C4400 no longer working

[jangra]

I have been using non HP cartridges for years, and have learned to bypass the ‘incompatible cartridge notice’. Recently although the printer is connected and showing the options for  scanning copying etc, it no longer works, and attempts to do anything causes the ‘incompatible cartridge’ notice Any suggestions please?

I reviewed your post and I understand that you are getting incompatible ink cartridge error on the printer.

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

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, then follow the steps in the below article.
