HP LaserJet 4345 Multifunction Printer series - Manual (Page 193)

Performing preventive maintenance
The MFP requires periodic maintenance to maintain optimum performance. A control-panel
message alerts you when it is time to purchase the preventive maintenance kits. Separate
maintenance procedures are required for the printer-portion of the MFP and for the ADF.
Printer preventive maintenance
You should replace certain parts when the PERFORM PRINTER MAINTENANCE message
appears on the control-panel display.
The maintenance message appears every 200,000 pages. The message can be temporarily
cleared for approximately 10,000 pages by using the CLEAR MAINTENANCE MESSAGE
item on the RESETS submenu. (See
Resets submenu .) To check the number of pages that
the MFP has printed since new maintenance-kit components were installed, print either a
configuration page or a supplies status page. (See
Checking the MFP configuration or
Checking the MFP configuration for details.)
To order the printer maintenance kit, see Part numbers . The kit includes:
● Fuser
● Rollers (transfer, pickup, and feed)
● Installation instructions
Note The printer maintenance kit is a consumable item and is not covered under the original
printer warranty or under most extended warranties.
After a maintenance kit is installed, the maintenance-kit counter must be reset.
To reset the maintenance-kit counter
1. Touch Menu.
2. Touch CONFIGURE DEVICE.
3. Scroll to and touch RESETS.
4. Touch RESET SUPPLIES.
5. Touch NEW MAINTENANCE KIT. The maintenance-kit counter is automatically reset.
Note Perform this procedure only after a maintenance kit has been installed. Do not use this
procedure to temporarily clear the PERFORM PRINTER MAINTENANCE message.
The ADF maintenance kit
After feeding 90,000 pages through the ADF, a REPLACE DOCUMENT FEEDER KIT
message appears on the control-panel display. This message appears approximately one
month before the kit needs to be replaced. Order a new kit when this message appears. See
Part numbers for information about ordering a new ADF maintenance kit.
The ADF maintenance kit includes the following items:
● One pick-up roller assembly
● One separation pad
