Appendix B — Using the document feeder option 46
Maintaining the document feeder option
Cleaning and replacing the guide flap
The guide flap on the underside of the ADF keeps documents at the correct scanning position and
guides them into the output tray after scanning. To prevent printing ink and other contaminants from
accumulating on the flap and interfering with image quality, wipe it periodically with an ink-free cloth
or swab cotton swab moistened with industrial alcohol.
After prolonged use, the surface of the flap may become scratched. This causes lines to appear in
scanned images that can create OCR errors. Should the scratches appear, detach the flap and
replace it by a new one. For a new guide flap, please contact your dealer.
Roller cleaning
Prolonged use of the ADF may result in accumulation of ink and other contaminants on the feeder's
input roller, reducing the roller's efficiency. Check for dirt on the roller if the ADF starts to have
trouble pulling paper through properly. The input roller should be cleaned periodically using a lint-
fee cloth or swab moistened with ethylene chloride.
❖ Note: Do not attempt to turn the roller while cleaning it; this may damage the ADF's drive
mechanism.
