3-319 MailBox Communication Failure RAP
The 3-319 Fault Code indicates a communication failure between the IOT PWB and the Mail-
Box PWB.
NOTE: If this machine has a Finisher/Sorter Accessory, go to Section 8D, 3-319 Finisher/
S
orter Communication Failure RAP to troubleshoot this Fault Code.
Initial Actions
Refer to BSD 3.4 PWB Communications (MailBox) and to BSD 3.12, 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 MailBox Control PWB, and the
int
erc
onnecting harness
•Reseat P/J405 at t
he IOT CPU PWB, P/J550 at the MailBox Control PWB, and
J880, the Double Plug
Go to Flag 1 BS
D 3.4, and check for +5 VDC at P/J569-1. +5 VDC is measured at P/J569-1
on the MailBox Control PWB.
YN
Perform the following:
•Go to Fl
ag
1 on BSD 3.4, and check for an open/short circuit
• Go to the +5
VDC Power (IOT LVPS) RAP
Go to Flag 1 on BS
D 3.4, and check for +24 VDC at P/J563-1 on the Mail box Control PWB.
+24 VDC is measured at P/J563
-1.
YN
Perform the following:
•Go to Fl
ag
1 on BSD 3.4, and check for an open/short circuit
• Go to the +24
VDC Power (IOT LVPS) RAP
Perform the following:
•Go to Flag
2 and Flag 3 on BSD 3.4, and check the following wires for an open/short cir-
cuit:
– Check the wire between Mailbox Control PWB P/J550-1
and IOT CPU PWB P/
J405-1
– Check the wire between Mailbox Control PWB P/J550-2
and IOT CPU PWB P/
J405-2
– Check the wire between Mailbox Control PWB P/J550-3
and IOT CPU PWB P/
J405-3
– Check the wire between Mailbox Control PWB P/J550-4
and IOT CPU PWB P/
J405-4
• Replace the MailBox Control PWB (PL 13
.10)
• Replace the IOT CPU PWB (PL 9.
2)
3-327 2nd DDI IOSS I/F Failure RAP
• 3-327 Fault Code indicates a communication failure between the IOT PWB and the DDI
IISS.
Initial Actions
Refer to BSD 16.1 Printer IDFE.
Procedure
Perform the following:
• PO/PO the machine
• Go to BSD 16.1 (Figu
re 1). Check the communications cables. Ensure that the cables are
seated properly and that there is no damage
• Reset the IOT CPU connectors and reseat the IOT NVM PWB.
• Reload IDFE System Software
•Go to GP
10 Replacing Billing PWBs and replace the IOT CPU PWB (PL 9.2)
• Replace the IDFE (PL 1
9.1)
