Check that the printer has plenty of paper. Some printers will not start printing when there are just two or three sheets of paper left in the tray. Make sure the printer cable is firmly attached to the computer and the printer. Run the printer’s self-test to check for any problem with the printer itself. Make sure you installed the proper printer drivers, as shown in “Connecting a local printer” on page 64. You may have connected the printer while the computer is on. Disable Stand By mode, turn off the computer, and turn off the printer. Turn the printer back on, make sure it is on line, then turn the computer back on. Try printing another file. For example, you could create and attempt to print a short test file using Notepad. If a Notepad file prints correctly, the problem may be in your original file. If you cannot resolve the problem, contact the printer’s manufacturer. The printer will not print what you see on the screen. Many programs display information on the screen differently from the way they print it. See if your program has a print preview mode. This mode lets you see your work exactly as it will print. Contact the software manufacturer for more information. Modem problems This section lists common modem problems: The modem will not receive or transmit properly. Make sure the cable from the modem to the telephone line is firmly connected to the computer’s modem port and the telephone line jack. Check the port settings to make sure the hardware and software are referring to the same COM port. Check the communications parameters (baud rate, parity, data length and stop bits) specified in the communications program. It should be set up to transmit at 300, 1200, 2400, 4800, 9600, 14400, 28800, 33600 bps (bits per second), or higher. Refer to the program’s documentation and the modem manual for information on how to change these settings. The modem is on, set up properly and still will not transmit or receive data. Make sure the line has a dial tone. Connect a telephone handset to the line to check this. The other system may be busy or off line. Try making a test transmission to someone else. Develop good computing habits Make sure you are prepared. Save your work frequently. You can never predict when your computer will lock, forcing you to close a program and lose unsaved changes. Many software programs build in an automatic backup, but you should not rely solely on this feature. Save your work! See “Computing tips” on page 75 for instructions. On a regular basis, back up the information stored on your hard disk. Here are some ways you can do this: . Copy files to diskette, following the steps in “Saving your work” on page 83. . Connect a tape drive to the system and use specialized software to copy everything on the hard disk to a tape. Some people use a combination of these methods, backing up all files to tape weekly and copying critical files to diskette on a daily basis. If you have installed you...
