Installing the Ribbon Cartridge
In order to avoid damaging the print head or mechanical gearings, this printer
accepts only original Compuprint ribbon cartridges.
Therefore, if you install a not original cartridge, the printer may not work.
1. Remove the cartridge from its bag.
2. Unhook the green ribbon mask from the cartridge
pins.
3.
Open the printer cover.
The print head will automatically move in the middle
of the printer.
