The injection device (2) also comprises a processor to control the drive mechanism (42), a dispense button (18) to generate a signal to the processor to cause the medicament to be expelled and a priming detector to detect a predetermined orientation of the injection device. When the predetermined orientation is detected the processor will only actuate the drive mechanism (42) to expel a small amount of medicament.
