2.9.7 FEED PRESSURE ADJUSTMENT FOR PAPER SIZE
Overview
For the friction pad system, the pressure from the top of the stack against the feed
rolleris very important for paper feed quality from the paper tray. If the pressure is
high, double feed may occur. On the other hand, if the pressure is low, non-feed
may occur. Because of this, the pressure must be varied depending on the paper
size, paper weight, and amount of paper remaining in the tray. To achieve this, the
pressure for each paper tray can be adjusted using SP mode.
Paper Size Thresholds
The upward pressure from the bottom plate spring is always the same. However,
downward pressure from the stack on the bottom plate depends on the paper size.
Because of this, for a smaller paper size, the pressure of the top of the stack
against the feed roller is more than normal (because of the smaller downward
pressure from the stack), so adjustment may be necessary.
Using the following SP modes, either two or three paper size ranges can be
specified. Using other SP modes (explained later), the pressure can be adjusted
separately for each of these ranges to deal with any feed problems that have been
occurring.

Paper Size Ranges
For Three Size Ranges
Small paper size range: Paper sizes equal to the ‘Small’ SP mode value, or
smaller.
Middle paper size range: Paper sizes greater than the small paper size, up to and
including the middle paper size specified by the ‘Middle’ SP mode.
Normal paper size range: Paper sizes greater than the ‘Middle’ SP mode.
For Two Size Ranges
Small paper size range: Paper sizes equal to the ‘Small’ SP mode value, or
smaller.
Normal paper size range: Paper sizes greater than the ‘Small’ SP mode.
