(*The programs support the R & B copying function, but the current CIS units do not.
Therefore, if you press the COPY ALL key instead of the COPY key so as to activate the R &
B copying function, an error will occur in the scanning test, disabling the machine.)
Both the ERROR and PAPER LEDs go off and the machine returns to the regular operation
mode.
(8) To check that the correct page length is set, print out a dump list (refer to Subsection 4.3.4).
(9) To make sure that the R & B copying function is deactivated, press the COPY ALL key after
performing the above procedure. If images on two sides of the copyboard screen are printed
out, the R & B copying function has been deactivated; if images on a single side only is
printed out or a scanning error occurs, then the R & B copying function has been enabled, so
you need to perform the above procedure again.
