•Feed roller
Follow the procedure below while rotating the Feed rollers to
clean the rollers.
1) Open the ADF by pushing on the ADF button and
turning the ADF cover to the front.
Open the ADF cover with the operator panel
indicating anything other than "P" or "0". The Feed
rollers do not rotate even if you open the ADF cover
with "P" or "0" displayed and perform step 2).
2) Simultaneously hold down the "Send to" and "Scan"
buttons on the operator panel.
The Feed rollers start to rotate slowly.
For details on where the "Send to" and "Scan" buttons
are located, see "1.3 Operator panel."
3) Hold a soft, dry cloth moistened with cleaning fluid
against the surface of the rotating Feed rollers so that
it lightly cleans the surface of the rollers. Take
particular care when cleaning these rollers as black
foreign matter on these rollers affects document pick
performance.
As a guideline, seven simultaneous presses of the
"Send to" and "Scan" buttons cause the Feed rollers
to rotate one full turn.
CAUTION
In step2, four Feed rollers turn at
the same time.
When cleaning the Feed roller,
be careful as your hand may
