Replacing the Interface Board
Replacement Method
1. Remove the screws (2) that anchor the bracket of the interface
board then pull the interface board towards you. When you do
this, be careful not to perform any unreasonable operations that
will damage the connecting cable and do not pull the cable too
much. If you do, it will cause a malfunction.
Always turn off the power to the printer before replacing the interface
board. Do not pull it out with unnecessary force. This will cause an
accident.
