Printing Tips for successful printing Storing paper Use the following guidelines to avoid paper feeding problems and uneven print quality. • Store paper in an environment where the temperature is approximately 21°C (70°F) and the relative humidity is 40%. • Store cartons of paper on a pallet or shelf rather than directly on the floor. • If you store individual packages of paper out of the original carton, make sure they rest on a flat surface so the edges do not buckle or curl.
Printing Avoiding jams You can avoid most paper jams by correctly loading paper and specialty media in the printer. See the following for loading instructions: • Loading 500-sheet trays • Loading the 2000-sheet tray • Loading the multipurpose feeder The following hints can help you avoid paper jams: • Use only recommended paper. Refer to the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.
3 Media specifications Media is paper, card stock, transparencies, labels, and envelopes. The last four are sometimes referred to as specialty media. The printer provides high quality printing on a variety of media. A number of things must be considered concerning media before printing. This chapter provides information to help make media selections and how to care for media. Media guidelines Selecting the appropriate media for the printer helps avoid printing problems.
Media specifications Curl Curl is the tendency of media to curve at its edges. Excessive curl can cause paper feeding problems. Curl can occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid, cold and dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause feeding problems. Smoothness The degree of smoothness of paper directly affects print quality.
Media specifications Selecting paper Proper paper loading helps prevent jams and ensures trouble-free printing. To help avoid jams or poor print quality: • • • • • • • • • • Always use new, undamaged paper. Before loading paper, know the recommended print side of the paper. This information is usually indicated on the paper package. Do not use paper that has been cut or trimmed by hand. Do not mix media sizes, weights, or types in the same source; mixing results in jams.
Media specifications Printing on letterhead Check with the manufacturer or vendor to determine whether the chosen preprinted letterhead is acceptable for laser printers. Page orientation is important when printing on letterhead. Use the following table for help when loading letterhead in the media sources. Media source or process Print side Top of page Trays Printed letterhead face down Letterhead goes toward the left of the tray.
Media specifications • • • • • • Set the Paper Source in the Paper Menu based on the source in use, set the Paper Type to Envelope, and select the correct envelope size from the operator panel, the printer driver, or from MarkVision Professional. For best performance, use envelopes made from 90 g/m2 (24 lb bond) paper. Use up to 105 g/m2 (28 lb bond) weight for the 250-sheet standard tray or 105 g/m2 (28 lb bond) weight for envelopes as long as the cotton content is 25% or less.
Media specifications • Remove a 3 mm (0.125 in.) strip from the leading edge to prevent labels from peeling inside the printer. • Portrait orientation is preferred, especially when printing bar codes. • Do not use labels that have exposed adhesive. Card stock Card stock is single ply, and has a large array of properties, such as the moisture content, thickness, and texture, that can significantly affect print quality.

Supporting IPSec (Internet Protocol Security) IP Security protocol provides authentication and encryption of communications at the network layer allowing all application and network communications over the IP protocol to be secure.
Administrative support Using 802.1x Authenticating 802.1x port authentication allows the printer to join networks that require authentication before allowing access. 802.1x port authentication can be used with the WPA (Wi-Fi Protected Access) feature of an optional internal wireless print server to provide WPA-Enterprise security support. Support for 802.1x requires the establishment of credentials for the printer. The printer must be known to the Authentication Server (AS).
Administrative support Printing Lockout Printing Lockout lets you lock or unlock a printer using an assigned PIN. When locked, every job the printer receives will buffer to the hard disk. A user can print jobs only by entering the correct PIN on the operator panel. You can assign a PIN through the Web page of the device. Note: This setting is only available when a hard disk is installed. Note: Back channel data will be processed while the printer is locked.
Administrative support Using the Coverage Estimator The Coverage Estimator provides you with an estimate of the percent coverage of cyan, magenta, yellow, and black toner on a page. These estimates are printed on the page. To turn on the Coverage Estimator utility: 1 Make sure your printer is on. 2 Press 3 Press until Settings appears, and then press 4 Press until Utilities Menu appears, and then press 5 Press until you see On, and then press on the operator panel. . . .
Administrative support Configuring printer alerts You can configure the printer several ways to let you know when it requires attention. Using the Setup Menu Menu item Function Value Result Alarm Control Lets you establish whether the printer sounds an alarm when it requires operator intervention.

7 Troubleshooting Online customer support Customer support is available on the Lexmark Web site at www.lexmark.com. Calling for service When you call for printer service, describe the problem you are experiencing, the message on the display, and the troubleshooting steps you have already taken to find a solution. You need to know your printer model type and serial number. See the label behind the toner waste container door of the printer for this information.
