🛠️ Extra Tape on the Back of the Panel – Check Sensor B1

Issue:

If your NikMann edgebander is leaving extra tape on the back of the panel, it is likely caused by a malfunction or misalignment of Sensor B1.

🔍 What is Sensor B1?

Sensor B1 is a laser sensor located on the right-hand side of the machine, next to the feed fence. It plays a critical role in the sequence timing of the edgebanding process by detecting panel position as it enters the machine.

⚠️ Why This Causes Extra Tape:

NikMann edgebanders use an integrated PLC with an HMI panel to control the workflow. If Sensor B1 fails or is obstructed:

• The machine may not detect the end of the panel accurately

• This causes the trimming or cutting units to delay, leaving excess tape on the trailing edge of the panel

✅ How to Fix It:

1. Visually Inspect Sensor B1

   • Ensure the lens is clean—wipe it with a dry cloth if dusty or dirty.

   • Check for any physical damage or wiring issues.

2. Verify Sensor Alignment

   • Sensor should be properly aligned with the feed path and unobstructed.

3. Check Sensor Status in HMI Panel

   • Go to diagnostics or sensor input status to verify if Sensor B1 is registering panel detection.

4. Reset and Test

   • Restart the machine and run a test panel to confirm the issue is resolved.
