That may be true with Epson printers that have been well used John, but mine was never a production machine. It would often sit for weeks without being run. In fact, I did a status check before taking it in to the repair shop back in November and all items listed on the status report indicated three out of five stars (apart from the waste ink container that showed two stars). The printer never exhibited a banding problem I couldn't resolve with several head alignment printouts right up to the time I lost the light black nozzle.
This issue is an illustration of the gross incompetence of the two technicians who came out to repair the printer as their alignment tests were always off by a wide margin after they left. The second technician, after working on the printer for six hours, brought a print out of the studio and had a big smile on his face. He said "I think you'll be happy with this."
I took the print and brought it into the kitchen where there were bright ceiling spot lights that were ideal for checking banding. Before I even entered the kitchen and before putting on my reading glasses I could see obvious banding. I offered these clowns the use of my 4X, 8X and 10X loupes as they clearly had poor vision. They were constantly entering the wrong numbers when evaluating their alignment printouts so the likelihood of them getting proper alignment was nil.
Most upsetting was that the second technician wrote in his reports that there was no visible banding when he admitted in my presence that there clearly was visible banding but that he couldn't resolve the issue. It doesn't get any worse than this. Epson should rethink their policy of contracting out to these cash register repairmen as they are clearly under qualified to work on wide format printers.
What happens with these old Epson printers that have been well used is that the carriage itself wears out. The grooves that the head unit travels on become worn down, and the head becomes wobbly, and you see micro banding, eventually at all resolutions. You could put a million heads on it and it wouldn't make any difference. There are probably some very good technicians working for Decision One, but my experience with them was pretty scary. The guy said he works on all kinds of equipment but had never worked on an Epson before. He was on the phone with someone who told him what to do. My problem wasn't resolved either. But I just gave up. They really want you to trash these older printers and not keep them going. Its always been like that. I'll bet HP is the same way though.
