tion. The printer relies on this service for primary branch protection. If the printer is
without power, check the local supply voltage and verify that it is set correctly.
Example 2
Drops of Ink Appear on the Media
Check that the ink valves on top of the carriage are all open. If an ink valve is closed,
there is no vacuum pressure to hold the ink and it will drip out of the printhead.
Check that there is no hair or other debris on the underside of the carriage. Objects
can accumulate ink mist and result in small drops of ink.
If Problems Persist
If problems persist, perform the following actions as appropriate for the situation:
• Check for media that is buckling or sitting too high on the table.
• If you just changed ink in the printer, review the procedures in this manual and check
for successful installation.
• Try printing a test print.
• If the printer is not receiving print jobs, check the network cable connection.
Note:
If you still have problems, contact your Océ Display Graphics Systems service represen-
tative.
Call for Service
Try to eliminate simple problems before you call your service representative. However,
it is important to know when to call for service. Without training, servicing the printer
yourself may cause further damage. When you have determined that a service call is re-
quired, call as soon as possible. Have the following information ready:
Printer serial number — located near the AC power plug.
Error message displayed on the control panel, if any.
The exact circumstances when the error occurred, such as during printing, or mainte-
nance.
Note any unusual phenomena, such as peculiar printing, noises, and smells associated
with the failure.
