Ribbon Spool Drive Motors

wo DC ribbon drive motors are mounded to the back of the module wall. Each motor drives a ribbon spool. The motors are connected directly to the Control Board Assembly via separate two-wire harness.

Supply Deflector and Bi-Cell Emitter (IR LED)

See Chapter 8, “Supply Sensing Systems” for more information.

Ribbon Transfer Rollers

The two ribbon transfer rollers allow ribbon tension adjustments. Each roller has an eccentric which allows slight skew adjustments to each, which in turn affects the ribbon tension.

Functional Description

The print module, performs ribbon drive operations, provides mechanical ribbon tension adjustments, performs print functions, helps maintain supplies tracking, and houses half of the sensor assembly. It is controlled by the Control Board Assembly.

Ribbon Drive Operation

The ribbon drive operation is made up of two ribbon spools, two 25Vdc drive motors, and two ribbon transfer rollers. It is controlled by the Control Board Assy. Each drive motor sends continuous information to the Control Board Assy. where it is used to evaluate ribbon conditions, maintain optimum ribbon tension, and sense the end of ribbon condition. This system eliminates the need for ribbon sensors.

Printing

The printhead has a line array of 832 dot elements sized to produce 203 dots per inch. Printing occurs by sending image data to the printhead one line at a time. Each time a line of data is received, corresponding dots on the printhead are heated to create an image line on the stock. Successive image lines generated across moving stock make up the total image. The Control Board Assy. controls all image data sent to the printhead, and regulates the energy level of the printhead. Energy levels are raised and lowered to create darker or lighter print respectively.

FEED ASSEMBLY

The feed module components are mounted on a metal frame positioned beneath the Print module and

fastened to the printer base. Components of the feed module are:

Bearing

Blocks

Spring

Latch

Figure 2- 2. Feed Assembly

Platen Module

The platen rollers are on top of the feed module frame just beneath the printhead. It is held in place by two bearing blocks latched on the frame sides. The inner side of the platen roller shaft extends through the inside wall of the feed module where a drive gear is attached.

24VDC Stepper Motor

The stepper motor is located behind the mid-frame of the printer. Its drive shaft and gear extends through to the space between the printer mid-frame and the feed module frame.

Lower Supply Guide and Bi-Cell Sensor

See Chapter 8, “Supply Sensing Systems” for more information.

Printhead Latch

The printhead latch is spring loaded and mounted on the outside of the feed module frame; within the latch fascia. It locks the printhead in position.

Functional Description

The feed module transports supply through the printer and across the printhead. It also maintaining proper alignment, tension, and speed. This is accomplished by sensing the stock position while securing the printhead down onto the platen roller. Major functions are supply feeding and supply sensing. See Chapter 8, “Supply Sensing Systems” for more information.
