THIS ISN’T AN INK CARTRIDGE.  INSTEAD, IT’S A RIBBON CARTRIDGE.  THE PRINT HEAD IS SEPARATE FROM THE CARTRIDGE AND DOESN’T NEED MAINTENANCE.

Not Recognizing

 

Verify you have the correct cartridge for your specific model mail machine.

 

There is no smart chip on this cartridge.  Instead, once the ribbon hits a certain point it will trip an actuator in the machine that will give the low ribbon message.

 

Make sure that the cartridge is installed correctly and it is fully inserted.

It may also be necessary to tighten the slack on the ribbon itself.  If the ribbon looks loose on the cartridge you can tighten it by turning the winder on the cartridge.
