THIS TONER CARTRIDGE DOES NOT HAVE INTEGRATED DRUM UNIT.  THE DRUM IS A SEPARATE UNIT FROM THE TONER CARTRIDGE.

This is a compatible cartridge so there will be differences from the OEM cartridge.  These differences will not affect the function of the cartridge.

Print Quality Issues

 

There is a white piece of plastic tape that covers the toner shutters on the cartridge which must be removed prior to installation.

 

Try rocking the cartridge back and forth a few times to redistribute the toner powder inside the cartridge.

 

Verify the cartridge is locked into the drum unit properly.  Moving the lock lever to the back of the printer opens the toner shutters on the bottom of the cartridge which drops the toner into the drum unit.

 

Ghosting, lines, streaking, and repeating defects will be a drum related issue.  The drum unit is separate from the toner cartridge and is a replaceable, maintenance item.  After a certain period of usage the drum will need replacing.

 

Not Fitting

 

Verify they have the correct cartridge for their specific printer model.  Verify they are installing the toner cartridge into the pre-existing drum unit.  If they are saying the cartridge is too small then they are not installing the toner into the drum unit.

 

Make sure that the cartridge is locked properly in the drum unit.  Verify that the white protective tape has been removed from the cartridge.
