8.4 Remedial Action to Be Taken in the Event
of a Printing Failure
● If a printing failure occurs, perform the associated remedial procedures suggested
below.
● If the remedial procedures below do not achieve recovery, it is conceivable that the
problem is attributable to a PC board or circulation system failure. In such an
instance, contact your nearest local distributor.
