Description

Technical Field

[0001] This utility model relates to the field of printer technology, and specifically to a printer that is easy to maintain. Background Technology

[0002] Specifically, in existing printers, during the printing process, paper enters the printing area via the paper feed rollers and then passes through the paper guide channel below the printhead to complete the printing. During this process, due to various reasons such as inconsistent paper quality, humidity changes, wear on the paper feed rollers, or an unreasonable design of the paper guide channel, paper may get stuck in the printhead area. Once a paper jam occurs, the paper cannot pass smoothly through the printhead, causing the printing job to be interrupted.

[0003] Existing solutions typically require users to open the printer casing and carefully remove the jammed paper from the narrow space under the printhead. This process is not only time-consuming but also prone to damaging the printer's internal structure. Especially without specialized tools and experience, improper user operation can damage the printhead or other sensitive components, further increasing repair costs. Utility Model Content

[0035] Reference Figures 1 to 4 A printer that is easy to maintain includes a printhead 1, a printing area 2, a housing 3, a maintenance door 4, an inlet 31, and an outlet 32;

[0036] The inlet 31 is located on one side of the housing 3, and the outlet 32 ​​is located on the other side of the housing 3;

[0037] The printing area 2 is located inside the housing 3, between the inlet 31 and the outlet 32;

[0038] The maintenance door 4 is rotatably mounted on the housing 3 between the inlet 31 and the outlet 32, and the maintenance door 4 is located on one side of the printing area 2.

[0039] Currently, using paper that is too thin, too thick, too soft, too hard, too slippery, too coarse, or too wet can all cause the paper to curl, wrinkle, stick together, or slide poorly inside the printer, resulting in paper jams in the print head area. If a paper jam occurs, maintenance door 4 can be opened to remove or straighten the jammed paper. Furthermore, during printer maintenance, parts such as the print head 1 in the print area can be replaced through maintenance door 4 without disassembling the entire casing, making maintenance simpler and faster compared to existing technologies.

[0040] Reference Figure 1 In one embodiment, the maintenance door 4 includes a frame 41 and a transparent window 42, the frame 41 being rotatably mounted on the housing 3, and the transparent window 42 being fixed on the frame 41.

[0041] Normally, users only discover a paper jam after waiting for a while at the exit 32 or hearing abnormal noises from the printhead 1. However, in this embodiment, by setting a transparent window 42, users can directly observe the inside of the casing 3 through the transparent window 42 and check whether there is a paper jam more intuitively.

[0042] The transparent window 42 is fixed to the frame 41. This design can protect the transparent window 42 from damage. While ensuring that the maintenance door 4 has a transparent observation function, it also enhances the stability of its structure and reduces the risk of the transparent window breaking.

[0043] Specifically, the transparent window 42 is made of glass or resin, and the frame 41 is made of metal or other materials with greater strength than the transparent window 42.

[0044] Reference Figure 2 as well as Figure 4 In one embodiment, a first unobstructed area 51 is provided inside the housing 3 and above the printing area 2, and the maintenance door 4 is located on one side of the first unobstructed area 51. The first unobstructed area 51 allows for easy observation of the printing process inside the printer from the outside through the transparent window 42; and in the event of a paper jam, the user can operate within the first unobstructed area 51 to remove the jammed paper from the print head 1 or replace the print head 1, further improving the convenience of printer maintenance.

[0045] In one embodiment, the printhead 1 is located within the printing area 2 on the side closest to the pivot of the maintenance door 4. In actual use of the printer, space constraints may prevent the maintenance door 4 from being fully opened. In such cases, if the printhead 1 is located away from the pivot of the maintenance door 4, it is inconvenient for the user to observe the printhead 1 or reach out for operation, resulting in difficult operation and potential blind spots. The solution in this embodiment minimizes these issues, making it particularly suitable for printer maintenance in confined spaces.

[0046] In one embodiment, the maintenance door 4 is equipped with a lock. This prevents children from accidentally putting their hands into the printing area 2 and ensures that the components inside the casing 3 have not been replaced by unauthorized personnel, thereby improving the safety of the printer.

[0047] Reference Figure 4 Furthermore, the print head 1 includes an upper print head 11, a lower print head 12, a paper feeding channel 52, a left support plate 61, and a right support plate 62;

[0048] The left support plate 61 and the right support plate 62 are arranged opposite to each other, and the paper feeding channel 52 and the printing area 2 are located between the left support plate 61 and the right support plate 62.

[0049] The upper print head 11 is located in the printing area 2 and above the paper feeding channel 52, and the upper print head 11 is used to print the front side of the paper;

[0050] The lower print head 12 is located in the printing area 2 and below the paper feeding channel 52, and is used to print the reverse side of the paper.

[0051] The simultaneous operation of the upper printhead 11 and the lower printhead 12 can improve the printing efficiency of this printer.

[0052] Specifically, the upper print head 11 is used to print the main text portion of the paper, and the lower print head 12 is used to print the coded portion of the paper.

[0053] Specifically, the right support plate 62 is located on the side close to the maintenance door 4, and a second unobstructed area 53 is provided below the paper feeding channel 52. A slot 621 communicating with the second unobstructed area 53 is provided on the right support plate 62, and the slot 621 is arranged adjacent to the maintenance door 4.

[0054] When the lower printhead 12 malfunctions, the user can reach into the second unobstructed area 53 along the slot 621 to perform maintenance on the lower printhead 12.

[0055] More specifically, it also includes the slide rail 7 and the slide rail fastener 8;

[0056] One end of the slide rail 7 is detachably connected to the left support plate 61, and the other end is detachably connected to the slide rail fixing member 8;

[0057] The print head 1 is slidably mounted on the slide rail 7;

[0058] The slide rail fixing member 8 is detachably connected to the right support plate 62. The slide rail fixing member 8 is used to fix the slide rail 7 on the right support plate 62 and restrict the movement position of the print head 1.

[0059] The slide rail fixing component 8 serves two purposes: firstly, it secures the slide rail 7 to the printer, providing a smooth and directional movement path for the print head 1; secondly, it limits the movement of the print head 1. When the print head 1 is damaged, the maintenance door 4 can be opened, and the slide rail fixing component 8 can be removed from the right support plate 62. Subsequently, the print head 1 can be pulled off the slide rail 7 for separate maintenance, which is convenient and quick.

[0060] Specifically, the slide rail fixing component 8 and the right support plate 62 are connected by conventional detachable connection methods in the prior art, such as screws and buckles.

[0061] Reference Figure 3 More specifically, the slide rail 7 includes an upper slide rail 71 and a lower slide rail 72, the upper print head 11 is slidably disposed on the upper slide rail 71, and the lower print head 12 is slidably disposed on the lower slide rail 72.

[0062] More specifically, the upper slide rail 71 is located within the first unobstructed area 51, and the lower slide rail 72 is located within the second unobstructed area 53. When the upper printhead 11 requires maintenance or experiences a paper jam, the user or maintenance personnel can clear the paper jam or perform maintenance on the upper printhead 11 within the first unobstructed area 51. Similarly, when the lower printhead 12 requires maintenance, the user can perform maintenance on the lower printhead 12 within the second unobstructed area 53.

[0063] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
