The "out of ink" light started flashing so I replaced the cartridges with new ones.
However, I still get the "out of ink" message even with new full cartridges.
I have tried with just the colour one installed, just the black one and with both.
Unfortunately I cannot find the manual and HP does not provide an on-line one so I don't know how to use any built in printer functions.
Seems a pity to throw away a perfectly good printer and to have wasted money on new ink cartridges. Anyone got any ideas?
