Is it possible to fix Canon error code 5100 yourself, or should I call a technician?

For simple obstructions like paper jams or incorrectly seated cartridges, you can often fix Canon error code 5100 yourself. However, if the problem involves mechanical damage to internal components like the carriage belt or motor, or if you're uncomfortable opening the printer, it's safer and more effective to contact a qualified printer technician or Canon support.
