My product's control panel locks up after I print a document from Windows. The buttons on the panel do not respond unless I disconnect the parallel cable from the back of my product. What should I do?
Some computers send an initialize/reset signal during the boot-up process. If the printer cable picks up any noise during this process, the initialize line will not complete its reset phase and cause the control panel to lock. Try booting the computer to Windows, then turn the printer ON using the printer's power switch and try printing again. A defective cable can also cause this situation. Make sure you are using a fully-shielded parallel cable, preferably 6 feet or less.
