Copying Problems Condition Suggested solutions Copies are too light or too dark. Use the "Darkness" feature to darken or lighten the background of the copies. Smears, lines, marks or spots appears on copies. • If defects are on the original document, use the "Darkness" feature to lighten the background of your copies. • If no defects are on the original document, clean the document glass and underside of the document cover. See page 7.5. Copy image is skewed. • Ensure that the original document is positioned correctly on the document glass. • Check that the copy paper is loaded correctly. Blank copies print out. Ensure that the original document is face down on the document glass. Image rubs off the copy easily. • Replace the paper in the paper tray with paper from a new package. • In high humidity areas, do not leave paper in the machine for the extended periods of time. Frequent copy paper jams occurs. • Fan the stack of paper, then turn it over in the paper tray. Replace the paper in the tray with a fresh supply. Check/adjust the paper guides, if necessary. • Ensure that the paper is the proper paper weight. 75g/m2 (20 lb) bond paper is recommended. • Check for copy paper or pieces of copy paper remaining in the machine after a paper jam has been cleared. Fewer copies from the toner cartridge than expected prints out. • Your original documents may contain pictures, solids or heavy lines. For example, they may be forms, newsletters, books or other documents that use more toner. • The machine may be turned frequently on and off. • The document cover may be left open while copies are being made. 8.18 TROUBLESHOOTING
