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.

 

There’s a smart chip located on the front of each toner cartridge which has four gold connection points.  Make sure the chip is clean and undamaged.  You can use a dry, clean, lint-free cloth to clean the connections.

 

Make sure the cartridge is installed correctly and is fully inserted into the printer.  There are tabs on the sides of the cartridge and corresponding grooves inside the printer that will guide the cartridge into the correct position until it locks into place.

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

 

Holding the cartridge by its ends, gently roll the cartridge from left to right a few times to evenly distribute the toner powder inside the cartridge.

Leaking

 

This toner does not have any pull seal tabs and as a result a little toner dust on the cartridge is normal.  The protective paper that covers the toner roller has a piece of foam that covers the roller to help collect any loose toner dust.  However, vibrations during shipping may cause the roller 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.
