How to unlock a samsung ml-1640 laser printer

The samsung ml-1640 printer has been made to fit in modern offices. Its modern size takes up very little room and leaves a lot of space for other office appliances.

We usually recommend it if you want to save on toner, since it uses 30% less product in the saving printing mode, and still shows good printing quality on your paper sheets. It’s also very easy to use, and you can add pages or install toner cartridges in it without having any problems.

This printer is compatible with several different operating system, such as windows, a few linux versions, and the mac 10.3-10.5 ones. It’s very resistant and can yield up to 5,000 pages a month.
