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.
