Confirmation Tasks
Check an operation of the Duplex solenoid with Motor & Clutch
of the Self-diagnostic Mode.
Confirm that an operation of the gate with Motor & Clutch of the
Self-diagnostic Mode with eyes (EXIT SOLENOID), whether the
operation is smooth or the opening and closing is proper.
Confirm that a timing of opening the separator DUP is appropriate
through test print under the condition that cover is open.
By touching, confirm whether a Dup-IN sensor lever is smooth,
opening a rear cover.
Confirm a sensor signal is correctly detected by the SWITCH
SCAN function of the Self-diagnostic Mode.
Confirm that there is no obstacle such as paper piece and burr.
Check an operation of Duplex motor with Motor& Clutch of the
Self-diagnostic Mode.
Confirm with rotation of the roller opening the rear cover.
Confirm that retracting/reversal roller of the Duplex unit touches
a pinch roller of the cover when a rear cover of the Duplex unit
is closed. (a pinch roller is rotating while the roller is rotating.)
Confirmation Tasks
By touching, confirm whether a Dup-IN sensor lever is smooth,
opening a rear cover.
Confirm a sensor signal is correctly detected by the SWITCH
SCAN function of the Self-diagnostic Mode.
Check that paper is in reverse from a slit of the rear cover with
eyes.
Confirm that a planet gear in the Duplex unit operates smoothly
when reversal operation is not implemented.
