Rapid key 11: Life entry mode
(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
3 of the printer. If the life of a consumable part (developer, imprinter, etc)
is set, the model which has the error display and RMS function will in-
form RMS when the counter reaches the set value. For setting, proceed
with the following procedure.

The cursor blinks at the top data.
Three counters can be selected with the "#" and " " keys.

In the state

keys as necessary. When all necessary counters are completely in-
put, press the START key.

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 content in the memory on the control PWB is broken be-
cause of PWB repair, etc. (In the production stage, it is neces-
sary to execute this in the last process.)
