A+ Exam: Electrophotographic (Ep) Laser Print Process - Quiz
About This Quiz

Electro photographic Printing or EP is a printing process that uses electrical charges, or ionized charges, to collect or repel particles from areas to be printed. The printing process basically includes six fundamental processes. How well can you identify these processes? Take our quiz to find out how well you can do.

    In electrophotography, the ______ is a fine powder that is used to create the visible image on the paper.

    Explanation
    Toner is a crucial component in electrophotography, the technology used in laser printers and photocopiers. It consists of finely ground particles that are electrostatically attracted to the charged areas of the photoreceptor drum, forming the image that is then transferred to the paper.

    What is the fourth step in the EP print process?

    Explanation
    Now that the surface of the drum holds an electrical image of the print job, a magnetic DEVELOPING roller inside the EP cartridge is charged to -600VDC. The developing roller rotates toward the photo sensitive drum. Toner sticks to this DEVELOPING roller and charges the toner to -600VDC. The toner is attracted to the -100VDC areas on the drum and repelled by the -600VDC areas. The drum now has toner stuck to it where the laser has written.

    What is the fifth step in the EP print process?

    • Fusing

    • Transferring

    • Cleaning

    • Writing

    • Charging

    Correct Answer
    A. Transferring
    Explanation
    Now the developed image is rotating into position. The registration rollers move the paper underneath the drum, and the process of TRANSFERRING the image begins. The corona wire/roller acquires a strong positive charge (+600VDC) and applies the charge to the paper. The charge pulls the toner from the drum. The static eliminator strip then removes all charge from the paper.

    What is the third step in the EP print process?

    • Developing

    • Cleaning

    • Fusing

    • Transferring

    • Writing

    Correct Answer
    A. Writing
    Explanation
    In this step the laser is turned on and scans the drum from side to side, flashing on and off according to the information received from the printer controller. Wherever the laser WRITES on the drum it reduces the charge to around -100VDC, creating the image to be printed.

    What is the first step in the EP Print Process?

    • Charging

    • Developing

    • Fusing

    • Cleaning

    • Writing

    Correct Answer
    A. Cleaning
    Explanation
    In the first part of the laser print process, a rubber blade inside the EP cartridge scrapes (CLEANS!)any toner left on the drum into a used toner receptacle, and a fluorescent lamp discharges any remaining charge on the photsensitive drum.
