Remove excess paper from the tray. • An incorrect type of paper is being used. Use only paper that meets the specifications required by the machine. See “Paper Specifications” on page A.5. If you are printing on special materials, use the manual feeder. • There may be debris inside the machine. Open the front cover and remove the debris. Transparencies stick together in the paper exit. Use only the transparencies specifically designed for a laser printer. Remove each transparency as it exits from the machine. Envelopes skew or fail to feed correctly. Ensure that the paper guides are against both sides of the envelopes. 6.8 TROUBLESHOOTING Copying Problems Condition Suggested solutions Copies are too light or too dark. Use the Darkness button to darken or lighten the background of the copies. Smears, lines, marks or spots appears on copies. • If defects are on the original document, press the Darkness button to lighten the background of your copies. • If no defects are on the original document, clean the scan unit. See page 5.4. Copy image is skewed. • Ensure that the original document is positioned correctly in the ADF (Automatic Document Feeder). • Check that the copy paper is loaded correctly. Blank copies print out. Ensure that the original document is face down in the ADF. 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. Faxing Problems Condition Suggested solutions The machine is not working, there is no display and the buttons are not working. • Unplug the power cord and plug it in again. • Ensure that there is power to the electrical receptacle. No dial tone sounds. • Check that the phone line is connected properly. • Check that the phone socket in the wall is working by plugging in another phone. The numbers stored in the memory do not dial correctly. Make sure that the numbers are stored in the memory correctly. Print a Phonebook list, referring to page 2.15. The document does not feed into the machine. • Make sure that the document is not wrinkled and you are putting it in correctly. Check that the document is the right size, not too thick or thin. • Make sure that the control panel is firmly closed. 6 TROUBLESHOOTING 6.9 Condition Suggested solutions Faxes are not received automatically. • Fax mode should be selected. • Make sure that there is paper in the tray. • Check to see if the display shows “Memory Full.” The machine does not send. • Make sure that the document is loaded in the ADF. • “TX” should show up on the display. • Check the other fax machine you are sending to, to see if it can receive your fax. The incoming fax has blank spaces or is received with a poor-quality. • The fax machine sending you the fax may be faulty. • A noisy phone line can cause line errors. • Check your machine by making a copy. • The toner cartridge may be empty. Replace the toner cartridge, referring to page 5.7. Some of the words on a incoming fax are stretched. The fax machine sending you the fax had a temporary document jam. There are lines on the documents you send. Check your scan unit for marks and clean it. See page 5.4. The machine dials a number, but a connection with another fax machine fails. The other fax machine may be turned off, out of paper, or cannot answer incoming calls. Speak with the other machine operator and ask her/him to clear out the problem. Documents are not stored in the memory. There may not be enough memory to store the document. If the display shows a “Memory Full” message, delete any documents you no longer need from the memory and then restore the document. Blank areas appear at the bottom of each page or on other pages, with a small strip of text at the top. You may have chosen the wrong paper settings in the user option setting.
