[Changing the Printer Ribbon Cartridge]
The ER-5100II receipt/journal printer uses a replaceable ink ribbon cartridge.
Once print becomes faint, a new ink ribbon must be installed.
To replace the ink ribbon, follow these steps:
1. Remove the printer cover and locate the ink ribbon cartridge. Grasp the tab in the center of the ribbon
cartridge and lift it carefully to remove.
2. Insert the new ink ribbon cartridge and press firmly into place. Remove any slack in the ribbon by
rotating the cartridge knob clockwise.
