I had retired the Amped Wireless router I used to use with my previous ISP and put it in a cabinet. My modem, an Actiontec PK5001, came from Century Link, my local phone company, and is a combination modem and router. In the last year I had switched Internet Service Providers. But even that didn’t solve the problem.įinally, the HP rep said the problem was probably with my network, specifically with my router. After spending weeks on the phone and communicating through email with a patient HP tech representative, HP announced it could not duplicate the issue and sent me a refurbished HP8620, the upgraded version of my 8600.

Nobody seemed to have a solution, though there was indeed a solution at hand. I searched the Internet and discovered numerous other HP customers were faced with the same issue. When the printer slept, not even a sledgehammer would wake it up. Since the printer did not work properly with a wireless setup, I connected an Ethernet cable between it and the modem/router thinking certainly a hard-wired connection would make a difference. But it turns out there is no way to disable Sleep Mode. I thought I could solve this problem by disabling Sleep Mode. Then it would print until it went back to sleep. The only remedy, I discovered, was to power off the machine and then turn it back on. The front panel on the printer showed it clearly was connected. Every time I tried, I’d see an error message saying the printer was not connected, which was nonsense. The normal behavior for this and most other printers is that once you send another job to the device, the printer wakes up and prints. Suddenly I found that once the printer entered Sleep Mode, it would no longer accept any print jobs. And if you thought printers were among the simplest devices in the technology kingdom, you’re overly optimistic.įor nearly four years I’ve had an HP8600 all-in-one printer that worked fine. Despite what Apple wants us to believe, computers are not simple.
