To ensure paper stacking amount which can satisfy specifications, adjust the stopping position (motor drive range) of
the paper feed tray during automatic up/down.
Perform adjustments as follows without the paper feed tray automatic up/down drive gear of section “2-2-5” secured.
q
Move the switch bracket for the length of the long
hole and adjust so that when the up/down lever is

lower limit detection microswitch turns ON the switch,
and a clearance of 0.7
±
0.1 mm (0.028"
±
0.004") is
formed at the position shown in the figure.
