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

Not Recognizing

 

Verify you have the correct cartridge for your specific printer.

 

There is a smart chip located on the front of the cartridge.  Check the chip for damage or debris.  You can use a Q-tip to reach and clean the four gold contacts.

 

Make sure the cartridge is installed correctly and is fully inserted into the printer.

Print Quality Issues

 

There is a pull tape seal on the side of the cartridge which must be removed prior to installation.  It is important that this pull tape seal is fully removed from the cartridge.  If the cartridge is printing blank pages then the pull tape seal probably hasn’t been removed or has broken off inside the cartridge while being removed.

 

Holding to the ends of the cartridge, gently shake from side to side five or six times to redistribute the toner inside the cartridge.

The OPC drum is located on the bottom of the cartridge protected by a spring loaded plastic shutter.  Lift the shutter to view the OPC drum.  Do NOT touch the drum.  Visually inspect the OPC drum for damage or debris.  A soft, clean, dry, lint-free cloth can be used to gently wipe the OPC drum if needed.  Do NOT use moisture of any kind.
