How to Reset the Toner of Samsung ML 1640 Printer with Firmware V1.01.00.91

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 printer has a counter that tracks the number of pages printed and prevents the use of the toner cartridge after a certain limit. To fix this issue, you need to reset the counter and make the printer recognize the toner cartridge again.

In this article, we will show you how to reset the toner of Samsung ML 1640 printer with firmware V1.01.00.91, which is one of the older versions of firmware that can be reset using a simple method. If you have a newer version of firmware on your printer, such as V1.01.00.83 or higher, this method will not work and you will need to use a different method or buy a new toner cartridge with a chip.

Steps to Reset the Toner of Samsung ML 1640 Printer with Firmware V1.01.00.91

• Turn off the printer and disconnect the power cord.

• Open the front cover of the printer and remove the toner cartridge.

• On the back side of the toner cartridge, you will see two metal contacts that are connected to two wires inside the cartridge. These are the terminals that communicate with the printer and store the counter information.

• Use a small piece of wire or a paper clip to short these two contacts together. This will erase the counter information from the toner cartridge.

• Reinstall the toner cartridge into the printer and close the front cover.

• Connect the power cord and turn on the printer.

• Press and hold the power button for about 15 seconds until the green LED flashes three times and then stays on. This will reset the printer and make it recognize the toner cartridge again.

• Turn off the printer and wait for about 10 seconds.

• Turn on the printer and print a test page. If the print quality is good, you have successfully reset the toner. If not, you may need to change the toner cartridge.
