Hello Ed / Dottie,
Yep, all you said sounds right. Had a 24" 3100 and worked extremely well for almost 4 years, through personal use (nothing heavy). Something went wrong, and only then did I find out about having to scavenge parts here and there. HP was not stocking its own parts and I was even told by two "suppliers" that parts were no longer being manufactured (could not confirm that). What could be found seemed go up in price literally every 2 - 3 days !
To add insult to insult (!), HP's fee for coming to fix it was $1066, regardless of what was wrong, even if it turned out to be some $10 or 20 part !!
Was forced to sell it to someone who 'knew for sure' he could fix it, and he bought it under full disclosure on my part. Lost some $$, but I am more indignant than regretful.
I must say, though, that when working correctly, these printers are capable of producing truly excellent prints !
HP will NEVER AGAIN be on my list when considering printers, regardless of any "bargain prices" or technological advancement they may offer. A class lawsuit seems very appropriate in this case, as per HP's blatant disregard for its customers. To sell $3000 / 5000 printers and to "pull" all support / parts after barely 4 years is beyond belief; complete lack of conscience !!! Further, it is very strange how so many of these HP printers seem to 'go bad' just around the 4-year mark... At these prices, one would realistically expect to get 8-10 trouble-free years from these printers.
