摘要:
A wet type electrophotographic printer having a catalyst oxidation filter (10) therein includes a discharge passage (30) to discharge air inside of a printer body (180) to the outside, a blower (20) in the discharge passage (30) to guide the air inside of the printer body, and a catalyst oxidation filter (10) arranged in the discharge passage (30). The catalyst oxidation filter (10) includes a matrix coated with an oxidation catalyst, to deodorize the air which is guided to the discharge passage as the air is passed therethrough.

An electrophotographic printer is provided. The electrophotographic printer includes: a photosensitive belt (110) capable of moving around a continuous loop by a plurality of rollers (121-123); a main corona device (135) for increasing the electrical charge potential at the surface of the photosensitive belt (110) to a level capable of achieving development; first, second, third and fourth laser scanning units (LSUs) (132, 134, 136, 138) for forming an electrostatic latent image on the photosensitive belt (110) by colour; first, second, third and fourth developing units (142, 144, 146, 148) for individually developing the electrostatic latent image by using first, second, third and fourth developing solutions (143, 145, 147, 149) which have different colours; a drying roller (150) for removing carrier from the developing solution developed on the photosensitive belt by pressing the photosensitive belt (110), which is frictionally charged positively (+) through contact with the photosensitive belt (110); an eraser (134) for removing the electrostatic charge on the electrostatic latent image remaining on the photosensitive belt (110) after the development to uniformly electrify the surface of the photosensitive belt (110) with exposing charge potential; and a charge-increasing electrifying unit (220, 240, 260, 280) for increasing an electrical charge potential at the surface of the photosensitive belt (110), which was lowered while the previous developing, to an electrical charge potential capable of performing another development using a development solution.

摘要:
A paper ejecting apparatus in a video color printer is constructed to push out a completely printed paper for ejecting the paper. The apparatus includes long guide channels (15,16) formed in a panel (2) feeding the paper toward the ejecting direction, a pusher (17) movable along the guide channels, a rack gear member (20) connected to the pusher, a guide support member (21) for movably supporting the rack gear member, and driving means for driving the rack gear member having a pinion driven by a driving source. Also, components are added to the driving means for preventing overload of the driving source. The operation of the apparatus is smooth, so that the paper is securely ejected without being damaged, and the apparatus is simple in structure and causes little mechanical noise.
