Chapter 2: Assembly and Disassembly
Replacement of waste ink pads
The waste ink pads are designed to sop up any excess ink ejected during the cleaning
operation or during ink squirting for maintenance, in order to maintain the good printing
quality of the BJ cartridge.
The volume of ink absorbed is counted and these data stored
in the EEPROM on the PCNT board.
Once the volume is judged to have reached 100%,
the message
“CHECK PRINTER”
(error code ##342) will be displayed, and printing
will stop, in order to ensure that the volume of ink absorbed does not exceed the allowed
limit.
To clear this error, you need to replace the waste ink absorption pad and reset the
waste ink volume counter.
Refer to
page 3-28, Action for ##342,
for details on how to
reset the waste ink volume counter.
