1. Recommended cleaning plan
Depending on the application and the media, cleaning may be performed more frequently.

  • Clean the print head. Method: 95% alcohol solvent, time interval: After using one media roll in thermal mode, or after running out of ribbon or every three rolls of media in thermal transfer mode.
  • Clean the ZM400 platten roller. Method: 95% alcohol solvent, time interval: After using one media roll in thermal mode, or after running out of ribbon or every three rolls of media in thermal transfer mode.
  • Clean the media sensor. Method: Air rush, time interval: After using one media roll in thermal mode, or after running out of ribbon or every three rolls of media in thermal transfer mode.
  • Clean the ribbon sensor. Method: Air rush, time interval: After using one media roll in thermal mode, or after running out of ribbon or every three rolls of media in thermal transfer mode.
  • Clean the media path. Method: 95% alcohol solvent, time interval: After using one media roll in thermal mode, or after running out of ribbon or every three rolls of media in thermal transfer mode.
  • Clean the ribbon path. Method: 95% alcohol solvent, time interval: After using one media roll in thermal mode, or after running out of ribbon or every three rolls of media in thermal transfer mode.


2. Cleaning steps
a. Clean the printer case
Use a lint-free cloth and a small amount of neutral detergent to clean the exterior of the printer, not to use harsh abrasive cleaners or solvents.

b. Clean the ZM400 printhead and Zebra ZM400 platten roller
Through routine maintenance, printhead wear can be minimized and print quality maintained. As the print progresses, the media or ribbon passing through the printhead will continue to wear the ceramic protective layer, exposing and eventually damaging the print component points, avoiding corrosion;

  • Frequently clean the printhead and use a backing and fully lubricated thermal transfer ribbon to reduce friction.
  • By optimizing the balance between the two, use the minimum printhead pressure and firing temperature settings.
  • Ensure that the thermal transfer ribbon width is greater than or equal to the width of the label media to protect the print elements from exposure to more corrosive label materials.

For best results, the printhead should be cleaned after each ribbon roll change. Unstable print quality, such as printed barcodes or blanks in the graphics, may indicate that the printhead is dirty.

CAUTION: When performing tasks with a heat source close to the bare printhead, remove all rings, watches, long necklaces, identification cards, and other metal objects that may come into contact with the printhead.
CAUTION: The print head is hot and may cause severe burns. The print head should be sufficiently cooled.
CAUTION: Before touching the printhead assembly, touch the printer metal bracket or use an antistatic wrist strap or pad to discharge accumulated static electricity.

To clean the ZM400 printhead and platten roller, complete the following steps:

  1. Open the printhead assembly
  2. Remove media and ribbon
  3. Wipe the end of the brown strip of the printhead assembly to the other end using a clean cotton swab
  4. When manually rotating the pressure roller, use a cotton swab to thoroughly clean and let the solution evaporate.
  5. Reload the media and ribbon and close the printhead assembly.

Note: If the print quality does not improve after performing the above steps, try using the Save-a-Printhead cleaning film to clean the printhead, a specially coated material that can remove accumulated dirt without damaging the printhead.

c. Clean the media compartment and sensor
To clean the media compartment and sensor, complete the following steps:
Use a brush or vacuum cleaner to remove confetti and dust from the media and ribbon paths.
Use a brush or vacuum cleaner to remove confetti and dust from the sensor.
