GxT Ferret 54 ENGINE DIAGNOSTIC CENTER - Manual (Page 96)

PRINTER WARNING MESSAGE
The cause of the printer message is
generally a paper jam, causing the print head
to move too slowly or not at all.
Pulling paper backwards is not
recommended because it can cause wear on
the paper advance mechanism. However, in
the case of a paper jam it may be necessary
to pull the paper backwards. Remove
jammed paper slowly to minimize tearing,
and to remove pieces that are as large as
possible. Paper that is exposed at the tear
bar should be slowly removed by pulling in
the forward direction.
It may be necessary to use tweezers to
remove paper that is jammed to either side
by the print head.
Make a square cut across the leading edge
of the paper roll and insert it into the paper
inlet. Press the Paper Advance button in the
printer compartment to advance the
mechanism. The paper should feed through
easily.
If the problem can not be resolved, contact
the factory for assistance.

TEST LEAD CHECKS
Many of the test leads can be checked
using built-in system diagnostics found
in the
Diagnostic Center Setup menu.
Select the desired test and follow the screen
instructions.
Cylinder #1 Pickup Check
Refer to the diagram below while following
the on-screen instructions.
ELECTRICAL INTERFERENCE
Electrical interference, if significant, may
cause the Diagnostic Center to reset
unexpectedly. Common sources are:
• Intermittent battery connections
• Arcs in secondary circuit caused by
broken sparkplug wire insulation or dirt,
that can allow sparks to track along the
outside of a wire.
• Metallic (nonresistance) wires radiate
radio interference that, if severe, can
disrupt operation. Replacing the coil to
distributor wire with a resistive wire while
testing can help.
• Pass the Coil (-) lead through the
Cylinder #1 pickup four times, so that
the lead comes out the side labeled
"Spark Plug".
• Close the pickup jaw.
• Use a short length of stiff wire with the
multipurpose clip to probe Pin 2 of the Oil
Temperature Socket. This is most easily
done through the extension lead.
