dC976 Ink Delivery Fault Recovery
Purpose
To prime the umbilical assembly and check valve unit after replacement of the umbilical
assembly, check valve unit (CVU), attached to and included with the umbilical assembly.
Failure to prime the CVU and umbilical assembly may result in:
• Purge air pressure leaking backwards through the assembly.
• Ink bubbling up from the reservoir into the ink reservoir air manifold.
• Reservoir assembly replacement.
• Umbilical replacement, if ink enters the purge line.
After umbilical or ink melt reservoir replacement, purge line connections to the reservoir must
be physically verified. The correct orientation of the connections is shown in
REP 91.20 .
Procedure
1. Enter service mode, GP 1 .
2. Select the Maintenance tab.
3. Select dC976 Ink Delivery Fault Recovery.
4. Select the component that has been replaced:
• Lower Umbilical
• Upper Umbilical
• Ink Reservoir (This option has no benefit, use the other two options).
5. Select the start button to begin the procedure.
6. On completion of the procedure a message will be displayed of the success or failure.
NOTE: If a new umbilical has been installed then run the routine a second time. A single
priming routine may not be sufficient in all cases.
7. Select Close to return to the Maintenance routine window.
8. Select Call Closeout to exit service mode.
