This usually starts with V1.01.01.xx or V1.01.02.xx (e.g., V1.01.01.12 or V1.01.02.01 ).
The printer will program for 1–2 minutes and then restart automatically.
Keep both pressed for about 2 seconds, then release them together. The printer LEDs should change color or blink, indicating it is waiting for firmware. Step 4: Flash the Firmware
Release both buttons simultaneously after 2 seconds. The LED indicator should turn solid green or orange, signaling it is ready for a firmware transfer. Step 4: Execute the Flash Click and hold the custom .hd firmware file. Drag and drop it directly on top of the usbprns2.exe icon.
Hold it longer (around 10–15 seconds) until the light stays solid green, then release to get the Supplies Information Report.
Check if the tape is completely covering the contacts. If the light remains red without a chip, check your configuration report again to verify if the firmware update actually registered. The Printer is Unresponsive ("Bricked")
Place a small piece of directly over the metal contacts of the chip. This permanently isolates it from the printer's reading pins. Re-insert the cartridge and close the cover.
Drag and drop the .hd file onto the usbprns2.exe file (usually included in the fix package).
Some sources discuss a direct software reset, but this is generally less effective and more risky than a firmware fix. It involves running an executable like usbprns2.exe or similar tools that directly interact with the printer's memory. This method is highly dependent on having the exact correct version for your printer's firmware and often fails, potentially causing more issues.
The phrase "676 link" often refers to specific file archival directories or generator tools used by firmware developers to package modified .hd firmware files.
Ensure your computer is connected to a stable power source (a laptop with a full battery or a desktop on a UPS is preferred). Step 2: Extract the Firmware Files
Extract the archive and drag the firmware file (often with a extension) onto the executable tool (like usbprns2.exe Wait for Reboot:
Specific release builds or forum thread archives where original fix files are hosted.
Place a piece of non-conductive tape (opaque scotch tape or electrical tape) completely over the metal contacts of the chip. Reinsert the cartridge into the printer and close the door. Verifying the Success of the Reset
A: Check the USB cable, use a rear USB port, and ensure you are in "Force Download Mode". If you'd like, I can:
You must generate or find a firmware fix specifically matching your printer's internal data. Using a file meant for another version will cause failure. Step 1: Collect Your Printer's Data
A modified firmware file overwrites the printer's onboard logic. It instructs the printer to always read the toner level as 100%, ignoring the physical state or presence of a cartridge chip. Prerequisites: Finding Your Printer's Exact Data
