Not sure what category this needs to go in or even if anyone can help.

I purchased a HP LaserJet Pro MFP M426fdw about a month ago.

It came with a starter toner, and yesterday it went out. So I went today an bought new toner and got the right toner 26A black toner.

But when I start on my work and started to 40 page packets the print would happen but continue to print on pages with ASCII, and would not stop. I have to force stop the print by unplugging it.

What could be causing this to happen?

I print PDF files.

I restarted my computer and printer and it keeps happen every time I print a packet. Could the new toner cartridge causing this?
