A method of detecting a level of printable fluid in a container includes, with at least one sensing location on a die in thermal contact with the printable fluid in the container, sensing a voltage of a capacitor over time as current from the capacitor leaks through a field effect transistor (FET). The FET and capacitor are associated with the sensing location. The method may further include, based on the voltage of the capacitor over time and a threshold voltage, determining whether the printable fluid is present at the at least one sensing location.

Devices and methods for identifying categories or types of print media in image forming apparatuses are disclosed. In an example method print media are advanced in a feeding direction to reach a cutting position, a cutter is advanced in a cutting direction, perpendicular to the feeding direction to cut the print media, friction between the cutter and the print medium is measured, and the print media are identified based on the measured friction.

According to an example, an apparatus may include an automatic document feeder, printing components, an externally accessible embedded finishing mechanism, an illumination source to direct attention to the embedded finishing mechanism, and a controller. The controller may determine whether a certain condition has been met pertaining to media sheets fed into the automatic document feeder or printed by the printing components, and in response to a determination that the certain condition has been met, may activate the illumination source.
