d. Handling maintenance cartridges
Be careful in unloading a maintenance cartridge from the printer not to keep the used ink from spilling over.
e. Refilling the printer with inks
If the printer has been purged of inks through an automatic or manual ink drain for disassembly/reassembly
or for reshipping, refill the printer with inks as soon as possible after the completion of the work.
If residual inks in the printer dry, they could seize mechanical components, with the result of malfunctioning.
1.7.3 Precautions When Servicing Printer
1.7.3.1 Notes on the Data Stored in the Printer
0013-5152
This printer counts the print length, number of ink tank replacements, 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.
For the main controller replacement procedure, see "Disassembly/Reassembly" > "Points to Note on
Disassembly and Reassembly" > "Boards".
(2) 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.
(3) On replacement of supplies
After supplies have been replaced, execute [INITIALIZE] > [PARTS COUNTER] > [PARTS xx] in service
mode to initialize (clear) the parts counter information.
For the consumable parts, see "Maintenance" > "Consumable Parts".
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.
