I don't have experience to share...yet. But I can tell you the main printers in the 44" category to consider. We recently went through this exact same thing. Unless you have mega $$ for a > 44" Mutoh these are your options if you go the new route (there are also older printers if you want to go that way). The top contenders for us were the Epson F6070, Epson T7000, Epson 9890, Epson 7890 and Mutoh RJ-900x. We also looked at the Epson 9890 & 9800 but they were ruled out because of speed, and the 9700 which was ruled out to the large number of posts I read on here about issues. In the end it came to a coin flip between the F6070 and the T7000. The T7000 with conversion to J-Teck sublim inks being about $1500 cheaper than the F6070 for most people. In the end, we ended up deciding on an Epson SureColor F6070 because of the year warranty and deal we got on it at a show.I am looking to upgrade from a Ricoh SG3110 to a wide format printer. Any suggestions?
If you're looking at hacking a wide format and doing sublimation with it, I would suggest talking to Daniel @ Digitally Driven. He was recommended to us by others on this forum. He's very knowledgeable and should be able to help you with the conversion.
