My HP Envy 4512 All in One Printer has an error code

[1HotReel]

I turned on my printer this evening to copy a document. it did that successfully and then I tried to print something and received this error code -

0x00f81D42  TRKERNEL C

I tried power cycling the printer but the error code came right back. What should I do?

@1HotReel,

Welcome to the HP Forums!

Thank you for posting your query on this forum, it's a great place to find answers.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check whether the issue is resolved.

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 to face the issue, I recommend you update the printer firmware following the steps in the below article and test.

I seem to have gotten the error to clear, but now I have a new issue. 

My printer will print wirelessly from my phone, but not from my pc. Everything is connected to the same WIFI. Can you help troubleshoot this?
