its called the drumhead
the head If you mean a drummers drumstick it is called the tip.
Its the central part of the laser printer. The drum is a metal cylinder that is coated with a light-sensitive insulating material. When a beam of laser light strikes the drum, it becomes a conductor at the point where the light hits it. As the drum rotates, the laser beam draws an electrostatic image upon the drum, called the image. The undeveloped or latent image is passed by a supply of dry ink or toner that is attracted to it. The drum turns and brings this image in contact with the paper, which attracts the toner from the drum. The paper is passed through a fuser that is made up of hot rollers, which melts the toner into the paper.
drum head
a bass drum if it is tilted on its side but if it is part of a set of 3, 4, or 5 it is part of the tympani
The part of the seismograph that moves during an earthquake is called the pen.
The bass kick drum in a full drumset utilizes a type of mallet. Tympani drums also use this.
The skin of the drum vibrates to produce sound.
The drum stick... is called the drum stick... What do you mean?
The head of the drum, the part that is struck by drum sticks, vibrates.
The paper rotates on a drum under the pen while the pen moves across the drum.
A drum brake is a brake that uses friction caused by a set of shoes or pads that press against a rotating drum-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum.
Image TransferAll Electrostatic Copiers work under the premis that a charge of electricity is placed on an Image Drum which has the ability to retain the electric charge much like a capacitor holds it's charge but with the ability to hold or release the charge depending on how much light and darkness is applied to the Image Drum. on analog copiers the light and darkness is reflected from the mirrors on the scan area and brought down to the drum surface creating the image that was reflected from the paper that is being scanned. On digital copiers the Image is processed (much like a desktop scanner) by processing the reflected image and converting the image into dots(DPI) then a laser will shoot a light laser image corresponding to the paper that is being scanned onto the Image drum. Image Creation Now that the Image Drum has been hit with light either from the laser or the reflecting light, it will have various charges on its surface (exacting the Image of the scanned original paper) this is called an elecrtostatic latent Image (ESLI) The Image Drum with the ESLI will now be turned till it reaches the developing unit (where toner and developer are mixed to charge the toner (yes toner has the ability to magnetize after mixed with the developer powder) Now, where the drum meets the developer roller is the magical part. Now that the toner is charged with magnetism it will adhire to the Image drum (where the dark electrostatic parts from the Paper Image came down on the Drum) making all the dark parts pull in the toner to the drum and all the light parts do not allow toner to contact the Image Drum, now this Image drum has an image with toner on it (wanna test this ? Stop a copy in the middle of copying, open the copier and pull out the drum, you will see toner on the drum with parts of the image from the original paper ) After the Image on the drum is full of toner It will be turned where the Transfer part is executed Image transferEver put metal fragments on a paper then put a magnet below the paper ? the fragments are attracted to the magnet. This is how the transfer process is done. the drum is turning with the image of toner on it the a paper is positioned below the drum and sinchronized at the same speed with the Image drum, at the point where the paper and the drum meet a high voltage is applied in order to attract the toner off the Image drum and on to the paper, now the paper is full of toner looking like the Image original paper that was scanned. Final sequence now that the Toner is on the paper (looking just like the original) two rollers with heat at about 200 Digrees F press the toner on to the paper making it permanently fused on the paper.
