Is the Canon MP287 error B200 fixable, or is it time to replace the printer?

Whether the error is fixable depends on the root cause. If the print head is the issue, it can often be replaced. However, the cost of a new print head and the labor to install it (if you're not doing it yourself) can sometimes exceed the printer's value. If the motherboard is faulty, repair is usually not cost-effective. Therefore, assessing the repair cost is crucial before deciding on replacement.
