Why is my GBC Stack-and-Shred 600X shredder not working?

Accepted Answer

If your GBC Stack-and-Shred 600X shredder is not working, here are the checks to perform in order:

1. Power Supply

Check that the power cord is properly plugged in
Press the power switch located at the back of the device
The device operates at 120 V, 60 Hz - confirm your electrical setup

2. Warning Indicators

The device has several indicator lights. Check the status of the indicators:

Bin Full: Empty the waste bin. The device will not operate if the bin is full
Cover Open: Ensure the upper compartment is closed properly
Paper Jam (red indicator): See section below

If the jam indicator lights up red:

Alternately press the forward and reverse buttons for automatic unjamming

Check that you are using the correct mode:

Auto-Feed Mode (600 sheets max at 80 g/m²): press the automatic mode button
