memory does not reset the counter. Accordingly, it is necessary to
reset this counter in addition to the ordinary memory clear if the con-

of the auto feeder.
NOTE: The counter shows the operational state of the printer (how
many sheets have been printed since start of use?). The ordinary
memory does not reset the counter. Accordingly, it is necessary to
reset this counter in addition to the ordinary memory clear if the con-
tent in the memory on the control PWB is broken because of PWB
repair, etc. (In the production stage, it is necessary to execute this in
the last process.)

(For Serviceman temporary counter)
The mode is used to set a desired value for the judgment value (alarm
judgment counter value) of the general purpose life counters 1 through

etc) is set, the model which has the error display and RMS function will
inform RMS when the counter reaches the set value. For setting, pro-
ceed with the following procedure.
1. When the life counter setting mode is selected, the following will be
displayed.
The cursor blinks at the top data.
Three counters can be selected with the "#" and " " keys.
2. In the state 1, input a desired setting number of 6 digits with the
ten-key.
3. After input of 6 digits, shift to another counter with the "#" and
" " keys as necessary. When all necessary counters are com-
pletely input, press the START key.
4. "STORED" will be displayed with the set values stored into the
memory. For checking, retry this mode.
NOTE: The counter shows the operational state of the printer (how
many sheets have been printed since start of use?). The ordinary
memory does not reset the counter. Accordingly, it is necessary to
reset this counter in addition to the ordinary memory clear if the con-
tent in the memory on the control PWB is broken because of PWB
repair, etc. (In the production stage, it is necessary to execute this in
the last process.)
