Bricked Epson printers make a strong case for user repairability

Epson gained some scrutiny on Twitter in recent weeks after the company disabled a printer that was otherwise working fine, leading to accusations of planned obsolescence. Epson knows its printers will stop working without simple maintenance at a predictable point in the future, and it knows that it won’t be cost-effective for many owners to send their home printers in for service. So why not build them to be user serviceable in the first place?

The inciting post from @marktavern mentions that his wife was unable to use her “very expensive Epson printer” after an end-of-service error message appeared.

This isn’t anything new for Epson printers, sadly. Reports going back several years mention an infamous error message that reads “parts inside the printer have reached the end of their service life.” Epson confirmed to The Verge that the error is related to the printer’s ink pads, which had likely become saturated through extended use and were now at risk of spilling into the rest of the printer mechanism.

In a recently updated support document, Epson offers several solutions to resolve the problem. These include sending the printer into Epson to replace the ink pads or having a local certified technician do it. Previously (via Wayback Machine), just before the issue gained notoriety, Epson conceded that “repair may not be a good investment for lower cost printers because the printer’s other components also may be near the end of usable life.” It then added that “most consumers who are out of warranty elect to replace a lower-cost printer when they receive an end of life service message.“ Now, Epson suggests the feel-good option of sending the bricked unit in for recycling.

Epson does offer customers in North America a free one-time-only Maintenance Reset Utility that lets you temporarily ignore the error message for a “limited time” in order “to complete existing print run needs.” But this is restricted to Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP users, with no official offering for Windows 11 or Mac. You can purchase additional reset keys from less than reputable third-party websites that will typically charge you $9.99 for the service — not that Epson will be happy with you doing so.

Exasperated users found other ways to keep a printer operational after suffering this error, such as manually replacing or cleaning the ink pads themselves. The company’s ink pads seem to vary slightly by model, but there are plenty of video tutorials available that document the process. Frankly, all these tasks look fairly simple to perform but none are officially endorsed by Epson.

For its part, Epson says the ink pad issue is rarely encountered by most customers and only affects very heavily used printers, printers used for several years, or consumer printers used in commercial environments. “Most print users will never receive this message under intended use scenarios,” said Merritt Woodward, a representative for the printer company. “It is directly dependent on the printer model, frequency, usage conditions, and type of printing over time.”

The company also contends that there’s a safety issue to consider. “The printers are designed to stop operating at the point where further use without replacing the ink pads could create risks of property damage from ink spills or safety issues related to excess ink contacting an electrical component,” reads the Epson support page. This sounds reasonable as Epson doesn’t want to be held responsible for property damage. But it’s also an admission that the hardware has a known expiration date that can be avoided with maintenance.

This ink pad scenario is a prime example of why so many consumers are fighting for the right to repair their own hardware. Epson’s endorsed solutions require you to pay to service the printer or replace it entirely, taking money out of your pocket and placing it into its own despite the existence of effective DIY solutions. Instead, Epson should design the ink pads to be user serviceable and sell kits to consumers to either clean or replace them. But Epson has nothing to lose and everything to gain by continuing the status quo, and that’s a bad deal for its customers as well as the environment. (Even recycling schemes are rarely 100 percent efficient.)

Epson is hardly the only printer manufacturer to come under scrutiny for anti-consumer practices, with HP making the news back in April 2022 for remotely disabling printers for customers who canceled their Instant Ink subscription. Canon also became a victim of its own business tactics earlier this year when the chip shortage resulted in cases of Canon printers being unable to recognize its own officially branded ink cartridges. It goes to show that manufacturers can always find new ways to make us loathe needing to use an inkjet printer.

Canon printers now think Canon’s own toner is fake

Printers are the worst. They’re unreliable, they guzzle reportedly $12,000-a-gallon ink, and their manufacturers have been known to use dirty tricks, scare tactics, and DRM to strongly encourage you to buy cartridges exclusively from them. But Canon is now getting a taste of its own medicine. Some of Canon’s own toner cartridges are now being detected as fakes — and they’re forcing the company to teach customers how to bypass its own DRM (via Techdirt).

According to Canon’s own support website (Europe, Germany), the company is “currently facing challenges in sourcing certain electronic components that are used in our consumables for our multifunction printers.” In other words, Canon’s been hit by the great chip shortage, too — only the components Canon’s missing aren’t powering video game consoles or your Tesla’s USB port; they’re the DRM for its own toner cartridges.

But wait, there’s a simple solution, says Canon! See all our warnings about how your toner cartridge might be “malfunctioning”? Ignore them. Just hit the close button, and you’ll be good to go:

If you’re hoping to experience an approved-bypassing-of-DRM on your inkjet home printer, though, you might be out of luck — we’re only seeing Canon’s big workplace multifunction printers (MFP) on the list of “affected models” at Canon’s website.

As Techdirt points out, Canon is currently facing down a lawsuit involving some alleged behavior that seems even more egregious than the typical DRM tricks: Queens resident David Leacraft claims his Canon Pixma All-in-One doesn’t even scan documents unless it has ink. We checked, and Canon hasn’t yet issued a response to that lawsuit in court, but multiple posts on Canon’s official support forums suggest that the ridiculous restriction is real.

“The PIXMA MG6320 must have all ink tanks installed in the printer and they must all contain ink in order to use the functions of the printer. Replacing the empty ink tank with a new ink tank will resolve this issue. There is no workaround for this,” wrote one rep in 2020.

“If you are getting a ‘Ink Out’ error, you will not be able to use the unit until the ink is replaced,” they wrote in 2016.

The lawsuit is seeking class action status, and we’ll let you know if it goes anywhere.

Sadly, some of us still need printers (though not always for signing and scanning documents, as I recently discovered). Here’s our guide on how to choose one if you can’t get out of it.

16-Year-Old Security Bug Affects Millions of HP, Samsung, Xerox Printers

Details have emerged about a high severity security vulnerability affecting a software driver used in HP, Xerox, and Samsung printers that has remained undetected since 2005.

Tracked as CVE-2021-3438 (CVSS score: 8.8), the issue concerns a buffer overflow in a print driver installer package named “SSPORT.SYS” that can enable remote privilege and arbitrary code execution. Hundreds of millions of printers have been released worldwide to date with the vulnerable driver in question.

However, there is no evidence that the flaw was abused in real-world attacks.

“A potential buffer overflow in the software drivers for certain HP LaserJet products and Samsung product printers could lead to an escalation of privilege,” according to an advisory published in May.

The issue was reported to HP by threat intelligence researchers from SentinelLabs on February 18, 2021, following which remedies have been published for the affected printers as of May 19, 2021.

Specifically, the issue hinges on the fact that the printer driver doesn’t sanitize the size of the user input, potentially allowing an unprivileged user to escalate privileges and run malicious code in kernel mode on systems that have the buggy driver installed. now

“The vulnerable function inside the driver accepts data sent from User Mode via IOCTL (Input/Output Control) without validating the size parameter,” SentinelOne researcher Asaf Amir said in a report shared with The Hacker News. “This function copies a string from the user input using ‘strncpy’ with a size parameter that is controlled by the user. Essentially, this allows attackers to overrun the buffer used by the driver.”

Interestingly, it appears that HP copied the driver’s functionality from a near-identical Windows driver sample published by Microsoft, although the sample project in itself doesn’t contain the vulnerability.

This is not the first time security flaws have been discovered in old software drivers. Earlier this May, SentinelOne revealed details about multiple critical privilege escalation vulnerabilities in Dell’s firmware update driver named “dbutil_2_3.sys” that went undisclosed for more than 12 years.
