Reissue
3-319 Finisher/Sorter Communication Failure RAP
The 3-319 Fault Code indicates a communication failure between the IOT PWB and the Fin-
isher PWB.
Initial Actions
Refer to BSD12.4 PWB Communications (Finisher) and to BSD 12.7, Monitoring, in this proce-
dure.
Procedure
PO/PO the machine. Fault Code 3-319 is still declared.
YN
If an intermittent is suspected, perform the following:
• Check the connections to the IOT CPU PWB and the Finisher PWB, and the inter-
connecting harness
•Reseat P/
J405 at t
he IOT CPU PWB, P/J1027, and P/J1026 at the Finisher PWB,
and P880, the Double Plug
Check for +5 VDC at P/J1026-3. +5
VDC is measured at P/J1026-2 on the Finisher PWB.
YN
Perform the following:
• Go to +5VDC Wire Nets and check for an open/short circuit
• Go to the +
5
VDC Power (IOT LVPS) RAP
Check for +24 VDC at P/J1026-1 on th
e Finisher PWB. +24 VDC is measured at P/J1026 -
4.
YN
Perform the following:
• Go to +24VDC-1 Wire Net and check for an open/short circuit
• Go to the +
24
VDC Power (IOT LVPS) RAP
Perform the following:
•Go to Flag
1 on BSD 12.4, and check the following wires for an open/short circuit:
– Check the wire between Mailbox Control PWB P/J1027-1
and IOT CPU PWB P/
J405-1
– Check the wire between Mailbox Control PWB P/J1027-2
and IOT CPU PWB P/
J405-2
– Check the wire between Mailbox Control PWB P/J1027-3
and IOT CPU PWB P/
J405-3
– Check the wire between Mailbox Control PWB P/J1027-4
and IOT CPU PWB P/
J405-4
• Replace the Finisher PWB (PL 18.4)
• Replace the IOT CPU PWB (PL 9.
