Suggested solutions
• 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 100).
• If the machine stops printing,
replace the imaging unit (see
"Replacing the imaging unit" on
page 100).
Install the corresponding toner
cartridge with a Samsung-genuine
cartridge (see "Replacing the toner
cartridge" on page 97).
