Hi, 

I have this issue with my printer that when I turn it on, the power button as well as the resume and wireless button immediatly start blinking, the control panel shows the letter E (see in picture). 

Can anyone help me please?

Hello,

I have not made any changes. It happened over night. I tried various button combinations, but nothing seemed to be working. The printer doesn’t even turn off when I press the power button once. I also tried the steps listed in the sent link, but it didn’t help.

Thanks!
