A+ Exam: Electrophotographic (Ep) Laser Print Process
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.

Correct Answer
D. CleaningExplanation
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.Rate this question:

What is the second step in the EP print process?
Correct Answer
ChargingExplanation
In this step, a special wire or roller (the charging corona) within the EP toner cartridge gets a high voltage and uses it to apply a strong negative CHARGE (-600VDC) to the photosensitive drum.Rate this question:

- A.
Developing
- B.
Cleaning
- C.
Fusing
- D.
Transferring

Writing
Correct Answer
E. WritingExplanation
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.Rate this question:

What is the fourth step in the EP print process?
Correct Answer
DevelopingExplanation
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.Rate this question:

What is the fifth step in the EP print process?
- A.
Fusing
- B.
Transferring
- C.
Cleaning
- D.
Writing
- E.
Charging
Correct Answer
B. TransferringExplanation
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.Rate this question:

What is the sixth step in the EP print process?
Correct Answer
FusingExplanation
In the final step, the print image is made permanent. The registration rollers push the paper toward the fuser rollers. The 350 degree fuser takes control and melts the polyester resin of the toner, and the rubberized pressure roller presses it permanently into the paper. The paper continues until it exits the paper. The printer then trips a sensor to start the cleaning step all over again.Rate this question:
