Hi, I will be glad to help with the issue.
The B200 error is showing up due to a malfunctioned printhead.
Once thing you can try is to remove the ink cartridges,unplug the printer power for 10 minutes, plug back in, then re-insert the ink cartridges. If the error goes away, then the ink cartridges just needed to be re-seated.
Otherwise, the problem is due to the malfunctioned printhead and will require a replacement print head. Check first to see if you printer is under warranty that way it can re replaced. They cost about $50 and sometimes better to purchase a new printer for close to that price. If you would like to purchase the replacement print head you can get one here:
