A method for the deinking of wastepaper which comprises converting the wastepaper to a pulp, contacting the pulp with an aqueous medium of alkaline pH containing between about 0.2 and 2 percent by weight, calculated on dry weight of the pulp, of a deinking agent which is one or a mixture of certain thiol ethoxylate compounds, and treating the resulting pulp-containing medium to remove suspended or dispersed ink. The use of a thiol ethoxylate deinking agent offers a high level of performance in such a deinking process, both from the standpoint of the overall brightness and dirt count of paper prepared from the deinked pulp. In certain specific embodiments, the invention further comprises a step for treating thiol ethoxylate containing process streams and effluents to convert the surface active deinking agent to low-foaming sulfonyl derivatives, or to degrade the deinking agent to non-surface-active matter.
It has now been found that certain thiol ethoxylate compounds are very usefully applied as deinking agents in processes for the deinking of printed wastepaper. Processes applying the thiol ethoxylate deinking agents are found to offer a high level of performance, both from the standpoint of the overall brightness and dirt (ink particle) count of papers prepared from the deinked pulp.
Accordingly, in broad terms the present invention is briefly described as a process for the deinking of wastepaper stocks, which comprises steps for
a. converting the wastepaper to a pulp,
b. contacting the pulp with an aqueous medium of alkaline pH containing between about 0.2
and 2 percent by weight, calculated on dry weight of the pulp, of a deinking agent which is
one or a mixture of thiol ethoxylate compounds of the formula
RS--CH.sub.2 CH.sub.2 0).sub.n H
wherein R represents a C9 to C18 alkyl group and n has an average value between about 3 and
20, and
c. treating the resulting pulp-containing medium to remove suspended or dispersed ink there
from.
In certain preferred embodiments, the invention additionally comprises process steps for treatment of deinked pulp and/or aqueous process streams which contain the deinking agent. In one respect, these preferred embodiments are directed to implementing observations that process streams containing deinking agent can be treated to convert all or part of the thiol ethoxylates to corresponding sulfonyl compounds. In particularly preferred embodiments, the invention comprises a step which accomplishes both a bleaching of the pulp and a conversion to sulfonyl derivatives. It is found that at least a portion of the deinking agent is converted to these derivatives in the presence of oxidizing agents and under conditions typical of bleaching steps conventionally applied in wastepaper deinking processes. Conversion to the sulfonyl derivatives is beneficial, for instance, in order to eliminate problems associated with foaming produced by carryover of surfactant into downstream processing steps or into effluent wastewater streams/Relative to the thiol ethoxylates, the sulfonyl derivatives have a greatly reduced tendency to promote foaming in aqueous solution. In another respect, certain

preferred embodiments of the invention are directed to treatment of deinked pulp and/or other process streams to accomplish a degradation of the thiol ethoxylate deinking agent and/or its sulfonyl derivatives into non-surface-active matter. Such embodiments provide for. one or more steps in which the surfactant-containing process stream is contacted with an oxidizing agent under specified conditions of pH and temperature. Conversion of deinking agent to non-surface-active matter may be applied, for instance, to facilitate its removal from pulp fibers or to improve the quality of process effluent wastewater streams.
Background of the Invention
An information technology environment uses computers, software, and networks to share information from one place to another with rapid processing. Nowadays digitization of information is excellent from the view point of storage, accumulation, search, and the like of the information. But in this digital world paper has its own important to deliver message or news or information from one place to another. Most business people look at printers as a necessity. Electronic files can be sent instantly around the world and offer a convenience for travellers. Still, holding a piece of paper with your data has its advantages. Because of which, the amount of paper used is increasing in this digital information world. On the other hand printers kill trees. On average, a smaller office with 10 to 15 employees will consume enough paper to necessitate cutting down 18 trees a year. 64-Bit toner and ink are made with chemicals that can cause environmental damage. The paper and 64-Bit toner or ink get delivered to your office generates carbon, and the garbage gets hauled away, which generates more material in landfills and more carbon for the delivery process. Printers also consume a great deal of power, with the fusers in laser printers consuming hundreds of watts when they run. If the paper medium and paper media recycled then to deal with above problems can be possible.
If text or data written on the paper medium is erased, then recycling of the waste paper medium is possible. Also recycling of ink also possible using absorption method various procedures applied on this waste paper medium to reuse it again for another purpose. By applying all erasing procedures, images or text are invisible to human eye so can be reused for other purpose. Present invention states the reuse of waste paper and printed text ink.
Objective of the Invention
• The objective of the invention is to develop 'Intelligent Printing Mechanism' which recycles not only printing medium but also printed text ink. The objective of the invention is to reutilize waste paper and printed text ink to avoid wastage of new paper and ink which helps to follow "Go Green India" slogan.
• Another objective is to provide a mechanism which is used in normal printer which can do printing and erasing both applications without interference of one another.
• One more objective is apply the necessary erasing procedure as per direction of sensor and scanner to maintain paper quality and avoidance of unnecessary erasable procedures on the paper/waste paper.
Summary of the Invention
The invention allows reusing of waste paper sheet and printed text ink to minimize the cost of new paper and printer ink used in the printer. This can be achieved by recycling the waste paper and printer ink with the help of present invention.
The invention uses three different techniques which remove the text of any type like pencil text or pen text or printer text from the waste paper to reuse the same paper for next printing purpose. These techniques do not interfere in one another or normal printing procedure. These techniques include 'Erasable mechanism', 'Heating Mechanism' and 'White ink

