Next time a job occurs, the paper is forcibly stopped at the stop position (leading edge) shown in the figure for troubleshooting.
When checking the image on the ITB, set PRINTER=99. (Refer to "How to Use" shown below.)
When the paper is forcibly stopped, a jam code "AAxx" is displayed.
When the paper is forcibly stopped, when a normal jam occurs or the paper is normally delivered, the PRINTER setting is
automatically cleared.

Use case
• When bent paper, skew, or wrinkles occur
• When jams occur frequently
• When you want to check the image on the ITB
Caution
• Remove the stopped paper by the normal jam removal procedure. After the paper is removed, the job will be automatically
recovered.
• Since the Primary Transfer Roller is not disengaged when a jam has occurred, be sure to remove the ITB Unit/Drum Unit
after manually disengaging the Primary Transfer Roller (refer to the Service Manual for the procedure).
• If a normal jam cord is displayed, the paper is jammed at a position other than the specified position.
• When a job in which the paper does not pass the specified stop position is executed, the setting to forcibly stop the paper
becomes disabled.
• Unfixed toner may be attached depending on the stop position. Handle it carefully.
