Check3 Has the machine been printing continuously for a long period? If the machine has been printing continuously for a long time, the print head or other parts around it may overheat.

If the printing still does not resume, interrupt your print session at a convenient time and turn the machine off for at least 15 minutes. Caution • The print head and the surrounding area can become extremely hot inside the machine. Never touch the print head or nearby components. Check4 If copying stops before it is completed, try to copy again. If a certain time passes after some errors occurred while copying, the machine stops the operation. 612
