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 Machine Status→Tools→Setup & Adjustment→Custom Paper
Settings. Select the desired Custom Paper→Change Settings→Adjust Air Assist
Values→Change Settings.
• 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 Machine Status→Tools→Setup & Adjustment→Custom Paper
Settings. Select the desired Custom Paper→Change Settings→Tray Heater→Change
Settings.
