The IPTU detects the following jams: ● Delivery-delay jam 1 This jam occurs if the IPTU media-feed sensor 1 does not detect the leading edge of a sheet of paper within a specified period from when the paper is delivered from the printer into the IPTU. ● Delivery-delay jam 2 This jam occurs if the IPTU media-feed sensor 2 does not detect the leading edge of a sheet of paper within a specified period from when the IPTU media-feed sensor 1 detects the leading edge. This jam also occurs if the IPTU media-feed sensor 3 does not detect the leading edge of the sheet within a specified period from when the IPTU media-feed sensor 2 detects the leading edge. ● Delivery-stationary jam 1 This jam occurs if the IPTU media-feed sensor 1 does not detect the trailing edge of sheet of paper within a specified period from when it detects the leading edge. This jam also occurs if the IPTU media-feed sensor 2 does not detect the trailing edge of a sheet of paper within a specified period from when it detects the leading edge. This also occurs if the IPTU media-feed sensor 3 does not detect the trailing edge of a sheet of paper within a specified period from when it detects the leading edge. 3-bin stapler/stacker Basic operation The stapler/stacker delivers jobs from the product several ways. The modes of delivery include simple stacking, job offset, and stapling. The stacker controller PCA controls all operations involved in these modes, according to the commands from the product. Figure 8-4 Basic operation of the stapler/stacker Output bin drive system Output bin drive system Control system Swing guide drive system Alignment drive system Stapler drive system Delivery drive system Feeder drive system Shutter drive system NOTE: With job offset, each sheet of a job is shifted to one side in the output bin in order to keep each sheet separate from the others.
