I am really in need of a solution for fixing my printer. I have an HP OfficeJet 6600 that has been continuously flashing the common "There is a problem with your printer" error, which leads to a screen saying "printhead is not correctly installed or is missing." I need to finish printing nearly 300 photos within a week.
I used to be able to get around this error before - restart it a couple times and I'm good - but now I can't do anything about it. I have tried changing out multiple ink cartridges to no avail.
