I just purchased an brand new Epson 3880 which I will convert to piezography as soon as my inks arrive (I am waiting excited as a little child).
I have been testing it to see if there was any problems with it, and everything seems to be good in terms of nozzle checks, etc. My favourite paper is harman gloss baryta - which is a very fragile and delicate paper, which bends and twists a lot. Giving the fact that I will have to send this printer through the printer two times (due to GO) I have been experimenting with ways to handle the paper in the best possible way - and it seems to me the only way that works with this paper without scratching it or embedding some pizza wheels into its delicate surface is using the front manual feed. And when I use this feed it does produce gorgeous scratch free prints. What I do is I use a heavy weight paper as a backing board to my sheet of harman gloss baryta and feed it through the manual front feed.
But I have been noticing this strange "cloud" of black dots on one side of the print (in the white border around the print itself). I have attached a photograph that shows this cloud - which I observer severa places on one side of the print in the white border. I have also attached a photograph showing how the print exits the printer - it seems that it is only in the side closes to the right most side of the printer that is affected - I get these clouds around three places on the print. I have printed the same print twice and the clouds forms exactly the three same places.
I have tried printing color prints using the OEM Epson print driver and black and white prints as well using the Quadtone RIP driver as well - I have observed these clouds using both methods but only using the manual front feed. Anyone has any ideas what could cause these clouds of dots?
FYI my platen gap is standard. No high speed printing involved - don't know if that makes a difference?
