2901 weird prints


Johnson Camera

Recommended Posts

During the middle of a print job, the prints started looking like "sample1.jpg". Restarted the machine, and started getting prints like "sample2.jpg". All prints, even the daily setup, look like sample2. Turned the machine off and went home. The next it still printed the same. Now we got the following errors:

6901-0080 (once)

6820-0006 (several times)

Have removed and reseated the Image Processing board and all the boards and cables attached. Reloaded backup software. No change. Sample1 looks like a 1 cm. strip of the same part of the image repeated with a color change cycling every time. Sample 2 still looks like a 1 cm repeating strip. The band is across the print, not in the direction of travel.

Any ideas?

Under the MLVA lamp is a high speed spinning filter wheel. They have a habit of letting go and a filter can shatter at speed or crack and loose a part of one. The speed that it spins is critical also, have a look at the filter wheel with a touch through the glass window,

I understand that a bad filter wheel could cause color stripes, but would it cause the same 1 cm of the image to be repeated along the length of the print?

OK, I watched the filter wheel slow down and all looks correct. While up to speed, the window appears clear. When it finally slows down each color segment appears intact.
