So far, 50533 people have contacted their printer manufacturers to complain. Follow the instructions on this page and then click here to be counted when you're done.

Like us, many people dislike the idea of tracking information embedded in every color document they print. Several people have called up their printers' manufacturers to complain and to ask how they might turn off the tracking information. At least one person (who wishes to remain anonymous) was subsequently paid a visit by the United States Secret Service who asked him a series of questions about why he wanted to turn off the dots.

There is no law that requires printer manufacturers to include these dots. Several color printers do not seem to include them at all! There is nothing suspicious or criminal about wanting to privately or anonymously produce color documents. In fact, the ability to speak anonymously is an essential part of our democracy! We have every right to demand color laser printers without this "feature." We have every right to demand that our printer manufacturers to fix their devices. We shouldn't need to choose between our privacy and color print outs.

Let's join together to call our printer manufacturers and demand that they tell us how to turn off the tracking dots. Let's stand up to bullying and interrogations by the U.S. Treasury Department and Secret Service of others who have done the same. If we all stand up together, we can send a strong message that there's nothing wrong with demands to print privately. Together, we can make it more difficult for groups like the Secret Service to bully individuals who do so.

Carefully read the information in this next section and call your printer manufacturer today!

Before you call

Make sure that your printer actually prints tracking codes. The printers that are known to do this are color laser printers -- not color inkjet printers, and not black-and-white laser printers. If you call a printer manufacturer to ask about these other printers, you are likely simply to be told that the tracking technology is not part of your printer.

You can look to see whether your color laser printer is on EFF's list of printers that print dots. That list is not complete, so you might want to double check a printer for yourself if it's not on the list.

You can check for yourself whether your printer prints tracking codes by shining a blue light on a page you printed in color. The dots will appear black and be repeated across the entire page. They're very small, but you should be able to see them if you look closely. You can read more about how to do this on the EFF website.

Questions you might ask your printer manufacturer

  • How can I disable the forensic tracking codes that my printer prints?
  • If it's currently not possible to do this, is there a software update for my printer that would let me disable the tracking codes?
  • If there's no such software update available yet, will you develop a software update to allow me to disable the tracking codes?
  • Do you produce any color laser printers that don't print forensic tracking information? Is it possible to exchange my printer for a similar model without forensic marking features?
  • Why did you design this printer to print tracking information? Are you planning to do this in future printer models?
  • Does my printer include any other hidden features that make it easier for someone to track documents I produce back to me? Are you planning to include such features in future printer models?
