SAMSUNG ML 2250 • CARTRIDGE REMANUFACTURING INSTRUCTIONS
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) 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 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 76mm.
Light Damaged Drum
This will show up as a shaded area on the test print that should be white. Again this will repeat every 76mm.
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 44mm.
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, 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 on 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.
