When time is about to come when the
Imaging Unit needs replacement, the
I.U. Service Life Indicator starts
blinking to prompt you to replace it
with a new one.
Replace the Imaging Unit by following
the procedure given below.
5,000 copies made
Whichever occurs first
After 2,500
Copies
Add Toner
Indicator lights up
Blinking
No new copy cycle
can be initiated.
When 2,500 more copies are made with Add Toner Indicator lighting up, or 7,500
more copies are made, after the I.U. Service Life Indicator has started blinking,
the I.U. Service Life Indicator lights up steadily and the copier inhibits the
initiation of a new copy cycle. See the diagram below.
Replace the Imaging Unit as soon as possible once the I.U. Service Life
Indicator has started blinking.
