Architecture for an image-forming device
View Patent ↗An image forming device includes a body having a top, a bottom, a front and a back. In one embodiment, a plurality of horizontally-aligned imaging units, each comprising a photoconductive member, transfer toner images to an intermediate transfer mechanism located below the plurality of imaging units. A pick mechanism may pick media sheets from a media input tray and feeds the media towards the front of the body. For duplex printing, the media sheets may travel along a duplex path that extends along the front of the body. In one embodiment, an access door at the front of the body pivots between a closed position and an open position. In the open position, a user may gain access to both media paths.
1. An image-forming device comprising:
a body having a front, a back, a bottom, and a top;
a media input tray located at the bottom of the body;
a control panel positioned on the front of the body;
a plurality of imaging units aligned along a horizontal plane extending from the front of the body to the back of the body;
a plurality of toner reservoirs each removably connected to one of the plurality of imaging units, each of the plurality of toner reservoirs being removable from the body through the top;
an intermediate transfer mechanism located between the media input tray and the plurality of imaging units to receive toner from the imaging unit and move the toner to a second transfer area;
a first power supply located between the intermediate transfer mechanism and the media input tray; and
a support frame including a first support member, the first support member being rigid to support the body and extending substantially around the first power supply to electrically shield the first power supply from an interior of the body.
2. The device of claim 1 wherein first power supply is further located at the back of the body proximate a pick mechanism that is configured to feed media sheets from the media input tray towards the front of the body.
3. The device of claim 1 further comprising a second power supply and a second support member, the second support member being rigid to support the body and extending substantially around the second power supply to electrically shield the second power supply.
4. The device of claim 3 further comprising a fusing mechanism disposed at the front of the body to fuse the toner to the media sheets, and wherein the second power supply is located proximate the fusing mechanism.
5. The device of claim 4 further comprising controller circuitry and a third support member located between the plurality of imaging units and the back of the body, the third support member being rigid to support the body and extending substantially around the controller circuitry to electrically shield the controller circuitry.
6. The device of claim 1 further comprising a substantial C-shaped media path including a substantially vertical section that extends between the front of the body and the intermediate transfer mechanism, and is closer to the front of the body than each of the plurality of imaging units.
7. An imaging apparatus, comprising:
a body having a front, a back, a bottom, and a top;
a media input tray located at the bottom of the body;
a plurality of imaging units aligned along a substantially horizontal plane extending from the front of the body to the back of the body;
a plurality of toner reservoirs each removably connected to one of the plurality of imaging units, each of the plurality of toner reservoirs being removable from the body;
an intermediate transfer mechanism located between the media input tray and the plurality of imaging units to receive toner from the imaging unit and move the toner to a second transfer area;
a first power supply located between the intermediate transfer mechanism and the media input tray; and
controller circuitry and a first support member located between the plurality of imaging units and the back of the body, the first support member being rigid to support the body and extending substantially around the controller circuitry to electrically shield the controller circuitry.
8. The device of claim 7 further comprising a substantial C-shaped media path including a substantially vertical section that extends between the front of the body and the intermediate transfer mechanism, and is closer to the front of the body than each of the plurality of imaging units.
9. The device of claim 7 wherein the first power supply is further located at the back of the body proximate a pick mechanism that is configured to feed media sheets from the media input tray towards the front of the body.
10. An imaging apparatus, comprising:
a body having a front, a back, a bottom, and a top;
a media input tray located at the bottom of the body;
a plurality of imaging units aliened along a substantially horizontal plane extending from the front of the body to the back of the body;
a plurality of toner reservoirs each removably connected to one of the plurality of imaging units, each of the plurality of toner reservoirs being removable from the body;
an intermediate transfer mechanism located between the media input tray and the plurality of imaging units to receive toner from the imaging unit and move the toner to a second transfer area;
a first power supply located between the intermediate transfer mechanism and the media input tray; and
a support frame including a first support member, the first support member being rigid to support the body and extending substantially around the first power supply to electrically shield the first power supply from an interior of the body.
11. The device of claim 10 further comprising a second power supply and a second support member, the second support member being rigid to support the body and extending substantially around the second power supply to electrically shield the second power supply.
12. The device of claim 11 further comprising a fusing mechanism disposed at the front of the body to fuse the toner to the media sheets, and wherein the second power supply is located proximate the fusing mechanism.
13. The device of claim 10 , further comprising controller circuitry and a second support member located between the plurality of imaging units and the back of the body, the second support member being rigid to support the body and extending substantially around the controller circuitry to electrically shield the controller circuitry.
