Noritsu Minilab 6073 Error or Lines on Prints -AOM Driver and Laser Troubleshooting Tips
________________________________________________________________________
Another set of questions we get here at The Laser Refinery Inc., is how can you tell if the lines being generated or the 6073 error is really the laser or it's just a bad AOM Driver or Bad Laser Conroller.

The solution is a matter of troubleshooting by process of elimination, there is no setting that you can check. Just follow these instructions.
___________________________________________________________________________
Special Note: These AOM Driver Troubleshooting instructions will not work with QSS-37XX series machines because those machines have only 1 AOM driver.
______________________________________________________________________________
AOM Driver Troubleshooting

1) Label each AOM Driver with the corresponding color on the BNC (big round stainless steel connector) connected to that Driver. For example: On the AOM Driver with a BNC that has a Red sticker on the cable label that AOM Driver with the letter "R" on top etc. Do this for Green "G", and Blue "B" also.

2) Remove the questionable driver, by removing ALL Cables and physically removing that driver. Some people try to swap cables around but this will not work because all the cables are not long enough, and each cable must go with that particular color driver. Therefore the driver must be physically removed.

3) Replace that driver with one of the other drivers. For example; swap the Red AOM Driver (if this is the one in question) with the Green AOM Driver. Again, I will repeat; some people try to swap cables around but this will not work because all the cables are not long enough, and each cable must go with that particular color driver. Therefore the driver must be physically removed.

4) Run the machine and see if this error/problem occurs again, but this time with the other color. In other words, if the problem was originally with the red laser or AOM did swapping the AOM driver cause the problem to go to the other color i.e. the green laser or AOM. If it did not you may have a bad laser or bad laser controller. If you want to troubleshoot the laser controller follow the intructions below.
__________________________________________________________________________

Note: The following instructions are for Type A and Type B laser engines only. They will not work for Type Ff laser engines because those laser engines have two different types of laser controllers.

Laser Controller/Driver Troubleshooting

There are two laser controllers on most Noritsu minilabs, even though there are three lasers, that is because the red laser is controlled by the laser I/O board and is built into that board. The only two individual controllers that can be swapped are the green and blue ones.

1) If the laser controllers do not have color coded stickers on them, then label each controller with the appropriate color. In order to find out what that color is take note of the color on the connectors going to each controller. You will find that on each of the laser controllers, one of the largest connectors will have a blue label with serial number and on the other laser controller, that same type of connector will have a green label with a serial number. Label each controller with the color of those labels. Simply mark one laser controller  "B" for Blue and the other "G" for green.

2) Take note of the laser controllers physical orientation by taking a picture or labeling one corner. Remove the questionable laser controller, by removing ALL Cables and physically removing that laser controller.
Note: On some controllers there is an aluminum base plate that goes with the controller. There are only 4 or 5 screws that hold the controller down around the edge ONLY. Do NOT attempt to remove ANY screws in the middle. Removing any screws from the middle may RUIN THE CONTROLLER. Do not Remove ANY screws from the middle.
Some people try to swap cables around but this will not work because all the cables are not long enough, and each cable must go with that particular laser controller. Therefore the laser controller must be physically removed.

3) Take note of the other laser controller's physical orientation by taking a picture or labeling one corner. Now remove the other laser controller, by removing ALL Cables and physically removing that laser controller.
Again, Take Note: On some controllers there is an aluminum base plate that goes with the controller. There are only 4 or 5 screws that hold the controller down around the edge ONLY. Do NOT attempt to remove ANY screws in the middle. Removing any screws from the middle may RUIN THE CONTROLLER. Do not Remove ANY screws from the middle.

Place this controller where the questionable one was and the questionable one where this one was. Remember that the physical orientation is different for each controller, so remember this and place them in the proper orientation. Screw the laser controller down and connect all the cables.

4) Run the machine and see if the error or problem occurs again, but this time with the other color. In other words, if the problem was originally with the Blue laser, did swapping the Laser Controller cause the problem to go to the other color i.e. the green Laser. If it did not and you already tried the AOM Driver troubleshooting instructions above, you have a problem with the laser engine and it will need to be removed and sent for repair.
