Image transfer kit
The image transfer kit contains the following parts: the transfer roller, the transfer belt, one filter, one toner wipe, two small
tray rollers, and seven large tray rollers.

the MFP stops printing until the kit is replaced and the count is reset at the control panel.
Hewlett-Packard Company recommends that you place an order for a replacement image transfer kit when the ORDER
TRANSFER KIT message first appears on the control-panel display.
The part number for the image transfer kit for the HP Color LaserJet 9500mfp is C8555A.
