B200 generally indicates the print head has overheated or hit a voltage fault — it's a protective shutdown, not necessarily permanent damage.
Symptoms to look for
Printer displays 'B200' and stops all functions
Error appears mid-print job, often on a large or dense page
Error recurs immediately after every restart
What causes it
Printing very ink-dense pages back-to-back, a failing print head, or a short caused by a damaged cartridge contact are the typical triggers.
How to fix it
Turn off the printer and unplug it for 10 minutes to let the print head cool.
Remove all cartridges and inspect contacts for ink residue or damage.
Clean the cartridge and printer contacts with a dry, lint-free cloth.
Reinsert cartridges and power on normally (avoid pressing other buttons during boot).
If B200 returns within one print job, the print head itself likely needs replacement.
Technician's tip
B200 that clears after cooling but returns within a day usually means the print head is failing, not just overheating — worth a technician assessment before it fails completely.