spreading mechanism'. These procedures are applied on the waste paper based on the different conditions like whether paper is full of pencil text or printer text or pen text or all three types of texts or patterns. These conditions are checked by scanner and sensor used in the system and according to the direction of scanner and sensor these procedures are applied on it.
According to the invention 'Erasable technique' erases pencil text using erasable chip in head l..In 'Heating technique' hot air is blown through head 2 over character (pixels of character) or pattern up to melting point of printed text ink on the paper with the help of temperature sensor and that melted plastic ink (text ink) is fused and absorbed in head 2.This melted plastic ink collected in the container and used in ink 64-Bit toner. Even if waste paper sheet not cleaned by above two techniques is cleaned using white ink spreading technique. During which white ink is spreader over the pixels of pattern or pixels of character on the waste page through head 3 to minimize or diminish the effect of texts or patterns on the page which should be invisible to human eye.

Description of the invention
The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art, techniques and approaches are overcome by the present invention as described below in the preferred embodiments.
FIG. 1 shows overall flow of the Intelligent Printer system. The Intelligent Printer machine comprises of input tray 110, normal printing mechanism 120, output tray 130 and reverse printing mechanism 140.
In current context of the invention, The Intelligent printing mechanism 140 states how actual working of the erasing procedure takes place inside the printer without affecting normal printing mechanism. It consists of different procedures, sensors and scanners. The printer machine accepts the input sheet/waste paper sheet from the user via input tray 110 inside the printer. For the purpose of erasing texts, images and scratches over the page/waste page when information gets fetched the machine checks pencil, pen and printer text or images via sensor and scanner. If pencil text detected via Graphite PZR sensor 150 then erasable 64-Bit tonerl60 activated if not then working moves to Optical character recognition scanner 170 if it identifies printer text then heating procedure 180 applied with the help of temperature sensor 190. Then flow moves to detect pen writing text which is sensed by Optical sensor or handwriting recognition 200andas per result of it white ink spreading 210 takes place. This whole procedure is done in the Erasing printing box 140. Output of this box that is blank paper sheet is directed towards output tray 130.Normal printing 120 takes place as per the normal way.
The Intelligent Printing System 100 has a reverse printing module consist of hardware and software mechanism. The Intelligent Printing System recycles the waste printing page and text ink used over the page/waste page and thus saves all the cost at paper and ink manufacture material. The hardware part consists of sensors and scanners used in the printer and software part runs this hardware through software mechanism. The hardware is designed

