HP Color LaserJet 4730 Multifunction Printer series - Manual (Page 249)

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.
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
● One mylar sheet kit
● An instruction sheet
Follow the instructions that come with the kit to install it.
After replacing the kit, reset the ADF maintenance-kit count.
To reset the ADF maintenance-kit count
1. Turn the MFP off and then on.
2. When XXXMB appears on the control-panel display, press and hold 6 until all three LEDs flash
once and then stay on. (This might take up to 20 seconds.)
3. Release 6 and then press 3 twice.
4. Press 6 to select NEW DOCUMENT FEEDER KIT.
5. The MFP completes its initialization sequence. The ADF maintenance-kit counter is automatically
reset.
