I had this problem and the paper tray solution did not work. With having to get work done immediately I was in a bind. I then opened the ink cartridge cover, popped out, and replaced a cartridge. I then held the on button, plugged it in, and it was working. Very relieved.
Doesn’t turn on after standby. This seems to be a common problem on many printers of this series, but the solutions presented here are just a workaround. You have to go and unplug your printer each time you want to use it. Quite silly for a WiFi printer… I’ve dug a bit deeper; the problem lies in a supercapacitor 5,5V 0,22F on the main pcb motherboard. It’s unable to keep a charge and therefore the printer fails to come out of standby. You can get to the pcb by removing 9 screws, unplugging a few connectors and a bit of fiddling. Go in from the top, remove the scannerbed and work your way down. The supercap itself is a throughhole part that’s easily replaceable with a standard soldering iron and costs around €2. Good luck fixing this chinese piece of $@$* and getting your money’s worth out of it!!
I also had the problem where my hl l2380dw would not power on occasionally (same socket). Sometimes switching socket would work, sometimes not. Maybe it was more about unplugging it for a longer time? In any case, ran into this issue again, saw this post, pulled out the tray (not sure if this is important or not) unplugged for about 30 seconds (a little longer than I had tried previously), and then while pressing the power button re-plugged it in… it powered on immediately. Strange.
You can also try another method to overcome your problem. The following method is taken from Brother MFC-J4510DW Manualand i hope this will help you more effectively. Keep holding power button while plugging power cord back in and for another 60 seconds after, then release it. Make sure that there should not any damage or crack in printer wire. The proper voltage rate must be passed. The lithium battery inside printer should be recharged. If simple restart will not fix your issue, then move to hard reset.
This issue is now fixed for me. I started having this issue just after changing both the drum and the toner cartridge and updating the latest printer firmware for my HL-2280DW. I did not know which of these changes initiated the problem. The printer was showing offline on the network. It would remain in deep sleep, with its switch still ON. Switching the printer OFF, wait, then turning it back on, the printer comes back online, visible from the network, and restarted printing. The final step was to update the firmware of my router. After everything was up-to-date, the macOS bonjour connectivity is back. If I print while the printer is in deep sleep, it takes longer than before, but it eventually wakes up without needing special attention and starts printing again.
did the trick involving power button & plugging back the cord but it would always resort to shutting down mode so I had to l eave the lid open to bypass the error so that the printer would work again.
