1. Copying/printing speeds are measured based on internal testing using letter-sized paper, copied/printed with a 100% copy/print ratio to the original on single-sided paper. Internal testing involved continuous copying/printing of the same single-side content on plain paper (copying speed is tested by copying on the scanner glass). Copying/printing speeds may vary depending on paper type, paper size, or paper feed direction. The device may automatically pause or slow down to adjust printer conditions, such as controlling the temperature of specific parts or reducing image quality impact during continuous copying/printing.

2. May vary depending on output environment.

3. Based on 20 lb. bond paper.
