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

 

Not Recognizing

 

Verify you have the correct cartridge for your specific printer model.

 

There is a smart chip located on the side of the cartridge.  Check the chip for damage or debris.  A clean, dry, lint-free cloth can be used to gently wipe the gold contacts.

 

Verify that the cartridge is fully inserted into the printer and that the printer cover is fully closed.

 

To remove and install this toner into a Lexmark E321 Series printer do the following;

–          Use the finger tab to pull down the printer cover.

 

–          Grasp the cartridge handle and pull the print cartridge straight up.

 

–          Align the colored arrows on either side of the print cartridge with the corresponding arrows in the printer.  Holding the handle, tilt the cartridge down and guide it between the print cartridge grooves.  Push down on the cartridge until it is firmly in place.

 

–          Close the printer cover.

 

Print Quality Issues

 

There is a red plastic protective piece that must be removed prior to installation.  There’s also a piece of foam that surrounds the cartridge which must be removed.  Be careful not to touch the OPC drum on the bottom of the cartridge.

 

There’s a piece of plastic blue film that covers the OPC drum on the bottom of the cartridge which must be pulled off before installing the cartridge into the printer.

 

Try gently rocking the cartridge a few times to evenly re-distribute the toner powder inside the cartridge.

 

The OPC drum is located on the bottom of the cartridge.  Be careful with placing the cartridge down on a surface as the OPC drum is easily nicked, dented, or damaged.  Visually inspect the OPC drum for damage or debris.  Do NOT touch the OPC drum.  A soft, lint-free, dry, clean cloth can be used to gently clean the drum.  Do NOT use moisture of any kind.

 

If the toner is smearing off the paper or isn’t adhering properly, make sure the paper settings on the printer match the paper type being used.  Thicker paper, such as labels or bonded paper, require a different paper setting to allow more heating while printing to ensure the toner melts properly to the paper.  Trying to print on thicker paper while under that standard paper setting will cause the toner not to get enough heat to melt properly.

 

Compressed air can be used to clean inside the printer with the toner cartridge removed.  Excess toner powder build up inside the printer can cause dots, excess loose toner on the page, or noises and blowing compressed in the printer can help clear out the excess toner dust.  Do NOT use moisture of any kind.

 

Not Fitting

 

Verify you have the correct cartridge for your specific printer model.  Check to make sure all the seals and protective clips have been removed from the cartridge.  Check inside the printer to see if there’s any debris that may be causing the cartridge not to fit.  Make sure the cartridge is being installed into the guides built into the inside of the printer.
