Icmp failure the icmp test states failure and it was working fine a few hours ago

circuit board failure

Probably complete failure of the I/P dimmer

Malfunction of input circuit: voltage delivered is too low. The batteries may
be faulty or depleted. Wait for a few hours, leave the UPS switched on

If absence of input power (utility failure, maintenance work) is expected to last longer than a few hours, switch
off the UPS to save battery power. If the UPS input power is absent for several days and the UPS remains on
under no-load conditions, the batteries can be discharged very deeply, resulting in a short battery life time

Well maybe is is a power supply failure sometimes it doesn't warn you about a power supply failure so it might be that or the mem cart went bad on the system then.

a number of possibilities like insufficient pressure in the bell or pressure leak 'or pump motor dying
but i'd be looking at a warranty claim

Mine did the same a couple of days ago, I have taken in for repair, will get back once with details soon.

2 short, 1 long
BIOS checksum error
1 long, 2 short
Memory test failure (bad memory during memory sizing)

Blocking ICMP pings on a Zoom requires a few steps:

1) Go to Advanced Setup and select Advanced Firewall Filter.
2) Enable Advanced Firewall Filter.
3) Click on Security Policy Configuration.
4) Click on Policy Rules for "Add Firewall External-Internal Filter Rules."
5) Click on Add Policy Rule.
6) In the row labeled "Protocol," select "neq" and enter ICMP where it says "(Protocol Number or Name)."
7) In the row labeled "Select the direction to filter packets," select BOTH.
8) In the row labeled "Filter Action," select DENY.
9) Click on Save Changes and repeat 1) through 5).
10) In the row labeled "Protocol," select "eq" and "TCP." Below, select BOTH for direction, and ALLOW for filter action.
11) Save changes and repeat 1) through 5).
12) In the row labeled "Protocol," select "eq" and "UDP." Below, select BOTH for direction, and ALLOW for filter action.
13) Save changes.

That's it. Good luck!

Information gathered: Basically the printer carrier has stalled.
Lexmark documentation states that you should turn off your printer and wait a few seconds and turn the printer back on.
Restarting the spooler will sometimes do the trick as well.
Go to start, run
type: <cmd> without <>
Command prompt will open up.
Type: net stop spooler
The spooler will say it stopped successfully.
Type net start spooler
The spooler will say it started successfully.
Hope this helps!

Is there any change in the configuration made, like is ICMP blocked. If youa re bale to pass traffic without any issues and if the issue is just that you are not able to ping the HUB there is a posibility of blocking the ICMP requests.
