3.7 Punching Accuracy Inconsistent

1. Check if the die is locked down properly, by inspecting the die
lock plunger. This is described in Section 4 (A) of the
StreamPunch Ultra/Ultra MP User Manual.
Die is properly locked
Yes- Go to Step 2;
No- Lock the die properly and return to normal operation
2. Punching will be inaccurate if Solenoid SOL 6, SOL 7, or
SOL 8 is not disengaging the roller completely when actuated
(punched holes will be shifted towards the trail edge of the
sheet in this case).
• Do the following to check whether SOL6, 7 or 8 is causing
the punch accuracy inconsistency,
1. Leave the front door open and insert an interlock
cheater.
2. Leave the jam access panel of area #5 open.
3. Run a 2~3 sheet job in punch job through the printer.
4. Punched sheets will collect near area #5, gently pull
the sheets and inspect the punch accuracy.
5. If the punching accuracy is good, it means SOL6 or
SOL7 or SOL8 is not functioning properly.
6. Do RTP 4.3 to Check Solenoids SOL 6, SOL7 and
SOL8.
For Double punched sheets, do RTP 4.3 to check Solenoids
SOL 4 and SOL 5 in addition to the above steps.
This clears the fault
Yes- Return to normal operation;
3. Do ARP 3.1.1 to remove the Punch module and do Steps 4, 5
and 6.
4. Do GP 6.27 Die Lock Mechanism and Die Rail Springs
Inspection.
This clears the fault
