FUNCTIONAL DESCRIPTION

The 926 Knife Assembly consists of the following modules:

Blade Assembly

Drive Board

DC Drive Motor

Solenoid

The Knife Assembly is attached to the front of the 9835 Printer beneath the print module. It is fastened to the printer base with three fasteners and has two wiring harnesses that connect to the 9835 Feature

Board at connectors CN4 and CN5. A separate harness carries power to the knife from printer control board connector CN11. The knife drive board also has a connector to attach cabling to the 928 Stacker Assembly.

Functional Description

The Knife Assembly is controlled by the Feature Board installed in the 9835 Printer. All power to the knife is provided by the printer via cabling from the printer control board. The rotary knife has a helical blade positioned below the supply path and is activated by the knife solenoid.

The knife is driven by a DC motor controlled via software by the printer. When the knife is enabled (by software) the motor is turned on and a solenoid, located on the Blade Assembly, is energized, and the knife blade completes one rotation, producing a cut tag. (The motor runs constantly as long as there is power to the knife.)

The Knife Assembly also has circuitry to provide 12 Vdc power and necessary control signals to the attached 928 Stacker Assembly. The functionality of the stacker is explained in Appendix D.

TROUBLESHOOTING

Drive Board circuits generate two error codes to assist in the detection of knife failures. Error 759 indicates that the knife is not moving and Error 760 indicates a knife jam.

The following paragraphs contain suggestions for troubleshooting the two conditions. Voltage tests are also included to further isolate a knife failure.

Evaluation of Error 760

The printer software reports an Error 760 when a knife jam is detected. The following checks are suggested to correct the problem:

1.Turn printer off.

2.Check supply path for jammed tags, or obstruction in path.
