Cap absorbers, also known as purge unit pads, are small white cubes that play a crucial role in maintaining the proper operation and life of print heads. The main purpose of cap absorbers is to keep printheads in optimal condition by performing three main functions:

  1. Cleaning: When the printer is not in use or after a print job is completed, the cap absorbers act as a resting place for the print heads. They have a soft, absorbent surface that comes into contact with the print head nozzles, preventing them from drying out. In addition, cap absorbers are designed to hold a small amount of cleaning solution, which is used periodically to clean the print head nozzles. This cleaning process helps remove any dried-up ink or dirt that can build up on the nozzles and affect print quality.
  2. Humidification: the cap absorbers help maintain proper moisture levels around the print head nozzles. Proper humidity is critical to prevent the ink inside the nozzles from drying out, which can lead to clogging and poor print quality. By keeping the printheads moist when they are not actively printing, cap absorbers ensure they are ready for the next job.
  3. Sealing:during printing, the cap absorbers are raised and the print heads begin spraying ink onto the media. When the printing process stops, the cap absorbers are lowered again and seal the print heads to prevent their exposure to dust, air or other environmental factors that could cause clogging or drying out. In general, cap absorbers play a vital role in maintaining the health and performance of the print heads, ensuring consistent and high-quality prints over time. Regular maintenance and replacement of cap absorbers are essential to prevent potential problems and maximize the life of the printer’s printheads.

IMPORTANT! If you replace the print head, it is necessary to replace the cap absorbers as well. When replacing the print head, if you see goo on the old cap absorbers, call us (013 533 66 25). Probably then the cap absorbers needs to be replaced. Definitely do not print any further, as there is a chance that the printhead will fail again.
