Initial Issue
34,01X Ink Level Sense Faults
There are two known ways an Ink level sense over-range fault can occur. One fault condition
results from an internal short in the sensor or Printhead. In these cases, replacement of the
Printhead is required. A more common fault condition is caused by ink contamination. If differ-
ent color or type of inks mix in the reservoir, the sensor’s function is impaired producing the
over range fault. If multiple colors have mixed or the wrong type of ink has been used, remove
the source of the ink contamination, and then purge the Printhead.
NOTE:
The Ink level sensors can detect contamination before color mixing appears on prints.
WARNING
Allow adequate time for the system to cool before servicing the printer.
Initial Actions
•
Check the Ink Loader for improperly installed Ink Sticks.
•
Shutdown the printer and allow it to cool until the Ink solidifies (approximately 30 min-
utes).
•
Investigate where the contamination came from and remove the contamination source.
Primary Causes
The troubleshooting table lists parts and wiring referenced in the troubleshooting procedure.
Troubleshooting Procedure
Ink Contamination Faults
34,015.48

1
Check the Ink Loader chutes for improp-
erly installed Ink Sticks.
Has the Ink been loaded incorrectly or the
wrong ink used?
Go to Step 2.
Go to Step 7.
2
CAUTION
Do not attempt to remove ink from the
Printhead reservoir. Purge the reservoir
using solid color test prints as described.
Clear the Ink Loader of Ink. For these
types of errors, clear the Ink Loader of the
incorrect Ink.
1.
Remove the Ink Loader.
2.
Load the correct Ink into the chutes.
3.
Clean the area surrounding the Print-
head reservoir for the affected
color(s).
4.
Install the Ink Loader.
Has all the improper Ink been removed
from the Ink Loader and Printhead area?
Go to Step 3.
Continue cleaning
until no residual ink
remains in the Ink
Loader or area sur-
rounding the Print-
head.
3
Disable Ink Loader level sensing.
1.
Open the Ink Loader Door.
2.
Switch the power On and interrupt
the initialization process immedi-
ately after the Xerox logo is replaced
by the words “Warming Up” by hold-
ing down the
Up Arrow
button while
pressing the
OK
button.
If successful, the words “Level sense dis-
abled” momentarily appear on the display.
If these words don’t appear, power Off the
system and attempt the procedure again.
Ink level sensing remains disabled for
approximately 5 minutes.
Is level sense disabled?
Go to Step 4.
Continue Step 3 until
level sensing is dis-
abled.
4
Close the Ink Loader Door and allow the
system to reach “Ready”.
Is the system Ready?
Go to Step 5.
Go to Step 7.
5
Access the Service Tools menu to purge
the Printhead contamination using the Ink
Flush Prints routine. Select the affected
color to print 20 solid fill prints.
Were 20 solid fills printed?
Go to Step 6.
Continue printing
solid fills in the
affected color(s).
6
Check that the contamination has been
purged.
1.
Shutdown the system.
2.
Turn the system On.
Did the system reach “Ready” without
error?
Complete.
Go to Step 2 and
attempt a second
purge procedure. If
unsuccessful, go to
Step 7.
