*1 May vary depending on the environment and conditions under which the machine is being used.

*2 Depending on the situations, the machine does not startup quickly.

*3 Print speed is measured based on internal testing using LTR/A4 size paper printed with 100% print ratio to original on one-sided paper. Internal testing involved continuously printing the same one page of content on plain paper. Print speed 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 printing.

*4 May vary depending on the installation environment and paper to use.
