Troubleshooting Sleep Issues Connected via Network

Sleep issues from a network connected printer are caused by the printer losing its DHCP lease. When the printer goes to sleep, it stops communicating with the network. This causes the DHCP Server to release the IP that the printer is using. The printer will not renew its DHCP lease until it is woken up (this will have to be done manually since the printer no longer has an open line of communication to the network).

To resolve this issue, set a DHCP reservation for the printer on the DHCP server or router. In order to do this, the printer will need to be set to DHCP mode for address assignment. Once the printer has obtained an IP through DHCP, access whatever device manages DHCP address assignment to create the lease. If using a static IP for their printer, you can reset the static IP to the same address as the DHCP reservation once the lease is in place (this is not necessary, however).
