HP LaserJet Pro 500 - Step 5: Primary transfer; Step 6: Secondary transfer

Step 5: Primary transfer
The positively charged primary-transfer rollers contact the ITB, giving the ITB a positive charge. The ITB
attracts the negatively charged toner from the surface of each photosensitive drum, and the complete
toner image transfers onto the ITB, beginning with yellow, followed by magenta, cyan, and black.

Step 6: Secondary transfer
The paper acquires a positive charge from the secondary-transfer roller, and so it attracts the negatively
charged toner from the surface of the ITB. The complete toner image transfers onto the paper.
