CHAPTER 2 OPERATION AND TIMING
2-82
The pick-up/feed system can be divided into the following two blocks:
• Pick-up/feed unit: pick-up source to fixing unit inlet
• Fixing/delivery unit: fixing unit to delivery source
F02-501-02
Each block is described next.
5.2 Pick-up/Feed Unit
5.2.1 Outline
The pick-up/feed unit is structured with a pick-up unit, which feeds paper into the printer
one by one from the multi-purpose tray, and a feed unit, which feeds the picked-up paper to
the fixing unit.
The mechanisms of the pick-up/feed unit are described below.
<Multi-purpose tray pick-up>
1) Pick-up operation from the multi-purpose tray
<Paper feed>
1) Skew calibration function
2) Feed speed control based on the paper type
3) Feed speed control by internal temperature detection
