Show stop conditions
- There is a burning smell or visible ink leak
- The manual does not identify the printhead as user-removable
Likely causes
- The printhead overheated or developed an electrical fault
- Ink flow or a cartridge condition contributed to overheating
- The printhead contacts or carriage electronics are abnormal

Quick checks, in order
Turn the printer off and unplug it
Allow the printhead area to cool before any approved check.
Check cartridges and visible ink condition
Use only the model manual and avoid touching electrical contacts.
Perform only the official reseat procedure
Not every Canon model has a user-removable printhead.
Stop before board or printhead electrical testing
B200 often requires qualified service or replacement evaluation.
Does B200 return immediately?
A persistent printhead or control fault is likely.
Heat, ink flow, or an intermittent printhead condition may be involved.
Verify compatible cartridges and correct seating, then stop if the code remains.
Stop and get qualified help when
- There is a burning smell or visible ink leak
- The manual does not identify the printhead as user-removable
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
Can B200 be cleared by a hidden button sequence?
Temporary reset claims do not repair an overheating or electrical printhead fault. Use Canon’s model-specific guidance.
Does B200 always mean the whole printer is finished?
Not always, but printhead and board costs can make replacement the practical outcome on some models.
