Troubleshooting issues with the Back of Truck System (BOTS/TruckSiS) label printer

If your label printer is printing one label, and then a blank second, you need to recalibrate it.

To calibrate the Zebra ZD420

• Make sure that the media and ribbon cartridge (if printing in thermal transfer mode) are properly loaded in the printer and that the top cover of the printer is closed.

• Press the POWER button to turn on the printer

• When the printer is ready (fixed Statoverde lamp), press and hold the PAUSE and CANCEL buttons for two (2) seconds, then release them. Refer to the following image:

 

 

• The printer should dispense 1 blank label. Run a test label to find out if this adjustment fixed your issue.

If this did not fix your issue, you may need to reset your label printer.

To perform a Reset Printer Factory Defaults procedure:

• Turn OFF the printer. 
• Press and hold PAUSE + FEED while turning ON the printer. 
• Hold PAUSE + FEED until the STATUS indicator ( ) is the only indicator lit. The printer configuration is reset to the factory default values. No labels print at the end of this action.

Another option to reset your label printer:

• Locate the reset access button (very small and thin, you may want to use a paper clip to access) Button is on the bottom of the printer, see image below.
• 
• Hold the reset button down for1-5 seconds- Printer performs a factory reset and will automatically
  print a configuration label (and network label if present)

Printer is Still NOT Printing 

Symptoms are 1 or more printers may not be printing. The built-in diagnostic on the BOTS will not print a test page for the dot-matrix or label printer.

• Be sure to load paper into the dot-matrix printer and attempt to print a test page.
• If neither printer will print a test page then most-likely the hub is disconnected or malfunctioning.
• Locate the hub underneath the BOTS just above the toolbox.
• Follow the 6inch round black cable from hub to extension cable. The hub might have become disconnected from the extension cable and just needs to be plugged back in. This may require taking the backplate off of the BOTS.

If the hub is connected then it may be malfunctioning. All devices may be unplugged and plugged back in to attempt to ‘reboot’ the hub. If the issue still persists then escalate to support.

 

If after following these steps the printer is not fully functional, please contact Smarter Sorting support.
