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 they have the correct cartridge for their specific printer model.

 

There is a smart chip located on the front 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.

 

Check to make sure the cartridge is installed correctly and fully inserted into the printer.  There are tabs on each side of the print cartridge that align with slots on each side of the print cartridge cradle inside the printer.  Slide the print cartridge into the printer until it snaps into place.

 

To remove and install the toner cartridge in a Lexmark T620 series printer do the following;

–          Push the release latch and open the printer upper front door.  Grasp the print cartridge by the hand grip and pull the print cartridge up and out.

 

–          Align the slides on the new print cartridge with the slots on the print cartridge cradle.  Use the colored arrows inside the printer for placement.  Guide the print cartridge down as it drops and snaps into place.

 

–          Close the upper front door.

 

Print Quality Issues

 

There is a red plastic protective piece that must be removed prior to installation.  There is also a piece of blue plastic covering the OPC drum on the bottom which must be removed.  Be careful not to touch the OPC drum and be careful setting the cartridge down on a surface as the OPC drum can be easily nicked or damaged.

 

Make sure the blue plastic protective cover is removed from the cartridge.

 

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

 

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.

 

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.

 

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 they have the correct cartridge for their specific printer model.  Check to make sure all the seals 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.
