41. Check the operation of “Frame, Assembly, Middle, Right” by the following
procedure.
WARNING
In case of gear train on the “Frame Assembly,
Middle, Right”, if you try to check its operation
forcibly by hand at completing procedures on the
previous pages, arranged phase will be
dislocated, since “ASF Unit” is not fixed steady to
the mechanism. Therefore, check its operation by
the following procedure.
Step.A Rotate “Gear,35.4” about 5
°
(5 degree) right direction,
pressing “Lever, Stopper, ASF” toward green arrow direction.
(Gear will be heavy and it won’t be able to rotate just by
“Gear,35.4”) (Refer to Figure4-123)
Step.B Take your hand off from “Lever, Stopper, ASF”, and rotate
“Gear,35.4” as soon as rotate “Roller, Paper Feed” on the
“ASF Unit” toward yellow direction slowly.
(Refer to Figure4-123)
Step.C. At the point that “Roller, Paper Feed” changes from “Stand-by
Position” to “Hopper Position”, take your hand off from
“Roller, Paper Feed” (the hand which was rotating “Roller,
Paper Feed”), and make sure that “Gear,35.4” slips when
only “Gear,35.4” is rotated right direction.
(Refer to Figure4-122)
Step.D Rotate only “Gear,35.4” to right direction one round, pressing
“Lever, Stopper, ASF” toward green arrow direction again.
(It is all right to take your hand off from “Lever, Stopper,
ASF”, if “Gear, 35.4” starts rotating with duty.)
(Refer to Figure4-123)
Step.E Make sure that paper return lever pops out toward front as
soon as “Roller, Paper Feed” returns to “Sand-by position”.
