(3) Waste ink counter setting Before replacement of the logic board ass'y, check the waste ink amount. After the logic board ass'y is replaced, set the waste ink amount to the replaced logic board ass'y. In addition, according to the waste ink amount, replace the waste ink absorber (ink absorber kit). When the waste ink absorber is replaced, reset the waste ink counter (to "0%"). How to check the waste ink amount: See 3-4. Verification Items, (1) Service test print, or (2) EEPROM information print. How to set the waste ink amount: See 3-3. Adjustment / Settings, (8) Service mode, "Waste ink amount setting." (4) White sponge sheet attachment Position one of the corners of the white sponge sheet at the scanning reference point on the platen glass (back left where the blue lines cross in the photo below). Peel off the cover sheet from the double-sided adhesive tape, and slowly close the document cover with the sponge frame on. The sponge sheet will attach to the sponge frame. Open the document cover to confirm the following: - No extension of the sponge edges over the mold part of the document cover. - No gap between the platen glass reference edges and the corresponding sponge edges. (5) Solenoid position Position the solenoid so that the solenoid shaft is parallel to the tray lock lever operation axis. Move the tray lock lever right and left to confirm that the solenoid shaft moves smoothly. (For cable position, see the photo on the right.) 1-26

Waste ink counter setting
Before replacement of the logic board ass'y, check the waste ink amount. After the logic board ass'y is replaced, set the waste
ink amount to the replaced logic board ass'y.
In addition, according to the waste ink amount, replace the waste ink absorber (ink absorber kit). When the waste ink absorber is
replaced, reset the waste ink counter (to "0%").
