Resumen del manual
Loose toner • Clean the inside of the machine (see "Cleaning the machine" on page 70). • Check the paper type and quality. • Remove the toner cartridge and then, install a new one (see "Replacing the toner cartridge" on page 66). If the problem persists, the machine may require repair. Contact a service representative. Character voids A Character voids are white areas within parts of characters that should be solid black: • You may be printing on the wrong surface of the paper. Remove the paper and turn it around. • The paper may not meet paper specifications. 5. Troubleshooting 193 Printing quality problems Condition Suggested solutions Horizontal stripes If horizontally aligned black streaks or smears appear: • The toner cartridge may be installed improperly. Remove the cartridge and reinsert it. • The toner cartridge may be defective. Remove the toner cartridge and install a new one (see "Replacing the toner cartridge" on page 66). If the problem persists, the machine may require repairing. Contact a service representative. Curl If the printed paper is curled or paper does not feed into the machine: • Turn the stack of paper over in the tray. Also try rotating the paper 180° in the tray. • Change the printer’s paper option and try again. Go to Printing Preferences, click the Paper tab, and set type to Thin (see "Opening printing preferences" on page 48). • An unknown image repetitively appears on a few sheets • Loose toner • Light print or contamination occurs Your machine is probably being used at an altitude of 1,000 m (3,281 ft) or above. The high altitude may affect the print quality, such as loose toner or light imaging. Change the altitude setting for your machine (See "Altitude adjustment" on page 133). 5. Troubleshooting 194 Copying problems Condition Suggested solutions Copies are too light or too dark. Adjust the darkness in copy feature to lighten or darken the backgrounds of copies (see "Changing the settings for each copy" on page 50). Smears, lines, marks, or spots appear on copies. • If the defects are on the original, adjust darkness in copy feature to lighten the background of your copies. • If there are no defects on the original, clean the scan unit (see "Cleaning the scan unit" on page 74). Copy image is skewed. • Ensure that the original is aligned with the registration guide. • The transfer roller may be dirty. Clean the inside of your machine (see "Cleaning the machine" on page 70). Blank copies print out. Ensure that the original is face down in the document feeder. If these steps do not correct the problem, contact a service representative. Image rubs off the copy easily. • Replace the paper in the tray with paper from a new package. • In high humidity areas, do not leave paper in the machine for extended periods of time. Frequent copy paper jams occur. • Fan the paper, then turn it over in the 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 type and weight. • Check for copy paper or pieces of copy paper remaining in the machine after a paper jam has been cleared. Toner cartridge produces fewer copies than expected before running out of toner. • Your originals may contain pictures, solids, or heavy lines. For example, your originals may be forms, newsletters, books, or other documents that use more toner. • Turn the machine off and back on. 5. Troubleshooting 195 Scanning problems Condition Suggested solutions The scanner does not work. • Make sure that you place the original to be scanned face down in the document feeder (see "Loading originals" on page 44). • There may not be enough available memory to hold the document you want to scan. Try the Prescan function to see if that works. Try lowering the scan resolution rate. • Check that the machine printer cable is connected properly. • Make sure that the machine printer cable is not defective. Switch the printer cable with a known good cable. If necessary, replace the printer cable. • Check that the scanner is configured correctly. Check scan setting in the SmarThru Office or the application you want to use to make certain that the scanner job is being sent to the correct port (for example, USB001). The unit scans very slowly. • Check if the machine is printing received data. If so, scan the document after the received data has been printed. • Graphics are scanned more slowly than text. • Communication speed slows in scan mode because of the large amount of memory required to analyze and reproduce the scanned image. Set your computer to the ECP printer mode through BIOS setting. It will help to increase the speed. For details about how to set BIOS, refer to your computer user’s guide. 5. Troubleshooting 196 Scanning problems Scanning problems Condition Message appears on your computer screen: • Device can’t be set to the H/W mode you want. • Port is being used by another program. •Port is disabled. • Scanner is busy receiving or printing ...
