What OHP and Alt Process do you use?

It's not that hard to lift the pizza wheels on an 1800. If you set it up to print CD's, you'll see that the machine lifts them itself. I just jammed a piece of wire under each end of the bar that carries the pizza wheels so that it does not drop all the way back down. I also put a book on the output tray so the OHP does not droop as it comes out of the machine, as that can lift it enough inside the machine to hit the wheels again.
I get fewest scratches using the straight-through thick-paper path. That is a bit of a pain.

I use Agfa , tecco and folex and I change the % of inking for each of them. For sure it is easier to do with X800 epson model . But by calibrating the inking I have no problem with non sticking ink.
I use the same color for all these OHP and just lowered the % of inking till all the step of my 100 step tablet get out dry from the printer.

I have been using Canon Transparency clear film with my canon iPF5000 printer and LUCIA inks and in combination with PDN . LUCIA dries pretty quick on the TCF media. I get no smearing, tack sharp images with very smooth tonality in pt/pd prints . I actually had better result with this printer/ink on Canon TCF than with Pictorico OHP.

Something I have observed in printing with the Epson UC inks is that transmission density range is not the same on different substrates. Comparing Pictorico to the PhotoWarehouse OHP that I often use I have to add a +20 Ink to the settings to get the same DR with the PW OHP that I get with Pictorico. I am of course accounting for the difference in density of the substrate itself.

yes, removing the wheels is simple -- a few seconds -- but then TCF does not feed correctly and the tail end of the negatives get severely scratched.
Leaving larger borders solves the problem, just luck I am making small negs.
Arista and Pictorico feed just fine without the pizza wheels, probably because they have a greater caliper. TCF might be OK if I used cut sheets instead of cutting up a roll, as the camber is probably causing the problem. Slightly lifting the wheels with a spacer (easy) or removing all the wheels except the one on the ends (difficult) are other possible solutions.

In my experience the TCF boxed cut sheet film lays quite. I don't have an Epson, I use a Canon iPf5000.
