Samsung CLX-2160 Color Laser MFU


After a long research online, and an unsuccessful attempt to start a good cooperation with the Canon local store, I was compelled to abandon my plan of getting a Canon MF4140 unit and continue my search for a good multifunctional unit. My requirements were that it should be a laser printer with scanner and a built in duplexing unit. For the requirements, the Canon MF4140 was perfect. BUT, the authorized dealer offered an insultingly poor customer service.
After the bad experience, I reviewed the requirements for my new MFU, and was convinced by the Samsung CLX 2160, that I actually do not have to have a duplexing unit, and that I can trade auto duplexing for the option of color printouts. So, the long search of a laser printer ended. I settled for a color laser printer with a built in scanner, with no network card, and no duplexing unit.


The Samsung CLX-2160 is a solidly built machine, weighting almost 17kg, and measures approximately 350x350x400mm. It is actually quite large, and I don't understand why Samsung opted for a semi-open paper tray. This is probably the only design feature I do not like on this printer. Other than this, it is a nicely designed piece of equipment. The colors are soothing but not too boring, and it is a nice item to put on your desk, that is, if your desk can handle its weight and size.




The CLX-2160 theoretically prints 16ppm b/w, and 4ppm color. This of course means that it is a multipass color printer, but a very quiet one. Actually, the only sensible difference between a color and grayscale printing is that the sheet comes out a bit later than a grayscale print. There is no extra noise, no extra clicks, which is very good if you use the printer next by. The speed of grayscale printing is OK. Not to slow, not super fast. This is of course, a matter of choice. For the 220 euros it costs, we should not expect a ninja. Compared to my previous, theoretical choice of the Canon MF4140, which prints 30ppm, the Samsung really is slow, but it offers something that no fast and affordable MFU can- COLOR printouts.
The color printouts, contrary to many reviews I read, is impressive. The colors are saturated, resolution is very good and there are no noticeable inconsistencies in the color distribution. Of course, it is not as good as a photo printer, but it will definitely do the job if you want to print some pictures, color graphics, and of course, black text. Feed a photo paper to it you may even be surprised of the quality color printouts.
Another cool feature is the option to print directly off your USB stick. The USB port is conveniently positioned so it will not be in the way during printing. You can also scan directly to the USB stick without the assistance of a PC. The LCD and the control panel are easy enough to handle, but I would like to see an option of scanning directly to the PC by simply pressing a button on the control panel. In order to access the scanner, you will have to use the program that comes with the printer drivers. It is not a bad program, but it would be better if Samsung figured out a way to have the scanner detectable as a separate piece of hardware. Nevertheless, it definitely does the job, and it is faster than my Epson Perfection 1620 which I bought for 180 euros a few years ago.


As many other printers, Samsung also ships this unit with starter toners. The specified capacity of 1500 copies in 5% coverage did not come true for me. Perhaps due to my combined printing of text and graphics. I printed out about 700 pages when the printer stopped printing and asked for a new toner. With a bit of playing around I managed to squeeze out another 100 pages of text and graphics. When I come to think of it, I did not save a lot of money with it, as a replacement toner with a capacity of 3000 pages costs about 40 euros. The color toners also are starter toners, and specified to last about 1000 pages. I give them a lifespan of no more than 700 pages. When time comes to replace them, it is a very easy task. The toners are color coded, and also made in such a way that even if you are color blind, you will never fit a cyan toner into a magenta slot because the toner boxes have plastic "sticks" which prevent any mistakes. This is a smart move from Samsung. Changing the toners is a simple pull-out, push-in deal. It literally takes seconds to replace a toner. Their price is good because there are no rollers or gears on the toners. They are simple plastic cylinders, only containers for the expensive dust. The printing mechanism is designed to last for about 30-40.000 copies, which in my opinion, is more than enough for several years of printing in a small office or home environment.
The printing experience, when printing double sided, can be frustrating if the paper is wet. I had to scrap some double sided printouts as the printer pulled in several sheets at once, and messed up the order of pages. Once I placed a brand new stack of paper, it worked perfectly. It can print hundreds and hundreds of pages... but it can only print 150 at a time as Samsung designed a small paper tray for this printer. For a multifunctional unit that even comes with optional network card, a paper tray of only 150 pages is really a joke... and not a funny one if you want to print a lot. But again, the price helps to put a blind eye to these inconveniences.
In summary, the Samsung CLX 2160 will not knock you off your feet with its speed, functionality, quietness or capacity. But for the 200 euros it costs it is deffinitely a very good choice, and a wise investment. You will definitely not find a better option in the color laser segment. It's good looks, the relative ease of use and cheap consumables make this unit a best buy for anybody who wants an all in one cheap laser printer. The color option with the CLX 2160 literally comes for free, as there are printers with the same functionality, same price, and only offer fast grayscale printouts, like the Canon MF4140.
I recommend this unit for home and small office use.

HP Compaq 6820s Laptop review


I wrote this text for Cnet since there was no review for this model, and decided to post it on my blog also. (http://reviews.cnet.com/laptops/hp-business-6820s-core/4864-3121_7-33032689.html?messageID=10005602&tag=mncol)
First things first, its a Pentum Dual Core T2410 (2Ghz, 1MB cache), 2GB ram, 250GB SATA drive, DVDRW DL, 3x USB2.0... it has plenty of other stuff... but read on please.






