Abstract

An assembly of a large format media handling system, including a planar longitudinal cross structure; and a support structure, the support structure including two side supports comprising a number of fixed references and at least one adjustable reference, wherein the side supports are supported by the longitudinal cross structure at said references; wherein the at least one adjustable reference is formed by a wedge element slidably attached to the support structure; and the side supports are fixed to the planar longitudinal cross structure wherein the cross structure is in contact with all of the references.

First claim

The invention claimed is:

1. A method of providing an assembly of a media handling system, the assembly including a planar longitudinal cross structure and a support structure, the support structure comprising at least three fixed references and at least one adjustable reference disposed among two side supports of the support structure, the method comprising:
positioning the cross structure relative to the side supports of the support structure, whereby the cross structure contacts the at least three fixed references on the side supports;
adjusting the at least one adjustable reference while the cross structure contacts the at least three fixed references, whereby the cross structure also contacts the at least one adjustable reference on the side supports; and
fixing the planar longitudinal cross structure to the side supports.

2. The method of claim 1 , wherein positioning the cross structure relative to the side supports comprises:
positioning the cross structure relative to the side supports whereby the cross structure contacts three of the fixed references on the side supports; and
applying a compression force to the cross structure to also contact a fourth fixed reference on the side supports,
wherein two fixed reference points are located on a first one of the side supports and two fixed reference points are located on the other one of the side supports.

3. The method of claim 2 , wherein adjusting the at least one adjustable reference comprises adjusting two adjustable references located on the first one of the side supports and two adjustable references located on the other one of the side supports, whereby the cross structure contacts all four adjustable references.

4. The method of claim 2 , further comprising closing an open longitudinal side of the cross structure after fixing the cross structure to the side support so as to form a closed shaped cross section,
wherein the cross structure is initially open along the longitudinal side when positioning the cross structure relative to the side supports and applying the compression force.

5. The method of claim 1 , wherein adjusting the at least one adjustable reference comprises moving a wedge which is slidably attached to the support structure.

6. The method of claim 1 , wherein positioning the cross structure relative to the side supports of the support structure comprises:
vertically positioning the side supports in a positioning tool, each side support having two fixed inner contact lines and two adjustable outer contact lines;
positioning the cross structure on the side supports thereby contacting the at least three fixed references; and
applying a holding force to the cross structure so that the cross structure contacts a fourth fixed reference, the three fixed references and the fourth fixed reference providing the fixed inner contact lines; and
adjusting the at least one adjustable reference comprises:
moving four wedge structures, which are attached to the side supports, relative to the side supports to bring them into contact with the cross structure, each wedge structure providing one adjustable outer contact line, wherein after fixing the cross structure to the side supports, there is contact between the cross structure and the side supports along the fixed inner contact lines and the adjustable outer contact lines.

7. The method of claim 6 , further comprising: turning the assembly of the cross structure and the support structure upside down after having been fixed to each other to provide a base plate and side plates of a large format printer.

8. An assembly of a large format media handling system, including:
a planar longitudinal cross structure; and
a support structure, the support structure comprising a number of fixed references and at least one adjustable reference disposed among two side supports of the support structure, wherein the side supports are supported by the longitudinal cross structure at the number of fixed references and the at least one adjustable reference,
wherein the side supports are fixed to the planar longitudinal cross structure such that the cross structure is in contact with all of the fixed references and the at least one adjustable reference, and
wherein the cross structure is a mounting base plate of a large format printer and the side supports comprise side plates to support substructures of a large format printer.

9. The assembly of claim 8 , wherein the side supports comprise at least four fixed reference points, and wherein the cross structure allows for torsional movement during assembly to contact said at least four fixed reference points.

10. The assembly of claim 9 , wherein:
the cross structure has a generally closed shaped cross section; and
a longitudinal side of the cross structure is open when fixing the side supports to the cross structure, and is closed after the side supports have been fixed to the cross structure.

11. The assembly of claim 8 , wherein at least four wedges are slidably attached to the side supports, the four wedges to provide four adjustable reference points.

12. The assembly of claim 8 , wherein eight contact lines are provided by four fixed references and four adjustable references between the cross structure and the support structure.

13. A large format printer, including:
a planar longitudinal base plate; and
two side plates, each of the two side plates comprising two fixed references and two adjustable references, wherein the side plates are supported by the longitudinal base plate at said references; and
wherein:
the adjustable references are formed by wedge elements slidably attached to the side plates; and
the side plates are fixed to the longitudinal base plate in contact with all of the references.

14. The large format printer of claim 13 , wherein the side plates support printer substructures including at least one of: a print platen, a print head assembly, a print media transport system, a print media holder, a print media input section, and a print media output section, the printer substructures being aligned horizontally by said side plates without inducing any distortion between them or without inducing any elastoplastic deformation between them.
