Feed transparencies from the standard tray or the multipurpose feeder. Try a sample of any transparencies being considered for use with the printer before buying large quantities. When printing on transparencies: Be sure to set the Paper Type to Transparency from the printer driver or from MarkVision Professional to avoid damaging the printer. Use transparencies designed specifically for laser printers. Transparencies must be able to withstand temperatures of 230C (446F) without melting, discoloring, offsetting or releasing hazardous emissions. To prevent print quality problems, avoid getting fingerprints on the transparencies. Before loading transparencies, fan the stack to prevent sheets from sticking together.

Selecting transparencies

The printer can print directly on transparencies designed for use in laser printers. Print quality and durability depend on the transparency used. Always print samples on the transparencies being considered for use before buying large quantities. Lexmark recommends Lexmark Part Number 12A8240 letter size transparency and Lexmark Part Number 12A8241 for A4 size transparency. The Paper Type setting should be set to Transparency to help prevent jams. (See Paper Type in the Menus and Messages Guide on the publications CD for detailed information about this setting.) Check with the manufacturer or vendor to determine whether the transparencies are compatible with laser printers that heat transparencies to 230C (446F). Use only transparencies that are able to withstand these temperatures without melting, discoloring, offsetting, or releasing hazardous emissions. For detailed information, see the Card Stock & Label Guide, which is available on the Lexmark Web site at www.lexmark.com/publications.
Try a sample of any envelopes in consideration for use with the printer before buying large quantities. See Loading the multipurpose feeder for instructions on loading envelopes. When printing on envelopes: To achieve the best possible print quality, use only high-quality envelopes that are designed for use in laser printers.

Using the duplex function (two-sided printing) 83

Avoiding jams

Use appropriate print media (paper, transparencies, labels, and card stock) to help ensure trouble-free printing. See Identifying media sources and specifications for more information. Note: Try a limited sample of any print media you are considering using with the printer before purchasing large quantities. By selecting the appropriate print media and loading it properly, you can avoid most jams. See Loading standard trays and optional trays, Loading the multipurpose feeder, or Loading the high capacity feeder for detailed tray loading instructions. The following hints can help you avoid jams: Use only recommended print media. Do not overload the print media sources. Make sure the stack height does not exceed the maximum height indicated by the stack line on the labels in the sources. Do not load wrinkled, creased, damp, or curled print media. Flex, fan, and straighten print media before you load it. If jams do occur with print media, try feeding one sheet at a time through the multipurpose feeder. Do not use print media that you have cut or trimmed yourself. Do not mix print media sizes, weights, or types in the same print media source. Make sure the recommended print side is loaded in the source according to your simplex or duplex needs. Keep print media stored in an acceptable environment. See Storing media. Do not remove trays during a print job. Push all trays in firmly after loading them.
Make sure the guides in the trays are properly positioned for the size of print media you have loaded. Make sure the guides are not placed too tightly against the stack of print media.

Avoiding jams 84

Maintaining the printer
Periodically, you need to complete certain tasks to maintain optimum print quality. These tasks are covered in this chapter. If several people are using the printer, you may want to designate a key operator to do the setup and maintenance of your printer. Refer printing problems and maintenance tasks to this key operator. In the U.S., contact Lexmark at 1-800-539-6275 for information about Lexmark Authorized Supplies Dealers in your area. In other countries or regions, visit the Lexmark Web site at www.lexmark.com or contact the place where you bought your printer.

Storing supplies

Choose a cool, clean storage area for your printer supplies. Store supplies right side up in their original packaging until you are ready to use them. Do not expose supplies to: Direct sunlight Temperatures above 35C (95F) High humidity (above 80%) Salty air Corrosive gases Heavy dust

Turn the printer off. Note: Disabling the operator panel menus does not prevent access to Print and Hold functionality.

Two types of authentication are supported for IPSec: Shared Key AuthenticationAny ASCII phrase shared among all the participating hosts. This is the easiest way to configure when only a few hosts on the network use IPSec. Certificate AuthenticationAllows any hosts or subnet of hosts to authenticate for IPSec. Each host must have a public/private key pair. Validate Peer Certificate is enabled by default, requiring each host to have a signed certificate and the authority certificate must be installed. Each host must have its identifier in the Subject Alternate Name of the signed certificate. Note: After a device is configured for IPSec with a host, IPSec is required for any IP communication to take place.

Using Secure mode

You can configure the TCP and UDP ports to one of three modes: DisabledNever allows network connections to this port. Secure and UnsecureAllows the port to remain open, even in Secure mode. Unsecured OnlyAllows the port to only open when the printer is not in Secure mode. Note: A password must be set to enable Secure mode. Once enabled, only the ports set to Secure and Unsecure will be open. To configure the Secure mode for TCP and UDP ports from the Embedded Web Server:
Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the format: http://ip_address/. Click Configuration. Under Other Settings, click Network/Ports. Click TCP/IP Port Access. Note: Disabling ports will disable function on the printer.
Setting security using the Embedded Web Server (EWS) 134
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). The AS will allow network access to devices presenting a valid set of credentials which typically involves a name/password combination and possibly a certificate. The AS will allow network access to printers presenting a valid set of credentials. You can manage the credentials by using the Embedded Web Server of the printer. To use certificates as part of the credentials:
