Epson AcuLaser MX20DNF - Manual (Page 233)

The printed image is light or faint
Cause What to do
Your paper may be moist or damp. Do not store your paper in a humid or damp environment.
The Toner Save mode may be on. Turn off the Toner Save mode using the printer driver or the
printer’s control panel menus.
For Windows users, on the Basic Settings tab in the printer driver,
click Advanced and select the More Settings button. Then
deselect the Toner Save check box.
The toner cartridge may be near the end of its service
life. If the message on the LCD panel or in EPSON Status Monitor
indicates that the toner cartridge is near the end of its service life,
replace the toner cartridge. See “Replacing Consumable
Products/Maintenance Parts” on page 194.
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 toner cartridge. Replace the toner cartridge. See “Replacing Consumable
Products/Maintenance Parts” on page 194.
The Density setting may be too dark. In the printer driver, click Extended Settings on the Optional
Settings tab, and then lighten the Density setting.
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.
Printing was made right after clearing the paper jam. Make a few one-sided printouts.
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.
