A4 Copy Paper Hs Code

[Jule Watkinson]

Inthe mid-1980s Xerox pioneered an encoding mechanism for a unique number represented by tiny dots spread over the entire print area, and first deployed this scheme in its DocuColor line of printers. Xerox developed this surreptitious tracking code "to assuage fears that their color copiers could be used to counterfeit bills"[1] and received U.S. Patent No 5515451 describing the use of the yellow dots to identify the source of a copied or printed document.[2][3] The scheme was then widely deployed in other printers, including those made by other manufacturers.

The public first became aware of the tracking scheme in October 2004, when it was used by Dutch authorities to track counterfeiters who had used a Canon color laser printer.[4] In November 2004, PC World reported the machine identification code had been used for decades in some printers, allowing law enforcement to identify and track counterfeiters.[1] The Central Bank Counterfeit Deterrence Group (CBCDG) has denied that it developed the feature.[2]

In 2005, the civil liberties activist group Electronic Frontier Foundation (EFF) encouraged the public to send in sample printouts and subsequently decoded the pattern.[5] The pattern has been demonstrated on a wide range of printers from different manufacturers and models.[6] The EFF stated in 2015 that the documents that they previously received through a Freedom of Information Act request[7] suggested that all major manufacturers of color laser printers entered a secret agreement with governments to ensure that the output of those printers is forensically traceable.[6]

Although we still don't know if this is correct, or how subsequent generations of forensic tracking technologies might work, it is probably safest to assume that all modern color laser printers do include some form of tracking information that associates documents with the printer's serial number. (If any manufacturer wishes to go on record with a statement to the contrary, we'll be happy to publish that here.)

As of 2011[update], Xerox was one of the few manufacturers to draw attention to the marked pages, stating in a product description, "The digital color printing system is equipped with an anti-counterfeit identification and banknote recognition system according to the requirements of numerous governments. Each copy shall be marked with a label which, if necessary, allows identification of the printing system with which it was created. This code is not visible under normal conditions."[10]

The dots can be made visible by printing or copying a page and subsequently scanning a small section with a high-resolution scanner. The yellow color channel can then be enhanced with an image processing program to make the dots of the identification code clearly visible. Under good lighting conditions, a magnifying glass may be enough to see the pattern. Under UV-light the yellow dots are clearly recognizable.[12]

Using this steganographic process, high-quality copies of an original (e.g. a bank note) under blue light can be made identifiable. Using this process, even shredded prints can be identified: the 2011 "Shredder Challenge" initiated by the DARPA was solved by a team called "All Your Shreds Are Belong To U.S." consisting of Otavio Good and two colleagues.[13][14]

Both journalists and security experts have suggested that The Intercept's handling of the leaks by whistleblower Reality Winner, which included publishing secret NSA documents unredacted and including the printer tracking dots, was used to identify Winner as the leaker, leading to her arrest in 2017 and conviction.[15][16]

Copies or printouts of documents with confidential personal information, for example health care information, account statements, tax declaration or balance sheets, can be traced to the owner of the printer and the inception date of the documents can be revealed. This traceability is unknown to many users and inaccessible, as manufacturers do not publicize the code that produces these patterns. It is unclear which data may be unintentionally passed on with a copy or printout. In particular, there are no mentions of the technique in the support materials of most affected printers. In 2005 the Electronic Frontier Foundation (EFF) sought a decoding method and made available a Python script for analysis.[17]

In 2018, scientists from TU Dresden developed and published a tool to extract and analyze the steganographic codes of a given color printer and subsequently to anonymize prints from that printer. The anonymization works by printing additional yellow dots on top of the printer's tracking dots.[18][11][19] The scientists made the software available to support whistleblowers in their efforts to publicize grievances.[20]

Other methods of identification are not as easily recognizable as yellow dots. For example, a modulation of laser intensity and a variation of shades of grey in texts are feasible. As of 2006[update], it was unknown whether manufacturers were also using these techniques.[21]

I recently purchased the PIXMA 922 and have been having issues printing. I have put standard Staples copy paper in the lower tray. When I go to print it will sometimes print a page or two, then it gives me "Support Code 1008" error saying there is no paper. I have to open the lower tray, readjust the paper a bit, hit ok. At that point its about a 40% chance of printing another page or two, otherwise it thinks again and then gives the same error. It makes it almost impossible to print anything more then a couple pages since every few pages is spending a few minutes going back and forth with the printer. Did I get a lemon? Is there something I missed that would make it so the printer can't pick up the paper? Before I return the printer I wanted to try to get some assistance.

If the paper has been loaded correctly and the error persists, additional troubleshooting will have to be done to narrow down the cause of your issue. Please contact our support group using the link below for additional assistance.

Please remove the paper tray and ensure that the paper guides are fitting snug around the paper so that it does not have any wiggle room in the tray, then replace the tray in the printer. Next, please perform a roller cleaning on the unit by following the steps at the link below:

If you still experience difficulty after performing at least three roller cleanings on the unit, the printer will require servicing. Please call or email us at one of the methods on the Contact Us page to obtain your servicing options.

To suppress the misprint prevention message, change the setting as described below. When you suppress the message, the printer uses the paper settings for printing or copying onto the paper in the cassette regardless of whether or not the paper matches these settings.

There's a pecking order when it comes to movies around our house. A very few are worth seeing in a theater, some are definitely rentals, some are worth buying the DVD (or buying a copy on iTunes) and a very few are worth shelling out for a Blu-Ray copy, in which case I always opt for the combo packs that combine Blu-Ray, a DVD and digital copy. Blu-Ray for the full experience, the DVD we usually give away to a friend, and the digital copy goes in the iTunes library. Nowhere in this equation does 3D enter into the calculation, mind you. But what happens when you buy the combo pack and lose the code for the digital media copy?

If you do not know what paper information to set, press the Back button. The previous screen appears, showing the paper size and media type. Check the paper settings and set them as the cassette paper information.

To suppress the misprint prevention message, change the setting as described below. When you suppress the message, the machine uses the paper settings to print or copy on the paper in the cassette, even if the paper does not match the settings.

Nothing was dropped inside and I tried the suggestion to unplug and hit the on button couple of times but no go. I have run out of black ink but don't see why that would produce paper jam error. I have cannon pixma2900 series.

Having the same problem. I did have a paper jam. I got all the paper out of the jam from all three angles. When it takes the paper, it crinkles it up and says no paper. My daughter has a project do thats already late and I'm not sure what to do ..Canon Pixma(mg6821)

I am practically crying right now because your simple advice was so helpful! I have a Canon MG3600 that had a paper jam last weekend. I *now* know how careful to be when clearing printer paper jams, but your simple fix saved me from having to purchase another new printer! THANK YOU THANK YOU THANK YOU

Thank you very much this works on Canon Mg4200 Have been arguing with my husband for weeks as he wanted to buy a new printer as printer was stuck on paper jam and nothing could remove this display Now printer finally works although think it must need realignment as the printing is smudged and patchy but at least we can do something with it now
