The Samsung ML-3650 printers are based on a Samsung 35-ppm, 1,200-dpi engine. These machines are one of Samsung’s first attempts to compete head-on with HP for high-speed business printers. The warm-up time from power on is 40 seconds, and the time for first page out is nine seconds or less. The fuser assembly and various rollers are rated for 150,000 pages.

The machines based on the ML-3560 engine are the:

• ML-3560
• ML-3561N
• ML-3561ND

As with the ML-6060, these cartridges are at the same time deceptively easy and deceptively difficult to remanufacture. These cartridges have to be taken apart and put back together in a certain way. If you do not, the cartridge will at some point fall apart with parts coming out all over, and you will be left wondering where they went. Trust me.

There are two cartridges available for this series. The ML-3560D6 cartridges are rated for 6,000 pages at 5 percent coverage, and the ML-3560DB cartridges are rated for 12,000 pages.

In addition to an adhesive sealing strip, these cartridges also use a shipping lock. This lock keeps the developer roller away from the drum, and helps prevent the developer roller from getting a flat spot during storage. It is very important that the shipping lock be installed.
