      Advantages

      Disadvantages

      Slim + Trustworthy (just like me)

      The CanoScan N670 is a low profile A4 document scanner.

      As a product which has been around for quite a while now, it's readily available secondhand for under £20.

      Firstly the bad points - Unfortunately this product is only compatible with USB 1 - which means it can be slightly slower in operation than its newer competitors. The maximum optical resolution is 600 x 1200 dpi, with a 9600 x 9600 dpi interpolated output.

      Another downside is the lack of a negative or slide scan compartment - again a feature which most newer models posses.

      On the plus side, the lid is cleverly designed so it opens with the hinge working in an unconventional way. This allows the user to scan awkward or bulky documents with ease.

      The scanner is compatible with both Macs and PC's, although if you're buying this product second hand, you may have to download the software drivers needed for it to work effectively. The Canon support website has them readily available.

      The scanning process takes place at a fairly average speed. It isn't slow, but it's by no means the quickest product available. The preview takes around 14 seconds to complete, and the final scan depends on the resolution you've chosen to work at.

      The actual unit itself measures 25.6 cm x 38.3 cm x 3.4 cm, which means it's very thin from top to bottom. The design is quite stylish and modern looking, even though it's now a good few years old.

      Quality of results are very good - certainly on a par with the other mid range scanners i've used.

      I've had this product for five years, and it's been both reliable and efficient. If you see one of these online for 10 or 20 quid, I recommend giving it a go, as it won't let you down.

      I also own the Cannon N670U and like some was also slightly disappointed, but after downloading the latest drivers and software the scanner came to life with vivid colours and sharp images plus a huge Increase in Speed. The original review of this scanner was very good which was why I brought it, I just wonder what drivers and software was used in the tests. Anyway I now have a great product and like any other hardware I own now check on their website's for driver/software upgrades as In this case It made a huge difference.

        • "Can stand it
        • saving space"

        The Canon CanoScan N670/676U is a mid range USB flat-bed A4 scanner. It has been around for nearly 2 years and has just left Canon?s current range. The scanner retails for about £50 but in March 2002, I purchased a refurbished on for £45 (from Special reserve url: ukgames.com, though I bought it from a shop and not the website). ?Basic specs: This is a mid range USB 1.1 (not the superior USB 2.0) CIS scanner capable of scanning at 600x1200 dpi (dots per inch) featuring 48bit input and 24 bit output. It's compatible with all windows versions (including Win XP if you use the Win 2000 drivers) and MAC it requires a USB port; that also supplies it with power, basically if your PC has a USB port, it's good enough to handle this. Also 10 (min) - 200 (max megs of hard drive are required to install the scanner. The cable is about 1 meter long, which is acceptable. The reason I bought this scanner was first of all because of its price relative to its quality. Secondly this scanner looks very sleek and attractive, it's one of those slim ones, and it comes with a stand so it can rest vertically while scanning. It also has a "Z-lid" which on paper is very innovative as that means when scanning thicker items the cover wraps itself over the object to be scanned and you don't put excessive pressure onto the cover. In practice, it's pretty useless (and far from unique). It also features some useless quickscan buttons on the front, which I doubt many people use as you are unlikely to get what you want (but nevertheless good for the novice). These allow you to scan the image, to email it, or to print it. You need to have the supplied software to make use of this. Also there is no 35mm negative/positive scanner as you would find with other scanners. However this scanner can scan multiple photographs in one scan. The package comes with Arcsoft PhotoStudio 2000 (Editor), Arcsoft Photobase (Album programme), ScanS
        oft Omnipage Pro (Text recognition software), and Adobe Acrobat Reader. Which is a very average line up (none of which I installed; except Omnipage, which I have only used once, and isn't any good if the text is small, plus I have the full version of Acrobat anyway). ?Installation The manual (which is also for the N1240U; the old top of the range Canon home scanner, and the 676U which is the same scanner but a different colour) is pretty good, it guides you through the installation process step by step, and I had no trouble with it. Also you find the one year warranty, which is pretty standard (even with the "approved" refurbished one I got). ?Operation The most important thing I think is a scanner that does what you wish to do, and efficiently without stressing your PC too much, and by in large, the N670U achieves it. The interface (i.e. what you see after you click scan on whatever programme you use) is pretty standard. First of all you choose the media you are scanning, you can choose from B/W, Grayscale, Colour Documents, Colour Photos or Text Enhanced. That's a pretty small choice compared with say the Epson one which has about a dozen, but never mind that. (Obviously options are saved after you leave the programme). The first thing you do is click preview, this starts a preview scan which takes about 15 seconds (and maybe a calibration which takes a minute), you choose the resolution of the resulting image, from 75 to 2400 dpi and then play around with some more advanced settings if you wish to (like clearing bits of dust etc). Then you choose the section you wish to scan, the scanner can do that automatically if you wish, just click the align button as many times as required. With this scanner, you can also put more than one item into the bed, and it will automatically align them and scan for you, pretty clever. Scanning a full colour A4 page takes about one and a half
        minu te, either way, longer than an Epson scanner. During scanning you can use other programmes (well you'd expect that with a Pentium 3 with 320 megs of RAM right?), but it takes a few goes to see the progress, the interface is fiddly! Overall the operation feels second class, especially compared to an Epson scanner, but on the flipside, it's miles better than the Afga scanner I used a while back. I'd love to know how good USB2.0 scanners are though... Another thing that annoys me a little is the noise generated by the scanner during its operation, instead of an efficient buzz, it sounds like a painful push, something you just don't want a machine so beautifully delicate to go through. The product is pretty solid but because of its size, there's just the unjustified feeling of fragility. ?Scan quality I believe that all scanners can scan images of the same quality. To be honest, you will rarely scan images at over 300dpi, and if you ask the scanner to scan reasonable size items at over 700 dpi (sometimes 600 dpi) it says that the object is too large to scan at that resolution, so something to bear in mind if you are solely purchasing a scanner to scan large items at high resolutions. It has Canon's LIDE technology for superior scanning, but who cares???? ?Conclusions That's about all you need to know really. Overall for £45 this is as good a scanner as you can get. This is not the best scanner in the 600x1200 dpi range, but you can do a lot worse, and looks do matter at the end of the day. The scanner is very good, but it's let down by the fact that it can be better in many departments, it would be better if it could scan a little faster and also the interface just lacks a few options here and there and is a little fiddly. However I would not pay the retail price of £50 for this, I would simply take a risk on another brand (Packard Bell do a similar looking/spec one
        for £40 re tail) or just spend a little more to get an Epson one. My scanner is an official refurbished one, and there are lots of these about, this is worrying for consumers who may wish to purchase a brand new one, now I don't know if this is common, but it's certainly worrying. For more info visit the Canon website Recommended alternatives: One of the latest CanoScan scanners with USB2 (if your PC has USB 2) or one from the Epson Perfection Range which is superior.

