The USB Host Port Is Not Acknowledging a USB Device
The printer is not acknowledging a USB device or is not reading the files on a USB device that is plugged into the USB host port.
The printer currently supports USB drives only up to 1 TB in size.
Use a USB drive that is 1 TB or smaller.
The USB device may require its own external power.
If your USB device requires external power, make sure that it is plugged into a working power supply.
Printer Parameters Are Not Set As Expected
Changes in parameter settings did not take effect.
OR
Some parameters changed unexpectedly.
A firmware setting or command prevented the ability to change the parameter.
Check your label formats or the settings of the software that you use to send formats to the printer.
If necessary, refer to the Zebra Programming Guide or call a service technician. A copy of this guide is available from zebra.com/manuals.
A command in a label format changed the parameter back to the previous setting.
IP Address Changing
My printer reassigns a new IP address to the print server after the printer has been off for a while.
The settings for your network are causing the network to reassign a new IP address.
If the printer changing IP addresses causes issues for you, follow these steps to assign it a static IP address:
  1. Find out what values need to be assigned to the IP address, subnet mask, and gateway for your print server (wired, wireless, or both).
  2. Change the appropriate IP protocol value to PERMANENT.
  3. Change the values for the IP address, subnet mask, and gateway for the appropriate print server to what you want them to remain.
  4. Reset the network by touching
    Menu
    Connections
    Networks
    Reset Network
     and then touching the check mark to save the changes.
Cannot Connect through Wired or Wireless Connections
I manually entered a wireless IP address, subnet, and gateway on my printer, but it won’t connect to my wired or wireless network.
The printer’s network must be reset after values are changed.
Reset the network by touching
Menu
Connections
Networks
Reset Network
 and then touching the checkmark to save the changes.
An ESSID value has not been specified.
  1. For a wireless connection, specify the ESSID value that matches the value used by your wireless router using the following Set/Get/Do command:
    ! U1 setvar "wlan.essid" "value"
    where "value" is the ESSID (sometimes called a network SSID) for your router. You can look on the back of your router for a sticker with the router’s default information.
    If the information has been changed from the default, check with your network administrator for the ESSID value to use.
  2. If the printer still does not connect, reset the network by touching
    Menu
    Connections
    Networks
    Reset Network
     and then touching the checkmark to save the changes, and then power-cycle the printer.
The ESSID or other value was not specified correctly.
  1. Print a network configuration label and verify that your values are correct.
  2. Make corrections as necessary.
  3. Reset the network by touching
    Menu
    Connections
    Networks
    Reset Network
     and then touching the check mark to save the changes.
