Stacker forms jam

Intervention Error Code
Stacker Forms Jam 0161 or 0164

If this error occurs shortly after you use the auto load function, you may be loading forms with the wrong first-fold direction. This causes the forms to fold opposite their original fold direction in the stacker. See step 6 or step 7 under Loading forms--auto load (dual simplex mode).

To clear the jam message from the printer operator panel and the touchscreen, you must open and close the stacker gate, or you must lower and then raise the stacker table.

These errors are not set when a Postprocessing Device Interface feature is installed and enabled.
  1. Visually check to see if a forms jam is actually present.
  2. Open the stacker gate.
  3. If you do not find a jam, clean the stacker jam sensors. See Cleaning the printer.
  4. If you find a jam, clear forms from the Stacker and Pendulum area.

    When you remove the forms from the stacker, leave 4 to 5 pages attached to the end of the job running in the stacker. This ensures correct forms folding when printing resumes.
  5. Close the stacker gate.
  6. If either stacker jam message is still displayed, press Check Reset on the operator panel of the affected printer or select OK on the touchscreen.
  7. Check for and resolve or postpone any other error or intervention message that appears on the printer operator panel or the touchscreen window.
  8. If necessary, enter the Align Forms procedure (see Forms are broken between the printers).
    1. Select Forms Feed twice. This provides enough forms beyond Printer 1 to auto load Printer 2.
    2. Complete the Align Forms procedure by adding enough forms beyond Printer 2 to splice (on the floor between Printer 2 and a postprocessing device) the forms just auto loaded on Printer 2 to the forms remaining threaded in a postprocessing device. Use the splicing procedures found in Splicing forms on the Infoprint 4000.
    3. Do all the steps in Checking forms alignment on both Printer 1 and Printer 2.
  9. Ensure that Forms Set on the printer control panel displays the same fold direction as the fold on the lower tractors.
  10. Select Start on the printer operator panel or on the Main touchscreen panel for the affected printer.
    <85>For printers with microcode levels, version 11.6.128 and higher, both printers and attached pre and postprocessing equipment can be started from the main panel of the printer console and the printer operator panels. Visually assure that no other personnel are working on the system before starting the system.
