Hello,
My H625CDW is set up on a wired network. When it goes into sleep mode, it goes into a sleep of death. While in this death (or maybe it's a coma), it will respond to pings, but it usually will not:
-Print from a network computer
-Respond to a Google Cloud Print
-The web gui management interface will not respond (typical port 80 web page)
A port scan of the printer IP reveals the following ports are open: 21, 23, 80, 139, 443, 515, 631, 8080, 9100
The printer has to be manually awakened to get out of this coma and even then it will not respond on the management web gui interface.
I have seen the support topic recommending setting up a static DHCP entry. I have already done that and it did not seem to have any effect, although it's possible it improved the response to print jobs. I even experimented with static ARP (the mapping between an IP address and a local MAC address) and this didn't help either. Regardless, the fact that this printer cannot maintain its own DHCP lease without coddling is disgusting to me. In 20 years I have never seen a device that required this kind of special snowflake treatment. Even my Nest thermostat, a battery device that scavenges power from my furnace only when the furnace is running and with real energy conservation concerns, knows how to check in and renew a DHCP lease on the appropriate interval. And here we have a mains powered, wired connection printer that can't handle these basics. Shameful, especially for something touted as a business product.
I am running the latest firmware as of today. I've been updating firmware religiously whenever a new one comes out. I've been experiencing this problem since I bought the printer.
I see other threads for similar issues with other printers and I find others coming to the same conclusion as me, but many of those threads ended without real resolution a year or two ago.
Has anyone got a solution for this issue?
