Cleaning the Feed Path
Dust or paper particles in the document feed opening or inside the scanner
can cause lines in scanned images. Use compressed air to periodically
clean dust and paper particles from the document feed opening and the
inside of the scanner. After finishing a large scanning job, turn OFF the
scanner and then clean out any paper particles.
Cleaning the Sensor Glass and the Rollers
If scanned images have extraneous marks, or if the scanned documents
are dirty, the sensor glass or rollers inside the scanner may be dirty. Clean
them periodically.
IMPORTANT
Feed rollers are consumable parts. When the rollers start to wear
out, paper jams and misfeeds may occur more often. When this
happens, purchase an exchange roller kit and replace the roller unit
and the retard roller.
1 Carefully open the upper unit until it stops.
IMPORTANT
When opening the upper unit, do not grasp the roller unit in the
center. Doing so may distort the rollers and lead to feeding errors.
