Question: What should I do about an error code 033505 on my three-year-old Epson WF7210 sublimation printer?

Answer: Thank you for reaching out to us! At BCH Technologies, we're always here to assist and appreciate your continued support and engagement, especially on our YouTube channel. Your feedback is invaluable in enhancing our expertise.

Regarding your Epson WF7210 encountering the error code 033505, it sounds like your printer is experiencing a specific issue typically not seen outside of the manufacturing process. The error code "033505" indicates an "ILS Empt jig error," which implies an issue that shouldn’t occur post-manufacture, suggesting a possible firmware corruption.

In cases like this, the error usually points to the firmware being stuck in a mode ("set jig") that needs resetting. Here's how you can approach fixing this issue:

1. Firmware Update: Sometimes, updating the firmware can resolve this by overwriting the corrupt area on the chip. Visit Epson’s official website to download the latest firmware for your specific model.
2. Roll Back Firmware: Similarly, you can roll back to a previous version of firmware.
3. Replacing Mainboard Chips: If a firmware update doesn't resolve the issue, it might be necessary to replace the chips on the mainboard. This involves removing the faulty chips and copying known-good binary files onto the new chip.
4. Mainboard Replacement: Alternatively, if the above steps seem too daunting or if the printer still fails to operate correctly, purchasing a new mainboard might be the best route. You can find replacement mainboards on platforms like eBay.

Addressing printer issues can often be complex due to the nature of the problems. For example, a simple ink system clog could require detailed unclogging procedures, whereas an inactive printer might need a full ink system service. Moreover, something as common as a paper jam can have numerous causes, turning its resolution into a running joke around the office.
