Print Quality Issues

 

Verify the ribbon cartridge is fully inserted and properly installed into the printer.  Check the ribbon slack.

 

The print head will eventually wear out after a certain period of usage, if print quality isn’t improved with new ribbon cartridges then the print head may have an issue.

 

If the ribbon cartridge is continuously printing lightly then the ribbon may be depleted and the cartridge needs replacing.

 

Not Fitting

 

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

 

Make sure the cartridge is being installed in the correct orientation.  Using the instructions outlined above, verify the installation of the cartridge.

 

Check inside the printer for any obstructions.  Check the cartridge itself for physical damage.
