6820-16805 error on DLS 3011


Recommended Posts

I have a 6820-16805 error on a DLS 3011. When I start in the morning all works fine for 1 or 2 hours then suddenly I get white pictures with thin magenta vertical lines or half picture with these lines and the error message 6820-16805. (digital and filmscanner input) As I have a spare 3011 I changed image processingPCB, digital ice PCB, memories on image processing PCB, laser control PCB with clock pcb's and the LVDS PCI Pcb inside the computer, I also put the CPU from the spare machine but it has some other problems. All this has not changed the problem. I still have it. I don't have this spare PCB for DLS which is put on the image processing PCB but I thought this was only for scanning. I did tests the Noritsu engeneer asked me to do: When trhe problem is there, also setup prints are coming out white with magenta lines but I could burn a CD and all images on the CD where fine.

Anyone can help??

OK, just a feedback guys. I got a laser diagnostic software and it told me that green laser is 100% bad when the machine was warm enough,  in cold state it was OK at 80% only. I changed green with red AOM and it still said green laser 100% bad. I removed the laser from my spare machine and I put it in the one with 6820 error and????

all working fine now. Thanks for help and take this as a reference when you get this error. Noritsu staff told me: never happened that laser is wrong with this kind of error message.
