Abstract
An ink printing device has a dryer chamber that is connected via two openings with the internal space of the printer. To detect whether operational exhaust air flows, as leakage air, from the drying chamber into the internal space, the temperature in the opening region may be measured and compared with a reference value. Given a temperature difference above a threshold value, an error signal is generated and/or corresponding countermeasures are taken in order to reduce the leakage.
