1. Remove the small E-Clip (B) and the Worm Wheel Gear (H).
2. Cut the two tie wraps holding the Transport Sensor Cable to the Transport-
Auto Cutter Assembly and the other cables.
You can now separate the Transport Sensor (A, figure 13) and cable from
the Transport-Auto Cutter Assembly. Keep track of the cable routing for
reinstalling the Transport Sensor.
3. Remove the outer E-Clip (B) and the Rotary Cam Gear (J) from the Drive
Wheel Assembly (R, S, Q, B, K) and slide the Drive Wheel Assembly out.
Don't lose the Brass Pin (K) or the Drive Wheel Bearings (Q) from the
Drive Wheel Assembly. You do not need to remove the other E-Clips unless
you are disassembling the Drive Wheel Assembly.
When reinstalling the Drive Wheel Assembly, be sure to line up the Drive
Wheel Bearings (Q) correctly. The two small notches should point toward
the cutaway in the Left- and Right-Side Frames.
4. Remove the Upper Paper Guide (C, figure 13) by unsnapping it from the
Left-Side Frame (G).
Do not bend the Paper Guide Pin (M, figure 13) that connects the Upper
Paper Guide to the Lower Paper Chute (C, B, figure 13). When reinstalling
the Upper Paper Guide, hook it to the Left-Side Frame at both ends.
5. Remove the E-Clip (B) and the Rotary Cam Gear (J) from the Auto Cutter
(A) and slide the Auto Cutter out.
Don't lose the Brass Pin (K) from the Auto Cutter (A).
When reinstalling the Auto Cutter (A), face the blade away from the Back
Plate (D) and place the Brass Pin (K) in the Auto Cutter so it is
perpendicular to the Auto Cutter blade. Place the Rotary Cam Gear (J) on
the Auto Cutter with the flat side of the inside portion of the gear facing the
Micro Switch (N). If the Auto Cutter is not installed correctly, it will not
work. Do not put the Rotary Cam Gear (J) in upside-down.
6. Remove the remaining two E-Clips (B) and Rotary Cam Gears (J).
7. Remove the two screws (M) holding the Cutter Motor Assembly (L) to the
Left-Side Frame with a #0 Phillips screwdriver.
8. Remove the Micro Switch (N) from the Left-Side Frame (G) by unscrewing
the two screws (O) with a .050 inch Allen™ wrench.
Be careful not to lose the Spacers (P) behind the Micro Switch (N).
9. Remove the Back Plate (D) from the Left-Side Frame (G) by unscrewing
the hex head screw and lock washer (C) with a 7/32 inch nut driver.
Be sure that the lock washer stays with the hex head screw. Replacing the
Back Plate (D) without the lock washer may cause the Back Plate to
become loose and damage the printer.
