Short AOM life on Frontier 340 (1000SE)

In the past, AOM devices last about 5 years. For the last 2-3 years we have been getting lass than 1 year before they fail. The recent failures are discovered by noticing banding in the prints. A Frontier expert advised us to make sure there is no corrosion in the grounding connection and that there is no floating ground. We have taken care with the ground but we are still getting short life from the AOM. What else should we check?

Fuji 340 AOM driver has two channels. Which one always fails - always the same, or different?

AOM driver has power suppliers, inputs, outputs and temperature sensor signal. Nothing else there.

Are your AOM drivers original ( get from Fuiji and made in Japan ) , or fake AOM driver ( from Ebay, sent from China ) ?

One was a used one from another used 340 we own probably from Fuji. The others were from China. They were labeled Panasoinic but I know that can be fake. I am thinking it is just a poor quality supplier but wondered if there was any other possibiliy. Do you know a source for good quality AOMs for the 340? The last two failures were a banding a, not a color shift so I can't anser which channel fails.

Yes, the lifespan of replicas from China is unclear. They can copy the appearance of the product, but the inner content is of poor quality.
Used original AOM driver taken from old Fr330/340 may work longer than new one from China.
You can obtain used original AOM drivers on ebay.com, from us or the other forum members.

AOM driver is connected to AOM crystal and not connected to laser head. Laser heads work as independent unit. In Fuji laser head is controlled by LDD board and in Fuji made by Noritsu - controlled using laser driver. 
AOM drivers from China are some lottery. Nobody can say how long they work. Original AOM drivers from Fuji are made by Panasonic. It is reliable company. Original AOM drivers are made in Japan. So quality is better.
