Troubleshooting

Troubleshooting the shredder begins with checking the machine for possible faults. Possible
causes for machine malfunctions include:


Paper feed problems



Electrical problems



Mechanical problems

Paper Feed Faults
Paper can become jammed if the paper is misfed. Paper may also jam if the waste bin is full or if
there is a build up of paper shreds along the underside of the cutting assembly.
The ECC and Mechanical Bin Full System help to identify paper feed faults.
CAUTION! Never attempt to force jammed material through the machine.

If paper misfeeds or shredder capacity is surpassed and shredding stops the shredder will
attempt to reverse the paper out.
CAUTION! The shredder may be damaged if you alternate too rapidly between forward and
reverse.
Electrical Faults
The most common electrical faults result from:
1. An opened cabinet door
2. Loose wires
3. A defective PC board
4. Bin full detection system not operating correctly
5. ECC not operating correctly
If the waste bin is not placed properly in the cabinet, the shredder will not operate:

The Door Open LED will help to identify this problem.

Check the door to make sure it closes properly and engages the door open switch.

Press the Power button on the Control Panel Button.
If paper is in the entry slot, and the shredder does not operate:

Check to see if the power on the Control Panel Button has been engaged.

Make sure unit is plugged into the wall outlet.
If the PC board is defective:

The shredder may not run at all.

Another indication that the PC board is defective might be if the shredder runs in reverse,
but not forward or the LED lights do not turn on.
If the Auto start sensors are defective:

The shredder will not be able to detect paper being inserted.

Constant run on may occur.
If the capacitor is defective:

A typical problem caused by a defective capacitor is limited or no motor function.
If the Bin full detection system is not operating correctly:

The bin full indicator will illuminate.

The shredder will not accept any paper.
If the Electronic Capacity Control (ECC) is not operating correctly:

The ECC gauge will illuminate without any paper having been inserted for shredding.

The unit will not shred.
