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 you have the correct cartridge for your specific printer model.

 

Make sure that the toner cartridge is fully locked into place in the printer and fully seated.

 

To remove and install this toner cartridge into an Okidata B4300 do the following;

–          Press the top cover release button and open the printer’s top cover fully.

 

–          Pull the colored lever on the right side of the toner cartridge towards the front of the printer to close the cartridge then remove the used toner cartridge.

 

–          Insert the new toner cartridge into the printer installing the left end first

 

–          Lock the toner cartridge by pushing back the colored lever towards the rear of the printer.

 

–          With the top cover still open, use a lint-free, soft, dry, clean, cloth to gently clean the LED head (10) located under 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 may not be 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.
