LASER SAFETY
This LBP printer is certified as a Class 1 laser product under the U.S. Department of Health
and Human Services (DHHS) Radiation Performance Standard according to the Food, Drug
and Cosmetic Act of 1990. This means that the LBP printer does not produce hazardous laser
radiation.
Since radiation emitted inside the LBP printer is completely confined within protective
housing and external covers, the laser beam cannot escape from the LBP printer during
any phase of user operation.
CDRH REGULATIONS
The Center for Devices and R&ological Health (CDRH) of the U.S. Food and Drug
Administration implemented regulations for laser products on August 2, 1976. These
regulations apply to laser products manufactured from August 1, 1976. Compliance is
mandatory for products marketed in the United States. The label shown in the figure
indicates compliance with the CDRH regulations and must be attached to laser products
marketed in the United States-.

HANDLING THE P.W.B.
Observe the folIowing precautions when handling a P.W.B. with ICs.
(1) During Transportation/ Storage
i:
1. During transport and storage, P.WB.s should be kept incarductive bags or on mats and not taken
out lmkss absolutely rEce.ssary.
2. P.WBs should be stored in a place where direct sunlight does not strike them.
3.Don0ttouch1Ctermin&withyourhands.
(2) At Replacement
1. Before removing connectors from a P.WB.. make sure the printer has been ~npluggcd
2. When P.WB.s are taken out of their conductive bags or off their mats, hold them by t&sir edges to
avoid touching the term&Is or the patterned surfaces.
3.BeforeinstallingumnectcrsonaP.WB..makesuretheprinterhasbeenunplugged.
(3) At Inspection
1. Avoid checking a P.WB. with testers; instead, use operating pa.tQ of the printer. mdicatrx ktrps,
and other means to evaluate operational umditions.
2. Be careful not to short-circuit IC terminals when using metal instruments or screws.

- When the paper take-up solenoid (SLl) is eneqixd. the paper take-up roll and push-down cam turn one
complete turn. As the push-down cam turns. the paper lifting plate is raised so that the paper tak-up roll can
t& up one sheet of paper. The friction with the separator pad ensures thatonlyoaesheetcxfpaperistaktn

9-2. Duplex (Option)
- When the duplex unit is mounted on the printer, t&e exit roller is co-ted to the switchback motor (MC) by
way of the coupling lever and gear.
1. When the printing cycle is completed for l-sided printing, the paper, moving past the exit sensor, is fed out of
the printer by the exit roller.
2. When the printing cycle is completed for the front side in 24ded printing, the paper is fed towards the exit by
the exit roller until it moves past the exit sensor. When the paper move3 past the exit sensor, the switchback
motor (M6) is turned backward feeding the paper back to the duplex paper take-up area The transport motor
(M5) then transports the paper up to the registration roller. Skew in paper is corrected by the registration senscx
ad then the registration roller feeds the paper to the image transfer section far printing to the back side. The
paper, having gone through the second print cycle, is fed out of the printer by the exit rokr.

1. JAM DETECTION
Note: This printer detects the following misfeeds and malfunctions. When any of these trouble
conditions is detected, all printer elements are brought to a stop except the fan motor.
l-l. JAM Detection
A misfeed may be cla&ied into one of four categories, JAMl. JAM2. JAM3, and JAM4, as detailed below.
1. When paper is fed from the Multi-purpose tray, the Paper Take-up Sensor (PCl) is in the deactivated state
approx. 1.6 sec. after the Paper Take-up Roll has started turning (JAN).
2. When paper is fed from the 2nd paper tray, the Registration Sensa (PCRl) is in the deactivated state
approx. 1.4 sec. (approx. 2.5 sec. for the Third Cassette Unit) after the Paper Take-up Roll has started
turning (JAhll).
3. when paper is fed from the 2nd paper tray. the Paper Take-up Sensor @Cl) is in tk deactivated state
approx. 1.0 sec. after the leading edge of the paper has reached the,&gistration Sensor @‘CXi) (JAMl).

1-2. Fusing Unit malfunction
l%e printer considers that there is a fusing malfunction when any of the following four conditions is detected.
1. The temperahue of the upper fusing roller (as measured withtbethermistor)issuchthatthechangein
the thermistor voltage is O.lV or less over a period between 12 sec. to 30 sec. after warm-up has star&xi
(with the fusing rollff temperature being 16OT or less).
2. The fusing roller temperature does not exceed l!WC for a 120 sec. pericd after warm-up has started.
3. The fusing roller temperature becanes less than 14UT in t.be standby state.
4. ‘Ihe fusing roller temperature become less than 1WC during a printing cycle.
5. The fusing roller temperature remains more than 24OT while the fusing temperature is being controlled.
13. Laser malfunction
T%e laser output level is adjusted befoxe printing.
A laser fault is detected if the output level cannot be adjusted to the specSed value.

2. A power supply fan motor malfunction is detected when the voltage used to detect the power supply fan
motorcurrentremains 170/150 mV or less (= high speed/low speed) for a cc&mous 0.43 sec. period.
l-6. Main Motor malfunction
The printer considers that there is a main drive motor malfunction when any of the following two conditions is
detected.
1. The main drive motor lock signal (co~tor CNSA-1) remains OFF for a continuous 1.0 sec. period.,
2.Themaindrivemotilccksignal(connec tor CN5A-1) is OFF 1.0 sec. after the Main drive motor has

7. All information contained in this parts manual is subject to change.
6. All parts numbers consist of ‘ten-digils’ which should all be quoted when ordering a part.
The price of parts can be obtained by referring to Ihe “Parts Price List’ which is separately
issued.
5. In the exploded views in this parts manual parts (Screws 81 Washes, etc...) which are
indicated with a “four-digit’ numbers are listed in numerical order in the section ‘SCREWS
AND WASHERS. Please check these ‘four-digil’ numbers with Ihe part numbers (‘lendigit” number) which should be used lor ordering the parts.
4. The Area Number is listed in the Area Column for only those parts used in certain market
areas. This Area Number represents the area listed opposite to it in the Chart given on
Page If. Parts having no Area Number lisled in the Area Column can be used in all
market areas.
3. The Index Number on the List Page is composed of two numbers and two letters.
Generally, only A is used as the first letter of the two letters. However, sometimes B, C, 0.
etc.are used when one part in the illustration, such as an electrical part or a part which
varies according to market ares, has two or more part numbers. The second of the IWO
letters represents the modification hislory of that part.
2. Parts whose numbers are preceded by an asterisk in the Index Column on the List Page
are parts to be used in only certain market areas. Therefore, please check the number in
the Area column on the List Page and then compare it with the numbers given in the Area
Chart on page If to find out which part number is applicable to your own area.
NOTE: Parts for only certain Market Areas: The part numbers for these parts vary
according to market area. In other cases, these parts are used in only restricled
