SOLENOIDS
SOL1
Pick up Solenoid
- Tray 2
Switches on when the tray 2 (middle tray) lift motor switches
on. This solenoid lowers the pick–up roller of tray 3.
SOL2 Separation Roller
Solenoid - Tray 2 When tray 2 (middle tray) is selected as the paper source,
this solenoid energizes and brings the separation roller in
contact with the feed roller until the leading edge of the sheet
feeds to the paper feed sensor.
SOL3
Pick up Solenoid
- Tray 3
Switches on when the tray 3 (bottom tray) lift motor switches
on. This solenoid lowers the pick–up roller of tray 3.
SOL4 Separation Roller
Solenoid - Tray 3 When tray 3 (bottom tray) is selected as the paper source,
this solenoid energizes and brings the separation roller in
contact with the feed roller until the leading edge of the sheet
feeds to the paper feed sensor.
SOL5
Pick up Solenoid -
Tray 1
Switches on when the tray 1 (tandem tray) lift motor switches
on. This solenoid lowers the pick–up roller of tray 1.
SOL6 Separation Roller
Solenoid - Tray 1 When tray 1 (tandem tray) is selected as the paper source,
this solenoid energizes and brings the separation roller in
contact with the feed roller until the leading edge of the sheet
feeds to the paper feed sensor.
SOL7 Front Side Fence
Solenoid -Tray 1 When the right tray paper sensor in the tandem tray signals
paper out, and the left tray paper sensor signals paper
present, this energizes this solenoid which pulls open the
front side fence until the front side fence open sensor detects
the actuator of the front side fence and switches off the
solenoid, leaving it locked in the open position, to allow the
rear fence to push the paper stack from the left tray into the
right tray.
SOL8 Rear Side Fence
Solenoid - Tray 1 When the right tray paper sensor in the tandem tray signals
paper out, and the left tray paper sensor signals paper
present, this energizes this solenoid which pulls open the
rear side fence until the rear side fence open sensor detects
the actuator of the rear side fence and switches off the
solenoid, leaving it locked in the open position, to allow rear
fence to push the paper stack from the left tray into the right
tray.
SOL9 Right Tray Lock
Solenoid - Tray 1 Releases the lock lever when the left tray paper sensor in the
tandem tray signals that there is no paper in the left tray .
SOL10 Left Tray Lock
Solenoid - Tray 1 When the rear fence motor in the tandem tray switches on,
this energizes the left tray lock solenoid. This locks the left
tray so it does not move while the rear fence pushes the
stack from the left tray to the right tray.
SOL11 Duplex Junction
Gate Solenoid Controls the opening and closing of the duplex junction gate
at the mouth of the inverter unit.
SOL12 Positioning Roller
Solenoid After a sheet has been aligned by the fences of the duplex
unit, this solenoid energizes and pushes down the positioning
roller (a sponge roller).
SOL13
Guide Plate
Solenoid Energizes when a jam occurs between the vertical transport
rollers and registration roller to force the guide plate open
and divert paper fed from below into the duplex tray.
SOL14 Inverter Junction
Gate Solenoid Operates the inverter junction gate. The inverter injunction
gate turns paper into the path to the inverter unit below where
it is 1) inverted for face
down output or 2) inverted for 2nd
side printing.
