2.2 PAPER FEED
This products uses an FRR type paper feed mechanism.
The paper feed unit consists of the pick-up ro ller [A], paper feed roller [B], separation roller
[C], and relay rollers.
There is a torque limiter in the back of the separation roller (ferrite powder type).](http://img.usermanuals.tech/thumb/64/98663/w64_mp-c3000-service-manual-1509271621_d-1306.png "Page 1307

2.3 SEPARATION ROLLER AND PICK-UP ROLLER RELEASE
To prevent the paper from being torn when pu lling out the paper feed tray, the separation
and pick-up rollers release automatically.
When the paper tray [A] is not inside the machine, the separation roller [B] is away from
the paper feed roller [C], and the pick-up roller [D] stays in the upper position.
When the paper tray is set into the machine, it pushes the release lever [E]. This...](http://img.usermanuals.tech/thumb/64/98663/w64_mp-c3000-service-manual-1509271621_d-1307.png "Page 1308

2.4 TRAY LIFT
When the paper feed tray is pushed in the mach ine, the tray switch on the back turns on
and the tray lift motor [A] starts. The base plate lift shaft [B] is coupled to the lift motor at
the shaft [C], so the base plate [D] of the tray is lifted. After a short while, the top of the
paper stack contacts the pick-up roller and lifts it up. Then the motor st ops lifting the plate

2.6 PAPER END DETECTION (PAPER FEED SIDE)
The paper end sensor 1 [A] detects when copy paper in the paper feed side runs out.
When there is paper in the tray, the paper pus hes up the feeler [B] and the actuator enters
the sensor. When paper runs out, the feeler drop s in to cutout [C] and the actuator leaves
the sensor, and the machine detects t hat there is no paper in the tray.](http://img.usermanuals.tech/thumb/64/98663/w64_mp-c3000-service-manual-1509271621_d-1310.png "Page 1311

Paper Stack Transport

2.7 PAPER STACK TRANSPORT
When the paper in the paper feed side is us ed up, the tray motor [A] and stack transport
clutch [B] turn on. Then the end fence [C] moves the stack of paper from the paper
storage side to the paper feed side.

does not switch on, so drive from the tray motor only transfers to the relay roller
and not to the fence mechanism.

Then the end fence [C] moves the stack of paper from the paper storage side to the paper feed side. ƒ During paper feed, the stack transport clutch ( Electrical Component Layout) does not switch on, so drive from the tray motor only transfers to the relay roller and not to the fence mechanism. While the stack is in motion, it pushes the side fence [D] aside, and the side fence sensor [E] detects that the fence is open. After the stack has been moved all the way ac ross, a spring in the side fence moves the side fence back, and the side fence sensor detects that the fence is closed. Then, the tray motor reverses until end fence home position sensor [F] is deactivated.
