The reason for the mass hangs printer Kyocera?

In the enterprise after the new year began a massive hang printers (40pcs.) kyocera or come out of sleep, all work on the network without any print server.
Perhaps some spam on the network, but can't catch, help solve the problem.

Join subject and complement.
Disease affects models 1135 and 2035, the availability of the print server in the network does not have a role. Printers perfectly pingoud, but inaccessible through the web interface (the page gives a connection refused), the status of users is also "gray" is disabled. Tried
-disable all unused protocols in the printer settings
-turn off snmp v2 on the printer, the printer becomes online, but not print. Jobs up in the queue.
-change ip address, change network hardware.
Only after restarting the whole networking stack, the situation has improved until you restart the printer fell down a minute later after power on, after reset and at the moment the printers, you must restart one or two times a day.
Inclined to think that something generates the multicast storm, but not enough skill to wireshark to see the visible impact of the storm not the printers.
