Question about Canon PIXMA MP780 All-In-One InkJet Printer
We have been successfully using our copier all day. All of a sudden, a copy came out with lines missing. The area that had no ink on it at all was equal in size to that of college ruled lined paper. Coincidently, the last successful copy we made was of a paper on college lined paper. The copies since then have gotten progressively worse to the point of having almost no ink on the paper at all.
Also, the machine has started squeeking.
Try cleaning printhead (google it you find it) make sure you attempt cleaning with Windex ammonia D (overnight solution)
If not you may have to replace Printhead (Plastic Box, cartridges snap into) sometimes the resistor will burn out.
