This chapter includes:

• Introduction

• Supported operating systems

• Configuring TCP/IP

• Configuring IPX frame types

• Setting Ethernet speed

• Restoring the network configuration

• Printing a network configuration page

Introduction

Once you have connected your printer to a network with an RJ-45 Ethernet cable, you can share the printer with other network users.

You need to set up the network protocols on the printer to use it as your network printer. Protocols can be set up by the following two methods:

Via network administration programs

You can configure your printer’s print server settings and manage the printer via the following programs that came with your printer:

• SyncThru™ Web Admin Service: A web-based printer management solution for network administrators. SyncThru™ Web Admin Service provides you with an efficient way of managing network devices and lets you remotely monitor and troubleshoot network printers from any site with corporate intranet access.

• SyncThru™ Web Service: A web server embedded to your network print server, which allows you to configure the network parameters necessary for the printer to connect to various network environments.

• SetIP: A utility program allowing you to select a network interface and manually configure the addresses for use with the TCP/IP protocol.

For further details, refer to the user’s guide on the network utilities CD that came with your printer.

Via the control panel

You can set up the following basic network parameters through the printer’s control panel:

• Configure TCP/IP

• Configure IPX frame types for NetWare

• Configure EtherTalk

This chapter will help you understand types of paper you can use with your printer and how to properly load paper in the different paper trays for the best print quality.

This chapter includes:

• Selecting print media

• Loading paper

• Selecting an output location

Selecting print media

You can print on a variety of print media, such as plain paper, envelopes, labels, and transparencies. Always use print media that meet the guidelines for use with your printer. Print media that does not meet the guidelines outlined in this user’s guide may cause the following problems:

• Poor print quality

• Increased paper jams

• Premature wear on the printer

Properties, such as weight, composition, grain, and moisture content, are important factors that affect the printer’s performance and the output quality. When you choose print media, consider the following:

• Desired outcome: The print media you choose should be appropriate for your project.

• Size: You can use any size media that fits easily within the paper adjusters of the paper tray.

• Weight: Your printer supports print media weights as follows:

- 16 to 28 lb bond (60 to 105 g/m

tray 3, tray 4

- 16 to 50 lb bond (60 to 190 g/m

- 20 to 24 lb (75 to 90 g/m

• Brightness: Some print media are whiter than others and produce sharper, more vibrant images.

• Surface smoothness: The smoothness of the print media affects how crisp the printing looks on the paper.

Guidelines for selecting and storing print media

Guidelines for special print media

When selecting or loading paper, envelopes, or other print media, keep these guidelines in mind:

• Always use print media that conform with the specifications listed on the next column.

• Attempting to print on damp, curled, wrinkled, or torn paper can cause paper jams and poor print quality.

• For the best print quality, use only high quality copier grade paper specifically recommended for use in laser printers.

• Avoid using the following media types:

- Paper with embossed lettering, perforations, or a texture that is too

smooth or too rough

- Erasable bond paper

- Multi-paged paper

- Synthetic paper and thermally reactive paper

- Carbonless paper and Tracing paper.

• Use of these types of paper could result in paper jams, chemical smells, and damage to your printer.

• Store print media in its ream wrapper until you are ready to use it. Place cartons on pallets or shelves, not on the floor. Do not place heavy objects on top of the paper, whether it is packaged or unpackaged. Keep it away from moisture or other conditions that can cause it to wrinkle or curl.

• Store unused print media at temperatures between 15

C and 30o C (59o F to 86o F). The relative humidity should be between 10% and 70%.

• Store unused print media in a moisture-proof wrap, such as a plastic container or bag, to prevent dust and moisture from contaminating your paper.

• Load special media types one sheet at a time through the multipurpose tray to avoid paper jams.

• To prevent print media, such as transparencies and label sheets, from sticking together, remove them as they print out.

Media type Guidelines

Envelopes • Successful printing on envelopes depends

upon the quality of the envelopes. When selecting envelopes, consider the following factors:

- Weight: The weight of the envelope paper should not exceed 90 g/m

(24 lb) or jamming

may occur.

- Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inches) curl, and should not contain air.

- Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.

- Temperature: You should use envelopes that are compatible with the heat and pressure of the printer during operation.

• Use only well-constructed envelopes with sharp and well creased folds.

• Do not use stamped envelopes.

• Do not use envelopes with clasps, snaps, windows, coated lining, self-adhesive seals, or other synthetic materials.

• Do not use damaged or poorly made envelopes.

• Be sure the seam at both ends of the envelope extends all the way to the corner of the envelope.

Acceptable

5.3 <

Unacceptable

• Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the printer’s fusing temperature of 195° C (383° F) for

0.1 second. The extra flaps and strips might cause wrinkling, creasing, or jams, and may even damage the fuser.

• For the best print quality, position margins no closer than 15 mm (0.6 inches) from the edges of the envelope.

• Avoid printing over the area where the envelope’s seams meet.

Loading print media>

Media type Guidelines

Transparencies • To avoid damaging the printer, use only

transparencies designed for use in laser printers.

• Transparencies used in the printer must be able to withstand 195° C (383° F), the printer’s fusing temperature.

• Place them on a flat surface after removing them from the printer.

• Do not leave them in the paper tray for long periods of time. Dust and dirt may accumulate on them, resulting in spotty printing.

• To avoid smudging caused by fingerprints, handle them carefully.

• To avoid fading, do not expose printed transparencies to prolonged sunlight.

• Ensure that transparencies are not wrinkled, curled, or have any torn edges.

Labels • To avoid damaging the printer, use only labels

designed for use in laser printers.

• When selecting labels, consider the following factors:

- Adhesives: The adhesive material should be

stable at 195° C (383° F), the printer’s fusing temperature.

- Arrangement: Only use labels with no

exposed backing between them. Labels can peel off sheets that have spaces between the labels, causing serious jams.

- Curl: Prior to printing, labels must lie flat with

no more than 13 mm (5 inches) of curl in any direction.

- Condition: Do not use labels with wrinkles,

bubbles, or other indications of separation.

• Make sure that there is no exposed adhesive material between labels. Exposed areas can cause labels to peel off during printing, which can cause paper jams. Exposed adhesive can also cause damage to printer components.

• Do not run a sheet of labels through the printer more than once. The adhesive backing is designed for only a single pass through the printer.

• Do not use labels that are separating from the backing sheet or are wrinkled, bubbled, or otherwise damaged.

Preprinted paper

• Letterhead must be printed with heat-resistant ink that will not melt, vaporize, or release hazardous emissions when subjected to the printer’s fusing temperature of 195° C (383° F) for 0.1 second.

• Letterhead ink must be non-flammable and should not adversely affect printer rollers.

• Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes during storage.

• Before you load preprinted paper, such as forms and letterhead, verify that the ink on the paper is dry. During the fusing process, wet ink can come off preprinted paper, reducing print quality.

Loading paper

Load the print media you use for the majority of your print jobs in the tray

1. The tray 1 can hold a maximum of 500 sheets of 75 g/m2 (20 lb) plain paper.

You can purchase optional trays and attach them below the standard tray to load an additional 500 sheets of paper for each tray. You can attach up to three additional trays. For order information for optional trays, see page 7.1.

Using the multi-purpose tray

The multi-purpose tray can hold special sizes and types of print media, such as transparencies, postcards, note cards, and envelopes. It is useful for single page printing on letterhead or colored paper.

To load paper in the multi-purpose tray:

1 Pull the multi-purpose tray down towards you and pull the multi-

purpose tray extension to hold longer paper.

• Envelopes: Flap side down and with the stamp area on the top left side.

Note

• To print on envelopes, you must open the rear cover and push the fuser levers upwards. The print quality will be enhanced.

2 If you are using paper, flex or fan the edge of the paper stack to

separate the pages before loading.

For transparencies, hold them by the edges and avoid touching the print side. Oils from your fingers can cause print quality problems.

3 Load the paper with the side to be printed on facing up.

• Transparencies: Print side up and the top with the adhesive strip entering the printer first.

