Abstract
A carrier vapor diluting unit of a liquid printer dilutes and exhausts carrier vapor generated in a fusing apparatus. The unit includes a housing to surround the thermal roller and the pressing roller, a duct which is connected to an inside and an outside of the housing and forms a path through which a mixed gas in which the carrier vapor is mixed with the air is drawn and exhausted, and a fan which forcibly transfers the mixed gas via the duct.
Claims27
A carrier vapor diluting unit of a liquid printer, which dilutes and exhausts carrier vapor generated in a fusing apparatus to fuse an image on paper using heat and pressure while passing the paper between a thermal roller and a pressing roller that are engaged and rotate, the unit comprising:
- a housing to surround the thermal roller and the pressing roller;
- a duct which is connected to an inside and an outside of the housing and forms a path through which a mixed gas in which the carrier vapor is mixed with the air is drawn into and exhausted;
- and
- a fan which forcibly transfers the mixed gas via the duct.
A liquid printer comprising:
- a photosensitive drum on which an electrostatic latent image is formed;
- a developing unit including a developing roller which forms a toner image by supplying a liquid developing agent to the electrostatic latent image;
- a transfer medium which transfers the toner image onto the paper;
- a fusing apparatus which fuses the toner image on the paper using heat and pressure while passing the paper between a thermal roller and a pressing roller that are engaged with each other and rotate;
- and
- a carrier vapor diluting unit which dilutes and exhausts carrier vapor generated in the fusing apparatus, wherein the carrier vapor diluting unit comprises:
- a housing to surround the thermal roller and the pressing roller;
- a duct which is connected to an inside and an outside of the housing and forms a path through which a mixed gas in which the carrier vapor is mixed with the air is drawn and exhausted;
- and
- a fan which forcibly transfers the mixed gas via the duct.
A fusing apparatus housing of a liquid printer, which dilutes and exhausts a carrier vapor generated in a fusing apparatus that fuses an image on paper using heat and pressure, the fusing apparatus housing comprising:
- a ducted housing, surrounding the fusing apparatus, having at least one duct extending from an inside to an outside of the ducted housing and through which a mixed gas is exhausted, the mixed gas comprising the carrier vapor mixed with air.
A liquid printer comprising:
- a photosensitive drum on which an electrostatic latent image is formed;
- a developing unit including a developing roller which forms a toner image by supplying a liquid developing agent to the electrostatic latent image;
- a transfer medium which transfers the toner image onto the paper;
- and
- a fusing apparatus which fuses the toner image on the paper using heat and pressure while passing the paper between a thermal roller and a pressing roller that are engaged with each other and rotate;
- wherein the fusing apparatus comprises a fusing apparatus housing which dilutes and exhausts a carrier vapor generated in the fusing apparatus, the fusing apparatus housing comprising:
- a ducted housing, surrounding the fusing apparatus, having at least one duct extending from an inside to an outside of the ducted housing and through which a mixed gas is exhausted, the mixed gas comprising the carrier vapor mixed with air.
A fusing apparatus that fuses an image on paper using heat and pressure, the fusing apparatus having a carrier vapor diluting unit formed as a single body with the fusing apparatus to dilute and exhaust a carrier vapor generated in the fusing apparatus, wherein the carrier vapor diluting unit has at least one duct extending from an inside to an outside of a housing of the fusing apparatus, through which a mixed gas is exhausted, the mixed gas comprising the carrier vapor mixed with air.
