Abstract: A drying assembly is disclosed. The drying assembly has at least 2 fan units where each fan unit has a fan. The fan speed of each fan is adjusted independently to control the air temperature from the fan. The airflow through all of the fans is maintained at a constant value.

Abstract: Examples are provided of controlling sheet media dryers. A controller operates a fan at plural duty cycles and correlates a resulting air pressure to each to define empirical data pairs. A parabolic curve fit to the empirical data is used to derive additional data pairs, and a lookup table is defined using the empirical and derived data pairs. The controller uses the lookup table to operate the fan during normal operations of a sheet media dryer.

Abstract: According to one example there is provide a printing system that comprises a carriage moveable bi-directionally across a platen. The system additionally comprises a substrate edge detector to detect the position of a lateral edge of a substrate when positioned on a platen, a parking zone in which a substrate edge holder may be parked, and a substrate edge holder pick-up system on the carriage to pick up a substrate edge holder parked in the parking zone and to position the substrate edge holder on a detected lateral edge of a substrate positioned on the platen.

Abstract: Controlling a temperature with a servomechanism. A temperature is monitored at the servomechanism for a period of time. A difference is determined between the temperature and a target temperature at the servomechanism. A target power gain is determined at the servomechanism to produce the target temperature such that the target power gain is determined based on a non-linear determination. A power gain is adjusted at the servomechanism to the target power gain based on a result of the determination such that the temperature is the target temperature.

Abstract: A method to determine an amount of remaining fluid in a replaceable fluid supply unit includes determining a first estimated fluid volume of a first replaceable fluid supply unit in communication with a fluid ejector unit, determining a first correction factor corresponding to the first replaceable fluid supply unit in communication with the fluid ejector unit including at least a first volume ratio parameter corresponding to a ratio of a first nominal fluid volume of the first replaceable fluid supply unit and the first estimated fluid volume, determining an amount of fluid consumed from a second replaceable fluid supply unit configured to replace the first replaceable fluid supply unit, and determining a remaining amount of fluid in the second replaceable fluid supply unit by subtracting the determined amount of fluid consumed from a second nominal fluid volume of the second replaceable fluid supply unit.
