Question about HP DeskJet 5550 InkJet Printer
Upon opening the toolbox utility to check ink levels, calibrate, clean head, etc, the warning appears: Unexpected error has occurred (1001) Using a PowerMac G4 with OS10.4.11
I am also having this problem.
In my case it looks as if we need to clean the print heads but when I try anything with the print utilities it just gives me the "Unexpected Error 1001" routine.
My current theory is that switching to "Energy Saving Modes" might have a played a part.
Normally this mode could be turned off through the printer utilities ... but you guessed it ... when I try to turn it off I get "Unexpected Error 1001".
So two questions: a) if you are one of the people who has this problem have you set your printer into energy saver mode - where the printer turns itself off between jobs?
b) does anyone know of a way of setting the Deskjet 5550 back to factory settings other than through the print utilities software.

I had this problem as well. Replaced both ink cartridges (they were empty) and all is working fine now. No error messages.

I have exactly the same problem, only my Deskjet is HP 3840 and I am running a PowerMac G4 with OS 10.4.10.
