Factory"Calibration"of"1620"Gapsets"&"Field/Service"Fold"Roll"Replacement:"
1. The"proper"fold"roll"gapset"calibration"sequence"is"as"follows:"
"
a) #1"fold"roll"to"main"fold"roll"
b) #2"fold"roll"to"main"fold"roll"
c) #3"fold"roll"to"#2"fold"roll"
d) #4"fold"roll"to"#3"fold"roll"
e) #5"fold"roll"to"#4"fold"roll"
This"sequence"of"setting"the"fold"rolls"must"be"followed,"as"not"doing"so"may"result"in"improper"
calibration"of"the"fold"rolls"causing"inaccurate/crooked"folds."
2. Ensure"that"there"is"an"equal"gap"on"both"the"operator"and"nonHoperator"sides"between"all"fold"
rolls."This"gap"only"needs"to"be"large"enough"to"allow"a"single"sheet"thickness"of"20#"bond"pap er"
to"freely"be"slid"betw een "the "rolls."
"
H To"increase"the"gap"between"the"fold"rolls,"turn"the"gapset"knob"clockwise"
"
H To"decrease"the"gap"between"the"fold"rolls,"turn"the"gapset"kn ob "cou nte rHclockw ise."
"
3. Place"(1)"1”"wide"strip"of"20#"bond"paper"towards"the"outer"portion"of"the"main"and"#1"fold"rolls"
ensuring"that"the"paper"is"making"full"contact"with"the"urethane"bands"of"the"fold"rolls."

As"you"place"each"strip"of"paper"into"the"proper"fold"rolls"that"you"are"calibrating"the"gapsets"
for,"it"is"helpful"to"turn"the"ga p set"kn ob "co un terHclockwise"until"the"strip"of"paper"is"being"held"
