Additional Information

A note regarding printer setup and configuration 

The GX-Series printer can be configured by your driver, host application, or a utility. In these examples we will use the Zebra Designer Driver to configure the printer. (The configurations are sent when printing using the driver or printing the driver test page) If you are using a non-Zebra application/driver/label software determine the methods used to set these configurations and be aware the terminology for each setting in your environment may be different. 

1. Understanding your media

The Zebra Printer supports the use of many types and shapes of label/tags and knowing your media detail is important for proper configuration.

Here are the details you should know for printer media setup and configuration. For our examples we are using the ZebraDesigner Driver to show the configuration selections for each topic discussed below.  Note: When using the ZebraDesigner Driver the configurations are sent to the printer when you request to print a label. (i.e. printing the Windows Test page will send the printer configurations)

Media Related Configurations

>Media Type (Tracking Mode) - Selections - Continuous, Web Sensing (gap), and Mark Sensing (Black Mark). Default is Web Sensing 

ZebraDesigner Driver (Printing Preferences - Advanced Setup - Tracking Mode) Read More>>

If you are using media with an inter-label gap or a center hole set the Tracking Mode for Web Sensing.
If you are using media with a black bar or mark set the Tracking Mode for Mark Sensing.

>Print Method (Media Type) - Selections - Thermal Transfer (Using Ribbon) or Direct Thermal (No Ribbon) – Default - Thermal Transfer

>Print Mode - Selections-  Tear off, or Dispense Mode (Peel)  – Default is Tear off  

This is related to the label presentation after printing and limited to the options you have installed. The GT800 Printer  supports Tear Off and Peel (Dispense Option Required).  Read More>>

>Media Loading - The media must be properly loaded for the Print Mode you intend to use.

2. Understanding the Media Sensors

The printer comes with sensors for label tracking based on the Media Type used. There is a reflective and transmissive sensor positioned slightly off centered in the media path. An optional adjustable black mark sensor is available. The sensor you will use requires configuration of the Tracking Mode (Mark/Web/Continuous) setting to function with the media you are using. A hole or black mark must pass over the media sensor's position to function correctly.

3. Calibrate the printer for the media.

The printer does not measure the label length unless the default Power Up or Head Close values are altered to either Length or Calibrate. There are two calibration methods to consider if the labels fail to calibrate properly.

- The 2 Flash sequence will find the label gap and measure the label.

- The 7 button flash will perform a deeper analysis of the gap or mark and will produce a media sensor profile.
