Just stumbled upon the cause of the problem. I went to print something in colour and it only printed black and white, printer didn't seem to realize the colour cartridge was empty or malfunctioning, I didn't know that installing a black cartridge required a test page printed in colour (who would?), and of course the software wasn't able to recognize this fault and simply rejected the test page altogether. Now that I have installed a new colour cartridge and scanned that (all of a sudden it scanned it happily), it seems to work now. HP needs to work on the software for these things, probably losing a lot of frustrated customers because of simple little software deficiencies.
sometimes when you insert re-manufactured ink cartridges into your printer this problem arises. i installed <a href="click here">printer ink cartridges</a> but cleaned the brush heads and the problem was sorted
