To repair the broken ribbon in the IDP Smart 70:
- Open the top cover and remove the ribbon cartridge.
- Pull the two broken ends together and reattach them with tape.
- Place the ribbon cartridge back into the printer.
Ribbon breakages occur from time to time, but if it keeps recurring then you should carry out a thorough clean of your printer, check your cards are not contaminated and that the colour density of the printer is not set too low or high. You can do this by adjusting the print head power.
