Error B200 means the printhead voltage or temperature is not normal. The Printhead could be defective.... but first, try these solutions below:

Solution 1:
  • Disconnect the power cable from the printer.
  • Wait 1 hour.
  • Connect the power cable

Solution 2:
  • Check and Clean Head contact pin condition of the carriage unit
  • Check Cable connection especially the carriage FFC

Solution 3:
  • Turn off the power
  • Open the panel
  • Turn on the power
  • Wait for print carriage to start moving to the left.
  • Let it go past half way
  • Before print carriage reaches left hand side shut the cover.
  • Leave the Printer turned on

Solution 4:
  • Unplug the power cable.
  • Open the printer
  • Push the whole print head mechanic to the center
  • While the printer still open, plug the power and turn it ON.
  • When the printhead still moving and is going to the very LEFT, close the cover.
  • Wait until its boot up.

Solution 4a:
  • Take out all of the ink cartridges
  • Lift up the grey bar by where the ink goes
  • Left the print head in the middle of the printer all while the printer was off.

Solution 4b (thank you Jeremy):
  • Clean the plastic head primers/cleaners themselves on the printer (the far right)

  • Turn off the printer
  • Open the cover
  • Turn on the printer
  • Wait for print carriage to start moving to the left and let it go past half way
