my M2835DW goes to neverending sleep after a few days without printing. He also disappears from the device list on the WiFi-router. The I/O-switch still glows faintly blue, but I am unable to wake up the printer via WiFi (Win10, IOS, Android), a (permanently) USB-connected Win10-PC or even any buttons on the device. Pressing buttons only leads to a "virtual" start up with whirring and blinking lights, but the printer still won't print or show up in any device list and goes back to sleep after a minute. The only working remedy is to manually cut the power (pull the cord) and plug it in again. After that the printer shows up again on all devices.
I already accessed the webclient and enabled the "wake up event" (that normally seems to be the cure, following various threads on here), but to no avail. A few days without a printed page and the printer disappears.
I just had the idea to assign him a permanent IP (something I seemed to have forgotten) but that doesn't explain the behaviour on USB.

Is the firmware on this device up to date? Improvements and bug fixes are part of firmware updates and old firmware is one of the most common reasons we see for issues. Even if you just bought the product, chances are the firmware is a year old as devices are manufactured, boxed, shipped and sit in warehouses for months before being sold.
