Does B200 return immediately?

Immediately at power-on

A persistent printhead or control fault is likely.

After printing begins

Heat, ink flow, or an intermittent printhead condition may be involved.

After a cartridge change

Verify compatible cartridges and correct seating, then stop if the code remains.

Frequently asked questions

Can B200 be cleared by a hidden button sequence?

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.