• Labels: Print side up and the top short edge entering the printer first.

• Preprinted paper: Design side up and the top edge entering the printer first.

• Card stock: Print side up and the short edge entering the printer first.

• Previously printed paper: Previously printed side down and an uncurled edge entering the printer first.

Note

• Make sure that you have not loaded too much print media. The print media buckles if you load a stack that is too deep or if you push it in too far.

Caution

• When you print on special media like envelopes, labels, transparencies, or cards, the output location should be the rear cover. Open the rear cover to use it. See page 5.8.

Depending on the media type you are using, keep the following loading guidelines:

5.6 <

Loading print media>

4 Squeeze the multi-purpose tray paper width guides and adjust

them to the width of the paper. Do not force too much, or the paper will be bent, which will result in a paper jam or skew.

5 When you print a document, set the paper source and type in the

software application. See the Software Section.

For information about setting the paper source and type on the control panel, see page 2.4.

6 After printing, put the multi-purpose tray extension back to its place

and close the multi-purpose tray.

Tips on using the multi-purpose tray

• Load only one size of print media at a time in the multi-purpose tray.

• To prevent paper jams, do not add paper when there is still paper in the multi-purpose tray. This also applies to other tray.

• Print media should be loaded face up with the top edge going into the multi-purpose tray first and be placed in the center of the tray.

• Always load only the print media specified in page 5.2 to avoid paper jams and print quality problems.

• Flatten any curl on postcards, envelopes, and labels before loading them into the multi-purpose tray.

• When you print on 76 mm x 127 mm (3 x 5 inches) sized media on the multi-purpose tray, open the rear cover for straight paper path to avoid paper jams.

• When you print on transparencies, open the rear cover. If not they may tear while exiting the printer.

Using manual feed mode

You can manually load a sheet of print media in the multi-purpose tray if you select Manual Feed in the Source option from the Paper tab when you change print settings to print a document. See the Software Section. Manually loading paper can be helpful when you want to check the print quality after each page is printed.

This loading procedure is almost the same as the procedure for loading in the multi-purpose tray, except you load paper sheet-by-sheet in the tray, send print data to print the first page, and press OK on the control panel to print each following page.

1 Load the paper with the side to be printed on facing up.

2 Squeeze the multi-purpose tray paper width guides and adjust

them to the width of the paper. Do not force too much, or the paper will be bent, which will result in a paper jam or skew.

3 When you print a document, set the paper source to Manual Feed

and select the appropriate paper size and type in the software application. See the Software Section.

4 Print a document.

The display shows a message prompting you to load paper and press OK.

5 Press OK.

The printer picks up the print media and prints. After one page is printed, the message appears again.

Note

• If you do not press the button, after a pause the printer will automatically pick the print media.

6 Insert the next sheet into the multi-purpose tray and press OK.

Repeat this step for every page to be printed.

Selecting an output location

The printer has two output locations; the rear cover (face up) and the output tray (face down).

rear cover

output tray

The printer sends output to the output tray by default. To use the output tray, make sure that the rear cover is closed.

Printing to the output tray (Face down)

The output tray collects paper face down, in the order in which the sheets were printed. The tray should be used for most print jobs.

Printing to the rear cover (Face up)

Using the rear cover, paper comes out of the printer face up.

Printing from the multi-purpose tray to the rear cover provides a straight paper path. Using the rear cover might improve the output quality with special print media.

To use the rear cover, open it by pulling down and pull the rear cover extension.

Notes

• If paper coming out of the output tray has problems, such as excessive curl, try printing to the rear cover.

• To avoid paper jams, do not open or close the rear cover while the printer is printing.

Caution

• The fuser area inside the rear cover of your printer becomes very hot when in use. Take care when you access this area.

9 Troubleshooting

Clearing paper jams

This chapter provides helpful information for what to do if you encounter an error while using your printer.

