Onyx Go - UCJV300-160 not opening port 8002 — pings fine, RIP can't connect

[goldmanprinting]

Running a UCJV300-160 (firmware V3.4.0, MRL-V V1.50, Main PCB EPL5), 8-channel CMYK, LUS-170, into Onyx over the Mimaki TCP/IP method. Jobs fail — printer throws ERROR 206 PRINTING MODE.

Isolated it down to a direct PC-to-printer Cat6 cable, no switch/router, static IPs, WiFi off, REMOTE mode, no USB:

• Ping: succeeds, 0% loss
• Port 11110: open
• Port 11111: open
• Port 8002 (control): closed — Test-NetConnection returns False, confirmed with Windows Firewall fully off

So the printer is reachable and serving two of three Mimaki ports, but not listening on 8002. Already tried a full main-power cold boot.

Has anyone seen the UCJV300 stop opening port 8002 specifically? Is this a firmware/network-board fix, or a setting I'm missing? Mimaki just says "use RasterLink, we don't support Onyx."

I ran into pretty much the same issue when installing a Mimaki at a customer's the other day. Worked in Rasterlink but not Flexi. Same issue, could ping but not communicate. I'll keep an eye on this thread because we never figured it out. I've been setting up networked printers for 25 years and it's always a snap except for recent Mimaki installs. I think it's their driver but they won't ever admit that.

Exactly. Mimaki keeps showing me attitude, telling me to use USB cable and Rasterlink. Currently Onyx Support escalated this to their engineering team, we will se what they will come up with. I think most likely its because of mimaki driver as well.

The 330 series works fine on some aftermarket RIPs, but the 300 series is marginal at best. Basically, CMYK only and dodgy at that.
