This requires the IBC system to be in the stable bubble mode in order to be to be reported.  The FE-7 will report a misaligned web if either film edge sensor outer limit switch is on.  This can be occurred if the web is shifted to one side or if the outer limit switch is stuck.  If the sensor is tracking the film on both sides properly and this fault is occurring, it is likely that an outer limit switch is stuck.  Use the MBI CPU display to read the system states to determine which limit switch is stuck on.
