No, I think he means to centre and tape a sheet of film on a piece of paper, before running it through the printer. That's what I used to do when I had the 4000. Never have had pizza wheel issues with the P400, unless I was laying down too much ink.
Sorry to be so dense about this. I can't visualize it. See attached image - do you mean something like this - transparency image taped onto a sheet of paper
I'll try to lay down less ink and see if that helps.
Choose Premium Glossy paper instead of Ultra Premium Glossy
And Choose Photo instead of Best Photo
Yes, that is correct!
Thanks.
Since you have a P400 printer would you mind sharing your print settings?
Understood.I use QTR driver. It overrides the printer's driver. It's far more superior.

Feed the transparency like a regular sheet. If that gives you a problem you might have to use a carrier/backing sheet (or some other gimmick to fool the printer.) But try the above first. It's too thin to be used in the Rear Fine art mode.

Sorry I couldn't be more helpful.

Yeah that's it. I apply small pieces of removable tape all around making sure none of them are sticking up - otherwise head strikes will happen. Some transparencies curl up quite a lot on the inkable side (that is another good way of finding the right side to print on) so it is imperative that they are taped sufficiently, also resulting in head strikes as a result otherwise. The backing sheet I use is a RC type smooth paper so the tape comes off easily after printing and same paper can be used over and over again.
Now for the pizza wheels, remove only the ones that would come in contact with the transparency (or the largest image width.) They are easy to take out, but I am not sure how they are to put back - so do it only if you are sure. I suspect your warranty will be voided too if you still have it.
Another way to do without taking out the pizza wheels is use the front feed. For that I use a thicker 4 ply cardboard as carrier instead. The whole pizza wheel assembly disengages in that case so none of them come in contact with the transparency. I used it this way until I started using QTR and found that QTR didn't allow the front feed option.
:Niranjan.
Note that @Andrew O'Neill is referring to digital negatives. You're now printing regular images for your transfer experiments. This means that his earlier comment about e.g. chartthrob is something to file away for the moment you get to printing negatives.
Not that QTR can't be used for regular prints - that's what it's intended for first and foremost. But I don't think you really need it to make decent prints with your printer on transparency materials. This is where Andy's other advice comes in: give the generic screen printing inkjet film a try. It's milky white stuff that's fairly cheap and can be had from (web) shops that specialize in screen printing materials. I've tried this as well as Fixxons and the main difference was that Fixxons was much more expensive. The Fixxons holds a tiny bit more ink, but the difference is so small as to be irrelevant in practice.
PS: Good job fixing much of the print quality issue so far; I agree with the others that the remaining few white dots are the dreaded 'pizza wheels'. I'm quite familiar with them as a fellow Epson user (3880 instead of P400 though). I hope @nmp's trick of using the different paper path works. I know some people go so far as to remove the wheels altogether. I'm not sure I'd recommend that.
Thanks. I’ll try the taping method. Not up for removing the wheels. Not sure how you position the film accurately for the print area on the paper. For example 8.5x11 on 11x17 (or 13x19)
Ive ver used the front feed but I could try that
what I don't understand is why and how using a better print quality setting which means more ink laid down, aggravates the pizza wheels. And, I've never noticed them on regular paper printsYeah it will take some trial and error...transparency will have to offset left to right since the wheels are not placed evenly and symmetrically and you will need to compensate the print position as well to reflect that - depending on which wheels you take out. But I too don't recommend it right now unless the problem is egregious. I suspect when you do the transfer, it probably won't matter. As for me I was using some serious ink densities (like 50% or more than standard) so I was getting pizza wheels galore. Even then my preferred way was to use the front feed, but QTR said otherwise. If you are not using QTR and still have unacceptable pizza wheels, that would be the way to go.
I don't recognize some of the terms you are using describe the options in printer driver - not sure if they different for Canadian version. Whatever they are, you should choose the parameters that slow the speed way down to lowest possible so the print has ample time to dry before it comes in contact with the wheels.

More ink density means that the ink lays in a thicker layer on the medium, making it easier for the pizza wheels to pick it up. It sticks to the pizza wheels better that way. This is exacerbated by the fact that a thicker layer of ink takes more time to dry, so it's more likely to be still wet as the pizza wheels hit the ink. This is also why increasing the pass time (allowing the ink more time to dry) often helps - at least a little.
The problem is more rate with regular paper prints because inkjet paper soaks up the ink much more readily due to its microporous, absorbent structure. As a result, by the time the pizza wheels hit the inked surface, the ink has already precipitated down into the top layer and doesn't stick to the pizza wheels anymore.
I’m not qualified to answer but Id think its not thick enough to be a support?As far as positioning is concerned, could you use pre-printed graphing paper as the carrier paper?

In the Print Quality > Quality Options, I choose Level 5, Print Quality = SuperPhoto, High Speed = unchecked.

Frank, see if you can download Epson Photo+ Tool. It gives greater control over B&W printing. My settings:Ahead of ordering Fixxons or Pictorico (or similar) I am using a locally sourced Grafix Clear Film for Inkjet.
Never having printed on anything but paper I'm new to this & trying to get down some very basic settings to print on clear film; prior to using process specific curves/Luts.
I printed a 21 step wedge & am seeing an awful "pattern" or "texture" plus what may be pizza wheel marks (quick phone photo attached).
Can anyone help identify the problem/s & hopefully suggest a fix.
