HI @anthia1,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Error 79 on your M234dwe printer can be quite frustrating, but there are a few troubleshooting steps you can try to resolve it:

Check Connections: Ensure all cables are securely connected between your printer and the power source, as well as any network or USB connections.

Update Firmware: Since you provided the firmware datecode, it seems like your printer's firmware is up to date. However, sometimes re-updating the firmware can help. You might want to check the manufacturer's website for any newer firmware versions or patches specifically addressing Error 79.

Reset the Printer: You've already tried powering off and unplugging the printer, which is a good first step. However, also try removing any additional accessories like extra memory or optional trays (if any), then power the printer back on.

Check for Paper Jams: Even if there's no visible jam, sometimes a tiny piece of paper or debris can cause issues. Open all accessible doors and carefully inspect for any obstructions.

Reset Printer Settings: Sometimes corrupted settings can lead to Error 79. Try resetting the printer to its factory defaults. This option is typically found within the printer's menu system.

I hope this helps.

Take care and have a good day.

I saw this solution in another thread that helped resolve the another user's 79 issue. You might want to try these steps :- 

1. Turn off the printer
2. Remove the toner cartridge from the printer
3. Wait for 30 seconds to 1 minute.
4. Turn on the printer again. Printer will show Er07 indicating missing cartridge. Now insert the toner cartridge. 
5. Error should go away and the printer is ready for printing.

Hi Anthia1 , 

Maybe you could try below steps and see if the issue could be resolved.  

• If possible, use ethernet connection. 
• If printer is connected with wireless, please follow below steps:
1. Turn off the printer, remove the toner cartridge from the printer, and then wait for 30 seconds.
2. Turn on the printer. After ER07 is shown on control panel, insert the toner cartridge.
3. The printer should go back to the Ready mode.
4. Press the Information button  to print the Printer Information Report. The report contains the printer IP address and printer PIN.
5. Open a web browser from computer/mobile device in same network, enter the printer IP address to access the EWS page.
6. Click Networking, and enter ‘admin’ as printer user name, printer PIN as password when pop window showing up. 
7. Go to Advanced at the left panel menu,  uncheck IPv6, and then click Apply at the right-bottom of the page.
8. Close the EWS page. The printer should recover now.
9. If Er79 occurs again, follow step 1-2 to recover the printer.
