If you have a Samsung ML 1640 laser printer with the starter toner cartridge (that was in it when you bought it), you may encounter a problem when you try to refill it or replace it with a non-original cartridge. The printer may stop working and display a "Toner Exhausted" message on the red LED.
This is because the starter toner cartridge does not have a chip that can be reset, unlike the regular toner cartridges that you can buy from Samsung or other suppliers. The chip is a small device that keeps track of the number of pages printed and signals the printer when the toner is low or empty.
Fortunately, there is a way to reset the starter toner cartridge and make your printer work again. You will need to update the firmware of your printer to a newer version that does not check for the chip. This will allow you to use any toner cartridge, whether it is original, compatible, or refilled.
Before you proceed, make sure that you have a USB cable to connect your printer to your computer, and that your printer is turned on and ready. Also, make sure that you have downloaded the latest firmware file for your printer from Samsung's website. The file name should be something like "ML-1640_V1.01.00.91.exe".
Congratulations! You have successfully updated the firmware of your printer and reset the starter toner cartridge. You can now use any toner cartridge you want, without worrying about the chip or the page count.
If you encounter any problems during or after the firmware update process, here are some tips that may help you:
