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.

The CE390X is the high capacity version of the CE390A toner cartridge.  The 90X is physically larger than the 90A.

NOTE:  The CE390X will not work with the HP M601 series printers.  It is important to verify that the customer has the correct toner cartridge for their specific printer model.  Not all the printers that use the CE390A can use the CE390X.

 

Not Recognizing

 

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

 

There’s a smart chip located on the front of the toner cartridge which has two gold connection points.  Make sure the chip is clean and undamaged.  You can use a dry, clean, lint-free cloth to clean the connections.

 

Ensure that the toner cartridge is properly installed and fully inserted.

 

To remove and install the toner cartridge into the Laserjet M4555 series printers do the following;

NOTE:  The procedure is similar for other printers that use these toner cartridges.  For specific instructions for a particular printer model please refer to the User’s Guide for that printer available on HP’s website.

–          Pull the top cover release lever to open the top cover.

 

–          Grasp the handle of the print cartridge and pull it out to remove.

 

–          Align the print cartridge with its slot and insert the print cartridge until it clicks into place.

 

–          Close the top cover.

 

Print Quality Issues

 

There is a pull tape seal on the side of the cartridge that must be removed prior to installation.  It is important that this seal is completely removed.  If the cartridge is printing blank pages or after 2-3 pages it is now printing blank then the pull tape seal has not been removed or has broken off inside the cartridge while being removed

 

The OPC drum is located on the bottom of the cartridge covered by a spring loaded plastic shutter.  Lift the shutter up to view the drum.  Do NOT touch the OPC drum.  You can use a clean, dry, lint-free cloth 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.

 

Holding the cartridge by its ends, gently rock the cartridge back and forth a few times to redistribute the toner inside the cartridge.

 

Not Fitting

 

It is very important to verify you have the correct cartridge for your specific printer model.  The CE390X will not fit into all the printers the CE390A works with.  Make sure the cartridge is being installed in the correct direction.  Check inside the printer for any obstructions that may be interfering with the installation of the toner cartridge.  Check the toner cartridge itself for physical damage.  Verify that the pull tape seal has been removed from the side of the cartridge.
