LUMISCAN ACR-2000 READER SERVICE MANUAL - SECTION 5.0 SERVICE ADJUSTMENTS
5-3
1. Laser Light Verification
Install the Interlock Key to allow operation of the Laser with the cover off. Remove the optics cover on the
back panel. Turn on the ACR-2000 Reader. Observe that the beam is projecting onto the Galvo Mirror. If the
power is on and the Interlock Key is installed and there is no Laser light, the Laser Module is suspect.
2. Folding Mirror
Disconnect the J3 power cable to the Galvo PCA. Ensure that the beam is projecting to the center of the
Light Collection Chamber +/- 0.5 inches. If not, rotate the Galvo Motor or the Galvo Mirror to achieve
center. Re-connect the Galvo PCA power. Go to the command prompt. Navigate to the Lumisys “tools”
directory. Start the DDT menu. Start the Galvo by selecting option 20 from the DDT menu. Adjust the
height and the tilt adjustment screws that are located on the folding mirror until the beam is horizontally
centered and vertically level in the Light Collection Chamber opening. Remove Galvo PCA power at J3. If the
beam is not horizontally centered, start step 2 over again.
3. Plate Detector Alignment
Note: This adjustment applies only to readers with Data Acquisition PCA P/N’s 0070-735 and below.
This adjustment is not necessary for readers with Data Acquisition PCA P/N’s 0071-592 and above.
Go to the command prompt. Navigate to the Lumisys “tools” directory. Start the DDT menu. Select
option 20. Press “I” to measure the “Isfilm” signal. Press “ P” to plot the “Isfilm” signal. You should see
three spikes approximately 1600 in amplitude. If these spikes are not seen, the beam is not hitting the
three detectors. Use the roof mirror to raise or lower the beam until all three spikes are visible.
