I posted this before back in may. I have a MP780 that has the following simptons.
I have a new print head and new ink in the printer. When I perform a nozzle check the section at the top for the BCI-3 is not there at all, only the BCI-6 color sections are printed.
If I place a black and white document on the glass and tell it to copy in black, I get a blank page. If I place a color document on the glass and tell it to print in color it prints but the black is very faint.
Scanning an faxing work fine.
If I print a text document from the computer it comes out as a blank sheet. If I print a color document from the computer it prints the color, but no black.
I have tried the soaking and the windex, none of which seems to make a difference.
I have had several people suggest the purge unit. If this is a posibility how does one go about replacing it.
Any assistance would be appreciated
