20 Fax Print Quality Diagnostic Tips Because a fax is composed of three main parts spanning two different machines, pinpointing a print quality issue can be challenging. An important step in troubleshooting is to isolate the source of the print quality problem by simple troubleshooting methods. Below is a chart outlining the troubleshooting steps to determine if the sending fax, receiving fax or phone line is the problem source. Please keep in mind that this chart only covers general print quality issues. For more detailed information, it is recommended that you complete Lexmark s online course called MFP Overview. Receiving Fax Quality is poor Test Receiving Fax Print the Print Quality Pages in the Receiving Fax. Yes Do the pages look normal? No Test the Sending Fax Use the Copy function in the Sending Fax. See Receiving Fax Machine at Fault on page 40. Yes Do the pages look normal? No See Phone Line at Fault on page 40. See Sending Fax Machine at Fault on page 39. For Training Purposes Only 14

21 Sending Fax Machine at Fault Problem Description: Problems with print quality at the receiving fax, such as corrupt images, lines in the image, top/bottom cut off. When you test the Sending Fax by using the Copy function you can reproduce the print quality problem. Most Likely Cause: Resolution: Dirty flatbed or hardware failure in the scanner. Clean the flatbed glass. If the original document is being sent from the ADF, try printing a copy with the original document placed on the flatbed glass. If this solves the problem, the problem is in the ADF. For Training Purposes Only 15

22 Receiving Fax Machine at Fault Problem Description: Problems with print quality at the receiving fax, such as corrupt images, lines in the image, top/bottom cut off. When you test the Receiving Fax by printing the Self-Test pages you can reproduce the print quality problem. Most Likely Cause: Resolution: Low supplies, dirt or contamination in the printer, hardware failure. Check the supply levels by pressing the button on the operator panel or printing a Menu Settings page from the Reports menu. Check the printer for accumulation of dust or debris. Follow standard troubleshooting procedures for print quality problems. Phone Line at Fault Problem Description: Problems with print quality at the receiving fax, such as corrupt images, lines in the image, white horizontal lines, missing rows or top/bottom cut off. When you test the Sending Fax and Receiving Fax you cannot reproduce the print quality problem. The problem only occurs during faxing. Most Likely Cause: Resolution: Noise in the phone line, incoming call (call waiting), incorrect setup of dial type, line type, reception mode or electrical interference. Check/setup the dial type, line type and reception mode. If the phone line is part of a DSL connection, check to see if a Splitter (Line Filter) is installed or replace the Splitter. Disable Call Waiting if it enabled. Check the telephone line for static or other noises. Remove any electronic equipment (i.e. televisions, microwaves, etc.), motorized devices or wireless/broadcasting equipment that may be located near the fax machine. Electrical interference from the equipment may degrade the telephone line condition. For Training Purposes Only 16
