Dirty or Bad Primary Charge Roller (PCR); located Inside the cartridge, this will show on the test print as vertical gray

streaks down the page, as a gray background throughout the page, as ghosting where part of a previously printed area is

repeated, or as a mark that repeats every 38mm.

Dirty PCR Connection; This will show as horizontal dark black bars across the page, or as shading throughout the page.

Scratched Drum; This is shown by a very thin, perfectly straight line that runs from the top to the bottom of the test page.

Chipped Drum; This will show as a dot or series of dots that repeat every 75mm.

Light Damaged Drum; This will show up as a shaded area on the test print that should be white. Again this will repeat

every 75mm.

either case there will be a film of toner on the drum surface.

Machine Error Codes:

These machines do not have a display panel. They use a series of LED’s to indicate a problem. There are two lights on the

control panel, the POWER, and the ERROR lights. The POWER light is a Green LED, and the ERROR LED is a two color

LED, Red and Orange.

The user manual for these machines only has very basic information listed as follows:

If both lights are blinking, the machine has problems and needs service. (Helpful isn’t it!)

If the Error light is on steady red, and the power light is off, there could be a number of problems. Either there is a paper

am, the front cover is open, or the toner cartridge is not installed.

If the Error light is blinking orange, the printer is set to manual feed, and there is no paper in the tray.

If the Error light is on steady in Orange, that is the toner low message.
