• Next, the vertical feed motor [not shown] on the left side of the machine turns ON.
• When the DRESS sensor [5] detects the leading edge, the motors and roll feed clutch turn OFF and
the machine checks for paper skew.
• Then the roll paper feed motor and roll feed clutch turn [3] ON and reverse feed.
• This process opens the nip between the roll feed roller and its idle roller.
• The registration roller [6] now has the paper and the vertical feed motor controls paper feed.
• The vertical feed motor feeds the paper to the registration standby position below the registration
roller [6].
• The roll paper feed motor reverse feeds with the clutch [3] off. This rotates the roll spool in reverse
to take up slack.
Roll Feed Mechanism
• When the roll paper feed motor [1] rotates forward, the feed roller [2] feeds the paper into the
machine.
• When the roll paper feed motor rotates in reverse with the roll feed clutch [3] OFF, the spool
reverses (for example, to take up slack).
