HP Color LaserJet Enterprise M855 - User Guide

Replace the imaging drums
The product uses four colors and has a different imaging drum for each color: black (K), cyan (C), magenta
(M), and yellow (Y). The product also has four toner cartridges that are separate from the imaging drums. The
toner cartridges are above the imaging drums. The toner cartridges and imaging drums are inside the front
door. A toner cartridge and its associated imaging drum are replaced independently of each other.
This product indicates when the imaging drum life is low. The actual imaging drum life remaining can vary.
The imaging drum does not need to be replaced at this time. Consider having a replacement imaging drum
available to install when print quality is no longer acceptable.
The following illustration shows the imaging-drum components.

3 Photosensitive drum
CAUTION: Do not touch the photosensitive drum. Fingerprints on the drum can cause print defects.
CAUTION: If toner gets on clothing, wipe it off by using a dry cloth and wash the clothes in cold water. Hot
water sets toner into fabric.
NOTE: Information about recycling used imaging drums is on the imaging-drum box.
