Product: HP DesignJet 500 42
Operating System: Microsoft Windows 10 (64-bit)
About 2 weeks ago our printer stopped working, it was showing the error I/O card not present. We've tried powering off and on, changing the slot, we have replaced the 615n with another one and also changed it for a 620n, all cards give the same error.
Any one have any ideas?
