The WC 7556 goes offline at least two times every day and I must set online manually. It shows an error: 03-504-00 Machine is offline and will not accept new jobs submitted over the network.... It is very annoying. How I can set to "always online"? The firmware is the last one: 061.121.223.36000.
It could be corrupt software. Do a fresh alt boot software load. Make sure the cpu fan is turning it could be bad and causing the cpu to overheat.
If the CPU is overheating, it will show in section "Description & Alerts". Also the mashine is one years old and the counters shows 25893 pages is not too mach. But I will check that. Thank you.
The cpu fan is the one on the (sbc) single board controller. It isbehind the top rear cover and silver cover on the rear left held on by one screw. I would put the latest general release software on.