          Advantages

          Disadvantages

          I recently bought the Canon N670U after doing some research both on the internet and around the shops. My previous scanner had been an Epson which ran through the parallel port. Having moved to using NT4 then win200o and finally XP pro ,non of these operating systems supported my old scanner so i was forced to upgrade. I wasnt keen on paying lots of money for something i didnt plan on using a lot and had almost given up on finding a suitable product when my eyes settled upon the Canon during a last hope visit to my local PC world store. Its sleek lines and style were the first thing that attracted me ,then the price . But could should a cheap scanner deliver the goods ? . I had my doubts but then Canon are well respected for their imaging technology so out came my wallet and the deal was done. The Canon is simplicity itself to install. Just connect the USB cable ,turn on, load the CD,job done. There is a conprehensive booklet but it is almost un-necessary as it is so simple and intuitive to use. Any worries about quality were quickly dispelled. The scan quality is excellent,much better then my more expensive previous scanner. Added bonus;s are the sleek styling,lightness and portability ,included software which included photosuite and omnipage and the fact that it doesnt require a power supply ,being powered from the USB port. These means it could easily be carted around with a lap top should you need to. To summarise then,a top quality product at a bargain price. You don;t need to spend any more for a scanner unless you want something really specialised.

            Disadvantages

            Most people will recognise the Cannon brand and will associate it with photography and with good reason, as they produce very good cameras. Over the past few years Cannon has also got into producing other imaging products such as Digital Cameras, Printers and Scanners. All of these products I would say are among the best in the world. This review is going to be about one of their latest scanners, the model name is N670U. This wont mean much to anyone, well except probably those who work for Cannon... or possibly those people who sell Cannon products... but any way it's just another number to the average person! Hopefully this review of the Cannon N670U Scanner will not be too boring or techy... ** Software/Installation ** Well as you would expect with most computer peripherals these days it is extremely easy to install! The scanner itself connects to the computer via a USB port (this is the only way, there is no parallel connection). This is good because it means that the power for the device is provided via the USB connection, so there are less cables trailing about your desk, yay! Well that just about covers the hardware side of the installation! Now onto the software side, which is just as easy... With your computer on, you have just plugged the USB lead from the scanner into the computer. The device will be automatically detected as a plug a play device and you will be prompted for the drivers for the scanner. Insert the CD provided with the scanner and then select the directory that the drivers for your operating system. All you have to do then is to go through the installation process; there are no major decisions to be made, so all you really have to do is click next! Wow, the scanner is now installed, this should have taken no time at all, well at least it was very quick for me! ** What the Scanner Looks Like ** He he he... this scanner is a treat, like most devices over the last few years such as modems an
            d printers scanner have also been getting make overs to make them look better. This scanner is no exception, it is small and sleek looking and also very thin, in fact it is about 3 cm in height! This scanner also has another neat feature that you can add to it, it has a stand so that you can stand it on its side, while still scanning. This, surprisingly works very well, the only thing you have to do is clip the stand to the scanner, very easy, and attach a bit of Velcro to the scanner and its lid, to keep the lid shut! The scanner also has a very nice blue and grey coloured theme, which is better than the standard colour scheme for computer items! ** Operation ** There are two ways in which this scanner can be used; one way is to use one of the three buttons on the front of the scanner. These buttons are the "Scan" buttons, which performs a scan and outputs the image into the ArcSoft Photobase program (provided with the scanner), the next button is the "Copy" buttons, this scans the image and then outputs the image direct to the printer and the final button is the "Email" button, this buttons will scan the image and insert it into an email as an attachment. The other way of using the scanner is through the TWAIN system. What TWAIN does is provide a standard interface between a scanner and the application that it is going to be output to. This means that the scanner that you have just installed will work with just about every drawing package out on the market at the moment. This is a very simple system to use, first you have to select the TWAIN source, basically select your scanner, and then select acquire image. This will load the scanning interface from which you can preview the image in the scanner, select the area to scan, select the document type and the quality of the scan that you are going to perform. This is all very easy to use and once you are ready to scan the program will take you back to what
