Abstract

PURPOSE:To prevent printing quality deterioration and printer failure both of which occur when a printer is started without a recovering unit being attached to a printer main body by generating a waste toner full charge detecting signal, and thereby stopping a printer. CONSTITUTION:When the waste toner recovering unit 11 is not mounted on the printer main body, a cam 12 rests by its own weight, a part B blocks a light emission opening 21, and a detecting part 13 generates the waste toner full charge detecting signal; thereby the printer does not start. Similarly, when the waste toner recovering unit 11 is filled with the waste toner almost completely, spherical rubber 14 swells up by the waste toner, the cam 12 abutting on the spherical rubber 14 turns, and consequently a part C blocks the light emission opening 21. As a result, the detecting part 13 generates the waste toner full charge detecting signal, and the printer stops. Thus, the printer does not operate when the waste toner recovering unit is not mounted on the printer main body.

Embodiments of the present invention will be described below based on the drawings. 1st
At step 121, the spherical rubber shell 14 is pressed onto the top surface of the waste toner collection unit 11. Then, the cam part 12 is pivoted to the detection part 13, and the detection part 13 is further fixed to the printer main body so that the cam part 12 comes into contact with the spherical rubber.

To explain this part in detail, as shown in FIG. 2, the detection section 13 fixed to the printer body has a cutout with a light emitting port 21 that sweeps light from a light emitting diode installed inside the detection section 13. When the light emitting diode is blocked by blocking the light emitting port 21, a waste toner full detection signal is generated and the printer is stopped. On the other hand, the cam part 12 pivotally attached to the detection part 13 can rotate around point A, and has a shape such that a part of the cam part 12 closes the light emitting port 12 depending on the angle of rotation.
