Laser Printing Process
While some documentation may list the following steps in a different order, the following sequence is what CompTIA will use for the exam.

• Clean - Before printing, the drum must be cleaned.
• Charge - Drum is charged with a negative charge (between ~600 and ~1000 volts) to receive new images.
• Write - A laser is used to write a positively charged image to the surface of the drum.
• Develop - Charged image attracts toner.
• Transfer - The transfer corona applies a positive charge to the paper.
• Fuse - The fuser melts the toner onto the paper.
