3. On the “User Defaults” screen, set the user feed length to 44".
4. Go to the “Utility” screen and execute a “User Feed”. The number of loops
appears in the lower right of the “User Feed” icon in the center of the
screen. When the feed is complete the number gets updated. This number
represents the number of slack loops completely formed (i.e. slack loop
formed and unformed).
5. The number of slack loops formed for a 44" feed should be at least 11. Per-
form several “User Feeds” to determine an average number of loops
formed. If the number is less than four, go to Step 6. If there are only four
to ten slack loops, the bridge speed parameters should be adjusted. Per-
form the following steps:
a. Using AVDIAG, download the “DEC Machine Parameters”. Select
“Image/Focus/Bridge” and locate the Bridge parameters.
b. Adjust the following parameters up or down accordingly, by steps of
approximately 50.
Ubr Fast Sp Thin - 4500 (nominal)
Ubr Slow Sp Thin - 6500 (nominal)
NOTE: Raising the number decreases the speed. Lowering the
number increases the speed.
