  If the printer on your Tuttnauer Laboratory Equipment isn't printing, first make sure the paper is inserted correctly. If the issue persists, switch off the machine and switch it back on while pressing the feed button on the printer. If a test printout appears, the printer is likely okay, and there may be an electronics issue. Contact your dealer to solve the problem. If no test printout occurs, there is a problem with the printer. Contact your dealer to solve the problem.

  Thomas CoxAug 31, 2025
  The 'High Pres' message on your Tuttnauer Laboratory Equipment can be due to a few reasons. It could mean the air jet is clogged and needs cleaning. Another possibility is that the heating elements are staying on instead of cycling. A faulty or dirty temperature sensor (PT100) could also be the cause. For the latter two issues, it's best to call a technician.
