3. PRECAUTIONS WHEN SERVICING THE PRINTER

3.1 Stored Data

This printer counts the printing length, number of ink tank replacements, carriage
driving time, number of cleanings, and the cutter usage, and stores this information in
the system controller EEPROM (IC36) and in the engine controller EEPROM (IC421) as
the service mode counter.
The counter holds important information for indicating printer usage status.
You can check the printer information in the counter by printing it in service mode or
displaying it on the display.
Be sure to follow the precautions below when servicing the printer.
1) Repairing or replacing the PCB
Follow the "Each Controller Replacement Procedures" when replacing the system
controller and engine controller.

2) After replacing the carriage unit
The information on the carriage driving time is generated from the carriage unit.
Initialize (clear) the carriage driving time information after replacing the carriage unit.
3) After replacing the purge unit
The information on the number of cleanings is generated from the purge unit. Initialize
(clear) the number of cleanings information after replacing the purge unit.
CAUTION
For the "Each Controller Replacement Procedures," see
Boards.
You cannot check the counter information once it is initialized (cleared).
Be careful that you do not perform the initialization before checking the
information.
