5.5.10. ISSUE
: Empty Tray Error won’t go away
REASON / LOGIC :
Paper and clips have separate sets of sensors. Error
occurs when any of these sets of sensors are blocked or
out of line.
Root Cause Location Solution
Check for alignment of the
paper and clip sensors Align sensors to meet
Check sensor functionality Check sensors for malfunction –
replace as necessary
Check for wires and
connection to PCB
Sensors are located to
the left and right on
the tray inside the
machine
Reconnect any loose wires from
the PCB to the sensors.
5.5.11. ISSUE : No Power when power on
REASON / LOGIC : The beep from power on comes from the User Interface
panel.
Root Cause Location Solution
Check connection from PCB
to the user interface Remove bottom back
panel to get to main
PCB
Reconnect any loose wires on
the main PCB and try again. If
still unable to power up, check
filter for malfunction. If still not
working, replace PCB.
5.5.12. ISSUE : Element not detected
REASON / LOGIC : Element is detected through a pivoted trigger sensor.
Size recognition is based off the diameter OD of the
elements.
Root Cause Location Solution
Check element sensor
trigger for freedom to
rotate about its axis
If element sensor is stuck,
release it and replace if
damaged.
Check connection on the
PCB board as well as
transformer
Reconnect all wires if they are
loose.
Clip on the last element is
not pushed in all the way
Push the last element clip
tightly onto the element belt.
Check the screw holding
the trigger sensor to
ensure that it is tightly
held in place.
Remove the top panel
(8 screws). Looking
from the back, the
element trigger sensor
is located next to the
rail to your right
Tighten and apply loctitie on the
screw if its loose.
