Functional Description

Power Transformer Assembly

The power transformer assembly is located beneath the printer’s back cover and includes three components:

Inlet Power Module

The power module is attached to the printer’s rear panel just in front of the Control Board Assy. Its face plate partially extends through the rear panel to allow users access to the power receptacle, fuse box/power selector and the on/off switch. It has wire attachments to ground the Power Transformer.

This module includes the following components:

International line cord receptacle

4.0 Amp, 250VAC Slo-Blow fuse

Line voltage enters at the cord receptacle and passes through a slow-blow fuse. The slow-blow fuse protects the system from damage by power surges. Line ground is provided to the printer via a ground harness connected to the bottom frame.

Power Transformer

The power transformer is available in three voltages: 110V, 115V, or 220V. It is attached to the frame base just below the print module. The transformer gets AC line voltage from the inlet power module and converts it to two AC output voltages. The first is sent directly to the Control Board Assembly for futher conditioning. The second output is sent to the bridge rectifier for additional conversion.

The power transformer assembly outputs the required AC and DC voltages for operation of the printer and sends both voltages directly to the Control Board Assy. Further conversion and/or distribution is made by the Control Board Assy. Major functions of the power transformer include providing power to the Inlet Power Module, Power Transformer, and to the Bridge Rectifier.

Bridge Rectifier

The bridge rectifier is a 1” x 1” assembly fastened to the printer frame base left of the power transformer. It has wire attachments to ground, the power transformer, and the Control Board Assy.

The bridge rectifier accepts the AC from the power transformer and converts it to DC. This voltage is then supplied to the Control Board Assembly for further conversion.

CONTROL BOARD

ASSEMBLY

The Control Board Assembly is located on the back side of the printer frame wall beneath the printer’s back cover. It consists of a mother board and a daughter board. The two boards are replaced as a single assembly. The board assembly is mounted on six quick-release aluminum standoffs. Three of the standoffs are threaded for retainer screws.

The board has three connectors (serial port, parallel port, and bar code verifier), the print contrast control, and three DIP switch assemblies. Two are mounted on the long vertical side allowing for external access. The third DIP switch is located on the daughter board. There is a connector across the top of the board and a hall effect sensor at the top right corner of the board to sense a “Head Open” condition. Eight additional connectors accept cabling to other printer assemblies.

The daughter board has a connector for cabling to the mother board, and two connectors for functional expansion.

Functional Description

The Control Board Assy. controls all electrical requirements for the printer and contains interfaces for controlling all printer functions, including Ribbon Supply and Take-up motors, Stepper Motor, Peel motor, Knife motor, and the Printhead. A single microcomputing unit consisting of a 32-bit RISC processor, 256K OTPROM (16 bits), and 256K (16 bits) of Dynamic RAM (DRAM) controls the interfaces. Major functions of the Control Board Assy. are:

Power Conversion

Memory

Printer Control

Operator Panel Control

Communications

Contrast Control

Hardware Power-up Settings (DIP Switches)

Peel Motor Control

On-Demand Sensor Interface

Knife Motor
