NOTE:
Horizontal movement of the left tractor is restricted by a stopper on the lower cover.

2. Remove the tractor drive shaft locking clamp.
3. Open the claw (1), and remove the drive gear (2) from the groove (3) of the drive shaft (4).
4. Release the right groove (5) of the drive shaft from the guide (6) of the main frame.
5. Shift the groove in the direction of Arrows A and B. This releases the left part of the drive shaft from the
guide hole (7) of the main frame.
6. Push the left part of lock shaft (8), and move the groove (9) in the direction of Arrow C to release the
groove from the hole (10) in the main frame.
7. Shift the lock shaft (8) to the right, and move the shaft in the direction of Arrow D to remove the shaft
from the larger guide hole (11).
8. Push the left part of the tractor assembly in the direction of Arrow E, and remove the tractor assembly
(12) while pulling the drive shaft in the direction Arrow F. This moves the shaft out of the guide holes (13
and 14) of the printer frame.

from the two shafts (4) and (8).
NOTES:
Marks A (18) and B (19) of the left (20) and right pin tractors (21) must be aligned when installed.
Install the left pin tractor assembly to the left of the stopper on the lower cover. This limits movement and
correctly positions the paper against the paper end sensor.
