Definitions
- Print module with front replaceable printhead
- the present invention relates to a print module with front replaceable printhead in an ink jet printer.
- Inkjet printers typically include a printing module and positioning means adapted to be able to move the printing module and a medium having a surface to be printed in a predetermined manner at a constant distance of the printing module from the surface in two dimensions relative to one another.
- the printing module itself has at least one print head with at least one nozzle row of juxtaposed nozzles, via which ink can be applied to the surface to be printed.
- the printing takes place by the ejection of ink drops according to a predetermined optionally variable pressure frequency and number of drops. Scanning printers and single-pass printers are known in the art.
- a scanning printing module travels in one or more passports across a line of media to be printed, during which time that line is printed.
- the corresponding method is called scanning method. If a line is printed in a scanning process, then the medium to be printed is moved by one line perpendicular to the scanning direction executed by the print head in a feed direction and the printing of the next line can begin.
- a printer is understood to comprise a printing module with at least one print head stationarily positioned over the medium to be printed, the medium being continuously moved in an operating mode and the at least one print head being moved in the corresponding single-pass method sees the medium once, with the printhead itself being stationarily mounted on the printing module.
- a printing module comprises known on the front side a carrier, which is designed as a frame with at least one opening which is provided for receiving a printhead and on which frame the mounting of the printhead takes place, wherein in the known printing modules of the frame the printhead only from the Top of the print module, so only on the back, can receive.
- On the frame itself adjusting devices are provided with which the print head can be aligned.
- a variety of electronic and mechanical components are provided on the frame and over the printhead for proper operation of the printhead.
- printing modules In order to meet the increased demands of space saving, printing modules have been built increasingly compact. The advantage here is that in addition to the space savings in addition material costs can be saved.
- a problem causing the slow replacement of the print heads is thus the fact that in the printing modules known today, only the above-described construction concept for the reception of the print head is realized. There is therefore a need for a printing module and method that can quickly and efficiently accomplish the replacement of a printhead on a printing module, despite limited accessibility from the top.
- the present invention is therefore an object of the invention to provide a printing module and a method with which despite limited accessibility from the top, at any time a rapidly feasible replacement is guaranteed in case of repair.
- front side of the printing module refers to the side of the printing module which looks directly onto a storage device for a medium to be printed.
- front-side received this refers to a front-side introduction of the printhead into the carrier.
- a printing module comprising a front-mounted assembly for mounting a printhead in an ink-jet printer, the printing module being spaced relative to a tray, and the assembly comprising a support frame having an opening extending through the support frame and for the printer Recording / delivery of the printhead is provided characterized in that the assembly comprises means for mounting the printhead, which allow a front-side receiving the same in a repair position of the printing module relative to the storage device. Repair position may mean that the distance between the printing module and the storage device has been increased in order to allow front removal. However, other variants are conceivable, such as storage of the print head on an applied to the filing support. To insert or remove the printhead (s), only the remainder of the printing module will be approximated or removed.
