120 Troubleshooting Chapter 4
Printout Has Black Specks
If toner powder adheres to the pressure roller, black specks 1 mm in
diameter or larger might appear on the front or back of the printed paper.
Corrective action
1. Use the Options menu in the Status Window to print the cleaning
page on a blank sheet of paper.
2. If there are no black specks on the cleaning page, the pressure roller
is clean.
3. If there are black specks on the cleaning page, repeat step 1 until
there are no black specks on the cleaning page. You may repeat this
procedure several times with no adverse effect on the printer.
Printout Too Light
This occurs with high-volume printing in a hot environment.
Corrective action
1. Increase the printing density.
2. If this has no effect, replace the EP-22 cartridge.
Printout Too Dark
If there is a strong light source near the printer, the prints may be too
dark.
Corrective action
1. Check whether the density adjustment is correct. If not, adjust the
density.
2. Check whether there is a strong light source near the printer. If there
is, move the printer or the light source.
