How to Replace Cartridge(s)

It might be time to replace the ink ribbon of your Epson TM-300C printer when there are already print errors in your receipts. Here's how you do it:

  1. Open the printer cover. Remove the used ink ribbon cartridge by grasping its tab on the left side and lifting the left side out the cartridge first.
  2. Take the new ink ribbon cartridge out of its protective bag. In a clockwise direction, turn the ribbon-tightening knob in the cartridge to take up any slack in the ribbon.
  3. Fit the ribbon between the ribbon mask and head unit, then push the ink ribbon cartridge firmly into position.
  4. Turn the ribbon-tightening knob clockwise up to five or six times. This feeds the ribbon smoothly into place between the ribbon mask and head unit. Confirm that the ribbon is not creased or twisted in any way.
  5. Close the printer cover.
