The Fix Generator V 1.1 for the Samsung SCX-3405 is a third-party firmware modification tool designed to bypass the printer's toner chip requirements. By applying this "fix," users can refill original cartridges or use cheaper compatible cartridges without the printer blocking them due to an "empty" or "missing" chip. Key Functions of the Fix
Chip Bypass: Disables the printer's need for the CRUM (Customer Replaceable Unit Monitor) chip on the toner cartridge.
Counter Reset: Automatically resets the toner counter to 100% every time the printer is restarted.
Cost Reduction: Allows for direct toner refills of the MLT-D101 cartridge. Preparation for Using a Fix Generator
To generate a correct fix, you typically need specific data from your device, as fixes are often locked to a printer's unique identifiers:
Serial Number: Found on the back of the printer or in the configuration report.
Firmware Version: Must be verified before applying any patch; incompatible versions can "brick" the printer. CRUM Number: The unique ID of the current toner chip. How to Print Required Reports
If the printer is blocked, you can use Tech Mode to print these details:
Configuration Report: Press and hold the Stop/Clear button for 4–5 seconds until the LED flashes, then release.
Supplies Information (CRUM): Press and hold Stop/Clear for about 15 seconds until the LED stays solid green.
Tech Mode Access: Quickly press + + Stop - - Stop Stop. Navigate using + until "AA" appears, then press Start twice to print all reports. Critical Risks and Official Support
Using non-official "fix" firmware carries significant risks:
Firmware Corruption: Interrupted updates or incorrect versions can cause the printer to freeze or fail to power on.
Warranty Voidance: Applying third-party firmware typically voids any remaining manufacturer warranty.
Official Alternatives: For standard software issues like scanning errors after Windows updates, HP (which now supports Samsung printers) recommends downloading the Samsung Easy Document Creator from a similar model's page if the SCX-3405 page lacks it. fix generator v 1 1 samsung scx 3405

The fix generator v 1.1 for the Samsung SCX-3405 refers to specialized firmware reset software designed to bypass the printer's chip-based protection, allowing you to refill toner cartridges without purchasing expensive new ones. By applying this "FIX" firmware, you permanently disable the printer's need to read the CRUM chip on the cartridge, resetting the toner level to 100% every time the printer restarts. Understanding the Samsung SCX-3405 Fix Firmware
Samsung printers like the SCX-3405 use chips in their MLT-D101 cartridges to track the number of printed pages. Typically, after approximately 1,500 copies, the printer blocks further printing and prompts you to replace the cartridge, even if there is still toner inside. The fix generator creates a custom firmware file (often version V3.00.01.xx) that removes this software block. How to Use the Fix Generator V 1.1
To successfully reset your printer, you must first gather specific data to ensure the firmware matches your hardware exactly. 1. Prepare Your Printer Reports
You need the Serial Number, Firmware Version, and CRUM Number.
Configuration Report: Hold the STOP/CLEAR button for about 4–5 seconds until the LED flashes once, then release.
Supplies Information Report: Hold the STOP/CLEAR button for about 15 seconds until the LED stays green, then release.
Tech Mode (if blocked): If the printer is already locked, press [+] [+] [STOP] [–] [–] [STOP] [STOP] on the panel. Navigate until you see AA and press START to print a detailed report. 2. Applying the Fix
Once you have the custom FIX_xxxxxxxxxxx_SCX3405_V3.00.01.xx.hd file:
Connect the printer to your PC via a high-quality USB cable.
Extract the archive containing the fix and the usbprns2.exe utility.
Drag and Drop the firmware file onto the usbprns2.exe application.
Wait: A black command window will appear and close. The printer will show an "updating" status. Do not disconnect power during this process (approx. 1.5 minutes) as it could damage the device.
Restart: The printer will reboot automatically and the status light should turn green. Final Maintenance Steps
After a successful firmware update, you must remove or tape over the chip on the toner cartridge. If you insert a cartridge with a new chip, the printer might re-lock itself; keeping your original "key" chip safe is often recommended for future troubleshooting.
