5.4 LF (Line Feed) Motor and Carrier Drive

 

 

Removal 

 

LF (line feed) motor: 

1) 

Remove the chassis frame and platen.    (Refer to 5.3 "Chassis Frame and Platen".)   

 
2) 

Remove the LF motor spring (1). 

 
3) 

Remove the LF middle gear (2). 

 
4) 

Remove the LF motor plate screw (3).   

 
5) 

Remove the two screws (6) holding the LF motor (4) to the LF motor plate (5) and then remove 
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 
then remove the main shaft bracket (12).    Pull the main shaft (13) out of the hole in the side 
frame (7-B). 

 
4) 

The carrier can now be removed from the frame (7). 

 
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). 

 
8) 

Remove the belt tension spring (19). 

 
9) 

Remove the screw (20), and then remove the idle pulley bracket assembly (21). 

 
10)  Remove the E-ring (22) and then remove the idle pulley (23). 
 
11)  Pull the drive pulley shaft (24) out from the back of the frame (7); the drive pulley (25), drive 

pulley cap (26), and the drive belt (27) can now be removed. 

 
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 
(33).
