[Yejide8]

I have an error of 79 and nothing will work. It was saying attention needed for a month or so.

Hi Yejide8  , 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.  
10. If a factory reset or Wi-Fi network restore is done on the printer, follow steps 1-8 to resolve the issue if it happens again.
