mx860 won't print in black

[Bubba888]

Hi,

I have a MX860 printer and just in the last few days it won't print in black.  I checked all my preference settings, did a deep nozzle clean, changed the large black print cartridge, did the test page and the black grid at the top didn't come in at all even though the rest of the colors did and did an alignment also.  I'm thinking it's the print head but thought I would ask before purchasing a new one.  Any help would greatly be appreciated.

Hi Bubba888,

If the black doesn't print after a few additional deep cleanings, you probably are dealing with a printhead issue.  I recommend contacting us for all your available service options.

Thanks for your speedy reply.  I did the deep cleaning three times in a row and it's working fine again.  Thanks!
