When you requires printing with the top cover open, the interlock switch and the cover open sensor
must be bypassed. Because these sensors automatically disable the printing operation when the top
cover is taken off.
To bypass the interlock switch, remove the top cover, and close the left top cover hinge.
To bypass the cover-open sensor, remove the left side cover, disconnect the cable from connector CN9
on the MAIN board, and jumper pins 2 and 3 of CN9.
