• Abnormal noise when head is moving
left and right
1-1
• Does the noise occur at the same time as the print head is printing?
The head of this ink jet printer uses piezo electric elements and it is the vibration of the piezo electric elements
that ejects the inks.
When a particularly large number of nozzles are ejecting at the same time and when the printing ratio is high,
the piezo vibration increases accordingly.
The vibration emits a noise like oscillation but this does not affect performance.
