+ | [* black] Let's answer your last question about the printhead now: How does it print? |
---|---|
+ | [* black] The action starts in the second picture. |
+ | [* red] The ink inlet fills the chamber with ink (yellow). |
+ | [* yellow] The ink is prevented from exiting the nozzle by surface tension. |
+ | [* orange] (Third image) When the printer needs to print, electrical current is applied to the piezo element which expands, creates pressure, and forces a single drop of ink out of the nozzle. |
+ | [* black] The (microscopic) drop of ink falls on the paper. |
+ | [* orange] The contraction of the piezo element causes the remaining ink in the nozzle opening to be sucked back into the chamber. |
+ | [* black] Keep in mind that this printer has to control over 240 piezo elements which move over the paper many times in the time it takes to print a single page. |
