Feed Clutch Boost
1903*
Adjusts the amount of extra push that the feed clutch gives to the paper after the
skew has been corrected at registration. This feature helps the registration roller
feed certain types of paper (such as thick paper). Increase the value if thick
paper is jamming after feeding from the registration roller.