This chapter includes:

• Clearing paper jams

• Troubleshooting checklist

• Understanding the status LED

• Understanding display messages

• Toner cartridge-related messages

• Solving general printing problems

• Solving print quality problems

• Common Windows problems

• Common Macintosh problems

• Common PostScript problems

• Common Linux problems

Note

• When removing paper that is jammed in the printer, if possible always pull the paper in the direction that it normally moves so as not to damage internal components. Always pull firmly and evenly; do not jerk the paper. If the paper tears, ensure that all fragments of paper are removed; otherwise a jam will occur again.

When a paper jam occurs, the Status LED lights red. Open and close the top cover. The jammed paper automatically exits the printer.

If the paper does not exit, check the display on the control panel. The message indicating the corresponding location of the paper jam appears. Refer to the table below to locate the paper jam and to clear it:

Tips for avoiding paper jams

By selecting the correct media types, most paper jams can be avoided. When a paper jam occurs, follow the steps outlined on page 9.1.

• Follow the procedures on page 5.5. Ensure that the adjustable guides are positioned correctly.

• Do not overload the tray. Ensure that the paper level is below the paper capacity mark on the inside wall of the tray.

• Do not remove paper from the tray while your printer is printing.

• Flex, fan, and straighten paper before loading.

• Do not use creased, damp, or highly curled paper.

• Do not mix paper types in a tray.

• Use only recommended print media. See page

• Ensure that the recommended print side of print media is facing down in the tray, or facing up in the multi-purpose tray.

5.1

Make sure that the Status LED on the control panel lights green and Ready is shown on the display.

Print a demo page to verify that the printer is feeding paper correctly. See page 2.8.

Check the demo page to see if it printed correctly.

Print a short document from a software application to verify that the computer and printer are connected and are communicating correctly.

If completing the checklist does not resolve the printer problem, check the following troubleshooting sections.

• If the Status LED is off, check the power cord connection. Check the power switch. Check the power source by plugging the power cord into another outlet.

• If the Status LED lights red, check the display message. See page 9.6.

• If a demo page does not print, check the paper supply in the tray.

• If the paper jams in the printer, see page

9.1.

• If an error message appears on the display, see page 9.6.

If there is a print quality problem, see page

9.11.

• If the page does not print, check the cable connection between the printer and the computer.

• Check the print queue or print spooler to see if the printer has been paused.

• Check the software application to ensure that you are using the proper printer driver and communication port. If the page is interrupted during printing, see page 9.9.

Background scatter

If marks repeatedly appear on the printed side of the page at even intervals:

• The toner cartridge may be damaged. If a repetitive mark occurs on the page, print a cleaning sheet several times to clean the cartridge; see page 8.3. After the printout, if you still have the same problems, install a new toner cartridge. See page 8.5.

• Parts of the printer may have toner on them. If the defects occur on the back of the page, the problem will likely correct itself after a few more pages.

• The fusing assembly may be damaged. Contact a service representative.

Background scatter results from bits of toner distributed on the printed page.

• The paper may be too damp. Try printing with a different batch of paper. Do not open packages of paper until necessary so that the paper does not absorb too much moisture.

• If background scatter occurs on an envelope, change the printing layout to avoid printing over areas that have overlapping seams on the reverse side. Printing on seams can cause problems.

• If background scatter covers the entire surface area of a printed page, adjust the print resolution through your software application or via the printer properties window.

Curl or wave • Ensure that the paper is loaded properly.

• Check the type and quality. Both high temperature and humidity can cause paper curl. See page 5.2.

• Turn over the stack of paper in the tray. Also try rotating the paper 180° in the tray.

• Try printing to the rear cover (face-up).

The PostScript driver may not be installed correctly.

The print job was too complex.

• Print a configuration page and verify that the PostScript version is available for printing.

• Install the PostScript driver; to installing the PS printer driver, see the Software Section.

• If problem consists, contact a service representative.

You might need to reduce the complexity of the page or install more memory.

Condition Possible cause Suggested solutions

Condition Suggested solutions

A PostScript error page prints.

The optional tray 2 (tray 3 or tray 4) is not selected in the driver.

When print a document in Macintosh with Acrobat Reader

6.0 or higher, colors print incorrectly.

