Status Indicator RAPs
93-545-00 to 93-548-00 Ink Melt Conductivity Error RAP
93-545-00 The black melt reservoir ink conductivity is out of usable range.
93-546-00 The magenta melt reservoir ink conductivity is out of usable range.
93-547-00 The cyan melt reservoir ink conductivity is out of usable range.
93-548-00 The yellow melt reservoir conductivity is out of usable range.
Initial Actions
• Check for ink stick jams.
• Check for non Xerox ink sticks and report as appropriate.
• Check for wrong colour ink sticks loaded.
• Check that the ink sticks are in contact with the melt plate.
• Check that the tips of the melt plates are the correct colour.
• Check for reservoir contamination from ink shards getting into the incorrect colour reser-
voir.
• Check the ink melt plate for damage may cause melt ink to enter the incorrect colour res-
ervoir.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Check that the ink reservoir, PL 93.10 Item 10 is in good condition with no ink overflow. Check
for damage that may cause the reservoir to leak. The reservoir is good.
Y
N
Check that the umbilical clamp fasteners are tight, refer to
REP 91.31 . If the fasteners are
loose, clean the area, then firmly tighten the fasteners. If necessary, install a new ink res-
ervoir,
PL 93.10 Item 10 .
Go to WD 9.9 and WD 9.16 . Check the wiring between the ink level sensors, the solenoid
patch PWB and the marking unit driver PWB.
Refer to:
• P/J101, Marking Unit Driver PWB .
• PJ380, PJ 760, PJ780 Solenoid Patch PWB .
• 01B +3.3V ESTAR Distribution RAP.
• 01L 0V Distribution RAP
Install new components as necessary.
• Ink reservoir, PL 93.10 Item 10 .
• Ink level sensor cable (Ribbon cable), PL 93.10 Item 18 .
• Marking unit driver PWB, PL 92.10 Item 4 .

93-549-00 Head 1 black reservoir did not fill within the correct time.
93-550-00 Head 1 magenta reservoir did not fill within the correct time.
93-551-00 Head 1 cyan reservoir did not fill within the correct time.
93-552-00 Head 1 yellow reservoir did not fill within the correct time.
93-557-00 Head 3 black reservoir did not fill within the correct time.
93-558-00 Head 3 magenta reservoir did not fill within the correct time.
93-559-00 Head 3 cyan reservoir did not fill within the correct time.
93-560-00 Head 3 yellow reservoir did not fill within the correct time.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
CAUTION
Do not remove the solenoid patch PWB, PL 93.10 Item 9 .
NOTE: If the printhead reservoirs do not fill, it can cause massive jet loss. If necessary, refer to
the
IQ 9 Deletions in the Process Direction RAP.
Move the marking unit into the service position, GP 6 . Check that the air channels from ink res-
ervoir solenoids 5, 7, 11, 12, 15, 16, 17, and 19 is free of ink, Figure 1 .
If the ink has blocked the air channels then install a new umbilical and ink reservoir at the same
time. Failure to replace both units will cause another ink reservoir failure.
NOTE: Some ink discolouration of the air channels is normal.
The channels are free of ink.
Y
N
Install a new lower umbilical,
PL 91.25 Item 10 and new ink reservoir, PL 93.10 Item 10 .
Check that the print heads, drum and waste tray are clean, without excessive ink contamina-
tion.
NOTE: Excessive ink contamination will be obvious.
The print heads, drum and waste tray are clean.
Y
N
The print area is contaminated with excessive ink. The purge line is blocked. Perform the
steps that follow:
•
GP 27 Cleaning Procedure.
• Install a new purge line filter, PL 91.25 Item 9 .
