VG540 Service Call 0400 [0001]

Hello WCSign,

The service call 0400 has to do with the ink being moved through the heads to the cap tops. The number after it refers to the head and channel or side of that head. We have seen that pouring cleaning solution into the cap tops then preforming a cleaning can create enough of a seal to get the ink moving again. We usually suggest that even if it does help a local tech is contacted as it could be a shifted flushing adjustment or a bad seal somewhere.

Thank you,
Roland Technical Support.
