QR Codes and QuickHelp Pages
With many alerts or error messages, the printer includes the option to view a QuickHelp page from a
smartphone. When this option is available, the lower right-hand corner of the alert or error message
displays QR.
To access a QuickHelp page from an error message, do the following:
1. While the message is on the screen, press RIGHT SELECT to select QR.
The printer displays a QuickHelp page specific to that error message. This page includes a QR code,
such as this.
2. Scan the QR code with a smartphone.
Your phone accesses either a video specific to that error message or the Zebra support page for your
printer.
