Scanning Problems Condition Suggested solutions The scanner does not work. • Make sure that you place the document to be scanned face down on the document glass, or face up in the Automatic Document Feeder. • 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 USB or parallel cable is connected properly. • Make sure that the USB or parallel cable is not defective. Switch the cable with a known good cable. If necessary, replace the cable. • If you are using a parallel cable, ensure that it is compliant with IEEE 1284 standards. • Check that the scanner is configured correctly. Check scan setting in the SmarThru Configuration or the application you want to use to make certain that the scanner job is being sent to the correct port, for example, LPT1. 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. Fax Problems (Only for SCX-4521F) 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 outlet. 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 memory do not dial correctly. Make sure that the numbers are stored in memory correctly. Print a Phonebook list, referring to "Phonebook List" on page 7.13. Condition Suggested solutions 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 ADF (Automatic Document Feeder) cover is firmly closed. 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 or on the document glass. • "TX" should show up on the display. • Check the fax machine you are sending to, to see if it can receive your fax. The incoming fax has blank spaces or is of 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 "Replacing the Toner Cartridge" on page 8.4. Some of the words on an 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 scanning glass for marks and clean it. See "Cleaning the Scan Unit" on page 8.3. The machine dials a number, but a connection with the other 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 sort out the problem. Documents are not stored in memory. There may not be enough memory to store the document. If the display shows a "Memory Full" message, delete from memory any documents you no longer need and then try again to store 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. For details about paper settings, see "Setting the Paper Size and Type" on page 2.11. 9.11 Troubleshooting
