3.12 Maintenance
Cleaning the document scanner
To keep your machine working properly, occasionally clean the white roller,
ADF (automatic document feeder) rubber, and the scanning glass. If they
are dirty, documents sent to another fax machine will not be clear.
1. Open the control panel with hand.
3. Disassemble the white roller as follows:
Both ends of the white roller have plastic bushings that are snapped shut
with small tabs on them. Pull the bushing slightly inward (A) , then
rotate the bushing (B) until it reaches a slot. Then pull the roller upward.
