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.

 

Not Recognizing

 

Verify they have the correct cartridge for their specific printer model.

 

This cartridge uses a RF or radio frequency sensor chip. This chip does not make physical contact with the printer but rather sits in a specific position to be picked up by the printer’s sensor. Make sure that the cartridge is properly inserted and locks into place to ensure the chip is in the correct position. If the problem persists it is most likely an issue with the chip on the cartridge.

 

Make sure the cartridge is fully locked in the printer and that it is fully inserted.

 

To install the cartridge in an Okidata B4300 do the following;

–          Press the cover release button and lift the cover.

 

–          Pull the toner lock lever towards you to unlock the toner cartridge.  Remove the toner cartridge from the drum unit.  Be sure not to remove the drum unit along with the toner cartridge.

–          Place the left edge of the new toner into the image drum.  Lower right edge aligning slot (1) on shaft (2).

 

–          Push the lock lever down to lock the toner into the drum unit.

 

–          Close the top cover.

 

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 you have the correct cartridge for your specific printer model.  Verify you are installing the toner cartridge into the pre-existing drum unit.  If the cartridge appears too small then you 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.
