IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18330038 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes an image forming apparatus that includes various components such as an image forming unit, rotary members, a web, feed roller, winding roller, contact member, detection unit, and control unit.

  • The apparatus has two power-ON states and a power-OFF state, and it is designed to detect the diameter difference of the web between these states.
  • If the diameter difference is equal to or greater than a predetermined value, the control unit prevents the image forming unit from creating a toner image.
  • However, if the diameter difference is smaller than the predetermined value, the control unit allows the image forming unit to create a toner image.

Potential applications of this technology:

  • This image forming apparatus can be used in various printing devices such as laser printers, photocopiers, and multifunction printers.
  • It can be implemented in both personal and commercial printing equipment.

Problems solved by this technology:

  • The apparatus prevents the formation of toner images when there is a significant diameter difference in the web, ensuring the quality and consistency of printed output.
  • This feature helps avoid potential issues such as misalignment, smudging, or poor image quality caused by variations in the web diameter.

Benefits of this technology:

  • By controlling the formation of toner images based on the diameter difference of the web, the apparatus ensures consistent and high-quality printing results.
  • It helps maintain the reliability and efficiency of the image forming process, reducing the need for reprints or manual adjustments.
  • The detection and control mechanism provided by this technology can contribute to cost savings by minimizing toner waste and improving overall productivity.


Original Abstract Submitted

An image forming apparatus includes an image forming unit, a first rotary member, a second rotary member, a web, a feed roller, a winding roller, a contact member, a detection unit, and a control unit. In a state where the apparatus is turned from a first power-ON state to a second power-ON state through a power-OFF state after the contact member reached a notch, if a difference between a diameter of a web at an end of the first power-ON state and the diameter of the web at a start of the second power-ON state is equal to or greater than a predetermined value, the control unit controls the image forming unit not to form a toner image. In the state after the contact member reached the notch, if the difference is smaller than the predetermined value, the control unit permits the image forming unit to form a toner image.
