Below is the text of a message I sent to Epson support regarding my R1800. It is very frustrating. As I sit here, I have it turned on (not trying to print anything), and it has gone through the process I describe below continually. It is currently on the Firewire, but it behaves exactly the same on USB. Any ideas would be appreciated. I have an XP machine and am using CS3.
"This printer is extremely unreliable. Typically, when turned on, the green light starts blinking rapidly and the print heads start thrashing back and forth. Then the printer will repeatedly lose and regain its USB connection with the computer (as indicated by the chimes that occur when USB connections are made and lost). Some times it actually turns itself off completely.
On the occasion when it settles down and I get a steady green light I will try to print an image. Typically it gets somewhere between 10% and 50% done, and then it ejects the unfinished print, the green light starts flashing rapidly, the USB connection is lost and regained, etc. etc.
On very rare occasions I am able to print an image, but the behavior described above can restart at any time.
My first thought was that there was something wrong with the USB port, so I tried several other USB ports, and nothing changed. It should be noted that I have absolutely no problems with other USB devices on this computer.
Then I thought it might be a problem with the USB hub, so I tried using the Firewire connection. The behavior of the printer was identical with the Firewire connection.
I have tried rebooting the computer, and that seems to make no reliable difference."
