This printer counts the print length, number of ink tank replacements, carriage driving time, number of cleaning operations, number of cutter operations, and so on

and stores them in the main controller's EEPROM as a service mode counter.

This counter provides important information about the printer usage status.

You can check this information by printing it in the service mode or displaying it on the display.

Following the precautions below when servicing the printer.

(1) Repairing/replacing the PCB

When replacing the main controller, follow the specified replacement procedure.

Reference:

For the main controller replacement procedure, see Disassembly/Reassembly > Points to Note on Disassembly and Reassembly > Boards.

(2) After replacing the carriage unit

The information about the carriage driving time arises in the carriage unit. After replacing the carriage unit, select INITIALIZE > CARRIAGE in the service mode

to initialize (clear) the information about the carriage driving time.

(3) After replacing the purge unit

The information about the number of cleanings arises in the purge unit. After replacing the purge unit, select INITIALIZE > PURGE in the service mode to initialize

(clear) the information about the number of cleanings.

You cannot check the counter information once it is initialized (cleared). Be careful not to initialize the counter information before checking it.

You cannot modify the counter information from the operation panel.

1.7.3.2 Confirming the Firmware Version

electrical characteristics.

Before disassembling the printer for servicing, discharge any static buildup by touching a grounded metal fitting or the like.
