A661D500.wmf

[C]

[B] [A]

The DF has three width sensors (- 1 [A], - 2 [B], and - 3[C]) to detect the original width and two original length sensors (-1 [D] and -2 [E]) to detect the original length. The DF detects the original size through the combination of those five sensors as shown in the table on the next page.

When using an original of a non-standard size, the user needs to input the original length at the operation panel.

When the print key is pressed, the DF pick-up solenoid [A] turns on and the originals are lifted up to the pick-up roller [B] by the entrance guide [C]. At the same time, the DF feed clutch [D] turns on.

At 200 ms after this, the DF feed motor turns on. The original is fed to the paper feed belt [E] from the top page. The pages are separated by the separation roller [F] and the top sheet of the original is fed to the 1st transport roller [G]. The original separation system uses the FRR system.

[D]

A661D503.wmf

When the leading edge of the original reaches the registration sensor [A], the DF feed and transport motors turn off. After a short time the DF feed and transport motors turn on again. The original is fed to the DF exposure glass [B] and it is scanned in this area. The original is fed through to the 2nd transport roller [C] and fed out by the exit roller [D].

The DF feed motor speed while feeding the original to the registration sensor is 59.4 mm/s. However, when the motor turns on again to feed the original to the exposure glass, the speed depends on the selected reproduction ratio. At 100%, it is 90 mm/s.

1. When the leading edge of the original reaches the registration sensor [A] the DF feed and transport motors turn off. After a short time, the DF feed motor turns on and the DF transport motor turns on in reverse to drive the reverse table roller [B]. The original is fed to the DF exposure glass [C] and it is scanned in this area.

2. When the leading edge of the original reaches the exit sensor [D], the junction gate solenoid turns on and the junction gate [E] is opened. The original is transported to the reverse table [F] to reverse the original.

3. 33 mm after the trailing edge of the original reaches the exit sensor [D], the junction gate solenoid turns off and the junction gate [E] closes. At the same time, the DF feed and transport motors turn off.
