THIS TONER CARTRIDGE DOES NOT HAVE THE OPC DRUM INTEGRATED.  THE DRUM IS SEPARATE.

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

These are compatible toner cartridges so there will be some 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 is being installed into the correct color slot.

 

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

 

Verify that the cartridge is fully inserted into the printer and locked into place.

 

Print Quality Issues

 

Try shaking the cartridge from left to right and up and down a few times to loosen and redistribute the toner powder.  The toner can become compacted inside the cartridge.

 

Try to determine if the problem is occurring with just a particular color or if the problem is occurring across all the colors.

 

The imaging unit is a separate unit.  Streaking, lines, ghost images, and repeating image defects will be image unit related.

 

Not Fitting

 

Verify they have the right cartridges for their specific printer model.  Make sure the correct color is being installed into the correct color slot.  Check inside the printer for any obstructions.  Check the cartridge itself for physical damage.
