Replacement of waste ink absorbers
The waste ink absorbers 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 absorbers and reset the waste
ink volume counter. Refer to page 4-22, Action for ##342, for details on how to reset the
waste ink volume counter.
