SAMSUNG ML-2250 TONER CARTRIDGE REMANUFACTURING INSTRUCTIONS

PRINTING TEST PAGES

Test pages from these machines are very easy to run. Timing is the only issue here.

NOTE: All of the following are based on the ML-2250. Other branded machines may be different.

Demo Page: Press and hold the “CANCEL” button for two seconds. A demo page will print out.

Configuration Page: Press and hold the “CANCEL” button for six seconds. The configuration page will print out.

Cleaning Page: Press and hold the “CANCEL” button for 10 seconds. The cleaning page will print out.

COMMON CARTRIDGE PROBLEMS

Even Light Prints: Check to see if the Toner Save feature has been enabled. The Toner Save light will be on. This is accessed from

the printer driver properties.

Dirty or Bad Primary Charge Roller (PCR) Inside 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 will show 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 76 mm.

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

every 76 mm.

Bad Wiper Blade: This will show as either a gray line approximately 1/8" thick, or as shading across the entire page. In either

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

Bad Developer Roller: This will show up as light print or as a mark that repeats every 44 mm.

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 ONLINE/ERROR Light, and the TONER SAVE Lights The Online Light is a two-color LED (Red and Green).

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

1. If both lights are blinking, the machine has problems and needs service.

2. If the ONLINE light is on steady RED, and the toner save light is off, there could be a number of problems. Either there is a

paper jam, the front cover is open, or the toner cartridge is empty.

3. If the ONLINE light is blinking GREEN, and the toner save light is off, there could also be a number of problems or reasons.

If the printer is receiving data, the ONLINE/ERROR LED will blink slowly. If the printer is printing, the ONLINE/ERROR LED will

blink fast. The ONLINE/ERROR will also blink if it is in the manual feed mode, and no paper is in the manual feeder, or if the

CANCEL button was pressed while the printer was receiving data.
