Cause
What to do
One of the toner cartridges may be near the end of its
service life.
If the message on the LCD panel or in EPSON Status Monitor
indicates that one of the toner cartridges is near the end of its
service life, open cover D, make sure the cartridge is locked, and
tap the top of the toner cartridge about five times with your finger.
If the problem is not resolved, replace the toner cartridge. See
“Replacing Consumable Products” on page 133.
For Windows users, you can also check the remaining service life
of the toner cartridge by looking at the Basic Settings tab in the
printer driver.
There may be a problem with photoconductor units.
Replace the photoconductor units. See “Replacing Consumable
Products” on page 133.
The non-printed side of the page is dirty
Cause
What to do
Toner may have spilled onto the paper feed path.
Clean internal printer components by printing three pages with
only one character per page.
Print quality decreased
Cause
What to do
The printer cannot print in the required quality level
because of insufficient memory, and the printer lowers
the quality automatically so that the printer can continue
printing.
Check to see if the printout is acceptable. If not, add more memory
for a permanent solution or lower print quality temporarily in the
printer driver.
If
RAM Disk
is set to
Maximum
or
Normal
on the control panel, you
can increase the available memory space by changing this setting
to
Off
.
