Awful black letters Tags: Printers Canon Peripherals Last response: July 9, 2011 11:03 AM in Computer Peripherals Share zibizibi July 8, 2011 12:18:32 PM Hi, I've got a Canon MP640 ink since 10 months. Recently it started printing like this : I ran all cleaning/fixing programs available in the printer, I changed the 2 black cartridges (small and big ones), no result. What could cause this problem and how to fix it ? More about : awful black letters hang-the-9 July 8, 2011 4:05:33 PM Should be in warranty, replace it. Looks like the print heads are bad. zibizibi July 9, 2011 11:03:27 AM I had run the cleaning programs before changing the black cartridges. Then I printed this page. Now, I ran the cleaning program again and the printing is now OK. Weird o_O Can't find your answer ? Ask !
