Hello.  When I am trying to copy a document on my all in one printer, it no longer copies.  I can click copy, choose the number of copies and black or color but when I go to click "ok" to copy, the "ok" button doesn't work.  Help!

@Kimmr130,

 

Welcome to the HP Support Community!

 

I recommend you follow the below steps and check if it helps.

 

1.With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

2.Remove USB cable, if present.

3.Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

4.Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.

5.Turn on the printer and wait till warm-up period finishes and the printer is idle.

 

If you continue facing the issue, I recommend you update the printer firmware following the steps in the below article.
