Bi-directional Parallel Ports (nibble and byte modes)
The machine supports both nibble (AT) and byte (Bi-directional) mode parallel ports. If your PC supports byte mode, scanning and fax reception will be at a faster speed. To verify or change the parallel port mode, please check your system BIOS in the CMOS Setup or contact your computer manufacturer for assistance.
Some older PC models support only nibble mode. Generally, newer models support both nibble and byte modes.
The Machine Connect Failure or Bi-directional Communication Error
Recently, some printers have included a function to show the printer status on the PC display. Such printers use the bi-directional communication parallel port between the printer and the PC. Our machine also has a bi-directional parallel port function. Since Windows® 3.xx does not support bi-directional communication on the parallel port, each peripheral vendor has developed and supplies their own bi- directional device driver, which will be installed into Windows® 3.xx. If you install two or more different bi-directional device drivers into Windows® , they might conflict with each other and cause some problems.
Please make sure you have installed the machine driver by running SETUP.EXE from your CD-ROM drive, as instructed on the CD-ROM label. The bi-directional communication may be disabled when the driver is installed from Add menu in “Printers” of Control Panel. Please restart Windows® after installing the drivers.
Remove the conflicting situation caused by one of the following printer drivers. Review the following sections that apply to any additional printer drivers you may have installed into your Windows® software.
