Compile Tray Operation With Multiple Paper Sizes; Tamping; Front Tamping - Oki B930 Service Manual

When feeding large paper in the non-staple mode, there may be a misalignment depending on
paper characteristics. For this reason, the default paper capacity is set to a smaller value.
Compile Tray Paper Capacity
For small paper (less than 216 mm in the feed direction)
For large paper (216 mm or more in the feed direction)

Compile Tray Operation with Multiple Paper Sizes

When two or more paper sizes are used and their widths are same (example: A4L and A3S), all
the sheets are compiled and stapled as a set on the Compile Tray, and then ejected to the
Stacker Tray.
While if two or more paper sizes with different paper width are used, stapling paper on the Com-
pile Tray is stopped when a different size is detected. Such different-size sheets of paper are
forcibly ejected to the Stacker Tray.

Tamping

When paper is fed from the Puncher to the Compile Tray, tamping operation is performed to align
the paper in the paper width direction on the Compile Tray.
Tamping is an operation to align paper to the specified position on the Compile Tray using the
Front Tamper or Rear Tamper by moving them to the end of paper by the respective motors.
Tamping is executed each time when a sheet of paper reaches the Compile Tray. Additional
tamping is executed after tamping the last sheet.
There are three types of tamping.
