6. EXIT ROLLER DRIVE
6.1 ROLLER DRIVE MECHANISM
[F]
[G]
The exit rollers [A] take over paper transport from the copier. When the copy
paper actuates the copier exit sensor, the exit rollers start rotating. The exit
rollers continue to rotate for 250 milliseconds after the copy paper has gone
through the paper sensor [B].
The roller drive motor [C] rotates the lower exit roller via the roller drive belt
[D]. The shaft of the lower exit roller is a cylindrical cavity type which rotates
around the transfer wheel shaft [E]. The paper sensor is positioned just in
front of the exit rollers. The paper sensor detects misfeeds in the sorter.
