Question about HP DesignJet 750c plus InkJet Printer
I opened back door toclear paper jam. now the switch says it is open
Ok make sure the back door is fully shut.by opening it again and closing it firmly. If that doesnt fix the problem then unplug the printer and let it sit unplugged for 3 minutes. That will reset it.
please mark this answer as a fixya!
