AR-350/450 BASIC PAPER FEED SECTION 2-4

Paper remaining quantity detection is common in each tray except for the manual feed tray. Remaining quantity is indicated in 3 steps plus paper empty
(4 steps in total).

Paper remaining quantity is detected by the number of times of changing of the remaining quantity sensor from when the tray starts lifting up to when

the upper limit sensor turns on. 

Remaining quantity sensor status change when the tray is moving up and remaining quantity

AR-350/450 BASIC PAPER TRANSPORT PATH AND PAPER EXIT 3-2

1) Paper transported from the fusing section is sent to the paper exit section of the machine. 
2) When the male bin stacker (AR-MS1) or the finisher (AR-FN5) is installed, the paper entry gate solenoid (FGS) selects the paper entry gate to

discharge paper outside the machine. 

3) The paper exit sensor (POD2) detects the rear edge of paper, and the paper exit motor (DCBM) is rotated reversely.

4) Paper is taken into the machine again, passed over the reverse gate, and transported to the duplex unit. 

5) When duplex printing is made, the ADU gate solenoid switches to the upper side of the ADU paper exit gate to switch the paper path to the ADU.

6) When paper is discharged to the left tray or when paper is transported to the console finisher (AR-FN7), the ADU gate solenoid switches to the

upper side of the ADU paper exit gate to switch the paper path to the ADU. 

The transport speed may be doubled in duplex printing depending on the paper position.
The positions of double speed are as follows:

1) From when the rear edge of paper passes the fusing section to when switchback operation is started.

2) From switchback operation, after the lead edge of paper passes APPD1, until a certain amount is transported.
3) After that, paper is stopped at the ADU paper feed position, and fed to the laser printer again.

The AR-FN6 is provided with the decurler to improve alignment capability of finishing.

The decurler makes decurling against curling of paper by means of the difference in rigidity of the upper roller (metal) and the lower roller (sponge).
