the LF motor (4).
Carrier drive:
1) Remove the chassis frame. (Refer to 5.3 "Chassis Frame and Platen".)
2) Remove the screw (8) holding the belt clamp (9) from the hole in the center frame (7-A).
3) Remove the left and right carrier stoppers (10). Remove the main shaft bracket screw (11) and

5) Remove the carrier motor spring (14).
6) Remove the carrier motor bracket screw (15).
7) Remove the two screws (18) holding the carrier motor (16) to the motor bracket (17), and then
remove the carrier motor (16).

Only Original version (Control PCB:Artwork No. 999-32300):
12) Remove the two screws (28) holding the left and right FG wires (29).
Note:
By change for double-sides PCB (2nd version control PCB:Artwork No. 999-35810), the FG
wires (29) was eliminated by the carrier guide rail (33).
13) Unless it is necessary to readjust the adjustment screw (30) and nut (31), do not loosen or
remove them. In addition, do not remove the nut (32) attaching the side frame to the center
frame.
When removing the carrier without removing the platen, it is possible to remove the carrier
guide rail (33) and then remove the carrier from the frame (7) by following the procedure
described in steps 2 through 4 above. Remove the two screws (34) from the carrier guide rail
