The Real Time Clock Chip allows the date and time to be maintained in the local
printer rather than using the system clock. It consists of a special clock chip that
replaces the EEPROM chip on the main PCB.
STEP PROCEDURE
1. Switch the printer OFF and disconnect the power cable.
2. Remove (3) screws holding the left side cover to the printer. Raise the access
door and loosen the (2) screws on the inside top of the printer. Lift off the
left side cover to expose the main PCB. Fig. 9-26.
3. Refer to Figs. 9-27.
Remove the EEPROM chip. CAUTION: Using a screwdriver to remove
EEPROM may cause damage to the PCB. Be sure to have Prom
remover under EEPROM and not under the socket itself.
4. Install the Real Time Clock Chip in location vacated by the EEPROM chip.
Carefully align and insert the chip with the mark spot on the chip (identifying
pin1) securely into the chip block socket using the U shaped notch as refer-
ence. Be very careful not to bend any chip legs.
5. Replace the cover reversing removal steps.
6. Complete the Factory Reset Procedure.
