Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

False colours When I try to print grey it comes out lime green. I went through all the cleaning steps. The colours bars show hardly any red, but my various cartridges all have plenty of ink and they are all snapped in place properly. Any diagonosis or suggestions? Thanks, Duncan in Canada.

Not being very familiar with this printer but if it has a calibration test/option I would run it and make sure it is set properly

My Xerox 8400 is printing the wrong colors. Where it's red, it's printing a brown shade and where it should be grey, it's printing green. My logo is grey and red and it's printing all grey, but not the...


Try printing a light stripes test page (Troubleshooting, print quality problems, troubleshooting print quality page).

If you do not appear to have many missing jets but the colours are all just wrong it may be that the ink has gone stale. Run a couple of head cleans and you should see the colours start to improve. If it is getting better, all you can do is keep running head cleans until you have replenished all the ink in the printhead well.

This problem is common in situations where a lot of black and white printing is done, with very little colour.
Alternatively, it could be that your wiper/cleaning blade is not cleaning the head properly and is smearing the different coloured inks across the head, or possibly that your printhead is leaking colours but I think the first solution should solve your problem.
Hope this helps.

Will only print photos in shades of green and grey.


Not being able to scan properly and improper colors are most often caused by glitches in the software. Try reinstalling your driver with a new updated driver for your machine.
Here is a link to the OEM page:http://www.kodak.com/global/en/service/downloads/dln_ekn033540.jhtml?pq-path=9106

This is the all in one driver. Install this and try again and it should fix it. Let me know if it helps.

Print text is grey not black


Have you tried cleaning the laser? Open the front door, on the R/H side there is a green lever, pull this forwards. Next on the R/H side of the printer pull off the small panel, inside is a green handle. Pull this in & out fully a couple of times to clean the laser lens. Hopefully your prints will now be back to normal. If not then there could be a problem with eitherthe black developer or the PCU. Try printing some horizontal coloured bars to see if all of the colours are affected or just the black.
