Throughout this document, the term "printer" is used to refer to both the HP LaserJet 9500 Series printer models and the HP LaserJet 9500mfp. Make sure to read the headings and text carefully to understand the context of the term. The image transfer, image cleaning, and image fuser kits are used in a preventative maintenance routine for the printer. Image transfer kit The image transfer kit (part number C8555-67901) contains the following parts: the transfer roller, the transfer belt, one charcoal filter, one toner wipe, two small tray rollers, and seven large tray rollers. The image transfer kit should be replaced after every 200,000 pages of printing. When the counter reaches 200,000 pages, the printer stops printing until the kit is replaced and the count is reset at the control panel. Hewlett-Packard 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.

Storing the image transfer kit z Do not remove the image transfer kit from its package until you are ready to use it.
