Description

Technical Field

[0001] This utility model mainly relates to the field of printer technology, specifically to a printer for restoring old photos. Background Technology

[0002] In the restoration and printing of old photos, high requirements are placed on the printer's resolution, color reproduction and other technical parameters. The printer needs to have a resolution of at least 4800×1200dpi and support Adobe RGB or sRGB wide color gamut. In addition, to obtain better photo printing results, the printhead needs to have a self-cleaning function to avoid ink blockage and short lines that affect the continuity of lines in the photo.

[0003] When inkjet printing is performed using piezoelectric technology on an inkjet board, some ink droplets will spill into the air or adhere to the outside of the inkjet board when ink is ejected from the inkjet nozzles. As the equipment operates for longer periods and due to oversights in the printing process, the inkjet nozzles on the inkjet board can easily become clogged by these adhering ink droplets.

[0004] Currently, cleaning the inkjet plate in a printer typically requires removing it from the printer. However, considering the continuity of equipment operation, the existing truss structure for moving the inkjet plate can be modified and extended. A printing area and a maintenance area can be planned above it, and a scraper structure can be installed. The scraper cleaning component can then be used to scrape away ink droplets from the bottom of the inkjet plate in the maintenance area, preventing excessive ink droplets from adhering to the bottom of the inkjet plate and affecting the subsequent photo printing results.

[0005] This paper proposes a printer for restoring old photos, which improves the inkjet plate drive structure of current printers and adds a cleaning component to prevent ink droplets from clogging the inkjet plate and causing unstable photo printing results. Utility Model Content
