Problems solved by technology

[0003] However, in some technologies, the color of the consumable support and the color of the printing medium need to be designed as a color with a large contrast. For example, when the printing medium is white, the color of the consumable support needs to be set to black, so that the electrical signal output by the optical sensor has a higher The degree of distinction, which leads to a narrow range of color options for the consumables bracket, and even cannot be consistent with the overall appearance of the printer, which affects the appearance of the printer

Abstract

The present application provides a printer and a printing medium sensing method. The printer includes a consumables holder, a sensing device, and a controller. The consumable support is used to support the printing medium; the consumable support is at least partially arranged in the sensing area of ​​the sensing device, and the sensing device is used for sensing the color in the sensing area and outputting a digital signal corresponding to the color; the controller and the The sensing device is connected to receive a digital signal. If the value of the digital signal is within the first numerical range, it is determined that there is a printing medium on the consumables support; if the value of the digital signal is within the second numerical range, it is determined that there is no printing medium on the consumables support . The appearance color of the printer and the color of the consumable holder can be close to or consistent, which improves the appearance of the printer.

Description

technical field [0001] The present application relates to the field of printing technology, and in particular, to a printer and a printing medium sensing method. Background technique [0002] When a printer is printing, it is usually necessary to sense whether there is a printing medium (eg, printing paper) in the printer. Some techniques are to design the color of the consumable holder supporting the printing medium to be a different color from that of the printing medium, and to set an optical sensor on the printer, so that when there is printing medium, the optical sensor senses the color of the printing medium, and when there is no printing medium, the optical sensor senses the color of the printing medium. When media is loaded, the optical sensor senses the color of the filament holder. The optical sensor generates an electrical signal corresponding to the color, so that the printer can judge whether there is a printing medium in the printer according to the electrical...
