• Replace with new imaging unit
The indicated imaging unit has almost
reached its estimated imaging unit life.
Estimated imaging unit life means
the expected or estimated
imaging unit, which indicates the
average capacity of print-outs and
is designed pursuant to ISO/
IEC 19752. The number of pages
may be affected by the
percentage of image area,
operating environment, printing
interval, media type and media
size. Some amount of toner may
remain in the cartridge even when
red LED is turns on and the printer
stops printing.
• You can choose Stop or Continue as shown on the
control panel. If you select Stop, the printer stops
printing and you cannot print any more without
changing the imaging unit. If you select Continue,
the printer keeps printing but the printing quality
cannot be guaranteed.
Replace the imaging unit for the best print quality
when this message appears. Using a imaging unit
beyond this stage can result in printing quality
issues (see "Replacing the imaging unit" on page 63).
Samsung does not recommend using non-
genuine Samsung imaging unit such as
refilled or remanufactured. Samsung cannot
guarantee non-genuine Samsung toner
cartridge's quality. Service or repair required
as a result of using non-genuine Samsung
imaging unit will not be covered under the
machine warranty.
• If the machine stops printing, replace the imaging
unit (see "Replacing the imaging unit" on page 63).
