1. Technical Field
The present disclosure relates to printing apparatuses and, particularly, to a printing apparatus using a paper size identifying method
2. Description of Related Art
Printing apparatuses generally print out words or images on paper in accordance with the input data. A paper tray is often used to contain the paper and feed the paper to a printing apparatus along a paper guide, and the paper guide can be adjusted to fit different paper sizes. However, a printing apparatus itself is unable to detect the paper size, and may waste printing consumables when the paper size does not conform to the printing setup, such as printing a small image on an excessively large piece of paper, or vice versa.
Therefore, what is needed is a paper size identifying method for a printing apparatus.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of a paper size identifying method for a printing apparatus. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
The input device 120 includes a paper tray 121, a paper guide 122, a rack member 124, a gear wheel 123, and a detector 125. The paper tray 121 is engageably attached to the main body 110 to feed the paper.
The paper guide 122, including a first adjustor 1221 and a second adjustor 1223 arranged in parallel, can be adjusted to fit the paper on the paper tray 121. The first adjustor 1221 and the second adjustor 1223 moves horizontally on the paper tray 121 to fit both sides of the paper, the paper guide 122 drives a rack member 124 to move. The rack member 124 includes a first rack 1243 and a second rack 1241 respectively connecting perpendicular to the first adjustor 1221 and the second adjustor 1223. The first rack 1243 and the second rack 1241 move simultaneously with the first adjustor 1221 and the second adjustor 1223. The first rack 1243 and the second rack 1241 are arranged in parallel and toothed, the teeth (not shown) on the first rack 1243 and the second rack 1241 mesh with the gear wheel 123 to ensure the first rack 1243 and the second rack 1241 are moving the same distance in opposite directions. As well as ensuring the first adjustor 1221 and the second adjustor 1223 are in unison when being adjusted.
Referring to
By way of example, in
The main body 110 compares the paper size detected with the printer setup set by the user to determine whether they are conformed. The main body 110 reminds the user if the paper size does not conform to the print setup.
Referring to
In step 32, if the paper is on the paper tray 121, the paper guide 122 is adjusted to fit the both sides of the paper, and drives the rack member 124.
In step 33, one of the identifiers on the second rack is detected by the detector 125 to identify the paper size, and the detector 125 transmits the paper size to the main body 110.
In step 34, the main body 110 determines whether the paper size conforms to the print setup.
In step 35, the main body 110 reminds the user if the paper size does not conform to the print setup.
In step 36, the main body 110 proceeds to print on the paper if the paper size conforms to the print setup.
Therefore, the printing device 100 can save printing consumables by detecting different paper sizes and comparing the paper size with the print setup to remind the user when the paper size does not conform to the print setup.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
