AMIS-710330: 300dpi CIS Two-Level Digital Output Module

Data Sheet

AMIS

8.3 Adjustments

8.3.1. General Location of Test, Adjustment and Monitor Points

Figure 5: AMIS-710330 PCB Monitor and Test Points

Figure 5 shows the pictorial layout of the controls and the test points. These adjustment potentiometers and the test points are shown

relative to the connector and to the output pads for LED light power. This is a bird’s eye view of the PCB’s backside with the glass

window of the module facing down on the documents.

The test point labeled TV is for the analog image pixels, just as it is produced at the output of the CIS array section and prior to its entry

into the tracking digitizer circuit.

The test point labeled TR is the output of the tracking reference level from the tracking digitizer circuit.

The test point labeled TVD is the digital output from the comparator.

Offset adjust, R4, is a screw driver adjustment potentiometer, which is accessed through the adjustment hole as it viewed in Figure 5.

Gain adjust, R5, is a screw driver adjustment potentiometer, which is accessed through the hole as it is viewed in Figure 5.

8.3.2. There are Only Two Adjustments

These adjustments will be pre-adjusted at the factory, to the specific application of the customer, thus generally will not require

adjustments by the user.

The gain is adjusted by monitoring the test point TV with a scope, adjusting the gain potentiometer, R5, until the analog image pixel

levels are set to approximately a 2.0V peak with the module imaged on the a standard white target, similar to the standard white copy

or typing paper. (The probe should be grounded as close to the CIS module as possible. The ideal method for grounding would be to

place the probe right on the ground input lead, Pin 5, of the I/O connector.)
