2.8 Roller Cleaning

If surface-processed paper or High-Resolution Paper (HR-101) has been used in
quantity, paper feeding performance may decline due to paper dust adhering to the
pick-up roller. If this happens, clean the pick-up roller using the cleaning plate
supplied with the printer.
Clean the roller in the following procedure:
1) Dampen the white cleaner on the cleaning plate with adequate water and set the
plate into the automatic feeder.
2) From the service function selection status as shown in
Operations,"
3) The pick-up roller will rotate 20 times.
(The printer returns to service function selection status)
4) Insert a sheet of plain paper into the printer, with the cleaning plate set. The paper
should be inserted all the way until the front edge of the paper contacts the inside of
the printer.
5) Press the RESUME button 9 times to select "Plain paper feeding/ejection after roller
cleaning" and press the POWER button to perform the paper feeding/ejection.
6) Carry out steps 4) and 5) once again.

water.
