Remember: When in doubt, replace the mainboard. But first, invest 20 minutes in trying these firmware recovery steps. In most cases, a digital ghost in the .fls file is all that stands between you and a perfectly functional monochrome laser printer.
Below are four methods to resolve this error, ranging from simple software resets to advanced hardware repairs.
The problem is most prevalent when using third-party, remanufactured, or refilled toner cartridges. The original Samsung firmware often includes a feature that rejects non-authentic cartridges to protect the device. Forcing a firmware update is a method to bypass this restriction, allowing the printer to function with more cost-effective consumables. Fix Ml1660 V1.01.00.30.fls
A small command prompt window will open, showing a progress bar or a series of dots indicating data transmission.
Flashing the wrong .fls file (e.g., from an ML-1640 or ML-1860) will brick the printer permanently. Remember: When in doubt, replace the mainboard
Like most entry-level laser printers, the Samsung ML-1660 and its siblings (like the ML-1665) use smart chips on the toner cartridge. These chips track the number of pages printed and forcefully disable printing once the page threshold is reached, even if the cartridge still contains usable toner powder.
: Once the printer restarts, the toner counters should reset to 100%. If you applied a chip-fix, you can now cover the toner cartridge chip with tape to continue printing. Troubleshooting Common Errors Below are four methods to resolve this error,
Ensure your computer is connected to a stable power source. A power outage during this process will corrupt the printer's memory.
Modifying official firmware immediately voids any manufacturer warranty from HP/Samsung Support Integrity Risks:
If you value the ML-1660 for its compact size, cheap toner (MLT-D105L), and durable paper feed mechanism, investing time in the methods above is worthwhile. Start with the hard reset, escalate to manual re-flashing, and only replace the mainboard as a last resort. With patience and the right .fls file, your Samsung ML-1660 will print again.
Flashing the printer with a custom firmware (fix firmware) is a permanent solution to bypass the need for expensive, chipped toner cartridges. The Ml1660 V1.01.00.30.fls is specific firmware designed for printers running the V1.01.00.30 version. What is Fix ML1660 V1.01.00.30.fls?
