NOTE: If cleaning the top surface of the glass does not remove all dirt and smudges from the glass, you can also clean the underside of the glass. Cleaning the underside of the glass requires that you disassemble the scanner. For instructions on how to clean the underside of the scanner glass, see www.hp.com/support.
Clean the transparent materials adapter (TMA)
Clean the TMA with a dry, soft cloth. If necessary, lightly spray the cloth with glass cleaner and wipe the TMA.
Clean the automatic document feeder (ADF)
The automatic document feeder (ADF) requires periodic maintenance depending on the amount of use and the type of paper that is fed through it. Clean the ADF under the following conditions:
•The ADF rollers are visibly dirty.
•The ADF has trouble feeding documents.
•Vertical streaks appear in images scanned by the ADF.
•After scanning a document that is dusty, dirty, or has pencil writing on it through the ADF.
•The environment is dusty.
If you use the ADF several times per week, monthly cleaning is recommended. Set up a cleaning routine that is appropriate for the scanner.
NOTE: If cleaning the automatic document feeder does not improve performance, you might need to replace the feed roller. To order a Roller Replacement Kit, see www.hp.com/buy/parts.
