Replacing the Imaging Unit
Attention
The OPCs are extremely sensitive to bright light, direct sunlight, and
touch. Always leave the imaging unit in its protective package until
you’re ready to install it. Any exposure to light should be avoided and
limited to less than two minutes, or permanent damage could result.
If you suspect the OPCs are damaged due to exposure to light, put the
entire imaging unit in a dark place to recover. Depending on the amount
of exposure, recovery may take up to two hours. Recovery time is
dependent on the amount of exposure sustained, and recovery is not
guaranteed. Any damage resulting from mishandling of the OPCs will
void the warranty of the OPCs.
How do I replace the imaging unit?
WARNING!
The fuser unit is hot and can cause severe burns. When the
printer’s front cover is opened, the fuser unit temperature drops
gradually. Wait one hour after opening the front cover.
The imaging unit contains 4 OPCs (Optical
Photo Conductors), 4 developers, and an
imaging unit transjnfer roller that forms the
image that is developed and transferred to the
media. When the imaging unit is worn out, the
message
REPLACE IMAGING UNIT appears. After
the imaging unit is replaced, the printer automatically
resets the consumables count. Imaging unit life is directly
related to the number of rotations of the OPCs. Longest unit life is
achieved with continuous printing or minimum 4-page job size. Intermittent
printing with small job sizes requires a cleaning rotation after each one-page
simplex job, and therefore impacts OPC life.
