INTRODUCTION

1.1 SCOPE AND PURPOSE OF MANUAL

This manual is a reference for system integrators and

maintenance technicians. This document contains all the necessary

information required to successfully integrate the Cybertech A822P

impact printer into a system. This includes theory of operation,

hardware installation and software specifications.

1.2 GENERAL DESCRIPTION

The Cybertech A822P impact printer is designed for low

operational cost and require no maintenance other than paper and

ribbon replacement. Based on Cybertech's field proven design

these printers allow for enhanced performance, small size and

economy. The single board controller features an on board power

supply with the capability to print the highest quality

characters.

These printers are ideally suited for imbedded applications where

high speed, exceptional print quality and reliability are

paramount.

OPERATION

2.1 GENERAL

The Cybertech A822P is a impact dot matrix printer. Data enters

the controller via a serial RS232 port. This data is then

converted to characters or commands. The characters are then

converted to a bit images, stored in the dot buffer RAM. The

contents of this buffer are then loaded into the print head.

Printing starts when a line overflow occurs or a carriage return

is received. The paper empty sensor is checked. The dot solenoids

are arranged in two 4 wire print heads which produce one half of a

character at a time. The dot solenoids are then energized for a

time. When an electrical current is applied to a solenoid the wire

is activated causing the wire to strike the ribbon and paper.

After the dot row is printed, the paper advances to the second

half of the character. This completes a print cycle and produces

the print image. Direct impact one of simplest operations among

available printing techniques.

2.2 CONTROL PANEL

2.2.1 REPRINT/FEED SWITCH

When this switch is actuated in the REPRINT position after the

printer is first powered on a test print will occur. When data is

sent to printer containing the Start/Stop message the last cycle

will print. To clear the reprint buffer, depress the REPRINT

switch and hold for greater than 4 seconds. The LED will flash

indicating the reprint buffer is clear. If REPRINT is actuated

during power up and pins 2 & 3 on the serial port are shorted, the

printer will print the test message until a fault condition

occurs. This is used for factory test.

If the switch is actuated into the FEED position paper will be

feed by the printer; if equipped the take-up will also attempt to

take up paper. If the switch is in the FEED position at power up

the Printing will be reversed (upside down)- note this condition

stays set until the same FEED switch on power up cycle is

repeated.

2.2.2 FAULT LED

A flashing LED indicates the printer has a fault condition. The

fault may be out of paper or the printer is jammed. The actual

fault may be found by a status read of the serial port. In normal

operation this LED will be on.

2.3 PAPER AND TAKEUP LOADING

1. Open front cover of printer to access paper compartment.

2. Tilt the printer mechanism forward to access the paper holder.

See figure 2.1 for the following steps.

3. Remove old paper core.

4. Notice the loading diagram on the back of the printer case.

Refer to this when loading the paper.

5. Insert the new paper into the paper holder with loose end of

paper placed into the slot at the top of the print mechanism.

The front panel LED should be flashing.

6. While holding the paper in the print mechanism, push the front

panel switch to the ‘Feed’ position (Up). The paper should

feed into the print mechanism and out the front. Refer to

Figure 2.2.

7. Continue feeding paper until there is about 8 inches of paper

exiting the print mechanism.

8. Guide the paper between paper guide rod #1 and the plastic

window until it exits at the top paper guide rod #2. Make sure

the paper goes around this guide correctly. Refer to Figure

2.3.

9. Make a slight bend in the paper edge and place bent paper edge

into the slot on the take-up spindle. Hold the paper on to the

paper spindle.

10. Push the front panel switch to the ‘Feed’ position, paper

should then wrap around the spindle. If this doesn’t, remove

paper and start at step 9 again.

11. Once the take-up is loaded, push the front panel switch to

the ‘Reprint’ (down) position. This will start a print cycle

(test print or reprint).

12. Close the front cover while the print is taking place. This

will keep the paper tight around the take-up.
