Possible Causes/Solutions
Replace the power cord.
Check wall outlet. Is it switch-controlled? If
machine is connected to a power strip, try con-
necting it to a known good wall outlet.
• LED 1701: Flashes fast. Indicates 5V pres-
ent at the PHC board which is sealed in
the print carriage assembly. (See figure
3-35 for main logic board.)
• LED 1702: "Heartbeat" lamp flashes once
per second. Indicates 5V present on the
main logic board and that the microproces-
sor is running.
Check for 27V (to feeder, transport motor, and
print head) and 5V (to control panel, main
logic). Check wiring to an connection at Main
Logic Board, J125.
Verify that all interlocks are closed. Power sup-
ply. Check wiring from PS board to Main Logic
Board, J126.
• If this occurs during install, check that all
shipping tape has been removed from unit.
• Unplug power cord from unit and then wall
outlet. Wait three minutes. Plug cord into
unit and then into machine. If this prob-
lem occurs every time machine is power
cycled, replace it.
• Check that ink cartridge cover is closed.
The system failed to detect the print carriage.
Check ribbon cable from print head to J127 on
Main Logic Board. Problem could be caused by
bad connection, ribbon cable, print head con-
troller board (sealed in carriage assembly) and
print head.
The system failed to detect the Postal Secu-
rity Device (PSD). Communications with PSD
failed. Is PSD present? Check that it is properly
seated and making full contact with board.
2304 is a communication timeout error.
Check sensor board and wiring to Main Logic
Board, J119.
