Abstract

A base device to support a finisher includes a base pan, a first plurality of casters coupled to the base pan, a second plurality of casters coupled to the base pan, and a recess to receive a tip foot. The base pan includes a section which protrudes outward from a first side of the base pan. The first plurality of casters are coupled to the base pan to contact a surface when the base pan is level with respect to the surface, each of the first plurality of casters being beside a respective separate corner of the base pan and at least two of the first plurality of casters being beside the section. The second plurality of casters are to be positioned above the surface when the base pan is level with respect to the surface and to contact the surface when the base pan is inclined to a threshold.

First claim

What is claimed is:

1. A base device to support a finisher comprising:
a base pan including a section being in a form of a protrusion which protrudes outward from a first side of the base pan;
a first plurality of casters coupled to the base pan to contact a surface while the base pan is level with respect to the surface, each of the first plurality of casters being beside a respective separate corner of the base pan and at least two of the first plurality of casters being beside the protrusion as the section of the base pan;
a second plurality of casters coupled to the protrusion as the section of the base pan, to be positioned above the surface while the base pan is level with respect to the surface and to contact the surface while the base pan is inclined to a first degree of tilt with respect to the surface, each of the second plurality of casters having a diameter smaller than a diameter of each of the first plurality of casters; and
a recess, between at least two of the second plurality of casters, to receive a tip foot, the tip foot arranged to:
contact the surface while the base pan is inclined to a second degree of tilt with respect to the surface, the second degree of tilt being different than the first degree of tilt; and
be positioned above the surface while the base pan is, with respect to the surface, level or inclined below the second degree of tilt.

2. The base device of claim 1 , wherein the recess is coupled to a bottom-side of the base pan.

3. The base device of claim 1 , wherein a number of the first plurality of casters is four.

4. The base device of claim 1 , wherein a number of the second plurality of casters is two.

5. The base device of claim 1 , wherein the first side of the base pan is located below a side of the finisher that receives media output from a printer.

6. The base device of claim 5 , wherein a second side of the base pan is located below a side of the finisher that outputs media to a first output bin and a second output bin.

7. The base device of claim 1 , wherein the first plurality of casters are adjustable and the second plurality of casters are non-adjustable.

8. The base device of claim 1 , wherein the first degree of tilt is a first threshold amount of inclination of the base pan and is based on the diameter of the second plurality of casters.

9. The base device of claim 1 , wherein the tip foot:
is removeable from the recess of the base pan; and
includes a first end arranged to be inserted into the recess and a second end arranged to extend outward from a perimeter of the base pan.

10. The base device of claim 9 , wherein the second degree of tilt is a second threshold of inclination of the base pan and is based on the distance the tip foot is above the surface and the distance the second end of the tip foot extends outward from the perimeter of the base pan.

11. A finisher comprising:
a body;
an input section, on a first side of the body, to receive recording medium from an image forming apparatus;
a finishing section to perform a finishing operation on the received recording medium;
an output section, on a second side of the body and opposite the first side, to output the finished recording medium to an output bin;
a first plurality of casters coupled to a bottom of the body to contact a surface while the bottom of the body is level with respect to the surface, each of the first plurality of casters being beside a respective separate corner of the bottom of the body and at least two of the first plurality of casters being beside an extending section of the bottom of the body being in a form of a protrusion which protrudes outward from the first side of the body;
a second plurality of casters coupled to the protrusion being the extending section of the bottom of the body, to be positioned above the surface while the bottom of the body is level with respect to the surface and to contact the surface while the bottom of the body is inclined to a first degree of tilt with respect to the surface, each of the second plurality of casters having a diameter smaller than a diameter of each of the first plurality of casters; and
a recess, between at least two of the second plurality of casters, to receive a tip foot, the tip foot arranged to:
contact the surface while the base pan is inclined to a second degree of tilt with respect to the surface, the second degree of tilt being different than the first degree of tilt; and
be positioned above the surface while the base pan is, with respect to the surface, level or inclined below the second degree of tilt.

12. The finisher of claim 11 , wherein the finisher further includes a sensor to sense a presence of an output bin or finished recoding medium in the output bin.

13. The finisher of claim 12 , wherein the finisher further includes a controller, wherein when the sensor senses the output bin or the finished recording medium in the output bin, the controller determines the amount of finished recoding medium in the output bin is above a threshold.

14. The finisher of claim 13 , wherein when an amount of the finished recording medium in the output bin is above the threshold, the controller instructs a control panel to display an image to remove at least some of the finished recording medium from the output bin.

15. The finisher of claim 12 , wherein the sensor is on the second side of the body.

16. The finisher of claim 11 , wherein the recess is coupled to the bottom of the body.

17. The finisher of claim 11 , wherein the first plurality of casters are adjustable and the second plurality of casters are non-adjustable.

18. The finisher of claim 11 , wherein a number of the second plurality of casters is two.
