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."

against the surface of the rotating Feed rollers so that

it lightly cleans the surface of the rollers. Take

performance.

As a guideline, seven simultaneous presses of the

"Send to" and "Scan" buttons cause the Feed rollers
