Recovering from a forms jam

You must set the following basic configuration items (Printer Definition -> Printer -> PDL -> IPDS) to allow automatic reprinting after a forms jam recovery:

After some jams occur within the printer engine, the printer automatically reprints certain pages as part of its recovery process. This happens only if the printer is configured to allow reprinting.

Automatic reprinting reprints the number of pages, based on the current, in-effect page length. That includes all of the pages that can fit in the forms path between the transfer station in Printer 1 and the forms exit area in Printer 2 at the time the jam was detected.

If a postprocessing device is used, an extra number of pages can be added to the normal number of reprinted pages by setting the Jam Recovery Point Distance configuration item in the Printer - Setup window (Printer Definition -> Printer -> Setup) to a non-zero value. This extra number of pages is the configured distance from the forms exit area to or through the postprocessing device.

Figure 86 shows the normal reprint path length from the transfer station (Point A) in Printer 1 to the forms exit area in Printer 2 (Point B), and the additional Jam Recovery Point Distance from the forms exit area in Printer 2 (Point B) to or through the postprocessing device.

After the automatic reprinting of pages, you must check for and discard any duplicate pages that may have been printed. Locate the first reprinted page. Then attempt to find that same page in the forms exit area or the postprocessing device. If you find it, discard all duplicate pages.

In all cases but one, the automatic reprinting of pages recovers all pages that might have been lost or damaged as the result of the jam. The exception occurs when a Fuser Wrap error causes the jam. A jam of this type can back up (accordion-pleat) the forms until the error is detected and the forward movement of the forms is stopped. If this occurs, a few lost pages are not automatically reprinted. You need to work with the host system console operator to recover those lost pages.

If the printer is not configured to recover lost pages, you may need to ask the host system console operator to do one of the following:

You must re-thread the printer with the jam.

In addition to re-threading the printer with the jam, you may also have to re-thread the other printer (if the jam occurred in Printer 1). Whenever re-threading is required, the Align Forms window (Forms -> Align Forms) automatically appears on the touch panel. This requires you to execute and complete the "Align Forms" procedure.
