GP 6.16 Bypass Paper Path Inspection and Cleaning
Do the following to inspect and clean the Bypass Paper Path.
Warning : Make sure you disconnect the machine from its power source
before cleaning. Failure to observe this warning could result in death or
serious Injury.
See Section 0, page vii for other languages.
1. Open the top cover and raise the Upper Bypass to access the Bypass
Paper Path.
2. Inspect the Bypass panel, rollers, and entrance guide for wear,
damage, and obstructions.
3. Inspect the rollers for wear patterns or groves. The roller surface
should be smooth and even. Make sure the rollers are clean. Clean
rollers with a soft cloth and alcohol.
4. Inspect the polished metal surfaces on the Upper Bypass and Lower
Bypass. Ensure the surface is smooth and free of debris. Clean the
Upper Bypass and Lower Bypass plates with a cloth and alcohol.
5. Ensure the bypass diverter moves freely and returns to the bypass
position.
GP 6.17 Timing Belt Inspection
Use the following procedure to inspect the Timing Belts throughout the
eWire. Inspect the Timing Belts if excessive wear or debris is observed, or
if the function of the components driven by the belt appears to be
compromised. Black dust around the area of a Timing Belt or frayed
edges could indicate that the Belt is close to failure.
Warning : Make sure you disconnect the machine from its power source
before cleaning. Failure to observe this warning could result in death or
serious Injury. See Section 0, page vii for other languages.
Procedure
Do the following to inspect the Timing Belts.
1. Inspect all timing belts for wear, missing teeth, frayed edges, and
cracks.
2. For replacement, refer to the heading for the appropriate module in
Section 4, Replacement Procedures.
3. Check for proper deflection of belts. The belts should be slightly loose
with approximately 1/4” deflection when pressed.
4. Belts that are too loose will not drive properly and belts that are too
tight can wear out prematurely or damage their driven components.
5. If the Belt has a Tensioner along the length of the Belt, the tension
can be adjusted by loosening the screws on the Tensioner, and
adjusting the Tensioner position until the proper tension is achieved.
