Copy a brightly colored paper towel in color , it prints fine
The 3rd MX860 will not turn on at all.
Replaced power supply with a known good power supply, no difference.
tested the original power supply in the 1st MX860. works fine.
put power supplies back in their original unit.
The 3rd MX860 will just not turn on.
Looking for suggestions as to what to try next.
if that means replacing the logic board point me to where to purchase the logic board.
If I cannot repair this MX860, I need to know what Canon Printers use the same ink cartridges.
I have far too much money tied up in ink cartridges to just not use them.
For a listing of printers that use the same inks as the PIXMA MX860, please click here. Please note, we do not have any current model printers that use the same inks as the PIXMA MX860.
For the PIXMA MX860 that is not printing black, when the nozzle check pattern printed, if a black grid resembling a net did not appear above the colors (in addition to the black color that appears in the color section), we recommend performing at least one cleaning and two deep cleanings to try and resolve the issue. To do this, please follow the steps located here.
For the PIXMA MX860 that will not power on, if you have another power cord you can use with the printer, please see if using that power cord will allow the printer to power on.
If the printers still do not turn on or print black ink after performing the above steps, they will require servicing to determine the exact cause and resolution to the issues. Please call or email us at one of the methods on the Contact Us page to obtain your servicing options.
