Multifeeds, Misfeeds, and Paper Jams in Trays 6–9
Problem
Multifeed or misfeed paper jams occur in Tray 6, 7, 8, or 9.
Solutions
1. Change the Adjust Air Assist Values setting:
• Use this feature to adjust the amount of air volume generated by the tray blowers which assist in separating sheets when feeding paper. When using light-weight or heavy-weight paper, which stick together easily, select a stronger air flow setting in order to better separate sheets and prevent paper jams or multifeeds.
• This feature can be found in > > > . Select the desired > > > .
• The settings available for this feature are:
▪ System Default: The air volume is set to the appropriate amount based on the Stock and environmental conditions.
▪ Multifeed Support Table: Select this option if you use paper that tends to trigger multifeeds. This setting increases the air volume to a level higher than System Default.
▪ Mis-Feed Support Table: Select this option if you use paper that tends to trigger paper jams. This setting increases the air volume to a level higher than Multifeed Support Table.
▪ Forced Off: Select this option when working with special media that tends to jam as a result of the air flow that is introduced by Adjust Air Assist Values. This setting turns off Adjust Air Assist Values.
2. Change the Tray Heater setting.
• Use this feature to Enable (checked) or Disable (unchecked) the tray heater. The tray heater warms the air that is blown into the tray by Adjust Air Assist Values to help prevent paper jams and multifeeds by loosening contact between sheets.
• The tray heater may partially dry paper and affect print quality. If print quality is affected by dry paper, Disable the tray heater.
Note: Disabling the tray heater may result in an increase of multifeeds.
• This feature can be found in > > > . Select the desired > > > .
• To Disable (unchecked) the tray heater:
a. Remove any paper loaded in the tray.
b. In Adjust Air Assist Values select any option except Forced Off .
c. Disable (unchecked ) the tray heater and register the stock.
The printer performs a forced exhaust action for approximately one minute. During the forced exhaust action, do not change any settings or open a tray.
Important:
A forced exhaust with paper loaded in tray can lead to image quality problems.
d. After the forced exhaust is complete, load paper in tray.
3. Change the Multifeed Detection setting.
• Use this feature to Enable (checked) or Disable (unchecked) multifeed notifications; this feature does not make any other adjustments.
• The Multifeed Detection feature is accessed from > > > . Select the desired > > > .
• The settings available for the Multifeed Detection option include:
▪ Enabled (checked): Multifeed notifications are switched On.
▪ Disabled (unchecked): Multifeed notifications are switched Off.
Note: To prevent the system from reporting faults due to multifeeds, temporarily disable notifications. This allows the user to continue their workflow until the cause of the problem is resolved. Be aware that disabling this feature has no impact on the occurrence rate of actual multifeeds and, if disabled, multifeed sheets may cause jams elsewhere in the system and/or result in additional blank sheets in the final output.
