The printer does not function properly
Counts are stored in battery-required memory. If the power is turned off and on again
with the battery exhausted, a problem occurs such that printing is not counted normally.
The battery needs to be replaced. Since the battery should be replaced by UNIPULSE,
contact your dealer representative. The average life of the battery is approx. 8 years. The
time may also be incorrect if the battery is exhausted.
The decimal point position printed by the M252A depends on that of the indicator side.
If the decimal point position on the indicator side is changed during printing, sub totals /
grand totals are not calculated properly.
Never change the decimal point position of the indicator during printing. Change the
decimal point position after finding grand totals and clearing print data.
Data to which over status (R print) is added is not added.
Check that over status (R print) is not added to the print data.
The over status occurs due to indicator side trouble. Troubleshoot it referring to the
instruction manual of the indicator.
Printed counts are wrong.
