10-26 Troubleshooting Chapter 10Technical NotesUsing Other Bi-directional DevicesIf you have another bi-directional device (such as a Windows PrintingSystem printer or a later-model laser printer) installed on your computerand you are attempting to use the same port on which you have theMultiPASS connected, you may experience undesirable results whenprinting a document.Be sure the MultiPASS is the only device configured to a particular port.The MultiPASS operates properly only with a dedicated parallel port.(Note that you can set the WPS driver to file, or use a PCL emulationdriver for the WPS printer, or install a second parallel port—one for eachprinter.)MultiPASS Hardware Cannot Initialize1. Remove any pass-through devices, switch boxes, zip drives, tapebackups, docking stations, scanners, and any software associated withthese products.2. Make sure that the MultiPASS is connected directly to the computerwith a bi-directional (IEEE 1284-compliant) interface cable that is 6feet or shorter. Do not attempt to use a longer cable.3. Shut down the computer and unplug the MultiPASS. Disconnect andreconnect the interface cable. Plug in the MultiPASS and wait untilthe LCD displays the date and Receive Mode. Once the unit is inStandby mode (the LCD displays the date and Receive Mode), turn onthe computer.4. Check that the parallel port is set for ECP or bi-directional mode inthe computer’s BIOS. If you do not know how to enter the BIOS ormake the changes, contact the computer manufacturer.5. If the above procedures do not resolve the problem, please call the CanonComputer System Customer Care Center. See page 1-2 for details.
