I just decided to do a slide a day project on my newborn (almost - we're headed to the hospital in a little while) son. I want to date each slide to keep the sequence clear. So I ran one of my few remaining rolls of Polachrome through the N90. Photos could have turned out better, but more importantly, there are no dates. Is my data back broken, or does the backing on Polachrome block the printer? Does anyone either know if there is a Polachrome issue, or a way to test my MF-25 without running a roll through it (a bit busy to spend time in the darkroom right now).
