Detect with the existing method.6 not used - -7 not used - -Detailed Discussions of Bit 5When "Detect with the new method" is selected, tone is detected for 3.5 seconds before call origination in order to discriminatebetween dial tone and voice. If dial tone is detected andthe time since line seizure is 3.5 seconds or longer, call origination takes place immediately. If the time since line seizure is lessthan 3.5 seconds,call origination takes place after waiting for 1 second. (If the time since line seizure reaches 3.5 seconds during the 1-secondwaiting period, call origination takes place immediately. By default, "Detect with a new method" is assigned for this SW.● SSSW-SW32List of FunctionsBit Function 1 00 not used - -1 not used - -2 not used - -3 not used - -4 not used - -5 NCU version NCU2002 NCU20046 not used - -7 not used - -Detailed Discussions of Bit 5NCU (Network Control Unit) version can be selected.● SSSW-SW33List of FunctionsBit Function 1 00 count B4 (Print) as large size Yes No1 not used - -2 count B4 (Scan) as large size Yes No3 the counter display type change in Japan and USA * *4 * *5 Toner cartridge replacement counter display Yes No6 not used - -7 not used - -Detailed Discussions of Bit 0Use it to specify whether B4 paper (Print) should be counted as large-size paper.If 'yes' is selected, B4 paper will be counted as large-size paper.If 'no' is selected, on the other hand, B4 paper will be counted as small-size paper.8.
