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 you have the correct cartridge for your specific printer model.

 

This cartridge is used in a very old HP printer.  There is no smart chip on this cartridge so it’s key that the cartridge is installed correctly into the printer and is fully inserted.  The printer will not give a warning when the toner is low.  Instead, HP recommends replacing the toner cartridge if the cartridge is printing lightly or poorly and shaking doesn’t improve the quality.

You can also try resetting the printer by turning the printer off, disconnecting the power cord for 10-15 seconds, plugging the printer back on, and turning the printer on.

 

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 pull tape seal is completely removed.  If the cartridge is printing blank pages then the pull tape seal probably hasn’t been removed or it broke off inside the cartridge while being removed.

 

Rock the cartridge slowly from end to end 5 times to distribute the toner powder inside the cartridge.
