11. The image forming apparatus according to claim 8, further comprising a sheet supply tray configured to receive a stack of recording sheets and disposed under the power supply unit as viewed in the axial direction.
12. The image forming apparatus according to claim 8, wherein when the detector detects the malfunction of the first fan, the controller stops heat generation of the fixing device.
13. An image forming apparatus configured to form an image on a recording sheet, comprising:
a main body;
a fixing unit including a heating element, the fixing unit configured to generate heat and fix a developer image transferred onto the recording sheet thereto;
a first fan disposed higher than the fixing unit as viewed in an axial direction of the heating element, the first fan configured to generate air in the main body around the fixing device;
a second fan disposed under the heating element as viewed in the axial direction and configured to generate air in the main body;
a controller configured to control operation of the first fan and the second fan; and
a detector configured to detect whether a malfunction of the second fan occurs,
wherein when the detector detects the malfunction of the second fan, the controller increases a voltage applied to the first fan as compared with the voltage applied before the malfunction was detected.

1-29. (canceled)
30. A medical fluid injector comprising:
a drive ram having a longitudinal axis;
a motor to move the drive ram along the longitudinal axis;
a syringe mount comprising first and second members that are pivotable toward and away from one another, the first member being pivotable about a first pivot axis, and the second member being pivotable about a second pivot axis different from the first pivot axis, wherein a line connecting the first and second pivot axes does not intersect the longitudinal axis of the drive ram, wherein the first and second members of the syringe mount, when in a first position, are engaged with a rearward end of a syringe to substantially immobilize the syringe relative to the motor, and wherein the first and second members of the syringe mount, when in a second position, are disengaged from the rearward end of the syringe so that the syringe may be removed from the syringe mount; and
a sensor for determining whether the first and second members of the syringe mount are in the first position or the second position.
31. The injector of claim 30, wherein each of the first and second members of the syringe mount comprises an arcuate surface.
32. The injector of claim 30, wherein each of the first and second members of the syringe mount is biased toward the longitudinal axis of the drive ram when the first and second members are in the first position.
33. The injector of claim 30, further comprising a housing that houses the motor and that allows the drive ram to extend out from the housing.
34. The injector of claim 30, further comprising a console in electronic communication with the sensor and adapted to generate at least one console control signal for the injector.
35. The injector of claim 34, wherein the at least one console control signal is interrupted when the sensor determines that the first and second members of the syringe mount are in the second position.
36. The injector of claim 34, wherein a first signal of the at least one console control signal signals the motor to move the drive ram along the longitudinal axis in a first direction, and wherein the first signal is prevented from being delivered to the motor when the sensor determines that the first and second members of the syringe mount are in the second position.
37. The injector of claim 34, wherein the sensor is adapted to deliver a signal comprising positional information for the first and second members to the console.
38. The injector of claim 30, further comprising software that is adapted to allow manual control of the injector when the sensor determines that the first and second members are in the first position.
39. The injector of claim 30, wherein the syringe has contrast media disposed therein.
