Printer is a kind of equipment that is very commonly used in the office, because many manufacturers of office equipment will develop and innovate for printers, and strive to make printers more intelligent, so as to provide office work efficiency. In the working process of the printer, Everlight's photoelectric switch plays an indispensable role, so what role does Everlight's photoelectric switch play on the printer?

The application model and principle of Everlight photoelectric switch on the printer

Front cover back cover induction

There is usually a small protrusion on the front cover or the back cover corresponding to the front and rear cover sensor switch (usually a micro switch), and Everlight’s through-beam slot-type photoelectric switch ITR20403 is installed here. Of course this will be based on the slot distance To decide the model. But it mainly works. If the front cover and back cover are not closed tightly, it will stop the printer. Because if the front and rear covers are not closed tightly, light leakage will occur during printing or copying, which will affect the print and copy results.

Paper feed sensor

The paper feed sensor will use Everlight's reflective photoelectric switch ITR8307-TR8. His main function is to detect paper size and ink usage.

Light guide strip is classified as inspection

This is also applied to Everlight’s reflective photoelectric switch ITR8307-TR8. If the light guide bar is not returned to its position after printing, it will transmit a signal to return the light guide bar to its position.

Slot-type photoelectric switch ITR20403, ITR9606-F, reflective photoelectric switch ITR8307-TR8, these models are suitable for printers. For the printer indicator model, Everlight recommends the use of 204-10 in-line LED lights.
