Panasonic KX-FLB802CX : A super – value copier

Panasonic KX-FLB802CXThe Panasonic KX-FLB80CX is in a class of its own: it is the only copier- based MFD we tested. Being copier- based, it comes with separate drum and toner cartridges. The advantage of such a device over printer based MFDs is this: the toner and drum have different duty cycles, and the drum’s duty cycle is always more then twice that of the toner. In the case of printer based laser MFDs, the toner and drum are integrated, and the duty cycle of the single unit is that of the toner- so you have to replace the whole thing even when the drum’s duty cycle hasn’t been expended. With copier- based laser MFDs, you need to change either the toner or drum as and when its duty cycle is over. This proves to be cost-effective. However, copier based units have traditionally been more expensive to manufacture. This one breaks the mould, and costs just Rs $400.
At 44 x 44.5 cm, this MFD occupies a comparatively large area, but can just about fit beside a PC on a regular desktop. Installing the drum is very easy, but installing the cartridge is not. Input tray capacity is 250 sheets, and there is also a multipurpose tray for additional paper storage.
The printer supports 600 x 600 dpi. The initialization time of this MFD is just under 20 seconds. For the text document, it took 14.7 seconds to print the first copy and thereafter printed at16 ppm. It takes a couple of seconds longer to print the first copy of the combi-document, but thereafter prints at just about the same speed as the text print. Text is quite sharp, and inverse text was pretty good, too.
The scanner supports 600 x 1200 dpi, but the driver doesn’t support the newer WIA interface – which many modern scanners do, because it is more standardized. The scanner is good at capturing colors and fine details, but is extremely slow, especially at resolution lower then 600 dpi. Since these are the resolutions at which people most often scan documents and even photographs, the scanner loses out on performance points. It took 27.2 seconds to scan a monochrome document at 200 dpi, while a color document at 600 dpi took just over 2 minutes – pretty good. The scanner did not fare well in the OCR test, committing 25 mistakes, which is bad.
The first copy took 18.3 seconds. We found the copies rather dark, and as a result, the inverse text was not very legible. Fine print didn’t turn out legible, either.
This is the only contender that comes with a handset, which doubles up as a phone if you are using your phone line for fax (as is the case with most SoHo users. It can store up to 170 pages of incoming fax in case it runs out of toner. The hardware junk fax prohibiter filters out faxes faxes from unwanted numbers, using caller ID.
The interface is USB; thought there is the option to upgrade to an Ethernet port interface. The MFD comes with Readiris 7 OCR, Remote Control PCFAX to send fax via the PC, and a network Scan Module, which helps deploy the machine over a network. The duty cycle of the printer is 10,000, which is the same as that of its drum, while the toner cartridge has a duty cycle of 2,500. cost per page comes out to be Rs 1.20- a bit on the higher side for a laser MFD. Stile, like we said, it’s cheap for a copier-based MFD.

Social Networking Site : Some cautions should be taken

A few days ago I got an invitation to join a new social networking site from a co-worker. (Social networking sites like MySpace, Facebook, and Windows Live Spaces are services people can use to connect with others to share information like photos, videos, and personal messages.)

At first I thought it was strange that she was inviting me to join since we work together and already communicate several times a day using both high-tech and low-tech methods.

Even though I thought the invitation might have been a fraudulent e-mail message, I sent it back to her and told her I would join, if she was sure the invitation wasn’t a scam.

A few minutes later I received an e-mail message from my co-worker saying that she was horrified to learn that the social networking site had e-mailed an invitation to all of her contacts without her knowledge.

When you first sign up, many popular social networking sites offer to scan your e-mail address book to find out if other people you know are on that particular social network. Then you can choose whether you want to connect with others who are already on the network or send invitations to people who aren’t. These sites should ask your permission to send out invitations. My co-worker claims that this particular site did not ask her permission.

You’ve probably heard the news reports about how much time teenagers spend on social networking Web sites. However, online social networking is now used by adults as well as kids. Adults use these sites to keep in contact with friends or even to help them get new jobs. Whether you’re the parent of a child who uses a social networking site or if you use these sites yourself, here are a few basic guidelines to follow.