            ever drawing package you were using and you will have your image ready for editing. ** Scan Quality/Speed ** Although the specification, see below, says that this is quite a fast scanner you don't always want to believe what the manufacturers say about it. I have been using this scanner for quite a while now and I would say that it is a very fast scanner. Of course some things are going to take longer like high quality scans of photographs, but overall this is a very fast scanner. Along with the speed, the scanner also gives you a very good quality image, okay the image depth might not be the best that you can get, but for me this is just fine. Any more I feel would be overkill and I would probably never need that sort of quality any way! ** Specification ** • Scanner Type: Flatbed • Scanner Element: CIS (Contact Image Sensor) • Light Source: 3-colour (RGB) LED • Optical Resolution: 600 x 1200 dpi • Scanning Bit Depth: Colour - 16 bit input/8 bit output for each colour (RGB) • Scanning Bit Depth: Greyscale - 16 bit input/8 bit output • Scanning Speed: Colour - 16 msec/line (600 dpi) • Scanning Speed: Greyscale - 5.3 msec/line • Scanning Speed: B&W - 5.3 msec/line (600 dpi) • Preview Speed: 15 sec (approx) ** System Requirements - Windows ** • Operating System - Windows 98, Windows 2000 Professional, Windows Millennium Edition, Windows XP Professional and Windows XP Home Edition • Computer - IBM PC/AT Compatible, USB Port • CPU - Pentium 150 MHz or higher • RAM - 64 MB or more • Display - High Colour (16 bit) and 800 x 600 or more pixels ** System Requirements - Macintosh ** • MacOS 8.6 - OX X (Classic mode only) • Computer - Macintosh with USB Port • RAM 64 MB or more • Display - 32,000 or more colours ** My Thoughts ** This is a very go
            od scanner and at £70 I thought was very good value for money. It is easy to install and use, I would say once you have unpacked it you should be using within ten minutes. All credit to the people at Cannon for creating a very easy to use, high quality scanner. This is defiantly worth the money, if you are looking for a good scanner for the home, then this I feel has to be IT!

              • "visible scan lines"

              Three weeks ago I bought a Canon CanoScan N650U. I was very pleased with the scan quality, speed and software bundle that came with the scanner. The N650U is a great bargain - a perfect scanner for all around applications capable of resolving fine details and colors. One week ago I read about the newest Canon scanner line including N670U and N1240U. On paper the N670U seemed like better performer than my N650. N670U manages 48 bit processing for finer color resolution, it has newer drivers it has new design, looks sturdier (and feels, by the way)and so on. Since I still had a 30 days return back guarrantee I decided to return my N650U and try a N670U instead. And so I did. Instalation of the scanner was painless. Software bundle that came with the scanner is practically the same as that of N650U. The scan software interface looks and feels almost the same as that of N650U. There are some new settings like QARE scanning (Quality Automatic Retouching Engine) if you want to use automatic retouching of dust particles off your scans. The scanner feels a bit heavier than N650 but in my opinion the old scanner is much cuter. And to the scan quality. After scanning my first photo I was shocked. Picture was darker and details in the shadow have disappeared compared to a scan I took with N650U. There were blots of colors in shadows - (are those artifacts?).Colors felt stronger then with N650 but - were those the right colors?? No. Turquoise was not turquoise anymore - it was blue, orange is red!!! Another phenomenon that clearly appeared was noise in image's dark areas. I could see scan lines. It is very ugly I think. The image was overexposed in brighter areas compared with N650U. It felt like the details in these brighter areas were also gone. Well what more can I say. While this scanner feels more solid than N650U it has far inferior scan quality. N650U is a real bargain - N670U IS NOT. So I went to the shop and took my old scanner back. Tha
              t was the only right thing to do.
