A couple of weeks back we reviewed the Samsung CLX-6220FX colour laser multifunction printer. The CLP-620ND, reviewed here, is a single-function printer, based on the same print engine as that machine. It's intended for a small business or a workgroup within a larger organisation.
This is a substantial printer, sitting high off the desk, as its four-colour engine is arranged vertically inside the case. Its overall design, in two shades of grey, is elegant and functional, with the exception of the flip-up paper rest at the back of the output tray. You'd think in a machine this size a stop wouldn't be necessary; its moulded hinge is big enough for the first page of each job to catch on it. It's not enough to disturb the paper flow, but is irritating.
The control panel at the front is simple but sufficient, with a 2-line by 16-character LCD display, a ring of control buttons, with a four-segment, blue LED surround and two further buttons for power and job cancel. There's a large red and green LED indicator for error conditions, too.
Part of the large front panel folds down to become a 100-sheet multi-purpose tray and there's a 250-sheet main paper tray. You can add a second, 500-sheet tray underneath, as an option.
The machine is provided with USB and Ethernet connections at the back and drivers are provided for Windows, OS X, Linux and Citrix. Physical setup is straightforward, as the front panel folds down to access the drum and toner cartridges and the transfer belt, while the top cover reveals the fuser unit. Only the drum and toner cartridges have to be fitted before use.
Samsung rates the CLP-620ND at 20ppm for both black and colour print, and we got closer to this than we did with the CLX-6220FX. Our five-page text print took 28s, giving a real-world speed of 10.7ppm. Coincidently, this was also the speed for the five-page black text and colour graphics document.
When we printed the 20-page text document, the speed increased to 16.2ppm, which is very reasonable for a mid-range colour laser. The machine performs what Samsung calls Real-Time Calibration, which attempts to insure constant colour fidelity, a laudable aim. It does mean, though, that periodically a print job will take longer than normal, because of this automatic adjustment.
Duplex print is standard on this machine, not that usual for a colour laser, and it prints quickly and effectively. Our 20-page document, printed as a 10-page, 20-side duplex job took 2:30, exactly eight sides per minute.
