* If the value entered for this parameter is greater than 100, 100 must be subtracted from the value to
obtain the actual delay time. For example, if the value = 105, subtract 105 from 100 to determine the
delay time; i.e., 5 ms.
** If the bridge is in use, the value must be less than the BrdgeOffEly Time field, so that the bridge
shuts off, the nips open, and the feed motors stop.
***This field will only be in effect if the Extra Supply Feed in the Imagesetter Configuration Menu is
enabled.

Range Definitions
(0 - 255) Current for takeup cassette motor to move core to home
position.
(0 - 255) Torque of takeup cassette motor (Forward Direction).
The amount of time the nips are opened prior to stop-
ping the feed servos at the end of the feed, which aids
in preventing buckles and lifting of media on the drum.
Default is 1 (one). Increasing this value increases the
time.
(0 - 255) Delay of takeup cassette motor to start.
(0 - 255) The distance from the cutter to the top of the T/U cas-
sette core. This is so we know when to start turning the
T/U cassette core (Approx. 6 inches).
(0 - 255) Beginning of the range which the media is not supposed
to stop (6 inches).
(0 - 255) Defines the zone in which the leading edge of the
media is not supposed to stop (12 inches).
The media is allowed to coast to a stop to allow time to
check the optical sensors (i.e., the media present sen-
sors). Default is 10 (ten).
The starting point of the decelaration ramp of the take-
up servo motor. Default is 180. Enter 0 (zero) in this field
and 30 (thirty) in the NipsOpEly time field to disable the
ramp. Increasing this value makes the starting point of
the ramp earlier.
The amount of time that the reverse bump, which
reduces the media stiction to the drum, is in effect.
Default is 1 (one).
The reverse take-up servo motor current. Default is 30
(thirty). Increasing this value increases the torque.
The reverse take-up servo motor speed, which prevents
the supply servo motor from pulling the media up
against the shrouds while rewinding the media. Default
is 170.
in tenths of The amount of extra feed after an initial load. Default is
an inch 70, which equals 7inches. Increasing this value
increases the fed length.
(0 - 255) Delay of takeup nip roller motor to start running before
supply motor feed.
