CHAPTER 5: MULTI-TRAY PAPER FEED SECTION
7. Vertical Transfer Unit Nip Pressure Adjustment
Check and adjustment procedure
Following adjustment is necessary if paper keeps jamming in the vertical transport unit due to lack of the nip
pressure at the paper feed roller 4.
(1) Rotate the roller nip pressure adjustment lever to UP to increase the roller nip pressure.
The lever can be adjusted in 5-steps, from 1 to 5. Step 1 is the weakest nip pressure and this is where the lever
is rotated to the most BOTTOM position. The standard position for the lever is the Horizontal position, which
is nip pressure No.3. (The photograph below shows the lever set to No.3 position).
The nip pressure of the roller changes from 87%, 93%, 100%, 107%, 113%, starting from the weakest No.1
position to the strongest No.5 position. The center (standard) No.3 position is 100%.
The levers on the right and left must be set to the same pressure position, or the paper will skew during the
paper feeding action due to the difference in the roller nip pressure on the right and left.
