Troubleshooting an HP DesignJet T610: Toner Recognition and Firmware Issues

In the world of architecture and design, having access to a large format printer can be a game-changer. For a group of resourceful architectural students who managed to acquire an old, non-functioning HP DesignJet T610, this printer was not just a piece of equipment; it was an opportunity to learn, create, and save on costs. However, their journey to resurrect this printer was not without its challenges.

The Initial Repair: Replacing the Carriage Belt

The first step in their journey was to fix the printer's carriage belt. The previous owner had informed them that this was the only issue plaguing the machine. Changing the carriage belt was akin to changing a printhead, according to their sources. With the help of comprehensive YouTube tutorials, they successfully replaced the belt, and the printer's print heads moved normally upon startup.

Toner Troubles: PK Toner Not Recognized

After the carriage belt replacement, a new problem surfaced: the printer would no longer recognize the PK Toner (black toner). Initially, everything seemed fine upon booting the printer, and they were even able to initiate a print job without errors. However, mid-print, the printer demanded that they reload the PK Toner because it was empty. They suspected the old, fake toner that came with the printer was to blame, so they ordered a new, genuine HP toner. To their dismay, the printer continued to insist that the toner was empty, despite being fresh out of the box. All other toners were recognized without issue.

Exploring Hardware Troubleshooting

Naturally, their initial thought was that their amateur repair job might have caused this issue. However, the carriage belt replacement should not have affected toner recognition since it does not involve any components related to toners. So, where should they look for potential hardware problems?

One theory they came across was that the printer's firmware might be the culprit, as the printer had been inactive for an extended period. Attempting to update the firmware, though, presented a challenge. The printer was no longer recognized by their Windows 10 computer, with an error potentially obstructing the signal between the two devices.

Possible Firmware Workaround

Desperate for a solution, they wondered if there was a way to brute force the software, perhaps even to bypass the toner error and print without the problematic toner. Unfortunately, no immediate workaround was apparent.

Printer's Refusal to Start

Frustrated and disheartened, they allowed the printer to sit idle for a while. When they finally attempted to start it again, a new issue emerged. The printer now displayed an error message, insisting that it needed to be restarted or that they should contact HP support. Given their previous experience with the printer, they were understandably hesitant to follow this recommendation.

Seeking a Last-Minute Solution

Realizing that they had invested significant effort into repairing the printer, they were reluctant to give up without exploring every possible avenue for a solution. They reached out to seek advice and assistance, acknowledging that their situation seemed dire.

A Response and a Resolution

One user responded with their experience, revealing that their issue had been related to the printer's software. Unfortunately, they couldn't resolve it due to the absence of compatible hardware for setting up a Windows 2000 server, which was needed to service the firmware and get the drivers working. Their attempts to use a virtual machine were also unsuccessful due to USB compatibility issues.

A Suggestion for Obsolete Hardware

For those who might have obsolete hardware on hand, they recommended attempting to set up a Windows 2000 server with the appropriate OS and drivers. However, they cautioned that even if this were successful, communication with a modern OS, such as one from 2023, might still pose problems.

The Takeaway

The journey of these architectural students with the HP DesignJet T610 is a testament to the challenges one might encounter when attempting to resurrect older equipment. While their specific issues revolved around toner recognition and firmware updates, it underscores the importance of considering both hardware and software factors when troubleshooting printer problems.

In the ever-evolving world of technology, compatibility can be a significant hurdle. When dealing with older devices, like the HP DesignJet T610, users may encounter obstacles that are difficult to overcome without the necessary hardware and expertise.

For those who find themselves in a similar situation, it's essential to explore all available resources, seek advice from the community, and, if possible, attempt workarounds like setting up legacy hardware. However, one should also be prepared for the possibility that some older equipment may not seamlessly integrate with modern systems, which could limit their functionality.

In the end, while the journey may not always result in a complete resolution, the knowledge gained and the experiences acquired can be invaluable. These students' endeavor serves as a reminder that challenges can lead to growth and expertise, even when the outcome isn't exactly as planned.
