      Beverly HenrySep 23, 2025
      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.

    Why does Tuttnauer 3870E exhaust stage take so long?
    • C
      Courtney OsborneSep 23, 2025
      If the exhaust stage of your Tuttnauer Laboratory Equipment cycle is taking a very long time, it's normal if you are running a ‘liquids’ program. The slow exhaust can take between 15 and 20 minutes.

    What causes 'High Pres' to be displayed on Tuttnauer 3870E?

      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.
