Never touch electric terminals or high-voltage components (such as the charger and the high voltage unit). ❏ Be sure to close the top cover when operating the printer. This printer uses an invisible laser beam which could cause damage or loss of eyesight. Therefore never energize the interlock switch to connect current with the top cover open. CAUTION ❏ Handle frame edges with care since this printer has a considerable amount of metal materials. ❏ Do not disassemble the Imaging cartridge. ❏ If the Imaging cartridge is removed from the printer, do not place it in direct sunlight. ❏ Do not disassemble the printhead assembly. ❏ To prevent damage to ICs from static electricity, do not touch the ICs on the circuit board or the terminals of peripheral electrical components with your hands. ❏ Use only the recommended tools to ensure safe and efficient maintenance work. Inappropriate tools may damage the machine. ❏ Never open the top cover until the main motor stops completely. ❏ When transporting the printer, remove the Imaging cartridge. ❏ When transporting the printer a long distance, pack it using the original packing material. 3.1.2 Tools Use the tools listed in Table 3-1 for disassembling/assembling the printer.

A Checkpoint Check 3-3 Disassembly and Assembly EPL-N2000 Service Manual 3.1.5 Servicing Operations This section describes the special service modes and combinations of switches used to enter each mode. The modes listed in this section are only to be operated by qualified service people for repair. Therefore the specifications for these modes were eliminated from the user’s guide. ❏ EEPROM Initialization The EEPROM, mounted on the controller board, is used to save settings selected through the SelecType mode and the printer status information such as the page counter. This function resets all user settings and printer status information to the factory default settings. ■ Switches to use: Turn on the printer while holding down the On Line, Continue, and Menu switches. CAUTION Use of this function must be limited to the the conditions listed below, since it also clears page counter information. ❏ EEPROM is replaced. ❏ The C207 MAIN Board, along with EEPROM, is replaced. ❏ When refurbishing the EEPROM. ❏ Page Counter Clearance The page counter information, which can be checked through the SelecType, is stored on the EEPROM. The page counter clear function resets the page counter to "0". ■ Switches to use: Turn on the printer while holding down the On Line, Item, and Menu switches. ❏ Flash IC Card Clear When the optional flash IC card is used, the saved information in the card is erased with this mode. It’s only available when the card is inserted in card slot A. ■ Switches to use: Turn on the printer while holding down the SelecType, Item, Value, and Enter switches. "Formatting Card" appears, which is indicated on the LCD. "Write Error Card" is indicated in place of "Formatting Card" under the following conditions. The IC card inserted is not acceptable. The card is write protected. ❏ Flash ROM Update This function is used to update a Flash ROM. ■ Switches to use: 1. Turn On the printer while holding down the On Line, Menu, Item, and Value switches. 2. Press the Item, Value, and Enter switches while "Program Device" is indicated. The parallel interface (B connector) starts sending data when "Please Send Data" is indicated. 3-4 Rev. A EPL-N2000 Service Manual Disassembly and Assembly Use the 2 other modes listed below when you need information to analyzing the cause of a persistent error related to a firmware malfunction. ❏ Resetting of the CPU after a service call error has occurred. When a "Exxx" or "C2000" error has occurred, it can be cleared using this function without turning the printer Off and back On. ■ Switches to use: Press the SelecType, Menu, Item, Value, and Enter switches. This combination is effective only when the printer is in an error status. ❏ Indication of service call error details When a "Exxx" or "C2000" error has occurred, detailed information on the error can be indicated by using this function. ■ Switches to use: Press the Continue, SelecType, and Menu switches at one time. The LCD panel displays detailed information on the error. If any of the switches is then pressed, error type is displayed. Rev.

Appropriate maintenance after troubleshooting, as well as after the occasional replacement of worn out units, is essential to prevent potential problems from occurring. Maintenance items described in this section are divided into two subsections: user maintenance and service maintenance (performed only by qualified repair personnel). 6.1.1 User Maintenance Users can achieve maximum print quality from the printer by following the instructions in Table 6-1. Table 6-1. Instructions for User Maintenance Item Occasion Procedure Clean the printhead unit glass Abnormal symptom such as vertical lines appear. Clean the glass surface with a dry, soft cloth. Imaging cartridge replacement Print quality has deteriorated or Replace the Imaging cartridge. the total number of printed pages exceeds the specified maximum (Approximately 8,000 to 10,000 sheets). 6.1.2 Service Maintenance The EPSON EPL-N2000 does not require any replacement of units at specified intervals. It is, however, recommended that specific units be replaced after periods determined by the total number of sheets printed. This is indispensable in preventing abnormal operations, such as multi-sheet feeds, paper jams, and fusing malfunctions, which can be often caused by worn out units. Refer to Table 6-2 for guidance. Table 6-2. Instructions for Service Maintenance Unit Printable number of sheets The fusing unit Approximately 60,000 to120,000 sheets The paper takeup roller assembly Approximately 120,000 sheets The transfer unit Approximately 60,000 to 120,000 sheets ❏ If dirt sticks, use a moist cloth, and then clean with a dry cloth. ❏ Do not use solvents, such as thinner and alcohol. ❏ Never touch the surface of the transfer roller. When it needs cleaning, run blank prints repeatedly. Otherwise, remove the transfer unit and blow off the dust using an air gun. Rev.
