Models C-320C and C-380C Models C-320C and C-380C are confetti-cut shredders with these characteristics: Shred size of 5/32 x 1-1/8 inch (3.9 x 30 mm) Optimum cutting capacity 14-16 sheets of letter or A size, 20 lb. paper. Maximum paper width up to 10 inches (25.4 cm) wide for the ... -
Page 7: General Maintenance
General Mantenance The shredders are designed to perform consistently with a minimum amount of maintenance. This section contains recommendations for external and internal cleaning, inspection, and lubrication. External Cleanng Clean the exterior of the shredder with a soft cloth. Moisten the cloth with a mild solution of detergent (such as dish-washing liquid) and warm water. -
Page 8: Control Panel
If used at or near capacity, the machines should be oiled every time the basket is emptied, when it becomes noisy, and when it is serviced. Use Fellowes Powershred Lubricant (#35250) or other non-aerosol vegetable-based oil in a long-nozzle container. Do not use flammable synthetic oil, petroleum-based products, or aerosol lubricants of any kind. -
Page 9: Troubleshooting
Troubleshootng 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 Problems Paper jams and a full wastebasket are two common problems. Indicator LEDs on the shredder cover help to identify these problems. -
Page 10: Electrical Problems
To clear a buildup of paper shreds from the underside of the cutting assembly (also called birdnesting): Unplug the shredder. Check the wastebasket and empty if full. Replace the basket and make sure the paper full switch is engaged fully. Plug in the shredder. - Page 11 To test for a faulty main PC board: Plug the shredder into the power source. If the shredder has a disconnect switch, flip it to the ON position. Make sure the shredder is turned OFF at the control panel. Remove the housing cover. Disconnect the LED PC board from the main PC board.
- Page 12 Locate the pins where the control panel (keypad) is plugged in and numbering the pins 1 through 5, follow this sequence to test the LED PC board: Jump pins 1 & 2 Cutters should rotate forward. Jump pins 1 & 3 Auto-mode: the green LED on the left-hand corner of the PC board should light indicating the shredder is on.

Page 13: Mechanical Problems
Mechancal Problems Mechanical problems can often be identified by listening to the sound of the machine when it is operating and observing whether the paper cutting capacity drops. If a confetti-cut machine is making excessive noise, it may need to be lubricated. -

Page 23: Remove/Replace Pc Board
Remove/Replace PC Board The PC board is located at the right side of the cabinet shelf. It rests on a support base that is attached to the cabinet shelf. Some of the wires leading to various components are hard-wired to the board, others such as the basket full sensor and the operator panel cable, can be disconnected from the board or the component. -
Page 24: Mechanical Assemblies
Mechancal Assembles The motor and the cutting assembly are the major mechanical assemblies in the shredder. Remove Cuttng Assembly and Motor from Cabnet The gearbox protects the gears and supports the cutting assembly and motor. The bearing plates support the cutting assembly. Consult the wiring diagrams as needed. -
Page 25: Remove Gearbox
Remove Gearbox The gear assemblies are the same for the C-320/C-320C and the C-380/C-380C shredders.

Page 32: Current Limit Adjustment
Current Lmt Adjustment The current limit adjustment is preset at the factory. When a PC board is replaced, this setting may need to be checked and adjusted. The current limit adjustment screw is located on the PC board. When adjusted properly, feeding more than the maximum recommended quantity of paper may cause a paper jam. - Page 33 Reassemble the shredder and test the basic shredder functions, including: Make sure the Ready Light (green) shines brightly when the power is on. This indicates the correct LED alignment between the PC board and the cover. Open the cabinet door to make sure the Door Ajar light is working.
