- A.
Writing
- B.
Transferring
- C.
Developing
- D.
Cleaning
Correct Answer
A. WritingExplanation
The step in the EP print process that uses a laser to discharge selected areas of the photosensitive drum, thus forming an image on the drum, is called "Writing". During this step, the laser beam is used to create a pattern of electrical charges on the drum's surface, which corresponds to the image that needs to be printed. This charged pattern will attract the toner particles in the next step, resulting in the formation of the image on the drum.Rate this question:

Cleaning, charging, writing, developing, transferring, fusing
Correct Answer
D. Cleaning, charging, writing, developing, transferring, fusingExplanation
The correct order of the steps in the EP print process is as follows: first, the cleaning step is performed to remove any residual toner or debris from previous prints. Then, the charging step takes place, where a charge is applied to the drum or photoconductor to prepare it for the next step. Next, the writing step occurs, where a laser or other light source is used to create an electrostatic image on the drum or photoconductor. After that, the developing step takes place, where toner particles are attracted to the charged areas on the drum or photoconductor to form the image. The transferring step follows, where the toner image is transferred onto the paper or other media. Finally, the fusing step occurs, where heat and pressure are applied to the toner to melt it and permanently bond it to the paper.Rate this question:

Which type of printers can be used with multipart forms?
- A.
Bubble-jet printers
- B.
EP process laser printers
- C.
HP process laser printers
- D.
Dot-matrix printers
Correct Answer
D. Dot-matrix printersExplanation
Dot-matrix printers can be used with multipart forms because they have the ability to create multiple copies of a document simultaneously. Multipart forms typically consist of multiple layers, and dot-matrix printers use impact printing technology to create these copies by striking an inked ribbon against the paper, transferring the ink onto the desired layers. This makes dot-matrix printers suitable for applications such as invoices, receipts, and other forms that require multiple copies to be generated at once. Bubble-jet printers, EP process laser printers, and HP process laser printers do not have the same capability to create multipart forms.Rate this question:
