*1May vary depending on the environment and conditions under which the machine is being used.
*2Copy/print speeds are measured based on internal testing using A4 size paper copied/printed with 100% copy/print ratio to original on one-sided paper. Internal testing involved continuously copying/printing the same one page of content on plain paper (copy speed is tested by copying on the platen glass). Copy/print speeds may vary depending on paper type, paper size or paper feeding direction.
The device may automatically pause or slow down in order to adjust printer condition such as controlling temperature of a certain unit or limiting impact to image quality during continuous copying/printing.
*3May vary depending on the installation environment and paper to use.
*4The toner cartridges are not included.
