Cleaning the HP Digital Copier Clean the ADF Assembly, including the Rollers and Separation Pad, every 6,000 pages, or more frequently with certain paper types. To check the “ADF Scans Since Last Cleaning” counter, print a Configuration Page from the Printer Information Menu. You must reset the cleaning counter in the printer’s service mode after you clean the copy module (see page 143). Symptoms indicating that it is time to clean the copy module include increasing mispicks and an optical failure.
Materials G Dry, lint-free cloth G Isopropyl alcohol (any concentration, including denatured alcohol) G Vacuum (see below) G Blow brush G Glass cleaner (for flatbed glass only) G Terrace Oil 46 (light weight oil) G Alvania Grease No. 2 (white or silicone grease) CAUTION Do not use organic solvents such as thinner. Never use glass cleaner on any part of the copy module except the flatbed glass. Be sure no liquid enters the copy module from the edges of the Glass Plate Assembly. (See page 551.) Vacuum Specifications Use the same type of vacuum used for printer maintenance. Be sure to use a vacuum with adequate filtration so that microfine toner is not released into the air.
Paper dust and unfused toner particles can accumulate in the ADF and on the Carrier Unit. The type of narrow attachments that are used with printer and copier machine vacuums are particularly useful for cleaning. CAUTION When using the vacuum be careful not to damage paper sensors. Never use the vacuum for the Carrier Unit or Optical Unit. These should be hand cleaned only. C4265-90907 Cleaning the HP Digital Copier 161
