Today, we measured and found out that when the printer wakes up, it takes 5 mins to go to sleep (this is a printer configuration param), then, exactly after 15 minutes, the printer wakes up again. I do not understand why every 15 minutes the printer wakes up for no reason.
We have a brand-new (1 day old) MFP6121/N in the office, connected to a linksys/cisco router via ethernet.
When we do not print/fax/copy/scan anything for a while, the printer goes to sleep mode. However, even if we do not print anything, every once in a while, the printer wakes up, warms up, and after warming up, waits for a few minutes and goes back to sleep.
Any ideas? we do not want the printer to wake up unnecessarily.
