Whenever your imprint quality is not satisfactory anymore, it is recommended to clean your print head. This can be done with a damp lint-free piece of cloth. The plastic parts of the e-mark (the docking station, bottom side of the e-mark or the cover) can be easily cleaned with a moistened cloth (pure water without cleaning agent!). If you are using the app, there is a button for manual cleaning of the nozzles if needed.

In order to ensure a steady imprint quality, we recommend that the e-mark be used regularly. If you have not used your e-mark for a while, make sure you clean the print head and recharge the battery. Please note that the e-mark print head cleans itself automatically every time it is taken out from the docking station. Please follow the instruction in the user manual or watch the video demonstration.

The quality of the imprint depends on several different aspects. Most of the problems can be put down to the cartridge. Either the print head is (slightly) dried out, the cartridge is (almost) empty or not inserted rightly. If imprint quality is decreasing, please consider the following points:

• Always put the e-mark in the docking station immediately after usage to avoid drying out of print head
• Cleaning the print head by wiping over it with a damp cloth
• Cleaning the plastic parts on the bottom of the e-mark (around the print head)
• Pull out cartridge and re-insert it
• Ensure a proper surface to print on (e.g. sheet of paper on hard underground, no rippled surfaces)
• Try to move as straight as possible over the surface
