The first thing you should do when your label printer is acting up: check all the hardware.

• Open the printer. Make sure there is paper, with the label side facing up. Reset the paper, close the printer and hit the feed button, just to double-check.
  
• Check the power cord. Is it correctly plugged into both the printer and the power source?
• If it's connected via an Ethernet cord, check if it's correctly plugged into the printer and the router or switch? Try plugging it into a different port on the router or switch.
• If it's a USB cord, is it correctly plugged into the printer and the back of your computer? Try plugging the USB into a different port on your computer.

Sometimes, the stickiness from the labels can get on the roller or other parts of the printer. Make sure your device is clean by using an alcohol wipe (or something similar) to help remove any buildup.

If this is the first time the label printer is being hooked up - in general, or on this computer - you will need to go through the installation process for the printer. Article: Hardware - Install the Zebra Label Printer 

Ethernet connection issues

Check if the connection light on your ZD410 is green. If it's red (or off) the printer is not correctly connected to your network.

You can also print a network configuration page by holding the Feed and Cancel buttons at the same time (for about three seconds).

If the IP address on the second label is all zeros (000.000.000.000), the printer is not correctly connected to your network.

Start by checking the cord connecting your printer to the router. Is it correctly attached to both the computer and router? Is it torn or fraying?

Try connecting to another port on your router. Or, if the cord is torn or fraying, you might want to replace it.

In an emergency, you can quickly connect your ethernet-capable ZD410 to the computer with a USB cord instead of an Ethernet cable.

USB connection issues

If your label printer is not working on the computer it's physically connected to, try plugging it into a different USB outlet on the computer.

Ethernet connection issues

The networked label printer isn't printing

1. If you're having issues printing from a networked computer, first make sure the label printer is powered on and connected to your network router or switch with an ethernet cable.
   1. Check that the ethernet cable is firmly plugged into the back of the printer and into an open port on your router or network switch.
   2. Look for a solid or blinking link light on the printer where the cable plugs in — this confirms the printer has a network connection.
   3. If there's no link light, try a different ethernet cable or a different port on your router.
2. Next, confirm the printer has a valid IP address.
   1. On the printer itself, print a configuration page (this is usually done by holding the Feed button while powering the printer on — refer to your printer's manual if needed).
   2. Look for the IP Address on the printed page. It should show something like 192.168.1.X. If it shows 0.0.0.0, the printer hasn't connected to the network yet — check your cable and router connection and try again.
3. Make sure the printer is added correctly on the computer you're trying to print from.
   1. Go to Printers & Scanners (within Bluetooth & devices).
   2. Check if the label printer is listed. If it's not, you'll need to add it.
   3. Click Add a printer or scanner and wait for the printer to appear. Select it and follow the prompts.
   4. If it doesn't appear automatically, click The printer that I want isn't listed, then choose Add a printer using an IP address or hostname and enter the IP address from the configuration page you printed in step 2.
4. If the printer is listed but still not printing, try removing it and adding it again using the steps above.
5. If you're still having trouble, check the Network and Sharing settings on the computer. See the File and Printer Sharing section of our article, Configuration - Windows® Settings for Ascend.

Ascend freezes (when you try to print labels)

1. Print a test page on the computer.
   1. Navigate to Printers & Scanners.
   2. Select the label printer.
   3. Select Printer Properties.
   4. Click Print test page.

If it printed, go to Ascend and check Options > Label to see if the correct printer is selected in the drop-down menu.

If it does not print a test page, see if there is a back-up of documents waiting to print. 

1. Navigate to Printers & Scanners.
2. Select the label printer.
3. Select See what's printing.
4. Delete all items from the list. 

Troubleshooting Windows computers

If your computers have Windows and your printer is not working, check these items:

1. Navigate to Printers & Scanners
2. See if you have a default printer set:
   1. The default printer has a green checkmark by it.
3. If there is not a green checkmark by any printers, set one:
   1. Right-click a printer (ideally the report printer).
   2. Select set as default printer
   3. A Windows message displays letting you know Windows is not managing your default printer.
   4. Click OK.

Labels that are askew

If your labels are askew or you're getting some blank labels mixed in with your labels, you should check your label sizes in Devices and Printers.

1. Navigate to Printers & Scanners
2. Select your label printer.
3. Select Printing Preferences.
4. Go to Options.
5. Update the Size to:
   1. Wdith of 2.3
   2. Height of 1
6. Click Apply.
7. Go to Ascend.
8. Open Options > Label.
9. Select the Refresh printers icon.
10. Click Apply. 
11. Select Print Sample Barcode.

If your labels are still not right, you can adjust the margins in Ascend > Options > Labels.

If your settings are correct, but your labels still aren't printing correctly, you may need to calibrate it to set it back to its factory default settings.
