Ladybird I Folder March 2014 REPAIR ANALYSIS PROCEDURE
Service Manual 2-2
HOW TO READ THIS SECTION
This section provides information on how to understand the correct operation of input
sensors, motors, solenoids, clutches and troubleshoot and identify folder problems.
This section identifies typical folder messages.
•
STATUS Message : each time the folder is powered up the folder logic provides a Power
On Self Test (POST). This operation when completed (3 seconds) results in folder idle
condition ( no message or red LED indication or acoustic alert). The check verifies that
all sensors are clear (no paper present) and all interlocks are closed and all motors are in
the home position.
•
ERROR Message – during the fold process the folder logic monitors the paper path, if the
copy cannot complete a defined paper path section within a specified time, the folder
generates a fold error message. In this case, the CSE must evaluate and troubleshoot the
reason that the copy was able to start but not complete the specific paper path section.
User interface is provided by simple folder Control Panel with
some LED indicators and audible “beep”.
The folder after power cycle “POST” state a STATUS
MESSAGE
•
STATUS Message = RED LED FLASHIG 4 Beeps
every 30 sec.
The folder during the fold process may detect a paper jam, to
locate it, count number of beeps
ERROR Message = RED LED F Beeps every 30
sec.

SENSOR DEFAULT STATUS CHART
Since the folder has many sensors it’s important to identify the sensor
type : standard,
reflection, or barrier, LED indication and default LED status when uncovered and the relative
signal output voltage input to the Main Controller.
Sensor type: Case LED
a. Standard black red
b. Reflection pwb yellow
c. Barrier pwb green

In order to determine the folder sensor fault, remove all paper jams in the folder and switch
the folder off and on. After the POST, if the folder detects one or more sensor faults, the
folder will flash the Red LED on the UI and sound 4 Beeps.
In order to locate the folder faulty sensor, open the top and rear folder cover panel and see if
the corresponding LED on the sensor pwb is illuminated on ([C1C], [CC], [CT], [CA],
[CNF].or un-illuminated sensors ([C2], [C3], [CS])
When the fault is identified refer to the specific RAP for corrective action.
To determine if output motor are working press the selection key on the folder UI and hold ,
this will enable all the motor rotating in order to remove eventual paper jams and enable
CSE to detects if output are operating