Social networking safety tips

Educate yourself about the site before you post any personal information. Evaluate the social networking Web site and read the privacy policy and code of conduct carefully. To avoid giving the site the e-mail addresses of your friends, do not allow the site to scan your e-mail address book.

Assume what you write on a social networking site is permanent. Even if you have the ability to delete your account, anyone on the Internet can easily print out the information or save it to a computer.

Consider using a site that doesn’t post your information publicly. Some sites allow anyone to view the content you post on the site; others only allow members to view pages. If you want to help protect your information even further, use a site that allows you to password-protect your information and only give your friends the password.

New Hybrid Hard Drives From Samsung and Seagate

When they were introduced a couple of years ago, hybrid hard drives seemed enticing. Pairing a standard hard drive with a flash component sounded like a good way to deliver on the theoretical performance boosts that flash can offer while still providing the long-standing price, capacity, and performance benefits of hard disks. We’ve now tested the first two hybrid hard drives to reach market, and we’ve discovered some clear benefits–but other results were inconclusive.

We looked at Seagate’s Momentus 5400 PSD drive, announced today, and Samsung’s SpinPoint MH80 drive, released this summer. Both models are 2.5-inch, 160GB notebook drives with 256MB of nonvolatile flash memory cache on board. The hard-drive industry concentrated on introducing the new technology in laptop drives because notebooks would be more likely to reap the benefits that hybrid tech promises, including faster boot time and power savings.

In the Test Center
Our Test Center examined the $190 Seagate Momentus 5400 PSD and the $299 Samsung SpinPoint MH80 alongside a $250 non-hybrid Hitachi Travelstar 7K200 (HTS722020k9SA00). We tested all three drives on a Dell Inspiron 1520, running a Core 2 Duo T7300 2-GHz CPU and 2GB of memory. Click the icon below to see a chart of our test results. To test the hybrid drives, we did a fresh installation of the 32-bit version of Microsoft Windows Vista Ultimate and updated the drivers and BIOS. Surprisingly, we had to wait about 20 minutes for the operating system to recognize each hybrid drive. Once each drive was recognized, however, an NVCACHE tab appeared in the driver properties, and the drive was ready to work with Vista’s ReadyDrive technology, which uses the drive’s flash cache. You must run Windows Vista to use a hybrid hard drive.

To prepare the system to take advantage of any power savings the hybrid drive would provide, we entered the Power Options control panel and, under the Balanced power profile, changed the settings to enable the Windows Hybrid Hard Disk Power Savings Mode. Our experience was, in fact, much like that of someone who was upgrading their existing notebook with Vista and a hybrid hard drive.

The minimum requirements for using a hybrid drive are tied in with Vista’s minimum requirements: Beyond having a system that runs Windows Vista and uses a Serial ATA interface, Seagate suggests that your PC have 2GB of memory, a dual-core or quad-core CPU, the latest BIOS revision (less than one year old), and the newest drivers. Seagate notes that hardware drivers can have an impact on a hybrid’s benefits, though the company doesn’t go into detail on this point in its reviewer’s guide; when asked, the company stated that slow drivers can affect a PC’s boot performance.

Power Savings Confirmed
The Hitachi drive is a performance model that spins at 7200 rpm, in contrast to the 5400-rpm speed of the Samsung and Seagate drives. However, the Hitachi model is representative of the direction notebook computing is going, as increasingly we’re seeing mainstream and power notebooks with a 7200-rpm drive inside.

As such, it was no surprise that the Hitachi drive was the fastest at our timed hard-drive write tests. The Hitachi model required 154 seconds to copy 3.06GB of files and folders, versus the Seagate’s 208 seconds and the Samsung’s 217 seconds.

On our read tests, the difference was much smaller. The Hitachi required 25 seconds to search through its files, while the Seagate needed 29 seconds and the Samsung took 30 seconds. On our Panda virus-scan test of 6.12GB of files, the Hitachi and Seagate tied at 34 seconds, and the Samsung was just a shade behind at 36 seconds. Whether we can attribute those tight results to the hybrid models’ use of 256MB of nonvolatile cache is uncertain, but the flash memory could be a factor.
