I have an Epson 820 and it periodically loses communications with my computer during printing (highest print quality, full color). It reconnects after being turned off and then on again, but I lose whatever is currently printing. It's very frustrating and wastes paper. I've even purchased a new, higher grade USB cable and connect directly to one of my computers USB ports.
I've had the printer for about a year and only noticed this happening within the last couple of months.
Have others experienced this? Any ideas or solutions?
It's possible that your computer's USB ports have flaky drivers or some other problem, perhaps a corrupted file is to blame. You might check for bios updates for your computer or any USB related updates. Since the problem hasn't hit you until recently, I'd troubleshoot drivers before getting into hardware diagnostics. Try uninstalling the printer driver and reinstalling it. Check the Epson site for a driver update before you start.
One hardware thought, however. Have you added a new USB device that perhaps coincides with the occurence of the printer problems? Some devices and/or their drivers can cause USB problems for other devices.
...first connecting your printer USB cable directly to one of your computer USB ports. Going through a USB hub usually works, but can occasionally cause strange problems. If this does not solve your problem, you should uninstall your printer completely, and re-install fresh drivers (including the Epson ink monitor) downloaded from the Epson web site. Make sure you install these drivers and not the "generic" Windows driver for the Epson printer, which is much less capable. Windows will try to install the generic driver if you let it do its thing automatically.
Finishing a half-page of printing and then freezing up is a frequent symptom of the installation of inappropriate or older Epson print drivers. You've got to replace both the print driver and the ink monitor to solve the problem. (Or else remove the ink monitor altogether, which I don't recommend.) While you're at it, you can download printer output profiles for ColorLife and perhaps other papers.
Thanks for the suggestions. I downloaded the current driver and I'll see how that goes. I'd already bypassed the USB hub. I may need to go back to my original driver since I did download an upgrade awhile ago. I can't remember if my problems started with the new driver or not, but if I continue to have the problem I'll try going backwards.
...the driver and ink monitor software. The latest Epson drivers from Epson have always worked for me. Make sure you get the WinXP (may actually be Win2000) drivers, and ignore the dire warning during installation about the drivers not being tested with WinXP, if applicable.
The first thing to check isn't your USB hub but rather your hard drive. In order to spool that big of a file, it takes a lot of space. Your spool file directory is almost certainly on your C: drive. You should have *at least* a couple hundred MB free space on it.
I had a similar same problem with my 785epx. The drive generated a "no commuinications" dialogue box in Windows XP. Being poretty sure it was not a mechanical problem (all connextions direct and firm (no hub)) and having all the latest drivers, I finally just ignored the warning screen and printed anyway. It worked. After a while I could could close the no connection dialogue box. I thinks its amtter of spooling and the speed with which the driver fills the spool. In any event its an annoyance that happens to me once in a while.
