PFU Air Assist Adjustment

There are air nozzles on the apical part of the feeder and the side guides of each tray in Paper Feed Unit PF-707m or Paper Feed Unit PF-711. Air blown from the nozzles makes feeding go smoothly by handling papers.

Depending on the paper type, smooth feeding may be difficult, and it may cause a paper jam. In this case, manually change the air assist settings. You can manually adjust the settings while checking the condition of air blow in the tray by shining a light from the air nozzle confirmation window of the tray.
