FLIGHT COMPARTMENT PRINTING SYSTEM -FLIGHT COMPARTMENT PRINTER
General * Interconnection board
* 2 connectors. The printer can print an 8.5 inch page. The printer resolution is 300 dots per inch. You can load a full paper roll of 125 linear feet into the printer. The printer uses the U.S. standard 8.5 inch roll or the A4 European Air standard paper.
Physical Description
The printer weighs approximately 12.2 lbs without a paper roll.
These are the dimensions of the printer:
*
5 inches high
*
10.75 inches wide
*
10.25 inches deep.
The printer contains all the mechanical components and electronics necessary for printer operation.
The mechanical components include:
*
Printer head
*
Rollers to move the paper
*
Motor and drive system.
The electronic components include:
*
Power supply
*
Processor board
*
Controller board

FLIGHT COMPARTMENT PRINTING SYSTEM -OPERATION
General
There are five functional buttons on the printer. Two of the push buttons show printer status. Three of the push buttons control the printer.
Indications
The amber FAIL light comes on when a failure occurs that you can not repair on the line.
The amber PAPER light comes on when the printer is out of paper or when there is a paper jam.
Controls
Push the SLEW switch to move the paper out of the printer. Release the SLEW switch to stop the paper.
Push the RESET switch to cause a power-up reset of the electronic circuitry of the printer. Printing will stop. Messages in the printer memory are kept in memory. A green bar on the switch shows during the reset.
Push the TEST switch to do a test of the printer. During the test, a test pattern for text prints. The test pattern shows all the text characters the printer can print. A 300 dots per inch test pattern for graphics follows the test pattern for text. A green bar on the switch shows during the printer test.

FLIGHT COMPARTMENT PRINTING SYSTEM-FUNCTIONAL DESCRIPTION
General
There are three main electronics boards to control the printer. They are the:
*
Controller board
*
Processing board
*
Interconnection board.
Controller Board
The controller board receives brightness controls from the dimmer control unit and the master dim and test module. These controls are to drive the lights on the front panel.
Processing Board
The processing board processes all inputs from the left and right AIMS cabinets. The processing board changes the data to signals to control the thermal print head.
Interconnection board
The interconnection board controls the flow of data between the processor board the controller board and the mechanical devices that print the paper.
The interconnection board controls the stepper motor and thermal print head to print on the paper. It also monitors the paper and door status. The interconnection board then turns on the lights on the front panel.
The stepper motor moves a roller system which controls the paper. A pulley/belt system control the speed of the motor output.
The interconnection board sends signals to the thermal print head to control what is printed. The thermal print head touches the sensitive side of the paper.
The paper assembly unit detects when paper is low or out and sends a signal to the interconnection board. The interconnection board then sends a signal to turn on the low paper indication on the front panel.
The door assembly unit detects when the door is open and sends a signal to the interconnection board. The interconnection board then sends a signal to turn on the fail indication on the front panel.
