Impression Products V. Lexmark International: A Victory For Common Sense

A few months ago we reported on a case coming before the United States Supreme Court that concerned recycled printer cartridges. Battling it out were Impression Products, a printer cartridge recycling company, and Lexmark, the printer manufacturer. At issue was a shrinkwrap licence on inkjet cartridges — a legal agreement deemed to have been activated by the customer opening the cartridge packaging — that tied a discounted price to a restriction on the cartridge’s reuse.

It was of concern to us because of the consequences it could have had for the rest of the hardware world, setting a potential precedent such that any piece of hardware could have conditions still attached to it when it has passed through more than one owner, without the original purchaser being aware of agreeing to any legal agreement. This would inevitably have a significant effect on the work of most Hackaday readers, and probably prohibit many of the projects we feature.

We are therefore very pleased to see that a few days ago the Supremes made their decision, and as the EFF reports, it went in favor of Impression Products, and us, the consumer.  In their words, when a patent owner:

…chooses to sell an item, that product is no longer within the limits of the monopoly and instead becomes the private individual property of the purchaser, with the rights and benefits that come along with ownership.

In other words, when you buy a printer cartridge or any other piece of hardware, it is yours to do with as you wish. Continue reading “Impression Products V. Lexmark International: A Victory For Common Sense”

Arch Your Eyebrow At Impression Products V. Lexmark International

When it comes to recycled printer consumables, the world seems to divide sharply into those who think they’re great, and those who have had their printer or their work ruined by a badly filled cartridge containing cheaper photocopy toner, or God knows what black stuff masquerading as inkjet ink. It doesn’t matter though whether you’re a fan or a hater, a used printer cartridge is just a plastic shell with its printer-specific ancilliaries that you can do with what you want. It has performed its task the manufacturer sold it to you for and passed its point of usefulness, if you want to fill it up with aftermarket ink, well, it’s yours, so go ahead.

There is a case approaching the US Supreme Court though which promises to change all that, as well as to have ramifications well beyond the narrow world of printer cartridges. Impression Products, Inc. v. Lexmark International, Inc. pits the printer manufacturer against a small cartridge recycling company that refused to follow the rest of its industry and reach a settlement.

At issue is a clause in the shrink-wrap legal agreement small print that comes with a new Lexmark cartridge that ties a discounted price to an agreement to never offer the cartridge for resale or reuse. They have been using it for decades, and the licence is deemed to have been agreed to simply by opening the cartridge packaging. By pursuing the matter, Lexmark are trying to set a legal precedent allowing such licencing terms to accompany a physical products even when they pass out of the hands of the original purchaser who accepted the licence.

There is a whole slew of concerns to be addressed about shrink-wrap licence agreements, after all, how many Lexmark owners even realise that they’re agreeing to some legal small print when they open the box? But the concern for us lies in the consequences this case could have for the rest of the hardware world. If a precedent is set such that a piece of printer consumable hardware can have conditions still attached to it when it has passed through more than one owner, then the same could be applied to any piece of hardware. The prospect of everything you own routinely having restrictions on the right to repair or modify it raises its ugly head, further redefining “ownership” as  “They really own it”. Most of the projects we feature here at Hackaday for example would probably be prohibited were their creators to be subject to these restrictions.

We’ve covered a similar story recently, the latest twist in a long running saga over John Deere tractors. In that case though there is a written contract that the farmer buying the machine has to sign. What makes the Lexmark case so much more serious is that the contract is being applied without the purchaser being aware of its existence.

We can’t hold out much hope that the Supreme Court understand the ramifications of the case for our community, but there are other arguments within industry that might sway them against it. Let’s hope Impression Products v. Lexmark doesn’t become a case steeped in infamy.

Learning To Reverse Engineer On A Broken Printer

Lexmark Hack

When a Lexmark inkjet printer stopped working, [Mojobobo] was able to claim it as his own. He quickly realized that the machine was flooded with ink and not worth repairing, but that didn’t mean he couldn’t still find a use for it. When he learned that the printer’s firmware was not only upgradable but also unprotected, he knew he should be able to get the printer to do his own bidding.

[Mojobobo] started his journey with the motherboard. The unit still powered up, but it was asking to insert a “duplex module” before it would boot any further. [Mojobobo] first tried to find a way to trick the duplex module sensor, but was unsuccessful. His next step was to search for some kind of serial communications port. He didn’t have an oscilloscope, so instead he used a speaker with a wire probe. In theory, if the wire was pressed against an active serial port, he would be able to hear varying tones through the speaker. Sure enough, he found some interesting tones after probing around some ports next to a “JTAG” label. He looked up some information about the nearby chip and found that it included an SPI bus.

After some internet research, [Mojobobo] learned enough about SPI to have a rough idea of how to use it. Having limited tools available to him, he decided to use his Arduino to try to communicate with the motherboard. After wiring up a simple circuit, (and then re-wiring it) he was able to dump the first 4096 bytes of the motherboard’s boot loader to the Arduino via the SPI interface.

[Mojobobo’s] next steps will be to find a faster way to dump the boot loader. At 9600 baud, he grew tired of waiting after three hours. Once he has the full boot loader he intends to search for a way to bypass the duplex sensor and get the board to finish booting. Then he may just use the printer for its scanning functions, or he might find other interesting uses for it.

Free Linux Computer From A Printer’s WiFi Card

Whether it’s building a 3D scanning system with a Kinect, or using a USB TV tuner dongle for software defined radio, there are a lot of interesting off-schedule uses for commodity hardware. The latest comes from the fruitful mind of [sjMoquin] and a Lexmark N2050 WiFi card that runs Linux.

This build started off with a Lexmark X6570 all-in-one printer available for about $100 USD on eBay. This printer comes packaged with a Lexmark N2050 WiFi card running BusyBox. After soldering a few wires to the USB/UART pins on the N2050, [sjMoquin] had a very cheap but highly useful single board computer running Linux.

There is still a little more work to be done – the WiFi and USB on the N2050 aren’t currently supported. [sjMoquin] and [Julia Longtin] are working on that, so a fully functional embedded Linux board based on a printer’s WiFi card should be available soon. It might be time to hit up eBay for a few of these cards, you know.
