Hewlett Packard release HP Officejet 6000 Wireless?



The Hewlett-Packard Company (NYSE: HPQ), commonly referred to as HP, is a technology corporation headquartered in Palo Alto, California, United States. HP is the largest technology company in the world and operates in nearly every country.

HP's Officejet 6000 Wireless is an inexpensive four-color ink-jet printer that, as its name implies, has wireless 802.11b/g connectivity. It also has an inexpensive price per print--as long as you buy HP's high capacity ink tanks. Though office ink-jets are nothing new, HP positions the Officejet 6000 as a greener and cheaper alternative to workplace color laser printers.

Setting up the printer isn't difficult but required a few more steps than with most ink-jet printers. The Officejet 6000 uses a print head that's separate from the ink cartridges, and you must open and install the print head before inserting the ink cartridges. You also have to attach the duplexing unit to the back of the printer.

The printer's design is simple and stylish, with rounded corners and a mix of light and dark gray plastic. There are four small buttons on the front, a Power button, a Print Cancel button, a Paper Feed button, and a Wi-Fi button allowing you turn off the wireless capabilities when not in use (a non-Wi-Fi version of the Officejet 6000 is available for US$30 less). The Officejet 6000 has a 250-sheet paper feed and a 50-sheet output tray. It can print automatically on both sides of a sheet of paper, which can help save both trees and money.

Your three options for connecting to the Officejet 6000 are Wi-Fi, USB 2.0 and Ethernet. The Wi-Fi setup was easy; in my experience, some printers make you struggle with the on-printer menus and keys to type in passwords, but the Officejet 6000 lacks such controls. You need to setup the wireless connection from your Mac during the driver installation from the bundled software CD. Once the printer was configured for our wireless network, it showed up automatically in Bonjour when installing the drivers on other systems.

Image quality

The Officejet 6000's print quality was impressive. During our jury evaluation, the text output received a Very Good rating and could truly be compared to laser quality. Many ink-jets struggle with printing clean text on plain paper; as the ink is absorbed into the paper, it can spread and look messy and fuzzy. Our jury found it difficult to notice any ink bleed or fuzziness with text.

Photos printed on HP's Advanced Glossy Photo Paper also received a Very Good rating. Colors were bright and pleasing, though the output wouldn't compare favorably to a high-end photo printer as it lost much detail in the darker areas of the print. It looks much better than a photo printed on a laser printer with glossy laser paper, however.

Photos and graphics on plain paper weren't of the same high quality, unfortunately, with colors appearing light and muted. Prints using HP's Colorlok Multipurpose paper looked better than prints made on our office copier paper, but there were still some banding in the color ramps of our test page and a blue cast to a grayscale photo we printed. The fine and curved lines looked great.

Cost

With printer reviews, we're constantly asked about the cost to run and maintain a device. If you buy HP's high capacity inks, the four cartridges will cost about $77, which, when divided by the company's estimated ink yields, breaks down to about $.03 per page (black only) and $.09 per page (color). That is a cheaper cost per color page than the last four sub-$1,000 color laser printers we reviewed, and the cost per monochrome page is pretty close to those laser costs.

If you opt for the lower priced, lower capacity inks, the cost per black page increases to $.05 (black) and a full color page will cost $.15. For comparison's sake, another office-oriented ink-jet, Epson's WorkForce 600 ( Macworld rated 4 out of 5 mice ), costs $.04 per page (black) and $.14 per full color page when using high capacity ink cartridges. Prints using HP's standard capacity ink cartridges cost just over $.07 per page (black) and over $.19 per full color page.

Speed

In terms of speed, the Officejet 6000 was an average performer. Over USB, its 15-second first page out time was fast. The Officejet 6000 printed a 10-page Word document in 1 minute, 15 seconds, and our 4-page PDF in 1 minute, 12 seconds. It took a while longer to print our 22MB color photo in Photoshop, clocking in at 2 minutes, 36 seconds.

