Ink carts are all full. Test print is pretty ordinary and no colours are
printed. I assume the print heads are gummed up. Any tricks on how to clean
them? Any tricks on how to pull this sucker apart would also be appreciated.
The service manual is not much help.

Same problem with an i865. Any tips for that one too?

TIA

I managed to strip the MP780 apart. How do I clean the print heads? I have
not removed the ink carrier yet. That appears to be a very significant job.

TIA

**Thanks for that. I actually needed to know how to extract the print head.
I finally worked that out and cleaned it. I only need to sort out a few more
issues and I should be able to get it working.
