I've got a DELL A940 all in one printer and the ink was running low. Instead of buying new cartridges, I took them to a shop and got them refilled.
When I've re-installed these, no matter what I try in the very unhelpfull DELL manual, nothing works. It keeps ignoring the fact that the cartridges are now full and the printer says I've got an error (C50). I'v etried logging onto the DELL hel site without any luck
Can anyone offer any help.