Print times increased a bit when printing over our office wireless network. One thing I should mention is that the printer makes some interesting noises after each job, leading you to think, perhaps, that another sheet is about to exit the printer. It's not a big deal, but could be a little annoying if the printer is sitting on your desk next to you.

Macworld buying advice

If you're in the market for a lower-priced, more environmentally friendly printer for your small business, an ink-jet like HP's Officejet 6000 Wireless may be a better fit than a laser printer. Its smaller, uses less energy, has a low price per print and great looking text. The OfficeJet 6000 can also produce better-looking photos on glossy stock than laser printers typically can.

PRINTERS MAINTENANCE & CLEAN TIPS



In computing, a printer is a peripheral which produces a hard copy (permanent human-readable text and/or graphics) of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most newer printers, a USB cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces (typically wireless or Ethernet), and can serve as a hardcopy device for any user on the network. Individual printers are often designed to support both local and network connected users at the same time.

Printers require a little more maintenance than other peripheral devices. They have several different parts working together at once, which means it's easy for one or more of the parts to jam and cause performance problems. Cleaning your printer regularly will help prevent these complications.

Every printer is different of course, so the cleaning and maintenance process may vary just a bit. But for the most part, there are a few steps you can take that will help prolong the life of your machine-regardless of the type of printer you have.

Preventative Care of Your Printer

It's a good idea to perform preventative maintenance on your printer as often as you can. One of the most important parts of your device that you must always keep clean is the print head. If a printer has not been used for quite some time, there's a greater chance of the print head becoming clogged with dried-up ink. Needless to say, this will have a significant impact on the quality of output, and it can even do permanent damage to the printer. You can easily avoid any blocking or obstruction by simply cleaning the print head on a regular basis. The best way to do this is with a dry cloth. Gently wipe down every possible surface you can reach-especially all the nooks and crannies on the inside of the printer. Tiny particles of dust and dirt have a tendency to find their way into every little crevice, so be as thorough as you can.

Nowadays, most printers come with an automatic utility program that can instruct the printer to do a self-cleaning process. If you run these cleaning cycles fairly often and wipe down the inside of your printer on a regular basis, you shouldn't encounter too many problems. On the other hand, printers that do not come with an automatic cleaning cycle require a bit more attention. In this case, you may want to consider purchasing a cleaning kit, which usually includes a tube of ammonia that you can lightly spray on the print head to get rid of crusted ink.

Manually Cleaning Your Printer

If you are experiencing printer jams or any sort of ink build up, you can clean the print head manually by performing the following steps:

1.) Remove the cartridge from the printer. Dip a cotton swab in rubbing alcohol or hot water, and gently wipe down the cartridge. This should soften up the dry, crusted ink.
2.) Then, soak the print head in hot water and leave it there over night.
3.) If the print head is still clogged after soaking it all night in water, let it soak in rubbing alcohol over night.
4.) After removing it from the water (or alcohol), wipe off the print head with a damp paper towel, and let it dry off carefully.
5.) When you put it back in the printer, try running the self-cleaning cycle again.

If your print head is still clogged, you can either buy a new cartridge or you can contact a service technician who can try to repair the damage.

SOLVING REPEATED PAPER JAMS

1. Check to see that paper is correctly loaded in the trays, and that all width guides are correctly set (not skewed).

2. Ensure that the paper tray is set for the size of paper installed and that the tray is not overloaded with paper.

3. Try turning over the stack of paper in the tray. If you are using letterhead paper, try printing from Tray 1.

4. Do not use previously printed paper or torn, worn, or irregular paper

5. Check the paper specifications. (If paper is outside of the recommended specifications, problems may occur.)

6. When duplexing, the printer rolls paper under Tray 3 and causes a jam. Pull Tray 3 out of the printer completely and remove any paper from under the tray. Insert Tray 3 back into the printer.

7. Printer may be dirty. Clean the inside of the printer with a dry, lint-free cloth.

8. Check that the correct paper size is installed.

9. Check that all damaged or jammed paper is removed by pulling it out of the printer.
