2. Check the range of the
up and down
movement of the
ejection rollers.
Check if the operating
position after feeding in
the first sheet is normal.
(1)If it moves askew (due to
the forward and backward
shift of phase on the eject
guide).
(2)If the range of motion is
too small.
Check if the gap between
the ejection roller and the
ejection pulleys is approxi-
mately 3.5 - 5.5 mm.
(Check gaps while making
paper still in the intermedi-
ate process tray.)
If the gap is not correct, fix balance of the bundle
eject unit.
If (1): Correct the phase shifting with meshing of the
front and back gears.
(Turn on U240 - Motor-EjectUnlock (30) to check the
balance of the front and back rollers with the bundle
eject unit opened.)
If (2): Adjust the positioning of or replace the Mount
PI Upper Guide.
3. Execute U240 Motor -
Width Test A3/LD to
adjust the position of
the width adjuster
cursor of the process
tray. Check if the cursor
is located at 0 - +0.5
from the paper edge.
Or check if the cursor is
abnormally shifted.
(The DF and the main
unit paper sources)
If the width adjuster cursor is wrongly positioned,
perform U246 Finisher - Width Front HP/Width Tail
HP.
