In a method for monitoring a pump arranged in a flow path to pump a fluid, the temperature of a fluid is regulated by a tempering element during the operation of the pump. The regulation of the temperature may include detecting at least one status point which is formed from an energy supplied to the tempering element and a temperature slope of the tempering element. The status point may be determined in a hazard range by checking whether the status point is located outside of a normal status range, which means that the lifespan of the pump is limited.

Method and system for monitoring a pump

An electrographic printer using a print web medium is provided with a web adjusting apparatus having a geared motor for adjusting the web position. A method and apparatus to compensate for backlash in the geared motor includes a sensor to detect an end position of rotation of the geared motor. A time being determined from a point of reversal of the geared motor to a decay in the sensor output indicating a gear backlash, and the time being added to the drive of the geared motor when reversing directions to adjust the web position.
