Solution for LaserJet pro M15w both attention and ready lights blinking

HP Recommended
Laserjet pro m15w
Microsoft Windows 10 (64-bit)

Anyone with this issue? If the Attention and Power lights are always blinking. You have checked for paper jams, unplugged and plugged the printer, you probably even tried to reinsert the toner and nothing hasn't changed.. I was in this situation two days ago! I did every tricks and try advice I could find online.. Nothing worked. I almost gave up and I was planning to buy a new printer.


This is what solved my problem:

1. While lights are flashing,  Unplug the power cord from the printer and wait for 30 seconds

2. Plug the power cord.The printer will still turn back on with the same lights flashing.

3. Leave those lights flashing (I left them flashing when I went to bed. The printer was turned off when I woke up. No more blinking lights. Nothing.  I pressed the power button to turn it on, BINGO!! Problem solved.)


HP says "this condition occurs when the printer is too hot to continue printing. To resume printing, wait for the printer to cool down." This is true.  When they say wait for the printer to cool down,  they are telling you to leave the printer PLUGGED IN until it cools down. Most of us would think that "cooling down" means unplugging the power for minutes or hours!! The longer you leave it unplugged, the worst. It cools down while plugged in and it will automatically turn off once cooled. Press the Power button, problem solved.


Hope it works for everyone. It worked for me.
