2.3 PAPER SIZE DETECTION 
 
There are four paper size switches [A] worki ng in combination. Switch 1 (right end) is for 
tray set detection. The other three switches  detect the paper size as shown in the table 
below. The actuator [B] is  moved by the end plate [C].

For non-standard paper sizes, if they are not visible on the user tool screen for selecting 
paper sizes, then set SP 5-112 to 1. If the us er selects one of these sizes, auto paper size 
selection is disabled. 
 
2.4  REVERSE ROLLER AND PI CK-UP ROLLER RELEASE 
 
The pick-up roller and separation roller release  the paper when it is not being fed. This 
helps remove jammed paper easily.

2.5 PAPER LIFT 
 
When the machine detects that a tray has been  placed in the machine, the tray lift motor 
[A] rotates and the coupling gear [B] on the tray lift motor engages the pin [C] on the lift 
arm shaft [D]. Then the tray lift arm lifts the  tray bottom plate [E] until the paper lift sensor 
for the tray detects that the top of t he stack is at the paper feed position. 
When the tray is removed from the machi ne, the connection between the...

2.6 PAPER HEIGHT AND END DETECTION 
2.6.1  PAPER HEIGHT DETECTION 
 
Two paper height sensors [A] [B ] and actuator [C] are built into the paper tray lift motor. 
The paper height sensors, detect  the amount of paper in the tray. 
The actuator [C] has two semicircles, and it is engaged with the lift arm shaft via gears. 
The paper height sensors det ect the paper size depending  on the position of the two 
semicircles. The list shown below shows the detection...

2.6.2 PAPER END AN D BOTTOM PLATE 
 
The paper stack raises the paper end feeler  [A] and the paper end sensor [B] deactivates 
if there is some paper in the paper tray. 
When the paper tray runs out of paper, the paper  end feeler [A] drops into the cutout in the 
tray bottom plate. At this time  the paper end sensor [B] activates
