Replacing The Fuser Unit - Oki MC780fx User Manual

Replacing the Fuser Unit

Recommendation for Replacing the Fuser Unit
When the fuser unit nears the end of its lifespan, the message
[Time to Replace Fuser] will appear on the control panel to
notify you that it is time to prepare a new fuser. You can
continue printing until the message [Replace Fuser] appears,
then printing will stop.
The fuser unit is recommended to be replaced after about
100,000 prints on A4-sized paper (single-sided printing).
Memo
• After [Time to Replace Fuser] appears, about another 1,250
A4 sheets can be printed (simplex printing) until [Replace
Fuser] appears.
Note
• Even after the message [Replace Fuser] appears, you may
still continue to print by opening and closing the top cover;
however, this may lead to paper jams and other problems.
We recommend replacing the fuser unit as soon as
possible.
