Replacing the Belt Unit
Recommendation for Replacing the Belt Unit
When the belt unit nears the end of its lifespan, the message
[Time to Replace Belt] will appear on the control panel to notify
you that it is time to prepare a new belt unit. You can continue
printing until the message [Replace Belt] appears, then printing
will stop.
The belt unit is recommended to be replaced after about
60,000 prints on A4-sized paper (single-sided printing).
However, this page yield is for common printing conditions (3
pages at a time). Printing one page at a time can reduce the
belt life by half.
Memo
• After the message [Time to Replace Belt] appears, you can
continue to print before the message [Replace Belt]
appears.
Note
• Even after the message [Replace Belt] appears, you may
still be able to print by opening and closing the top cover.
However, we recommend replacing the belt unit as soon as
possible.
