Imaging drum
The drum has cylindrical inner and outer sleeves (140,160) supported on a central axle (100). Several fins (146) are provided at constant intervals along the radial direction in the interior surface of the inner sleeve. A cavity is formed between the interior surface of the inner sleeve and the cent...

| description | The drum has cylindrical inner and outer sleeves (140,160) supported on a central axle (100). Several fins (146) are provided at constant intervals along the radial direction in the interior surface of the inner sleeve. A cavity is formed between the interior surface of the inner sleeve and the central axle. The outer sleeve is arranged to receive the inner sleeves in a telescopic manner. Both the sleeves are arranged so that heat is transmitted from one sleeve to the other. The exterior surface (163) of the outer sleeve is coated with a dielectric layer to receive and to retain an electrostatic latent image. The central axle has an air passage (104) in between the two ends of the axle. A fan assembly (170) supplies air at both ends of the axle. The air delivered at the passage is passed to the cavity through the apertures (105) formed in the main body (101) of the axle. A heater (180) heats the air delivered at the passage. A sensor (190) detects the temperature of the outer sleeve and transmits a signal to a controller (200). Based on the received signal, the controller is used to energise the heater selectively so that the temperature of the outer sleeve is maintained between 50-80[deg]. |