Troubleshooting Solving printing problems Symptom Cause Solution The operator panel display is blank or displays only diamonds. The printer self test failed. Turn the printer off, wait about 10 seconds, and turn the printer back on. Performing Self Test appears on the display. When the test is completed, the Ready message is displayed. If the messages do not appear, turn the printer off and call for service. The message Error reading USB drive appears when using a USB device.
Troubleshooting Symptom Cause Solution Job prints from the wrong tray or on the wrong paper or specialty media. The operator panel menu settings do not match the media loaded in the tray. Make sure the Paper Size and Paper Type specified in the printer driver match the paper size and type in the tray and what is set on the printers operator panel. Incorrect characters print. You are using an incompatible parallel cable.
Troubleshooting Solving option problems If an option does not operate correctly after it is installed or if it quits working: • Turn the printer off, wait for about 10 seconds, and turn the printer on. If this does not fix the problem, unplug the printer, and check the connection between the option and printer. • Print the menu settings page and check to see if the option is listed in the Installed Options list. If the option is not listed, reinstall it.
Troubleshooting Solving high capacity feeder problems Problem Solution The paper tray does not raise when the loading door is closed, or the paper tray does not lower when the door is opened and the paper tray button is pushed. Check the following: • The printer is properly attached to the high capacity feeder. • The printer is powered on. • The power cord is plugged firmly into the back of the high capacity feeder. • The power cord is plugged into an outlet. • The outlet has power.
Troubleshooting Solving paper feed problems Symptom Cause Solution Paper frequently jams. You are using paper that does not meet the printer specifications. Use recommended paper and other specialty media. See the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.com for detailed specifications. For information that can help prevent jams from occurring, see Avoiding jams. You have loaded too much paper or too many envelopes.
Troubleshooting The information in the following table may help you solve print quality problems. If these suggestions still do not correct the problem, call for service. You may have a printer part that requires adjustment or replacement. Symptom Cause Solution Color misregistration Color has shifted outside of the appropriate area or has been superimposed over another color area. Open the printer door, and make sure all four packaging tabs are removed.
Troubleshooting Symptom Cause Solution Streaked horizontal lines The print cartridges, the transfer roller, image transfer unit, or fuser may be defective, empty, or worn. Replace the print cartridge, the transfer roller, the image transfer unit, or fuser as needed. From the printer operator panel, print the repetitive defects guide to determine which component needs to be replaced. • Toner is smeared before fusing to the paper. • The print cartridge is defective.
Troubleshooting Symptom Cause Solution Print too light • Paper settings may be incorrect. • The Toner Darkness setting is too light. • You are using paper that does not meet the printer specifications. • The print cartridges are low on toner. • The print cartridges are defective or have been installed in more than one printer. • Make sure the printer paper type, paper texture, and paper weight settings match the type of paper you are using.
Troubleshooting Symptom Cause Solution Gray background • The Toner Darkness setting is too dark. • The print cartridges are defective. • Select a different Toner Darkness setting from the printer driver before sending the job to print. • Replace the print cartridge that corresponds to the color displayed on the control panel. • The print cartridges are defective. • The transfer roller is worn or defective. • The image transfer unit is worn or defective.
Troubleshooting Symptom Cause Solution Solid color pages • The print cartridges are defective. • Your printer requires servicing. • Replace the print cartridge that corresponds to the color displayed on the control panel. • Call for service. The paper curls badly once it prints and exits to a bin. • The Type, Texture, and Weight settings are not appropriate for the type of paper or specialty media you are using. • The paper has been stored in a high humidity environment.
Troubleshooting Should I use the PostScript or PCL emulation driver for the best color? What driver settings should I use for the best color? The PostScript driver is strongly recommended for best color quality. The default settings in the PostScript driver provide preferred color quality for the majority of printouts.
Troubleshooting How can I match a particular color (such as a color in a corporate logo)? Occasionally, users have a need for the printed color of a particular object to closely match a specific color. A typical example of this is when a user is trying to match the color of a corporate logo. While instances can occur in which the printer cannot exactly reproduce the desired color, users should be able to identify adequate color matches for the majority of cases.
Troubleshooting What are Detailed Color Samples and how do I access them? This information applies to network models only. Detailed Color Samples are pages similar to the default pages of color samples accessible from the Quality Menu on the printer operator panel or from the Configuration Menu in the printer Embedded Web Server. The default color samples accessed by these methods have an increment value of 10 percent for Red (R), Green (G), and Blue (B) values.
