Frontier 340 pictures AND feeds turn yellow

Hi,

frontier 340 (using cp49 of course) pictures and feeds turns yellow some time after printing. Time is from 2-3 minutes if paper is exposed to sun to 40-50 minutes if left on table exposed to indoor lighting.

Fuji representative said it is possibly either p1 or laser problem. I changed p1, same thing. But I don't see logic behind idea that it could be faulty laser, because feeds turns yellow and it is my understanding, that laser does not activate on feeds.

So I am thinking about changing p2 also. Or maybe I am not getting something here?

Thanks. Andis.

That sounds like improper blixation.  Silver and or dye couplers are being retained in the paper (maybe along with some developing agent) and "printing out" (blackening to metalic silver due to exposure to light and reducing from silver halides without the need for a chemical reduction process).

Check the pH of your blix, and the yellow dot on your control strip (Y-max) for retained silver.

If you need more specific instructions due to inexperience, just ask!  :-)
