The knob can be used to open the paper transport path and clear jammed paper.
The paper transport path is provided with a unit comprising paper feed roller 4 and feed sensor 4 as well as two
nip release solenoids.
Paper feed roller 4 transmits the rotary force of the multi-feed tray pickup motor to transfer clutch 4.
In addition to transport completion and nip release operation, the vertical transfer unit has a paper feeding
operation to assist transport operations during printing.

When Tray No.1 is selected, and if the paper size detection sensor is detecting the paper (A3, B4, Ledger,
Legal size papers), and if the test mode No. 3941 [Assist transport] is selected to [Enable], the assist transport
operation becomes effective.
After the paper is transported to the Timing roller & Guide roller, and the buckle is made on the paper, the FL
multi feed tray pickup motor is rotated at the same speed as the print drum and transfer clutch 4 is engaged at
print durm angle 225.5 degrees to push the paper up. The transfer clutch 4 is disengaged when the print drum
rotates to 257.5 degrees to end the assist transport operation.
