THESE ARE TONERS THAT HAVE THE OPC DRUMS BUILT INTO THE CARTRIDGES THEMSELVES AND EACH CARTRIDGE IS REPLACED AS ONE WHOLE UNIT.  THERE IS NO SEPARATE DRUM UNIT.

 

Not Recognizing

 

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

 

There’s a smart chip located on the left side of the cartridge.  Check the chip for damage or debris.  A Q-tip or a clean, dry, lint-free cloth can be used to gently clean the 2 gold contacts.

 

Make sure that the cartridge is installed correctly and is fully inserted into the printer.  Also check to make sure that the correct color is being installed into the correct color slot.  The cartridge should click into place.

 

To remove and install these toners into a HP CP4525DN printer do the following;

–          Open the front door.  Make sure that the door is completely open.

 

–          Grasp the handle of the color cartridge being replaced and pull it out to remove.  Make note of the locations of each color.

 

–          Make sure you have the correct color cartridge for the color being replaced.  Align the print cartridge with its slot and insert the print cartridge at an angle until it clicks into place.

 

–          Close the front cover.

Print Quality Issues

 

There is an orange plastic cover that must be removed prior to installation.

There is also a pull tape seal on the side of the cartridge that must be removed prior to installation.  It is important that this pull tape seal is fully removed.  If the cartridge is printing blank pages then the pull tape seal has probably not been removed or broke off inside the cartridge when it was pulled.

 

There are built-in print quality troubleshooting pages in the printer that can be used to help diagnose and solve print quality problems.  To access these print quality troubleshooting pages do the following;

–          Press the Home button.

–          Press the ▼ button to highlight the DIAGNOSTICS menu, and then press the OK button.

–          Press the ▼ button to highlight the PQ TROUBLESHOOTING setting, and then press the OK button to print the pages.

–          The printer returns to the READY state after printing the print-quality troubleshooting pages.  Follow the instructions on the pages that print out.

 

If the colors are not aligning properly then the printer may need to be calibrated.  This will NOT fix issues such as lines, streaking, faded print, or ghost imaging.  Calibration will only fix the colors not overlaying properly.  To run the calibration do the following;

–          Press the Home button.

–          Press the ▼ button to highlight the CONFIGURE DEVICE menu, and press the OK button.

–          Press the ▼ button to highlight the PRINT QUALITY menu, and then press the OK button.

–          Press the ▼ button to highlight the FULL CALIBRATE NOW setting, and then press the OK button.

 

The OPC drum is located on the front of the cartridge.  Visually inspect the OPC drum for damage or debris.  Do NOT touch the OPC drum.  A soft, dry, lint-free, clean, cloth can be used to gently wipe the OPC drum.  Do NOT use moisture of any kind.

 

Not Fitting

 

Make sure they have the correct cartridges for their specific printer model.  Verify the correct color cartridge is being installed into the correct slot.  Make sure the protective cover and pull tape seal have been removed.  Check inside the printer for any obstructions.  Check the cartridge itself for physical damage.
