Slack Loop Test Procedure - AGFA Avantra 36/44 Service Manual

5.14 Slack Loop Test Procedure

NOTE: The slack loop test works only for thin media (4 mil and
under). It is disabled for thick media (over 4 mil).
The slack loop test is used to determine the adjustment setting of the slack loop
flag as well as the speed of the bridge and take-up motors, based on the number
of times the slack loop is formed during a feed of a given length. The test is
performed as follows:
1. The slack loop test function is located on the Secret Screen of the Avantra
Control Panel. Press the proper key sequence on the "Configuration"
Screen to enter this special screen. Refer to Figure 5-6.
