Date : Oct. 27, 1997
No. : ECR-1113
1. Model name:
ER-01PU (KA/KB/TQ)
2. General:
Due to a failure in molding process for housing, the housing pulley gears shaft may
break. To correct this problem, the stem of the gear shaft is reinforced. At the
same time, the corrective parts: S-Angles for reinforcement and S-Pins for
replacement are made available as repair parts.
3. Action:
((For the field))
<To correct field units>
(1) For the units without the shaft breakage: Reinforce the shaft by attaching an
S-Angle (reinforcing plate).
(2) For the units with the shaft breakage: Replace the shaft with an S-Pin and also
add an S-Angle.

(How to attach corrective parts)
(1) Before starting modification, put a screw(4) (XBPSD30P06KSO) into the
S-Pin(2) (LPINZ2321BHZZ).
(2) Remove burrs from the printer housing at broken part by rubbing with a
sanding paper to flat the surface.
(3) Insert the S-Pin(2) (LPINZ2321BHZZ) and the Screw(4) (XBPSD30P06KSO)
into the housing using a cross-bladed driver. Ensure to insert the S-Pin(2)
fully to its stem perpendicular to the housing surface.
(4) If screwdriver is turned in reverse direction, only Screw(4)
(XBPSD30P06KSO) comes off.
(5) Mount the pulley gear(7) and check if it rotates smoothly without any problem
with the pitch of both gears. After the check, apply grease to the S-Pin.
(6) Attach pulley gear(7), washer(8), and timing belt(9).
