Canon DU7-1175-000 service manual To Clear a Paper JAM

Step 8: Install the die set. Test the Professional Puncher-A1 system running first one page at a time, then two pages then 5 pages, then 10 pages and lastly run 50 test pages.

Step 9: Replace the cover and run a few more test jobs.

Step 10: Skew Adjustment: Check for proper Hole alignment to paper edge.

The back gage is designed to give you some adjustment when the three screws are loosened.

It will give you up and down play, which allows you to remove skew.

The ideal situation is to have the back gage all the way to the top position.

If not, paper can slip past the paper stops and give you a deep punch. This may occur if the back gage is tightened into place in it’s bottom most position. This situation is most likely to occur when using the VeloBind or PB die sets, which are at one end of the Back Gage tolerance spectrum.

Three-Hole Die Set: At the other end of the Back Gage tolerance is the Three-Hole Die Set. If the customer owns a Three-Hole Die, check this die to see if it is easy to insert and remove. If the die is too tight you will need to lower the back gage slightly to achieve the tightness you desire, while still retaining the PB and VeloBind functionality mentioned above.

Now you need to run some paper and check for skew, at this point you can now use the three screws to adjust skew if needed. After the adjustment is made re test with the three-hole die. If all is well re test with the VeloBind die to make sure there are no deep punches.

Step 11: Back Gage Adjustment to eliminate Deep Punching: Check for proper operation with PB Die Set: In some cases, using a PB Die Set, you may have an occurrence of a “Deep Punch” symptom. If this shows up during testing, loosen the three main screws that secure the entire Back Gage Assembly, push the entire mechanism upward, taking up all play, tighten the three screws securely. Test approximately 200 to 500 sheets of paper through the PB die. Check for no deep punching and no paper jamming in the Die Set area
