Ok, so I am reaching out!
I have a Pro 100 and have just started getting the B200 error.
When I open the cover, the print head won't move.
The two buttons alternate flash white/yellow ten times.
It seems new print heads are very expensive, twice what I paid for the printer.
There is a used Pro 100 available locally for $100.
Hate to throw away my 100, not sure what to do next.
Thoughts?
