THESE TONER CARTRIDGES DO NOT HAVE THE OPC DRUM INTEGRATED.  THE DRUM UNIT IS A SEPARATE, REPLACEABLE, MAINTENANCE ITEM FOR EACH COLOR.

There are 4 colors in this cartridge series; Black, Magenta, Cyan, and Yellow.

These are compatible cartridges so there will be differences from the OEM.  These differences will not affect function.

 

Not Recognizing

 

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

 

Make sure the correct color cartridge is installed into the correct color slot.

 

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

 

To remove and install these toner cartridges into the Konica Minolta Bizhub C20 machines do the following;

–          Open the front door to the printer.

 

–          Slide over the lock and pull down the cover to the color cartridge being replaced.  Remember to take note of the locations of the different colors.

 

–          Pull the cartridge out of the printer.

 

–          Make sure you have the correct color cartridge for the color you are replacing.  Insert the new cartridge into the correct color slot and push until it clicks into place.

 

–          Remove the pull tape seal from the cartridge.

 

–          Close the cover and slide the lock to the left.  Close the front cover.

 

Print Quality Issues

 

There is a pull tape seal which must be removed.  This pull tape seal should be removed once the cartridge is installed into the printer.

 

For any print quality issue you will want to try to determine if the problem is occurring with a specific color or if it is occurring across the board.  Check printed documents to see if the issue is only occurring where a specific color is.

 

Try shaking the cartridge up and down 3 times to loosen the toner inside.  Sometimes the toner powder can become compacted inside the cartridge.

 

This printer is constructed with four laser lenses.  If you are experience print quality issues you should clean all four laser lenses.  To clean the laser lenses do the following;

–          Open the printer’s front cover.

 

–          Remove the cleaning brush from the printer’s front cover.

 

–          Insert the laser lens cleaning brush into the laser lens cleaning opening, pull it out, and then repeat this back and forth movement 2 or 3 times.  Clean each of the laser lenses in the same way.

 

–          Return the cleaning brush to its holder on the inside of the front cover.  Close the front cover.

 

Streaking, lines, ghost imaging, and repeating image defects are drum related issues.  There is a separate, individual, drum unit for each color.  These drum units will need to be replaced after a certain period of usage.  If the above cleaning did not resolve the issue then the drum unit for colors exhibiting the issue may need replacing.

 

Not Fitting

 

Verify you have the correct cartridges for your specific printer.  Make sure the correct color is being installed into the correct color slot.  Check inside the printer for obstructions.  Check the cartridge itself for physical damage.
