简介

Direct access to the print mechanism is limited, whether you need to investigate a fault or clear a particularly severe paper jam. Removal of the scanner unit makes it much easier, and is a prerequisite to further disassembly.

Ribbon cables are all of the push fit type. Pull gently but firmly to disengage from the socket. To reconnect, simply push the reinforced end of the ribbon firmly into the socket, making sure it's the correct way round.
