PAPER FEED
B089/B093 2-54 SM
From paper near end to paper end
When paper is used up, the pressure on the bottom plate reduces, so the upward
pressure increases, causing the pressure of the feed roller against the top of the
stack to increase.
However, for small paper sizes, because of the previous correction (600 ms
reverse rotation of the lift motor), the pressure between the feed roller and the top
of the stack becomes too small at some point as paper is used up, and this could
cause paper feed problems. This condition is more significant for smaller paper
sizes, such as A5, as shown in the diagram.
If a paper feed problem occurs when the stack is partly used up, the pressure can
be re-adjusted (
" in the graph) using the following SP modes. The default is set for
50 sheets (at the near-end point)
The lift motor rotates forward for the time specified by the SP mode to increase the
pressure.
