I assume you mean the frequency at which the head moves back and forth. If this happens only at a certain frequency, then it sounds as if that is caused by resonance - which happens when the excitation (in this case, the head moving back and forth) has a similar frequency to the object's (the printer's) natural frequency.
A: Any amplifier will reach a frequency cut off point because of hindered circuit capability however the roll of bust be controlled especially when reaching oDB point must be at a -3 db roll off to prevent hi frequency oscillation
Beats are caused by the interaction of two waves with different periods. The Waves crests do not line up every oscillation, but when they do, they have a much larger than normal crest, which results in an observable beat.
When the ring is plucked, the force of gravity acting on the added load causes the ring to be displaced from its equilibrium position. This displacement results in a restoring force that causes the ring to oscillate. The increased load adds to the inertia of the system, causing the frequency of the oscillation to increase.
Thermal inkjet printer causes ink on print head to boil.
High frequency hearing loss can be caused by exposure to loud noises, aging, genetic factors, certain medications, and diseases like Meniere's disease or otosclerosis.
Drum percussion is so loud because of the oscillations of the drum surface. The oscillation of drum surface causes oscillation of air molecules and loud noise.
Gene mutation causes the phenotype frequency in a population to change after each generation.
Oscillations (vibrations) are damped when they are changed by some action. For example, touching an oscillating (vibrating) tuning fork with your finger is said to be damping it. The oscillation (number of Hertz) of an electrical oscillator, such as a TV tuner, is changed by varying the settings of the tuner.
If you subtract from the carrier frequency the frequency of the tone that modulates it, then filter out the carrier frequency, then you have a lower sideband frequency. If you add to the carrier frequency, filter out the carrier, then you have an upper sideband frequency.

If you have strong urine, there could be several causes, ie: Dehydration, medications, or certain foods such as asparagus which causes a metallic smell. The bladder is actually quite small and certain medical conditions can increase frequency of urination and or strong odor or color.
A vertical mass spring system consists of a mass attached to a spring that is suspended vertically. When the mass is displaced from its equilibrium position, the spring exerts a restoring force that causes the mass to oscillate up and down. The key characteristics of a vertical mass spring system include its natural frequency of oscillation, amplitude of oscillation, and damping factor that determines how quickly the oscillations decay over time.
