Issue | Possible Cause | Recommended Solution |
|---|---|---|
General print quality issues | The printer is set at the incorrect print speed. | For optimal print quality, set the print speed to the lowest possible setting for your application via control panel, the driver, or the software. You may want to perform the Feed Self Test to determine the optimal settings for your printer. See Print Speed for how to change the print speed. |
You are using an incorrect combination of labels and ribbon for your application. | Switch to a different type of media or ribbon to try to find a compatible combination.If necessary, consult your authorized Zebra reseller or distributor for information and advice. | |
The printer is set at an incorrect darkness level. | For optimal print quality, set the darkness to the lowest possible setting for your application. You may want to perform the Feed Self Test to determine the ideal darkness setting. See Print Darkness for how to change the darkness setting. | |
The printhead is dirty. | Clean the printhead and platen roller. See Clean the Printhead and Platen Roller. | |
Incorrect or uneven printhead pressure. | Set the printhead pressure to the minimum needed for good print quality. See Adjust the Printhead Pressure. | |
Loss of printing registration on labels. Excessive vertical drift in top-of-form registration. | The platen roller is dirty. | Clean the printhead and platen roller. See Clean the printhead and platen roller. |
Media guides are positioned improperly. | Ensure that the media guides are properly positioned. See Load the Media. | |
The media type is set incorrectly. | Set the printer for the correct media type (gap/notch, continuous, or mark). See Media Type. | |

Smudge marks on labels | The media or ribbon is not designed for high‑speed operation. | Replace supplies with those recommended for high-speed operation. |
Misregistration/skips labels | The printer is not calibrated. | Calibrate the printer. See Calibrating the Ribbon and Media Sensors. |
Improper label format. | Check your label format and correct it as necessary. | |
Misregistration and misprint of one to three labels | The platen roller is dirty. | Clean the printhead and platen roller. See Cleaning the Printhead and Platen Roller. |

The platen roller is dirty. | Clean the printhead and platen roller. See Cleaning the Printhead and Platen Roller. | |
Vertical image or label drift | The printer is using non‑continuous labels but is configured in continuous mode. | Set the printer for the correct media type (gap/notch, continuous, or mark—see Media Type) and calibrate the printer, if necessary (see Calibrating the Ribbon and Media Sensors). |
The media sensor is calibrated improperly. | Calibrate the printer. See Calibrating the Ribbon and Media Sensors. | |
The platen roller is dirty. | Clean the printhead and platen roller. See Cleaning the Printhead and Platen Roller. | |
Improper printhead pressure settings (toggles). | Adjust the printhead pressure to ensure proper functionality. See Adjusting the Printhead Pressure. | |
The media or ribbon is loaded incorrectly. | Ensure that the media and ribbon are loaded correctly. See Loading the Ribbon and Loading the Media. | |
Incompatible media. | You must use media that meets the printer specifications. Ensure that the interlabel gaps or notches are 2 to 4 mm and consistently placed (see Media Specifications). | |
The bar code printed on a label does not scan. | The bar code is not within specifications because the print is too light or too dark. | Perform the FEED Self Test. Adjust the darkness or print speed settings as necessary. |
There is not enough blank space around the bar code. | Leave at least 1/8 in. (3.2 mm) between the bar code and other printed areas on the label and between the bar code and the edge of the label. | |
Auto Calibrate failed. | The media or ribbon is loaded incorrectly. | Ensure that the media and ribbon are loaded correctly. See Loading the Ribbon and Loading the Media. |
