  3. Development: Toner particles within the toner cartridge are attracted to the electrostatic image on the drum, forming a visible image.
  4. Transfer: The developed image is transferred onto the paper as it passes through the printer.
  5. Fusing: The toner is then fused to the paper using heat, resulting in the final printed page.


The HP 19A Imaging Unit is a crucial component of your HP LaserJet printer, playing a significant role in ensuring the high-quality, consistent, and reliable prints you expect.
