Replacing a Print Unit Assembly 95
Replacing a Print Unit Assembly
The print unit assembly consists of the print unit and its corresponding color
toner cartridge.
You do not need to reset the consumables usage monitoring system
when you replace a print unit assembly.
Print Unit Life
Characters and images are created in your laser printer through a
photosensitive process that applies toner to the Optical
Photo Conductor
(OPC) (which functions like photographic film). Each print unit contains an
OPC, and a developer that form the image that is developed and transferred
to the media. The full print unit assembly also includes a same-color toner
cartridge.
Print unit life is directly related to the number of rotations of the OPC. Longer
life is achieved with continuous printing. Intermittent printing with small-sized
jobs requires automatic cleaning rotations before and after each job, which
impacts print unit life.
The number of pages that can be printed differs depending on the
image and size being printed in addition to other printing conditions.
Attention
The print units are extremely sensitive to bright light, direct sunlight,
and touch. Always leave the print 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 print units are damaged due to exposure to light, put
the entire print 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 print units
will void the warranty of the print units.
When the print unit is low, the message P-UNIT LOW KCMY ( KCMY = color)
appears. You will need to replace the print unit soon.
When the print unit is worn out, the message PRINT UNIT END/REPLACE
KCMY ( KCMY = color) appears. The printer will not print until the print unit and
its same color toner cartridge are replaced. After the print unit assembly is
replaced, the printer automatically resets the consumables count.
