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 the you have the correct cartridge for your specific printer.

 

There is a smart chip located on the front of the toner cartridge behind plastic slots.  Check to make sure the four gold contacts are clean and free of debris.  A Q-tip can be used to reach within the slots to clean the chip contacts.

 

Ensure that the cartridge is installed correctly and fully inserted into the printer.  Tabs on the sides of the cartridge and corresponding grooves within the printer will guide the cartridge into the correct position until it locks into place completely.

Print Quality Issues

 

There is a piece of paper with foam that protects the OPC drum that must be removed prior to installation.

 

The OPC drum is located on the bottom 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.  Do not use moisture of any kind.  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.  Be careful with setting the cartridge down on a surface because being that the OPC drum is located on the bottom of the cartridge it can easily be scratched or nicked.

 

Holding the cartridge by its ends gently shake horizontally a few times to make sure the toner powder is evenly distributed 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 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.
