11.5 Separation pressure adjustment

Perform the separation pressure adjustment when the no feed (a paper is conveyed to the paper feed roller sec-
tion but stops there) or the double feed occurs at the paper feed.
Note
• Affected by the paper type and the operating environment (the no feed is likely in the low temper-
ature environment and the double feed is likely in the high temperature environment).
• Excess adjustment may reverse the symptom.