This is a solid machine for the $860 I paid. It is difficult to find a 17" laptop under $1000. My 6820s came with a DualCore T2410 CPU (2GHz and 1MB of L2 cache). It has 2GB of RAM which will be suitable for any office or home use. With its 250GB hard drive, it can store plenty of files, music and movies. The ATI Mobility Radeon 1350 produces a good picture, with plenty of details and good saturation of colors. It may not be the best choice for the modern day games, but I am more than satisfied with its performance for the work I need. The LCD has a solid 1440x900 native resolution, which is unusually high for this price range. The 6820s comes with the standard 56K modem, an Intel 10/100 LAN card, a Broadcom a/b/g card, and even has a built in Bluetooth, a bit unexpected in this price range. Its battery is a 6-cell Li-Ion pack, which can allow you mobility for up to 3.5 hours. Of course, this varies greatly on what you do, but it will definitely be enough to watch a movie, or browse the net and type emails for at least 2.5 hours.
The HP Compaq 6820s is classically elegant and well built, as expected for a Compaq machine. The plastics give a comfortable feel and it does not look cheap as it is the case with some other laptops. For instance, my old Toshiba M35x looked cheap from the day I bought it, even though I paid $1200 for it. Although the LCD is impressively large, the plastic back does not bend too much, again, as it does in my 15” Toshiba. But it is not as tough as it is on my 15.4" HP 530. Non the less, it is a well designed, well built housing. The size of the chassis allows for a full size keyboard which is a welcomed improvement after years and years of using a laptop without a numeric keyboard. This was especially frustrating when I had to type in numbers and when I played Civilization. That frustration is gone with the 6820s. No more mistypes, no more wrong moves in Civ. Life is good now.
The down side, as with the HP 530, is the somewhat cheap look-cheap feel to the keyboard. The keys are large enough and comfortable to type long texts, but I would like to see a softer feel keyboard on the 6820s. Compared to the Toshiba M35 keyboard, this one is a poorly made keyboard for my taste. Technically, its flawless. The touch pad is a good match for the size of the screen, and it is also sensitive. Its keys are soft and smooth, without the cheap clicking found in other cheap laptops, such as the HP530 and the Toshiba M35. But still, not as good as the HP nx6110 has. I’d say that the 6820s touch pad is between the HP 530 and the nx6110. The keys are 530-shaped, but feel a bit like nx6110. Not too bad of a touchpad, but not too good either.
Performance-wise, the 6820s worked as I expected, a bit faster than my HP 530 but not impressively fast.
Here are the details according to PassMark's Performance Test 6.1.

HP 6820s
CPU: T2410 2Ghz, 1MB cache. PassMark 281.7
Graphics: 2D=39.0fps; 3D=18.4fps (Complex 3D=18.7fps)
Memory PassMark 62.8
Hard Disk PassMark 66.5
Overal System Performance: 492.7

HP 530
CPU: T2050 1.6Ghz, 2MB cache. PassMark 204.3
Graphics: 2D=28.4fps; 3D=16.0fps (Complex 3D=6.2fps)
Memory PassMark 54.0
Hard Disk PassMark 61.6
Overal System Performance: 411.6

Toshiba M35x
CPU: Celeron M 1.5Ghz, 512kb Cache. PassMark 86.7
Graphics:. PassMark 2D=28.1fps; 3D=6.9fps (Complex 3D=4.62)
Memory PassMark 48.1
Hard Disk PassMark 26.0
Overal System performance: 217.7

Both HP laptops are in the same price range. I paid the same amount for both, only the HP 530 is a year old now. The performance of the 6820s T2410 CPU is obviously faster than the T2050. Actually comparing the figures, the T2410 does as much as the T2050 and the Celeron M put together. This is worth noting! The ATI performed better than the Intel 945GM, but not dramatically better. The greatest and most dramatic performance gain is in the reproduction of complex 3D graphics, and an expected increase in 2D reproduction. This only means that on average, the ATI is just about enough to feed the 1440x900 17” LCD. The RAM performance is OK, nothing marvelous, but still better than the HP530. The 6820s gains only due to its capacity of 2GB. The hard drive of the HPs are both 5400rpm SATA drives. The performance is expectantly similar, and again, the 6820 gains a plus due to its impressive size for the price range.
In summary, the 6820s performs good. It would perform even faster if it could get a faster RAM and a faster hard drive. As it is, the overall performance of 492.7 is not much faster than the HP530’s 411.6. If you take in consideration that the T2410 performed as much as the Celeron M and the T2050 put together, then it is easy to conclude that somewhere, the faster CPU in the 6820 somehow loses its significance due to the average speed of its RAM.
All in all, the HP Compaq 6820s is a good investment, and I wholeheartedly recommend it to anyone who wants an affordable laptop for everyday home and office use.
I am proud owner of one.


After 6 months of usage, just as with any other laptop, the HP 6820 starts heating up more, CPU fan works all the time and if it's not on a flat surface it even freezes and turns of due to heat buildup. To deal with this problem you'll have to perform regular cleanup of the CPU heatsink-fan assembly. I've created an illustrated step-by-step guide that you can use to clean up your laptop. This is a recomended practice for any brand and model, at least once every 6 months.
