- The most common reason is an error with the printer itself. Check the alerts on the printer to detect low ink, paper jam, etc.
- Check the connector cables. The printer port adapter should display 2 lights: one on the top to show power, the one on the bottom to indicate USB connectivity. Contact KORR if adapter does not appear to be working.
- If you have recently replaced your printer, you may have an incompatible printer. Contact KORR for advice on purchasing an HP PCL 3 printer.
