When replacing the PCNT board, check to make sure that the PCNT sheet is found.
Otherwise, purchase a PCNT sheet (HC1-0165), and attach it before mounting the board
to the machine.
Attaching the PCNT Sheet
When attaching the PCNT sheet, place the sheet in proper position by doing as follows:
Butt the PCNT sheet against the paper edge sensor located on the left part on the PCNT
board, and fit the pickup sensor on the right part on the PCNT board into the notch in the
PCNT sheet. Moreover, when mounting the PCNT board after attaching the PCNT sheet,
make sure that the PCNT sheet is inside the PCNT cover.
PCNT board replacement
The PCNT board EEPROM is for storing data on the volume of waste ink absorbed and
vertical line displacement correction data. When replacing the PCNT, you should confirm
the waste ink volume from the system dump list and make a note of it. Then, after you
have replaced the board, enter this value and perform vertical line displacement
correction.
