THIS IS A TONER THAT HAS THE OPC DRUM BUILT INTO THE CARTRIDGE ITSELF AND IS REPLACED AS ONE WHOLE UNIT.  THERE IS NO SEPARATE DRUM UNIT.

Not Recognizing

 

Verify you have the correct cartridge for your specific printer model.

 

Samsung has a reputation of doing stealth firmware updates, where they disguise a firmware update as a routine update.  A firmware update may lock out the use of aftermarket cartridges.  Usually when a firmware updates goes through cartridges that were once working will no longer read and/or a cartridge gives an incompatible error and you try others (reships, multiples in the same order, etc) which also won’t recognize.  We recommend not updating your printer’s software or firmware when using our cartridges to prevent them being locked out.

 

There is a smart chip located on the side of the cartridge.  Check to make sure it is not damaged and that it is free of debris.  You can use a clean, dry, lint-free cloth or Q-tip to gently clean the 4 gold connection points.

 

Verify that the cartridge is installed correctly and fully inserted into the printer.

 

Leaking

 

This toner does not have any pull seal tabs and as a result a little toner dust on the cartridge is normal.  The paper that protects the OPC drum during shipping has a piece of foam that covers the OPC drum to help collect any loose toner dust.  However, vibrations during shipping may cause the OPC drum to rotate a little and allow a little toner powder to leak.  This is normal.  You can clean excess toner dust off the cartridge by gently wiping the cartridge with a clean, dry, lint-free cloth or gently blowing on it.  Be careful with compressed air as this may blow too powerfully and blow toner powder out of the cartridge.

 

Print Quality Issues

 

There is a piece of paper held on by tape that protects the OPC drum.  This must be removed prior to installation into the printer.

You can print a demo page to see print quality issues by; In the ready mode, press and hold the button on the printer that has a picture of a computer monitor and a sheet of paper inside a circle for about 10 seconds until the green LED blinks slowly, and release.

 

Holding the cartridge by its ends, gently rock the cartridge left to right to evenly distribute the toner power inside the cartridge.

The OPC drum is located on the front of the cartridge.  Visually check for scratches or debris on the drum.  Do NOT touch the OPC drum.  If need be, clean the OPC drum using a dry, soft, lint-free cloth.  There is no protective drum shutter on this cartridge to protect the OPC drum so caution must be taken in handling this cartridge to prevent damage to the drum.  Do NOT use moisture of any kind.
