Web Services spontaneous turning off on Color LaserJet CM4540 MFP

Question

We are using ePrint on four seperate Color LaserJet CM4540 Multifunction printers in a business environment where we elected to activate ePrint in order to allow wireless printing for our iPhone and iPad users. We were able to set it up and get it working, and for the most part it works great! Users testing the functionality are using the HP ePrint for Home and Biz app and so far they've reported no loss of formatting for the documents they are printing - but there is one problem:
So far two of the printers have dropped (turned off) Web Services for no apparent reason.
Administrative functioning on the machines is password protected so it isn't possible for one of the clients to just come in and turn off Webservices. Only IT team members have the access password. I don't believe that any of us are turning off web services, so the impression is that they are spontaneously deactivating.
Two other bits of relevant information:
1) I am able to easily re-activate web services and assign a new eprint email address to the printer...
2)  I'm not able to reassign the first eprint email address to the printer because the HP ePrint website automatically places lost/disgarded email addresses on hold for 6 months to reduce the chance of people mistakenly sending documents to someone else's printer.
Therein lies the crux of the problem: because we are in a business user environment, every time I have to assign a new email address to the printer, I'm forced to update the documentation for the end users reflecting the addresses of the printers, and to inform the users who are already using the service of the new address.
I need to figure out a way to either 1) prevent the web service from shutting down, or 2) retain the same email address in the event that it does shut down, or both.
Any suggestions?

Hi Sumiko, With pleasure
Frankly, i am not familier with the secondary DHCP structure of the device as i am more focused on consumer products, however the logic still remains the same... As long as DHCP can be maintaned, i cannot see any reason why the static IP will fail as the connectivity remain the same, therefore i would recommend you to disable the secondary DHCP in order to avoid any firewall blocks after forwarding the ports.
The port forwarding should be assigned from the router or the server, depanding on your network structure.
If you are using a more complex network envoirnment by using any server, VPN, switch, etc. you will need to contact your IT administrator to configure the port forwarding
However if you are using a simpler network , please let me know the router model, i will gladly try to assist you locating the steps for your envoirnment.
