The photoconductor properties are such that when the laser 'writes' the data on it, the magnetic properties are changed to conform to the printed data...in a mirror image . The drum, with the characters , then rotates thru' the toner and picks up toner only where the characters are. The 'characters' are then transferred to the electrically charged paper, which picks up the characters. The paper then must go into the fuser which bonds or melts the image onto the paper. Edah1144

What is photoconductor unit inlaser printer?
Otherwise known as the drum kit. Quite often the laser printer will tell you (on the LCD display) that you need to replace the photoconductor, but the price list will have no such thing. It will however usually list a Drum Kit.
When servicing a laser printer a photoconductor needs to be well removed from what element?

Where on a dell printer is the photo conductor?
On a Dell printer, the photoconductor unit is typically located inside the printer, often integrated with the toner cartridge or as a separate component depending on the model. To access it, you usually need to open the front cover and remove the toner cartridge. The photoconductor can usually be identified by its shiny surface and may require periodic replacement to maintain print quality. Always refer to the specific printer's manual for detailed instructions on locating and replacing the photoconductor.
How does a photostat machine works?
I have read it back in my High School that some metals have photoelectric effect, i.e. a charge is generated on them when light falls on them. Selenium, Cadmium are some of the common elements that demonstrate photoelectric effect. Nowadays amorphous silicon being used as a photoconductor in the photocopying machines. When a reflection from the original falls on the photoconductor unit then there is a charge difference in the areas where the document is blank and where it is printed. This makes the photoconductor surface charged unevenly. At this time, the toner which is again a charged colloidal powder (charged opposite to the charge generated on the photoconductor) is applied on the surface and it sticks to the areas where the photoconductor is charged. Thus the image is formed on the photoconductor unit. In order to transfer this image to paper, a transfer charge is applied on the paper which again is of opposite nature than the charge of toner. Thus the charge generated on paper attracts the toner particles and thus the image is transferred to the paper. This paper then goes into the fuser section where the toner is melt by applying heat and pressure and thus fixed. The final product is a photocopy.

What is a photo conductor?
A photoconductor is something whose resistance decreases when it's exposure to light increases. As for photography, the only link I know of is that they are used in light meters.
What is the meaning of reset pcu correctly Ricoh Copier?
It means your photoconductor unit is out of whack.If you open the printer, remove your PCU, and reseat it correctly, the error message likely will disappear.
What is the charge on the paper during the image transfer phase?
During the image transfer phase of printing, the paper is given a charge that is opposite to that of the toner particles. This helps to attract and transfer the toner from the photoconductor drum to the paper.
What is the use of selenium photocells?
Because of its photovoltaic and photoconductive properties, selenium is used in photocopying, photocells, light meters and solar cells. Its use as a photoconductor in plain-paper copiers once was a leading application but in the 1980s, the photoconductor application declined (although it was still a large end-use) as more and more copiers switched to the use of organic photoconductors. It was once widely used in selenium rectifiers.

How does Photostat machine work?
Ah, the Photostat machine is a wonderful tool that creates copies of documents or images. It works by shining a bright light onto the original document and then capturing the image onto a light-sensitive photoreceptive drum. This drum then transfers the image onto a piece of paper, creating a perfect copy of the original. Just like painting a happy little picture, the Photostat machine helps us share and preserve important information with ease.
