Service Checks
Service checks involve measuring voltages of the LVPS, HVPS, and
RIP card assembly. Continuity and resistance verifications are done
on cables and components as required.
Note: When looking at the printed side of a PCB, connectors are
designated with “J” followed by a number. Pin #1 is designated on
the PCB by an adjacent “1” or triangle. Pin numbers index
sequentially to the opposite end of the connector. See
“RIP Card
Assembly” on page 5-8
for more information.
Cooling Fan Service Check
FRU
Action
Cooling Fan
Make sure the cooling fan motor
cable plug is properly seated.
Turn the printer off and disconnect
the cooling fan cable at the cooling
fan.
Turn the printer on. Within
approximately 15 seconds the RIP
card assembly should apply +24V dc
to the fan. See
“RIP Card
Assembly” on page 5-8
for more
information.
• If voltage is present, replace the
cooling fan.
• If voltage is not present,
disconnect the cable from the RIP
card (J22) and check for
continuity and shorts (connector
sockets #1 and #2).
– If the cable is good, see
the
“RIP Card Service
Check” on page 2-28
for more information.
– If the cable is damaged,
replace the cable.
