HP DesignJet T730
Microsoft Windows 10 (64-bit)

Back in December 2020, I posted about a few problems we are having with our T730's.  I checked on another unit a user submitted a repair request for.  The description is streaking.  Streaking is putting it mildly.  There were several sheets with ink blots on them.  It appears this unit has the same problem as the other unit I looked at.  The printhead is leaking ink in a major way.  When I removed it, ink leaked on the floor.  It is literally dripping with ink.  At this point, my guess is I'll need a printhead and a service station for both units.  My guess is we ended up with at least a couple bad printheads.  I'm surprised there isn't a service bulletin for this problem and an extended warranty covering it.

Yes, we have seen a few leaking printhead, the trouble is most people do not report they simply replace the printhead. Other thing to watch for is that when this happens the line sensor gets covered in ink and you can have leading problems or aborted print jobs. Make sure you clean it while changing the service station. It is on the left side of the carriage.

Here to report the same problem. I call up support because my printer was under warranty and it seemed way too early for the print heads to go out considering our medium use. I was considering getting a new printhead, but I didn't even think about the service station.
