Something sounds broken and a call to HP may be required.
I read your post twice and it sounds as if you are trying to drive on some flat tire?
I was able to upgrade my 2000c for use with XP but now I don't get the tool box and it doesn't give me low ink warnings. (I have two screwed up cartridge switches) I no longer can reset the cartridges to allow printing. Hope to get the repair kit next month, but currently have jobs to print. HELP!
