be executed. The detailed specifications of each mode are described as
follows. Here, the operation in each mode is stopped only when the STOP
key is pressed by the operator or a printing-impossible error occurs.

In the state , input a desired setting number of 6 digits with the
ten-key.

After input of 6 digits, shift to another counter with the "#" and "
keys as necessary. When all necessary counters are completely
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? and others). The ordi-
nary memory does not reset the counter. For clearing, set 0 in this
mode or use the life counter clear mode in Item 3-9. (Accordingly, it is
necessary to reset the counter or do the clear process in addition to
the ordinary memory clear if the content 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.)
