How do I clear a 'Service Error' on my Brother printer?

A 'Service Error' usually indicates a more serious hardware problem requiring professional attention. However, before contacting service, try a full power cycle (unplug for 60 seconds). Check for any obvious physical damage. Some models allow a reset through the printer's menu, but this is rare. Consult your printer's manual. If the error persists, contact Brother authorized service for repair, as it often indicates a failing component like the fuser or laser unit.
