2. The “T-Compress Speed” is really the compression speed for both supply
and take-up servo motors. The supply servo uses a percentage of the “T-
Compress Curr” value. The percentage amount is specified in the “S Cmp
Curr Rtio” field, which has a default of 50 (50%). So if:
T-Compress Curr = 24
T-Compress Speed = 6
S Cmp Curr Rtio = 50
Then the take-up servo runs at a speed of 6 and a current of 24. The sup-
ply servo runs at a speed of 6 and a current of 12.
NOTE: The above values may be different depending on the revi-
sion of software in your system. Refer to the Customer Ser-
vice Bulletin (CSB) for the correct values for that revision of
software.
Write new values to the imagesetter by typing in the appropriate parameter. Listed
below are the media parameters, ranges and definitions.
Media Parameter Range Definitions
Supply Motor Feed Current (0 - 255) Current of supply motor during feed.
Supply Motor Comp Current (0 - 255) Current of supply motor during compression.
Supply Motor Comp Speed (0 - 255) Speed of supply motor when going into compression.
Supply Feed Speed (0 - 255) Speed of supply motor during feed.
Supply Hold Speed (0 - 255) Supply hold speed for punchless systems.
Supply Hold Current (0 - 255) Supply Hold Current for punchless systems.
Supply Rewind Current (0 - 255) Current of supply cassette motor during rewind.

The start-up delay time between the take-up servo and
supply servo motors. Default is 0 (zero), which indicates
that the delay time parameter is not being used.
Media Settle Delay (0 - 999) Settling time of media.
Nip Delay (0 - 100) Delay after Nips are open/closed.
Image Feed Length (0 - 3600) Image feed length from AVDIAG.
S-Spind Fwd Assist The supply spindle forward assist current, which is the
amount of current applied to the supply cassette revind
motors in the forward direction. Used at the beginning of
all supply and image feeds. Default is 50 (fifty)).
