Noritsu 3300 Black and white printing issue

[dailysetup]

Hello,

I have recently purchased and installed a used laser unit for my 3330 due to a blue laser failing. I have not had issues with my prints since.

Although I've noticed this occuring when printing black and white images.

The first couple prints are normal and then the prints start to go a shade a either yellow or magenta.

Is this something to do with a laser setup I haven't yet completed?

See attachment: Top image is the first print, bottom print is the prints to follow after the first print.

You can see where the laser has started to change about half way into the image.



Thanks,

It's most likely an AOM driver problem.

To me the prints look cyan/ Red which would indicate a problem with the Red AOM driver.
