Trying to change cartridge for the first time on this HP 6055, purchased < 1 year ago.
Cannot lift the scanner/top to access the cartridges, lifting from handles on the side. Yellow light comes on and an "uh-oh" tone is heard.
Using all the techniques found in the Archive here as suggested MULTIPLE times by the HP techs. (Unplug, plug in , etc etc).
When I turn on the printer each of the MULTIPLE times I have unplugged and plugged it in it sounds as if cartridges are moving.
I bought an HP because I thought it was a good brand. Obviously this is a common defect and needs to be resolved.
Less than a year and now I'm thinking that $150 just went down the drain. Maybe it's covered by a warranty, but that just seems like a hassle. I'm really disappointed.
