Replacing the Fuser Unit and Transfer Roller
Life Span of a Fuser Unit and a
Transfer Roller
When the [
Fuser Unit Near Life
] message is
displayed on the display screen of the operator
panel, prepare a new fuser unit and a transfer
roller. You can keep printing approximately 3,000
sheets until the next message is displayed.
When [
Fuser Unit Life
] is displayed, replace
the fuser unit and transfer roller.
The life expectancy of the fuser unit and transfer
roller is up to 200,000 sheets for A4 simplex
printing.
Note
●
The actual number of sheets you can print with the fuser
unit and transfer roller depends on how you use the
printer.
●
Though opening and closing the top cover may extend the
life of the fuser unit and transfer roller somewhat, you
should replace it soon after [
Fuser Unit Life
] is displayed
to prevent malfunction.
●
If you replace the fuser unit and transfer roller, use them
until the end of their usable lives. If you remove the
fuser unit and/or transfer roller before their usable lives
have expired and install and use for another printer, their
usable lives will not be correctly displayed.
●
When [
Near Life Status
] (to be accessed by pressing
the button then selecting [
Admin Setup
] then [
Panel
Setup
]) is set to [
Disable
], the [
Fuser Unit Near Life
]
message does not appear.
