Hello, I bought HP LaserJet M15W in UK a few years ago, which it used 44A cartridges. However, now I moved to HK, which M15W uses 48A cartridges that I am only able to buy 44A cartridges here.
The HP website says M15W should be compatible with both. That’s why I purchases a 48A cartridge.
My printer keeps showing 'incompatible toner' after I tried to put in a 48A HP original cartridge and it doesn't allow me to print, and there is no way I can buy 44A cartridges in the HK.
I saw another post very similar to my issue and it was solved properly. Therefore, I would appreciate that you could let me know how to do NVRAM reset to let me use the printer properly?
Thank you very much for helping.

Hi @leungp,
Welcome to the HP Support Community.
I'd be happy to help you!
Since you moved to a different region, this unit needs a region reset. To get the reset done I recommend you contact phone support for more details.
For that to happen, we will give you additional instructions/information via Private Message.
Please check your inbox on the forums page for the private message.
Please mark this post as “Accepted Solution” if the issue is resolved and if you feel this reply was helpful click “Yes”.
