1.7.3 Precautions When Servicing Printer

1.7.3.1 Tips on data stored in the printer

This printer memorizes the print length, how many times tanks have been replaced, how long the carriage has
been driven, how many times the printhead has been cleaned, how many times the cutter has been actuated and
so forth, and stores such statistics in service mode counters in EEPROM on the main controller.
The counters provide valuable information to help determine the status of printer utilization.
The counters may be printed out in service mode or displayed for visual verification.
Take notice of these instructions when servicing the printer:
a. Repairing/replacing the PCB
Follow a defined replacement routine to replace the main controller.
b. After replacement of the carriage unit
The carriage drive duration is a piece of information derived from the carriage unit. When the carriage unit
has been replaced, run INITIALIZE > CARRIAGE in service mode to initialize (clear) the carriage drive
duration information.
c. After replacement of the purge unit
The cleaning count is a piece of information derived from the purge unit. When the purge unit has been
replaced, run INITIALIZE > PURGE in service mode to initialize (clear) the cleaning count information.
See:
For instructions on how to replace the main controller, see Disassembly/Reassembly > Tips on Disassembly/
Reassembly > PCB.
Counter information would not be available for viewing once it is initialized (cleared). You are warned not
to perform initialization before you view the counters.
The counters are not writable from the operation panel.

1.7.3.2 Confirming the Firmware Version

The main controller has firmware downloaded in it.
When the main controller has been replaced, make sure that the latest version of firmware is installed in it.
If not, upgrade the firmware to the latest version.
See:
For instructions on how to upgrade the firmware, see Troubleshooting > Upgrade.

1.7.3.3 Precautions against Static Electricity

Pieces of clothing rubbing each other could build up static electricity, producing static charges in human bodies
to cause harm to an electrical component or corrupt its electrical characteristics.
Before disassembling the printer for servicing, touch a positively grounded metallic object to neutralize static
charges in your body.
