Copy Image Problems

If copies appear either too dark or too light and you can not get a clear copy, refer to the guidelines below.

If Light Bands/ White Streaks Appear on Copies

This most often happens when the cartridge toner is low or not evenly distributed in the cartridge. To help distribute the toner in the cartridge, remove it from the copier and rock it several times to the left and right at a 90˚ angle. If the white streaking continues then replace the cartridge with a new one.

(See “Replacing Cartridges”, on p. 21.)

Paper feeding direction

If Dark Bands/ Black Streaks Appear on Copies

When this happens follow the procedure below to clean the fiber lens. If the problem persists after cleaning the fiber lens, then replace the toner cartridge.

Cleaning the fiber lens (top side)

Turn the power switch OFF and unplug the copier.

Align the platen with the mark by sliding it to the left.

Fiber lens (top side)

Clean the top side of the fiber lens. To clean, run a cotton swab (not included) over the entire length of the lens several times.
