Bottle
waste toner near full condition has been detected.
The number of prints made is counted.
(The counter counts up 2 for paper whose sub scan
direction exceeds 216 mm.)
The number of prints made is compared with the
value of the number of hours through which the

responding value of the number of prints made and
the value, whichever reaches the life specification
