Wi-Fi and Network Connection Problems

• Wrong Wi-Fi password: Re-enter the network name and password carefully using the printer control panel or setup utility.
• Weak wireless signal: Move the printer closer to the router and reduce interference from walls, appliances, and other wireless devices.
• Printer has changed IP address: Print a network setup page and update the printer port on the computer if necessary.
• Computer and printer on different networks: Make sure both devices are connected to the same router and network segment.
• Firewall blocks printing: Allow Lexmark software, printing services, and the printer's network address through the firewall.

Ethernet and Office Network Problems

• Network cable disconnected: Check both ends of the Ethernet cable and verify link lights on the printer and network equipment.
• Incorrect IP configuration: Confirm DHCP, static IP address, subnet mask, gateway, and DNS settings.
• Duplicate IP address: Assign a unique address or restart the network devices to renew DHCP assignments.
• Print server unavailable: Check the server, print queue, permissions, driver deployment, and network connection.
• Embedded Web Server unavailable: Confirm the printer IP address and verify that web access is allowed on the network.

Scanning Problems

• Scanner not detected: Check the USB or network connection and install the correct Lexmark scan software or driver.
• Document feeder does not pull paper: Align originals, adjust guides, clean the feeder rollers, and remove staples or damaged pages.
• Scans are crooked: Place the document squarely on the scanner glass or align the paper guides in the automatic document feeder.
• Scans have lines: Clean the scanner glass and the narrow feeder glass strip with a lint-free cloth.
• Scan to email fails: Check SMTP server, port, authentication, encryption, DNS, date, time, and network settings.

Copying Problems

• Copies are too light: Increase copy darkness and inspect toner and imaging supplies.
• Copies are cut off: Select the correct paper size, original size, scaling, orientation, and tray settings.
• Copy quality is poor: Clean the scanner glass and feeder glass, then adjust darkness and content type.
• Automatic document feeder jams: Remove damaged originals, clean rollers, and reload documents below the capacity limit.
• Blank copies: Place the original face down on the scanner glass or in the correct orientation in the feeder.

Fax Problems

• Fax will not send: Check the phone line, fax number, dialing prefix, line type, and whether another device is using the line.
• Fax will not receive: Check receive mode, ring count, fax memory, paper supply, and line connection.
• Poor fax quality: Clean the scanner glass, increase resolution, and verify the phone line quality.
• No dial tone: Test the wall jack and phone cable with a standard telephone.

• Memory full: Reduce document resolution or complexity, divide the job, or add memory where supported.
• Service error repeats: Record the complete error code, restart the printer, and consult the model-specific service guidance.

Printer Is Slow or Stops During Jobs

• High-resolution job: Large images, complex PDFs, and high-resolution settings can increase processing time.
• Power-saving mode active: The printer may take additional time to warm up from sleep or hibernation.
• Network congestion: Test the printer through USB or Ethernet and check router, server, and print-queue performance.
• Insufficient printer memory: Simplify the document, reduce image quality, or install supported memory where applicable.
• Incorrect driver: Install the model-specific Lexmark driver instead of a generic driver.

Routine Maintenance Tips

• Turn off before cleaning: Switch off and unplug the printer before cleaning internal areas unless the manual instructs otherwise.
• Use a dry, lint-free cloth: Clean the exterior, scanner glass, and accessible paper paths without spraying liquid directly on the printer.
• Keep paper dry: Store paper flat in a cool, dry location and keep unused reams sealed.
• Replace supplies correctly: Use the exact toner, imaging unit, waste container, fuser, and maintenance kit specified for the printer.
• Print configuration pages: Keep network, menu, supply, and device statistics pages for troubleshooting and maintenance records.

Safety note: Always turn off and unplug the printer before clearing difficult jams, cleaning internal areas, or replacing components unless the manual specifically instructs otherwise. The fuser and nearby parts may remain very hot after printing. Do not touch electrical contacts, exposed wiring, or hot internal surfaces.
