Hello Miss, I will advise you to load only 25 sheets inside the input tray. The quality of the paper also matters a lot so use only branded papers. Also, make sure there are no obstacles inside the input tray. This error may also occur due to dusty paper feed rollers, stuck print jobs, and improper spooler functioning.
