Block Actions Occurring
The second or later copy cycle is begun as the copyboard begins advancing.
STEP 16CH
This is the same as STEP 4C
(repeat only)
SL7 is disenabled as the jam detection period ends. This is the same as
STEP 17CH
STEP 8CH
(last only)
The copy begins exiting the machine at the approximate time and position
STEP 17CH
shown. As in STEP 15CH (last only), this action must occur before a
(repeat only)
drum position of 50° .
Copy paper now finishes exiting the copier and the jam detection circuit resumes
STEP 18CH
its quiescent condition as in
STEP IOCH
As the copyboard is no longer moving, K 10 has remained deenergized since
STEP 19CH
-STEP 13CH
Thus, the MS3A pulse acts to turn K11 OFF. The jam detection
circuit is now deactivated in preparation for the STANDBY condition.
Although the drum position and time are different, this step is the same as
STEP 20CH
STEP SS ;that is, completion of the feed interval as capacitor C16 com-
pletes its discharging.
STEP 21CH
The delay hold path for relay K7 is broken at this time as in STEP 6S
The alternate path for the main motor is broken, stopping the drum. This is the
STEP 22CH
same as STEP 7S
The machine is now in STANDBY awaiting the depressing of the COPY button
to start the next copy operation.
