Solution

This section includes a detailed troubleshooting procedure. If at any point you feel that you have found the source of the problem, you can either process several plates to verify that the problem has been resolved, or you can continue to the end of the procedure.

1. Review all generic troubleshooting questions with the customer.
2. Open the front door and manually remove the plate(s) from the machine.
   Note: If two plates were found stuck in the punch, refer to the troubleshooting document, Double Loading.
   If the plate(s) cannot be removed from the punch, close the front door and release the punch. If you cannot release the punch, answer all generic troubleshooting questions and then, contact your service representative.:
   1. If the machine is a:
      • Local 2 machine, perform TIP #47.
      • Local 3 machine, release the punch using the punch direction inverter cable.
   2. Perform Tip #45.
   3. Further inspect the punch rod and verify whether it is damaged and/or deformed. If it is:
   • Replace the punch.

   If the punch rod is intact:

   • Perform punch rod home position adjustment.
3. Visually inspect the removed plate in the area that is, or should have been punched. Look for:
• Rough edges.
• Partial cut.
• Dent, instead of a punched hole or notch.

If found, answer all generic troubleshooting questions and then, contact your service representative, replace the punch.

4. Visually inspect the punch to verify whether the powerful punch motor has been installed. If it has not been, perform FCO 27281.
5. Further inspect the punch. Look for damaged and/or missing punch guides. If one or more of the punch guides is damaged and/or missing, answer all generic troubleshooting questions and then, contact your service representative.
   • Remote only: Ask the customer whether the guide is missing from the spiral punch or is a custom punch. Then, order the punch reliability FCO 27707, Version B, have it shipped to the customer, and schedule a field service call.
   • Install or replace the punch guides, as required according to the punch reliability FCO 27707, Version B.
6. Visually inspect the punch hole for debris, plate slug and/or dirt. If found, pass the edge of a plate (preferably a used one) back and forth through the punch to clear the slug and/or debris.
7. Close doors, as required. Then, perform plate loading to verify whether the problem is resolved.
8. Open the cassette and insert it into the machine. Leave the front door open and, using a cheater, perform plate loading.
   Note: If the customer is using a dual cassette, be sure to redefine the cassette as dual loading before leaving the site.
9. Watch the plate as it is loaded and verify whether the problem has been resolved.
10. Perform the steps described in, "Before You Finish".
