PRINTER Departments/PLU Code: The department code or PLU code entered appears on the left. For example, if the key for department 1 is pressed, "1" would appear in the extreme left position. Repeat: Indicates the number of times the same department key is pressed. If an entry is repeated more than ten times, only the first digit is displayed (12 displays as "2"). (E) Error: This symbol appears, accompanied by a warning beep, when an error is made. If this occurs during a transaction because of an excessive digit entry, simply press CL and re-enter correctly. (P) Program: This symbol remains on the display when the cash register is being programmed in the Z/PGM mode. (F) Finalization: This symbol appears when a transaction is finalized by pressing CA/AT/NS , CH or CHK . (o) Subtotal: This symbol appears when #/SBTL is pressed and the cash register computes the subtotal, and also when the amount tendered is less than the total sale amount. (C) Change: This symbol appears whenever the change due amount is displayed. (L) Low battery: This symbol appears when the power of the installed batteries is below a certain level or you need to replace the batteries with new ones. (see the "Maintenance" section for explanation.) (L) No battery: This symbol appears when no batteries are installed. (see "Maintenance" and "Getting Started" sections for explanation.) In addition, the following appear when appropriate: • The minus sign (-) can appear in positions 2 to 8. • The decimal point appears in positions 1 to 3. • When entry of the secret code is necessary, "---"appears in positions 1 to 4. 1) PRINTER • Model name: M-31 • No. of stations: 1 • Printing system: Print wheel selective type • Printing capacity: max. 13 characters • Character size: 1.6mm (W) x 2.8mm (H) • Print pitch: Column distance 2.1mm (numeric to numeric), 2.6mm (numeric to symbol) Row distance 4.6mm • Print speed: Approximate 1.4 lines/s (6 digits/line) • Paper feed speed: Approximate 4.3 lines/s • Reliability: MCBF 0.3 million lines 2) PAPER • Paper roll dimension: 57.5 0.5mm max. 80mm in diameter • Paper quality: Bond paper (paper thickness: 0.06 to 0.085mm paper weight: 47 to 64g/m2) 3) INKING • Ink supply system: Ink rill • From: Roller • Specification: Material - rubber • Ribbon life: 0.7 million characters • Print color: purple 4) LOGO STAMP (No) 5) CUTTER • Manual cutter 6) PRINTING WHEEL LAYOUT 1 2 3 4 5 6 7 8 9 10 11 12 13 0 0 0 0 0 0 0 0 0 0 0 0 0 X 1 1 1 1 1 1 1 1 1 1 1 1 1 Z 2 2 2 2 2 2 2 2 2 2 2 2 2 RA 3 3 3 3 3 3 3 3 3 3 3 3 3 PO 4 4 4 4 4 4 4 4 4 4 4 4 4 VD 5 5 5 5 5 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 6 6 6 6 6 @ 7 7 7 7 7 7 7 7 7 7 7 7 7 ST 8 8 8 8 8 8 8 8 8 8 8 8 8 TX 9 9 9 9 9 9 9 9 9 9 9 9 9 CA % 10 11 CH 12 13 # CK # # # # # # # # # # # CG 2) LOW BATTERY 7. DRAWER Low battery indication will appear on the left side of display when the battery voltage is low. [OUTLINE] Yes (1) • Standard equipment: • Max. number of drawers: 1 • The drawer consists of: CASE 1: When sitting idle or after completion of transaction. The machine can indicate the low battery condition (Always) CASE 2: Low battery indication will not appear during key operations, but will appear after power up of the cash register. (1) Drawer box (outer case) and drawer (2) Money case (3) Coin case (4) Lock (attached to the drawer) [Display sample] " 0.00" : Battery is OK. "L 0.00" : Low battery (You have to change the batteries.) [SPECIFICATION] After finalization "F 12.34" : Battery is OK. "L 12.34" : Low battery ("L" indicate instead of "F".) 1) DRAWER BOX AND DRAWER Size Material Bell Release lever Drawer open sensor 330 (W) x 363 (D) x 98 (H) mm 13 (W) x 14.3 (D) x 3.9 (H) inches Plastic – Standard equipment: situated at the bottom – 2) MONEY CASE Separation from the drawer Separation of the bill compartments from the coin compartments Bill separator Number of compartments Disallowed Allowed – 4B/5C Layout: 3) NO BATTERY If the user forgets to replace the battery and the battery voltage falls below a certain level, or if a power failure occurs with no batteries installed, the memory contents cannot be retained. The CPU judges it as no battery and performs the master reset. In this case, all the settings and registrations are cleared. If, however, the power is continuously supplied to the AC cord, the memory contents are retained. Low battery : Batteries are installed, but the voltage is low. Memory back up can be done. No battery : Batteries are not installed or the voltage is extremely low. The master reset is executed when a power failure occurs, when the batteries are not properly charged. Low battery & No battery indication will appear at the most left position of display when the battery voltage is low. CASE 1: When any numeric entry & item entry is not done or just after finalization. The machine can indicate the battery condition. (Always) 4B/5C 3) LOCK (LOCK KEY : LKGIM7331BHZZ) • Location of the lock: Front • Method of locking and unlocking: • Key No: To lock, insert the drawer lock key into the lock and turn it 90 degrees counter clockwise. To unlock, insert the drawer lock key and turn it 90 degrees clockwise. SK1-1 8. BATTERY 1) MEMORY BACK UP BATTERY For memory back up, the dry battery ULM-3 (3 pieces) are needed. 1. Memory holding time: Approx. 1 year after New dry batteries are installed. 2. Battery exchange method: When the low battery symbol "L" lights up, replace the batteries (3 AA) replaced by the following method; 1) Power on the ECR. 2) Mode switch turn to "REG" mode. 3) Remove the OLD dry batteries (3 pieces). 4) Insert the NEW dry batteries (3 pieces). 5) Confirm the low battery symbol "L" is off. CASE 2: When numeric entry or item entry is done. Battery condition is not appeared. Exceptionally, at the power is restored after power failure, the low battery & No battery indication will appear on the display only when the battery voltage is low. And the indication will disappear after any key entry. [Display sample] " 0.00" : Battery is OK. "L 0.00" : Low battery "L 0.00" : No battery After finalization "F 12.34" : Battery is OK. "L 12.34" : Low battery ("L" indicate instead of "F".) "L 12.34" : No battery ("L" indicate instead of "F".) L L CHAPTER 2. OPTIONS 1. OPTIONS (No) 2. SERVICE OPTIONS (No) 3. SUPPLIES NO NAME PARTS CODE PRICE RANK 1 ROLL PAPER AS 2 INK ROLLER AF 4 SPECIAL SERVICE TOOLS (No) CHAPTER 3. MASTER RESET Master reset: Clears all the memory and initializes each preset parameter. The master reset should be performed by using the following procedure. 1. Turn off the power (Power OFF). (See Note 1.) 2. Let the ECR be without the memory back up battery. 3. Turn the mode switch to the others of Power-off position. 4. Turn on the power (Power ON). (See Note 2.) When the master rest is completed, the buzzer sounds intermittently three times. 5. Attach the memory back up battery to the ECR. The master reset can also be accomplished in the following case. (See Note 3.) Note 1) Power OFF: Means disconnecting the AC power supply to the machine. (Specifically, unplugging the machine.) Note 2) Power ON: Means connecting the AC power to the machine. (Specifically, plugging in the machine.) Note 3) In case a power failure occurs when the machine has no battery installed, the master reset operation is automatically performed after the power has been restored.
