[FONT=&quot]The dotted lines are as a result of residue edible ink from the pin feeds, which are used to help guide the sheets through the printer. You can see they are sharp ‘cogs’ of sorts, which lightly touch the frosting sheet as it prints. The marks are formed when the drying printer ink transfers onto the pin feeds, and back onto the white icing sheet.[/FONT]

Dreaded Epson pizza wheel issue. I've had some great printers that have suffered with this over the years. Only way to avoid is print at a lesser quality which to me is pointless. Pretty sure Ink Express sell the 7710 or similar so they may have a better idea than me.

So, are you changing over from 'edible' inks to 'sublimation' inks? I wouldn't have thought that was recommended!

I'd definitiely recommend a brand new clean printer for edible product ...
would you not also be better with a printer that boils the ink as part of the print process (i.e. a Canon and not an Epson)???

Epson best for Sublimation prints.

Hi Jevgenijs,

I'm guessing you used the printer with edible ink and fondant papers previously and are now using it for sublimation?

What type of paper and ink are you using, settings for printing, etc?

If the pin wheels have residual edible ink left on them this would be a simple fix of cleaning the pin rollers off with isopropyl alcohol.
The marks would also wear off after multiple prints, gradually getting lighter until they were gone.

Should the marks appear the same after many prints then it would more than likely be the paper and settings being used.

Again I'm guessing you are using a high release paper for the t-shirt transfers.
These don't allow the ink to dry quite as quickly as other papers.

If we have a printer with a particularly long drying time we tend to remove the high speed print setting, tick thick papers and envelopes, and see how the print comes out from there.

Let me know how you get on with these settings.

Run some blank sheets through inbetween prints as a last resort.
