This sensor carries out control of operating and stopping of the CR motor and PF motor
drive circuits via the MAIN board's logic circuit after detecting the cover's status. This
control is the same when the paper support level is in the release state.
CIRCUIT BOARD PLACEMENT
The panel unit is located i the right front of the printer and the AC inlet, power supply
circuit board and the MAIN circuit board are mounted in the compartment on the
printer's rear side.
