Adjusting the Upper Limit Position (A3 LCIT)
Effect of Adjusting the Upper Limit Position
Adjusting the upper limit position lowers the upper limit position. (for dealing with repeated feeding problems due to double feeding or double feeding as a bundle)
During paper feeding, this achieves the effect of fanning the paper by abutting it against the paper tray plate for pre-separation (bank).Adjusting the upper limit position raises the upper limit position. (for dealing with repeated failure to feed)
During paper feeding, this achieves the effect of reducing transport resistance by reducing paper abutting against the paper tray plate for pre-separation (bank).
Be careful as raising the upper limit position tends to make the unit prone to multi-feeding.
Open the front cover.
Remove the inner covers.
When removing the 1st or 2nd paper feed unit, lower the lever [A] and remove the inner upper cover [B] (
x3, knob x1).
When removing the 3rd paper feed unit, remove the inner lower cover [A] (
Pull out the relevant paper tray.
Pull out the paper feed unit [A] (
Remove the stopper bracket [A] and then remove the paper feed unit [B] (
Adjust with the screw that holds the paper lift sensor bracket.
[For repeated feeding problems due to double feeding or double feeding as a bundle]
Position the paper lift sensor bracket so it increases the gap [C] between the stay [A] and the paper lift sensor bracket [B] while keeping an eye on the scale on the upper part of the stay (1mm between lines).
Positioning it at a point at a distance of 0.5mm from the position before adjustment lowers the upper limit position about 0.8mm below the current state.
[When repeatedly fails to feed]
Position the paper lift sensor bracket [B] so it reduces the gap [C] on the stay [A] while keeping an eye on the scale on the upper part of the stay (1mm between lines).
Positioning it at a point at a distance of 0.5mm from the position before adjustment raises the upper limit position about 0.8mm above the current state.
If there is no improvement by adjusting the stay position, this adjustment is not effective. Put back the stay to the original position along with the marking [A].
