Name Timing Purpose
PRINT From the end of the INTR period until the primary
high-voltage is turned off
Forms the image on the photosensitive drum and
transfers the toner image to the media
LSTR (last
rotation)
From the end of the PRINT period (when high-voltage
is turned off) until the main motor stops rotating
Delivers the last page of a print job
After LSTR, the product either returns to STBY or, if
another print command was sent from the formatter,
enters INTR.
