I've used the iPF760 for 2+ months now. The machine itself has decent speed for an single roll inkjet plotter. It's easy to use and maintain. Changing plotter paper is easy and straightforward as well. Using the sheet fed option is simple too. The issue we seem to be having is with the quality of the prints which is easily the single most important part of the device. The prints come out very streaky on a very consistent basis. It seems that this device is really susceptible to having clogged print heads. Doing a print head "A" cleaning occasionally fixes this, but not regularly. Doing a print head "B" cleaning seems to help a bit more, but still does not solve the issue and consumes a bit more ink when executed. Doing a Nozzle Check print on a regular basis over the last two weeks has really helped to verify this issue. I have yet to get a 100% (or even 90%) complete print. I'm not sure if we've got a lemon or if there is a deeper issue here. We've been having to toss about 10-15% of our prints due to the unacceptable print quality we are seeing.
