Usage recommendations

Use standard office paper for most jobs and a recommended toner cartridge specified by the manufacturer to maintain print quality and device longevity. Regularly clear the DADF rollers and keep the glass and scanning path free of dust to avoid artifacts in scans. For high-volume printing, monitor memory and job queue to avoid bottlenecks and consider scheduled maintenance following the manufacturer's service intervals.
