Hi there, how annoying, as with my last three hp printers, the hp envy 4500 as well is a big source of annoying trouble and a big waste of time and money.
Now the scanning doesn't work anymore - neither when commanded from the laptop-software nor when started at the printer itself. When asked to scan, it starts the scanning process by positioning the scanning-device, and opening the waiting bar, but then stops and doesn't move on - until I switch off the printer in the end.
The annoying thing: you seem to know the problem, that's why you have developped the scan-doctor - but that one runs only on windows, not on iOS. Annoying! What can I do to finally get the scanner working again?
Printing is not a problem, so it is obviously no connection problem. copying works as well, so obviously it is no hardware-problem either.
