• Selectors 4 and 5: Command flag detection time
After receiving a command flag, the machine will wait for the command that should follow
for the time length specified by these selectors.
• Selector 8: Black ink print mode
If any color ink runs out, printing is no longer possible by default. Setting this selector to
"1" allows the machine to ignore the ink empty state and print data with black ink only,
resulting in a printout missing color components.
Note: The assurance mode switch setting made by Selector 3 on AMS04 (triggered with
function code 88 described in Chapter 9, Section 9.4.29 ) allows the machine to print all
color and black data as a monochrome printer with black ink only.
WSW50
(SDAA settings)
Note: WSW50 is applicable to models equipped with an SDAA circuit.
• Selectors 5 and 6: Current control to be applied immediately after connection of the line
FAX models equipped with an SDAA circuit (on which an NTU chip is mounted) might
not be connected to a broad band line such as an ADSL (Asynchronous Digital Subscriber
Line) in a stable condition. If those models fail to connect to such a line, try to change the
current control to be applied immediately after connection of the line by using selectors 5
and 6.
If selectors 5 and 6 are set to "0" and "1," respectively, the SDAA draws more current,
decreasing the period required to terminate the current control. If they are set to "1" and
"0," the SDAA finely controls precision of the termination current against the voltage to
approach nearer to the specified DC curve that specifies the current vs. voltage
characteristics of the network termination. Selecting either control may solve an unstable
connection problem.
