6.1 Precautions when replacing parts
6.1.1 Precautions when assembling and disassembling
* Use only approved Samsung spare parts. Ensure that part number, product name, any voltage, current or temperature rating are correct. Failure to do so could result in damage to the machine, circuit overload, fire or electric shock. * Do not make any unauthorized changes or additions to the printer, these could cause the printer to malfunction and create electric shock or fire hazards. * Take care when dismantling the unit to note where each screw goes. There are 19 different screws. Use of the wrong screw could lead to system failure, short circuit or electric shock. * Do not disassemble the LSU unit. Once it is disassembled dust is admitted to the mirror chamber and will seriously degrade print quality. There are no serviceable parts inside. * Regularly check the condition of the power cord, plug and socket. Bad contacts could lead to overheating and firfe. Damaged cables could lead to electric shock or unit malfunction.
6.1.2 Preautions when handling PBA
Static electricity can damage a PBA, always used approved anti-static precautions when handling or storing a PBA. >> Precautions when moving and storing PBA
1. Please keep PBA in a conductive case, anti-static bag, or wrapped in aluminum foil. 2. Do not store a PBA where it is exposed to direct sunlight.
>> Precautions when replacing PBA
1. Disconnect power connectors first, before disconnecting other cables 2. Do not touch any soldered connections, connector terminals or other electronic parts when handling insulated parts.
>> Precautions when checking PBA
1. Before touching a PBA, please touch other grounded areas of the chassis to discharge any static electrical charge on the body. 2. Take care not to touch the PBA with your bare hands or metal objects as you could create a short circuit or get an electric shock. Take extra care when handling PBAs with moving parts fitted such as sensors, motors or lamps as they may get hot. 3. Take care when fitting, or removing, screws. Look out for hidden screws. Always ensure that the correct screw is used and always ensure that when toothed washers are removed they are refitted in their original positions.
6.1.3 Releasing Plastic Latches
Many of the parts are held in place with plastic latches. The latches break easily; release them carefully. To remove such parts, press the hook end of the latch away from the part to which it is latched.

Samsung CLP-510/550 Series
Color Laser Printer Product Guide
World-renowned quality and innovation delivering unprecedented productivity and solutions.
Productivity. Quality. Solutions. Samsung works for you.
Samsung CLP-510/550 Series color laser printers are the best in the business because theyre the most complete. Theyre fast. Powerful. Durable. Efficient. Delivering sharp laser text and beautiful photographquality images, even on plain paper, in a way that makes your documents more powerful than ever.

Check the specs.

Compare our CLP Series color laser printers to the competition, and its easy to see ours are the fastest and quietest. What you wont find in their brochures, though, is the CLP Series cost of ownership advantage. As soon as we introduced our CLP Series printers, the CLP-500 was independently tested to be the most cost-effective among key competitors, delivering the lowest cost per page and lowest total cost of ownership when printing both color and black and white.

Superior Productivity

Samsung color laser printers are the most productive in the category. With fast print speeds. High paper capacity. The easiest toner changes. And so much more, including the largest toner capacity in their class and a low cost per page.
Save big when printing both color and black and white.

Higher Quality
In a recent reliability survey, Samsung was the only color printer manufacturer rated Outstanding by PC World magazine (12/03). Our printers are also constantly recognized for their superior print quality, technical innovation and more.
Compared to the Samsung CLP Series printer, the cost of printing one color and one black and white page is almost 8% higher for the Minolta 2300W and a staggering 86% higher for the HP 1500L.
Save almost $160 on every box of paper printed.