Print job may not be PostScript.

The printer driver has not been configured to recognize the optional tray 2 (tray 3 or tray

4).

The resolution setting in the printer driver may not be matched with that in Acrobat Reader.

Make sure that the print job is a PostScript job. Check to see whether the software application expected a setup or PostScript header file to be sent to the printer.

Open the PostScript driver properties, select the Device Settings tab, and set the Tray2 (Tray3 or Tray4) option of the

Installable Options section to Installed.

Make sure that the resolution setting in your printer driver matches that in Acrobat Reader.

Common Linux problems

Please avoid changing print job parameters (via LPR GUI, for example) while a print job is

in progress. Known versions of CUPS server I encounter error “Unable to open mfp port device file!” when printing a document.

break the print job whenever print options are

changed and then try to restart the job from

the beginning. Since Unified Linux Driver

locks mfp port while printing, the abrupt

termination of the driver keeps the port locked

and therefore unavailable for subsequent print

jobs. If this situation occurred, please, try to

release the mfp port.

Common Macintosh problems

Condition Suggested solutions

The printer does not print a document from Acrobat Reader.

The document has printed, but the print job has not disappeared from the spooler in Mac OS 10.3.2.

Change the Print Method option to Print as Image when you print from Acrobat Reader.

Update your Mac OS to OS 10.3.3 or higher.

Condition Suggested solutions

• Check if the printer driver is installed in your system. Open Unified Driver Configurator and switch to the Printers tab in Printers configuration window to look at the list of available printers. Make sure that your machine is displayed on the list. If not, please, invoke Add new printer wizard to set

up your device.

• Check if the printer is started. Open Printers configuration and select your machine on the printers list. Look at the description in the Selected printer pane. If its status contains “(stopped)” string, please, press the OK button. After that normal operation of the printer should be restored. The "stopped" status might be activated when some problems in printing occurred.

The printer does not print a document from Illustrator on IPP printing.

10 Installing accessories

Precautions when installing accessories

Your printer is a full-featured laser printer that has been optimized to meet the majority of your printing needs. Recognizing that each user may have different requirements, however, Samsung makes several accessories available to enhance the printer’s capabilities.

This chapter includes:

• Precautions when installing accessories

• Installing a dual in-line memory module (DIMM)

• Installing a network interface card

• Using the hard disk

Disconnect the power cord:

Never remove the control board cover while the printer is plugged in.

To avoid the possibility of an electrical shock, always disconnect the power cord when installing or removing ANY internal or external accessories.

Discharge static electricity:

The control board and internal accessories (network interface card, DIMM, and hard disk) are sensitive to static electricity. Before installing or removing internal accessories, discharge static electricity from your body by touching something metal, such as the metal back plate on any device plugged into a grounded power source. If you walk round before finishing installation, discharge any static electricity once again.

Installing a dual in-line memory module (DIMM)

Your printer has a dual in-line memory module (DIMM) slot. Use this DIMM slot to install additional memory.

Your printer has 128 MB of memory which can be expanded to 512 MB. For information about ordering optional DIMMs, see page 7.1.

1 Turn the printer power off and unplug the power cord and printer

cable from the printer.

2 Remove the duplex-slot cover or the duplex unit from the back of

the printer.

Using Overlays

What is an Overlay?

An overlay is text and/or images stored in the computer hard disk drive (HDD) as a special file format that can be printed on any document. Overlays are often used to take the place of preprinted forms and letterhead paper. Rather than using preprinted letterhead, you can create an overlay containing the exact same information that is currently on your letterhead. To print a letter with your company’s letterhead, you do not need to load preprinted letterhead paper in the printer. You need only tell the printer to print the letterhead overlay on your document.

Creating a New Page Overlay

To use a page overlay, you must create a new page overlay containing your logo or image.

Create or open a document containing text or an image for use in a new page overlay. Position the items exactly as

you wish them to appear when printed as an overlay.

To save the document as an overlay, access printer properties. See “Printing a Document” on page 12.

In the Edit Overlay window, click