to eliminate unnecessary procedures over the printing page to maintain the paper quality.
Software mechanism directs the machine, at what condition which sensor and scanner will work. The Intelligent Printing System 100 automatically integrates hardware and software part to reuse the paper and ink.
The whole system reuses paper as well as printer ink and helps to save trees and earth. This system saves the cost of paper and ink manufactures by reusing the page and printer ink. This whole system is user friendly too because all this procedures done in normal printer without any overhead.
FIG 2 shows flow diagram of erasing mechanism 200 used in the Intelligent printing system. Initially user inserts paper sheet/waste paper sheet in the input tray 210. Paper/waste paper should be checked for 220 different patterns or text. Graphite PZR sensor 230 senses pencil written pattern on the page, if pencil text present on the paper 240 sensor gives signal to enable 'Erasing procedure' 260 if not then flow moves to next procedure that is heating procedure 250. As per signal activation of sensor, head 1 erases pencil pattern pixel by pixel 270. Head 1 contains erasing material chip present on the head 1 with high melting point. This erasing material chip can be replaced as per use. Dust formed after erasing text collected in the empty box of the printer 280. As head 1 move over pixel by pixel it erases that character and at that time only dust particles are captured in the headl which is collected in the empty box of the printer. Then flow moves to check whether paper completely cleaned or not 290, if paper completely cleaned then paper moved to the heating procedure 300. If not then run the erasing procedures 260 on the whole page pixel by pixel. FIG 3 shows flow diagram of 'Heating Mechanism' 300 used in the Intelligent Printing System. Paper/Waste paper inserted in the printing system only once in same place and these procedures (200,300,400 and 500) are applied on the page at that place only. By successful cleaning page left to the output tray for reuse. In heating procedure 300, initially printer text on the paper has been checked 320 whether it is present or not. This has been checked by 'Optical Character Recognition' scanner 330, which identifies printer text pattern 340 and directs the flow towards heating mechanism 360 if not then flow moves towards next mechanism 350 that is white ink spreading mechanism. As per direction of Optical Character Recognition scanner heating mechanism should be activated 360. In heating mechanism heated air blown through head 2 over a pixel by pixel, which melts the printer text ink made up of plastic printer ink 370. Here Temperature sensor 380 is introduced to maintain the temperature of hot air. This heated air applied to the page through head 2 up to a character printed on the paper melts 370 and vanishes its effect of the printed text to clean the paper. Melted plastic ink is collected in the container 400 of the printer to reuse the printer ink. This whole process must be going on up to end of page or up to whole printer text erased 410. If paper is completely erased during heating mechanism then flow moves to next mechanism 420.
FIG 4 shows block diagram of the 'Ink Recycle Mechanism' 400. Printer ink is made up of combination of chemicals including polymer, carbon. This means that printer ink is quite plastic type of ink which is melted by applying heat. This printer ink contains harmful chemicals which affects an environment. So by reusing this printer ink one can help an environment from side effects of this printer ink and carbon emission. FIG 4 shows block diagram of the 'Ink Recycle Mechanism' 400 to reuse the printer ink. During this procedure paper from input tray 410 is heated by hot air. This mechanism is part of 'Heating Mechanism' 300. Here hot air applied to the page through head 2 420 by using temperature sensor 430. Hot air applied by pressure to pixel by pixel over the whole page, during which printer ink has been melted. This melted ink is fused and captured through head2 440by applying cold air 450 on the melted air to form dust particles of the melted ink. This mechanism is done using head2 over pixel by pixel (character/pattern pixels). This dust formed ink is collected in the container 460 and used in the ink 64-Bit toner of the printer 470.

FIG 5 shows block diagram of the 'White Ink Spreading Mechanism' 500. Before applying White Ink Spreading Mechanism on the paper sheet/waste paper sheet, it is processed through erasing mechanism 200 and heating mechanism 300 in the input tray 510. Initially handwritten pattern is checked before applying White Ink Spreading Mechanism. Handwritten pattern is checked by using optical sensor 520 or handwriting recognition 530. If this sensor identifies handwritten pattern then White Ink Spreading Mechanism is applied on the page. In which white ink 64-Bit toner must be there in the printer. Once sensor senses any writing by pen, pencil or printer text, white ink spreading takes place over the character through head 3 540. This mechanism not only eliminates handwritten text but also eliminates scratches or any instance of pen, pencil or printer texts and characters. This white ink spreading takes place over a pixel by pixel or the instance of scratches done by pen. This mechanism eliminates the text which is not erased by erasable 64-Bit toner and heating mechanism, by end of this process paper sheet forwarded towards output tray 550 for next reuse of the paper.
All these three techniques (Erasable mechanism, Heating mechanism and White ink spreading mechanism) are applied one after another as per direction of scanner and sensor. If sensor not identifies pencil text then erasing mechanism is avoided and workflow moves towards next scanner. If scanner identify printer text then only heating mechanism applied over the page, if not then workflow moves towards next procedure that is white ink spreading mechanism. Again if necessary then only this technique applied on the page otherwise paper sheet forwarded towards output tray. This is the whole procedure of ' Intelligent Printing Mechanism'.
