PRINTER UNIT

Before unmounting the printer unit first disconnect the flat cable as explained in Step 1 of the section

“Keypad Unit”.

On the inside release the two retainers then push them so as to separate the cover and cutter from the

main unit.

Unscrew the two fixing screws paying attention to the earth wire, then remove the flat cable from the

slot and extract the printer unit.

If the paper feeder roller is worn, applying slight pressure on one side and then on the other, remove it

from the housing and proceed to replace it.
