Auto Cutter Assembly - Ithaca 75 User Manual

Note: You may find it easier to remove the Transport Sensor and the Drive
Wheel Assembly (see the parts in the list below) before separating the
Right-Side Frame.
To remove the Transport Sensor (A) before separating the Right-Side
Frame (D), remove the Worm Wheel Gear (H, figure 14) to free the
Transport Sensor Cable. See the instructions under "Left-Side Frame."
The Drive Wheel Assembly consists of the following items shown best
in figure 14:
Drive Wheel Roller (R, figure 14)
Drive Wheel Shaft (S, figure 14)
Drive Wheel Bearings (Q, figure 14)
Three E-Clips (B, figure 14)
Brass Pin (K, figure 14)
To remove the Drive Wheel Assembly before separating the Right-Side
Frame (D), see the instructions under "Left-Side Frame."
Do the following steps to remove the Right-Side Frame (D) from the Transport-
Auto Cutter Assembly. Refer to figure 13 on the facing page and figure 14 on
the next page.
1. Remove the E-Clip (H) from the shaft of the Auto Cutter (A, figure 14).
2. Remove the two screws (J) holding the Right-Side Frame (D) to the Lower
Paper Chute (B) with a #0 Phillips screwdriver.
3. Remove the hex-head screw and lock washer (G) holding the Right-Side
Frame (D) to the Back Plate (D, figure 14) with a 7/32 inch nut driver.
Be sure that the lock washer stays with the screw. Replacing the Back Plate
(D, figure 14) without the lock washer may cause it to become loose and
damage the printer.
4. Remove the Right-Side Frame (D) by pulling it straight out from the rest of
the Transport-Auto Cutter Assembly.
Be careful not to lose the Cutter Spring (F) from the Shear Plate (E, figure
14). When reinstalling the Right-Side Frame (D), be sure to line up the
Drive Wheel Bearing (E) on the Drive Wheel Assembly (R, S, Q, B, K,
figure 14) correctly. The two small notches should point toward the
cutaway in the Right-Side Frame (D).
5. Remove the Shear Plate (E, figure 14).
6. Remove the Transport Sensor (A) by unscrewing the screw (L) holding it to
the Upper Paper Guide (C) with a #1 Phillips screwdriver.
Keep track of the cable routing for reinstalling the Transport Sensor (A).
See the next illustration and instructions for freeing the Transport Sensor
Cable.
Note: Reverse these procedures to reassemble the Right-Side Frame.
