The establishment of the unit ran perfectly, it is connected through the network with two computers. He works the print jobs in succession. The device is in use in the company and has been printed about 5,000 pages. The toner had to be renewed in the meantime. Copy goes smoothly, insert or have them collected, and within a few seconds the copy is made. As for the printing and copying, I had been a better device. Negative, I notice the quality of the materials used. The hinges of the device are made of plastic (like the rest of the system), which can cause this could break sometime and the attachment then shaking loose to himself. This could be solved better with metal hinges. Who very often need to copy bulky pages and the tray can not be used, or a lot of scans, has an increased risk of hinge breakage. I recommend those but then a more sophisticated model. For those who print a lot and little scan, I would recommend this device without reservation.
