Ink is used for cleaning operation as well as printing. When ink is used for
cleaning, the ink is drained to Waste Ink Pad (Ink Absorber Tray Assembly) and
the amount of waste ink is recorded in the EEPROM on the MAIN board.
Due to this, when the waste ink has reached the limit of the absorbing capability of
the Waste Ink Pad, Unknown Error is indicated on Status monitor 3 as following
figure.

In this case, replace the Waste Ink Pad and clear the Waste Ink Counter stored in
EEPROM. Waste Ink Counter can be reset only from the Adjustment program because
this printer dose not have control panel. As for the procedure, refer to Chapter 5