Better Solutions

Always leading with technology, Samsung color laser printers are the first with built-in automatic duplexing. They also offer network and wireless solutions. Professional-level color matching software. And the support of a solutions team dedicated to meeting unique customer needs.
With its significantly lower cost per page, a Samsung CLP Series color laser printer can save you up to $15.75 in printing costs each ream. Thats almost $160 per 10-ream box.
Test Methodology Summary NSTL, Inc. conducted an independent cost per page analysis that included three high-quality color laser printer models. The cost per page analysis is a comparison of the indices that could be used to forecast possible printing costs after the purchase of the printers. Each printers index is arrived at by summing the individual consumables cost per page. The individual consumable cost per page is calculated by dividing the accumulated consumable yield from all test runs into the total cost of the consumables utilized by those runs. Toner yield output is defined as the total of all printed sheets, for six cartridges of each color (including black), that did not contain a major permanent print error (e.g. print quality deemed unacceptable). Drum yield output is defined as the total number of sheets printed, regardless of print quality, while printing with a specific drum. NSTL concluded that the Samsung CLP-500 offered the lowest cost per page and the lowest total cost of ownership, and that the difference in the cost per page could save the end user a significant amount of money over the life of the printer. All figures noted are from NSTLs independent test.
Toner changes as easy as 1-2-3.
Instead of the 16 time-consuming steps required by other color laser printers to change all four cartridges, our NO NOIS technology makes it easy to change them all in just three quick steps.
Samsung CLP-510/550 Series Toner Change
Easier. More reliable. Our innovative engine design is a breakthrough.

Our CLP-510/550 Series color laser printers feature an innovative new static engine architecture that requires fewer moving parts. With this exclusive NO NOIS (Non-Orbiting Noiseless Optic Imaging System) technology, youll enjoy easier toner changes, higher reliability and quieter operation.

3 Steps

Open Exchange Close
Its a simple 3-step process. Open a door. Exchange a single cartridge or all four. Close a door. No headaches. No fuss. No messy toner spilling all over your favorite khakis.
Samsung CLP-510/550 Series Printers
With our exclusive NO NOIS engine design, the toner cartridges are fixed securely in place, resulting in easier, quieter, more reliable operation.

Fixed Toner Cartridges

Photo-quality printing on plain paper.
Samsung CLP-510/550 Series printers deliver photoquality images without the expense of specialty paper. So the beautiful image you see on screen is the beautiful image that shows up in your documents.

Competitors Printers

The competitors print process requires constant rotation of all toner cartridges, resulting in more difficult toner changes, excessive noise and lower reliability.
Rotating Toner Cartridges
Lowest noise level in the category.
One of the benefits of NO NOIS technology is that it allows our CLP-510/550 Series color laser printers to operate as low as 48 dBA, making for a more comfortable workplace.
Built-in duplex unit takes the guesswork out.
Manual duplexing, or printing both sides of a sheet of paper, is often an aggravating scenario of endless guesswork trying to figure out exactly how to feed the paper. Its a huge waste of time and paper and toner that we thought youd be better off without. Thats why we designed the CLP-510/550 Series with built-in duplexing. The whole process is as simple as pushing a button. On the competitors machines, automatic duplexing is about $399 extra, or not even an option.
Increased productivity. Higher quality. And more.

The speed you need.

Our CLP-510/550 Series printers deliver documents fast. They print in color up to 6 pages per minute, black and white up to 25 pages per minute.

Plays well with others.

With Ethernet and 802.11b wireless options, plus the embedded USB 2.0 (and IEEE-1284 parallel ports on 550 Series), CLP-510/550 Series printers are ready for easy plug-and-print setup on almost any system.
Included cassette provides superior paper handling.
Our CLP-510/550 Series printers have one of the highest paper capacities in the category. Theyre also one of the only ones that include a standard paper cassette, for sleeker, more secure paper storage. You can print 350 pages without ever having to reload.

Unprecedented reliability.
Because they operate with fewer moving parts, our CLP-510/550 Series color laser printers operate with fewer service interruptions.

Unprecedented warranty.

The CLP-510 comes with a 1 year on-site warranty, the only warranty like it in its class. When you offer a reliable printer, you can do things like that.

Maximum Paper Capacity

Big jobs are no problem.
With the USB 2.0 connection and built-in high-capacity expandable memory, even the heaviest load is handled with ease.

Low running costs.
