Hi - I assume from your post that you are able to make clean prints. I'm curious about how the mess of ink occurred.
I'm not clear on the status of the host computer. Are you up to date with Windows Service Packs? and have you reinstalled the most recent firmware/driver updates from HP?
I'm also wondering if the host computer sees the IP address of the printer. Can you ping it?
PS - one tip to consider, regardless of printer used: turn off the internal cutter when using any fine art/rag paper. Cut outside the printer with an appropriate tool, such as scissors. The dust created by the internal cutter can become a problem, whether Epson, Canon, or HP.
Thanks for the reply, Dave, especially the tip about the internal cutter with fine art paper.
I am using the latest driver, firmware and software available for the printer. My Windows XP is up to date with SP-3 and all of the upgrades associated with XP.
The computer can see the IP address, as I can ping it from my browser window. Oddly, some of the functions such as synchronizing the paper presets between the printer and the computer work, as does the information telling me how much ink is left, whether the heads or inks are out of warranty, and how much of what paper has been used. Yet other functions produce the message that indicates lack of communication between computer and printer.
As to how the ink buildup occurred I find it odd, because I am not a "heavy" user of the printer. I mostly print for my own exhibitions, with the occasional print job for friends. According to the printer's Accounting page (which somehow is accessible) I have used only 760 square feet of paper, which amounts to less than 4 100' rolls of 24" wide paper. This amount was in 19 months of operating the printer. A friend who uses the Z3100 in her printing business uses that much paper (and ink) in a couple of weeks and has not had this problem yet. I have kept up with the upgrades to firmware, software and driver.
