6-5. Setting a PC BIOS to invoke ECP Mode
SMARTJET use ECP mode of Nibble mode when SMARTJET are transferring scanned data to a PC through
a centronics cable. Depending upon a parallel port connection (P1284) mode, scan speed of our unit can vary
in great deal, and sometimes unexpected problems like SIO chip detection problem might come up due to a
mode difference between a host PC and our unit.
When a PC is booting, a PC BIOS initializes the SIO chip of PC in parallel port and sets the mode of parallel
port. But when parallel port is set in a nibble mode, a SIO chip in some certain PCs prohibit PC software(the
twain driver) from changing the mode of parallel port. In order to enhance the speed of parallel port and to
solve some parallel port connection problems it is strongly recommended that the service man who has
encounterde these problems must set the parallel port connection(P1284) mode to a ECP mode in a PC BIOS.
