MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611008832 A) filed by Swami Vivekananda Subharti University, Meerut, Uttar Pradesh, on Jan. 29, for 'a method and a system for adaptive, feedback-controlled laser de-printing for selective toner removal and paper reuse.'
Inventor(s) include Er. Amit Kumar; Er. Subham Tyagi; Er. Sandeep Kumar; and Er. Reshu Kumar.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an adaptive, feedback-controlled laser de-printing system and method for selective removal of toner or ink from printed paper to enable safe and repeated paper reuse. The system employs a laser source configured to irradiate printed regions of a paper substrate, one or more surface-response sensors for real-time monitoring of paper conditions, and a controller configured to dynamically regulate laser parameters based on sensed feedback. Laser power, pulse duration, duty cycle, and scan speed are adaptively adjusted to detach toner or ink while preserving paper fiber integrity. A synchronized particulate removal unit extracts detached toner particles to prevent redeposition. The system further stores operational data to optimize subsequent de-printing cycles and support multiple reuse operations."
