Replacing Toner Cartridge or Image Drum
If the ES7131/MPS5501b is
used
Life Span of a Toner Cartridge
When the [Toner Low] message is displayed on
the display screen of the operator panel, prepare
a replacement toner cartridge.
If you continue printing, the message [Install
toner] will be displayed and printing will stop.
Approximately 250 sheets may be able to
be printed after [Toner Low] is displayed
until [Install toner] is displayed (when ISO/
IEC19752 print-pattern printing).
Life Span of an Image Drum
When the [Image Drum Near Life] message is
displayed on the display screen of the operator
panel, prepare a replacement image drum.
If you continue printing, the message [Image
Drum Life] will be displayed and printing will
stop.
Approximately 500 sheets may be able to be
printed after [Image Drum Near Life] is
displayed until [Image Drum Life] is displayed
(when single-sided printing is performed on A4-
sized paper with 3 sheets at a time).
If you continue to print more than the above,
the printer will force the printing to stop.
Note
The actual number of sheets you can print with the image
drum depends on how you use it. The above guideline
may be reduced by more than half, depending on the
conditions of printing.
Though opening and closing the top cover may extend the
life of an image drum for a while, it is recommended to
replace it soon after the [Image Drum Life] is displayed.
The print quality may deteriorate after an image drum has
been unpacked for a year. Replace it with a new one.
When [Near Life Status] (to be accessed by pressing
the button then selecting [Admin Setup] then [Panel
Setup]) is set to [Disable], the [Image Drum Near
Life] message does not appear.
