5Ć30 Functional Overview

C3187Ć90000

The carriage processor dedicates its address/data bus to interface with the nozzleĆtiming

ASIC. The ASIC is also connected to the shuffler ASIC by a synchronous serial channel. The

nozzleĆtiming ASIC applies the shuffled data it receives from the shuffler ASIC to the

cartridge drivers, controlling the firing time and sequence of the printĆcartridge nozzles.
The outputs controlling the print cartridge drivers are disabled while the reset signal is

active. A voltage supervisor monitors the logic supply (+5V) and generates a reset signal to

prevent firing nozzles during power transitions. The falling threshold for reset is 4.71V

worst case.

The carriageĆprocessor serial port is used to communicate with the servo processor. The

servo processor controls the carriageĆprocessor reset signal.

The carriage processor controls an eightĆchannel serial A/D converter. The processor drives

the A/DĆconverter control signals, chip select and shift clock.

The carriage processor can verify the firing of each printĆcartridge nozzle.

Firing a nozzle causes a voltage drop at the ballast resistor for that nozzle. A comparator

senses the voltage drop at each ballast resistor and outputs a pulse to a processor counter.

This enables the processor to determine whether each print cartridge is inserted properly.

A thermistor mounted on the carriage PCA allows the carriage

processor to sense ambient temperature. The processor can adjust the amount of energy

delivered to a print cartridge by changing the nozzle firing time though the nozzle timing

ASIC. The plotters compensate for changes in ambient temperature and self heating of the

print cartridges based on the data provided by the carriage processor.

The plotters calibrate the writing system to compensate for alignment errors due to

mechanical tolerances using an optical line sensor. The sensor is capable of precisely

measuring, within the field of view of the sensor, the position of one line relative to another.

The sensor measures both horizontal and vertical line positions. The plotters also use this

sensor to determine the location of the media edges in the carriage sweep axis.

The sensor employs a quad photo diode array with illumination from a diffuse

LED. A simple optical system employing two lenses forms an image of the test pattern on the

photo diode array. A transimpedance amplifier converts the current generated in each photo

diode to a voltage. The carriage processor samples the resulting voltage through the A/D

converter.

The accuracy of the line sensor after selfĆcalibration when measuring lines spaced

at 1/300 inches is 0.3 mil. When determining the position of the left or right media edge, the

sensor accuracy is 6 mil.
