10. Image Transfer
●
A single-wire transfer corona generates a positive DC corona discharge on the back
side of the sheet being fed. This causes the visible image on the PC drum to transfer
onto the front side of the paper.
11. Separation (1)
●
A single-wire separator corona generates AC and negative DC corona discharges at
the backside of the sheet so that the sheet can be easily separated from the drum.
12. Separation (2)
●
The sheet is removed from the drum by the PC-Drum Separation Fingers.
13. Cleaning
●
The cleaning blade removes the toner remaining on the drum.
14. Main Erase
●
The drum is exposed to light to remove any residual surface charge.
15. Transport
●
The suction belt moves the sheet to the fusing section.
16. Fusing
●
Heat and pressure supplied by the upper and lower fusing rollers cause the toner to
fuse to the sheet.
17. Upper Paper Exit Switch
●
The switching mechanism determines whether the sheet is ejected to the copy tray or
transported to the turnover section.
18. Turnover
●
This section flips the sheet and directs it onward. The sheet is then either ejected (if a
one-side copy) or else transported to the duplex unit (if the sheet must be passed
through again for duplex copying).
19. Duplex Unit
●
Stores (following first-side copy) a fixed number of sheets that have been ejected. Then
refeeds the sheets for copying onto the other side.
20. Lower Paper Exit Switch
●
This switch operates only during folded sorting mode. The solenoid comes ON, causing
paper to eject with no turnover.
