Step Questions or Actions
3 Shutdown the system and wait 30 sec-
onds for the capacitors to discharge.
Connect I/O Board connector (P/J840).
Turn the system On.
Do the PE and PS indicators (near the
Power Switch) flash momentarily?
4 Check the 50 V Supply LED.
If the 50V LED (Figure 2) illuminates, the
short is on one of the external devices
unplugged earlier. In this case, systemati-
cally turn off the printer, plug a wiring har-
ness back in, and turn the printer on until
the 50V LED fails to illuminate.
Was the defective part isolated?
5 Shutdown the system and wait 30 sec-
onds for the capacitors to discharge.
Disconnect all connections to the I/O
Board.
Test the resistance of the I/O Board
across pin 1 of J270 and ground.
Pin 1 is on the left end of the jack.
Is the resistance still less than 1K ohm?
6 Reconnect connections on the I/O Board
until you find one that creates a short at
J270-1.
Does a short appear at J270-1?
7 Reconnect the Wave Amplifier.
Turn the system On.
Does the error persist?
8 Reconnect the Printhead.
Turn the system On.
Does the error persist?
