If a problem continues after reviewing operator adjustments, request support
from a Customer Service Engineer. Use the following guidelines to aid in
determining what is wrong and what may need to be done.
Determine which subsystem of the M-40 exhibits the problem. The alarm
messages displayed on the M-40 operator interface indicate to the operator
which subsystem is affected:

Feeder

Folder

Glue System

Stacking Conveyor
C.6a Feeder Alarms
DBL FEED
First, ensure that the sensors are not dusty and are adjusted properly,
especially the double detect sensor.
If this alarm occurs and two pages were actually fed :

Singulator roller is too high

Auxiliary feed belts are too high

Double detect sensor is too high

Paper hopper is not positioned properly
Any one of these areas could be out of adjustment, or a combination of
adjustments could be incorrect. Refer to Section D of this manual for correct
adjustment/s.
FEED ALARM
If this alarm displays and no paper was fed from the feeder:

Singulator roller is too tight

Paper hopper demand switch is too low

Paper hopper is not positioned properly
Note: If the display indicates either of the above messages and one page was
fed, then the problem may require technical expertise beyond the scope of the
operator. Outside intervention by a qualified experienced technician.
