PM TABLES
B147/B149/B190 2-2 SM
2.2 PM TABLES
On the B190, there is a wider gap between sheets of paper. Since the PM interval
is based on the number of motor revolutions, increasing the paper interval means
shortening the PM interval by 10% (motor revolutions are more frequent, making
the PM timing sooner).
