[0002] For thermal printing equipment, when using a ribbon, the ribbon is usually wound on the unwinding wheel and the rewinding wheel, and when printing is in progress, the ribbon is pulled from the unwinding wheel and wound on the rewinding wheel , such a form of color roll is easy to loosen during the transmission process, and it is difficult to locate the color blocks on the color roll, which is likely to cause confusion in printing colors, low printing quality, and it is impossible to know the remaining amount of ribbon. Knowing that the ribbon is running out will cause the printing to stop suddenly or the color cannot be printed, which will seriously affect the printing effect

Embodiment 1
[0041] Embodiment one, such as Figure 4 As shown, when only one color block in the color block group is the color block that needs to be printed, taking the color block that needs to be printed as a magenta block as an example, step S3.1 includes the following specific steps:
[0042] S3.1.1. After the signal detected by the optical sensor 5 changes from a high level to a low level, the magenta block is located after rotating the calculated angle according to the diameter of the ribbon 1 and the length from the magenta block.
Embodiment 2
[0043] Embodiment two, such as Figure 5 As shown, when at least two non-adjacent color blocks in the color block group are color blocks that need to be printed, taking the color blocks that need to be printed as yellow blocks and cyan blocks as an example, step S3.2 includes the following specific steps:
[0044] S3.2.1. After the signal detected by the optical sensor 5 changes from a high level to a low level, according to the diameter of the ribbon 1 and the length from the yellow block, after turning the calculated angle, the yellow block is located;
[0045] S3.2.2. After the yellow block is printed, according to the diameter of ribbon 1 and the length between the end position of the yellow block and the starting position of the cyan block, rotate the calculated angle to locate the cyan block;
Embodiment 3
[0046] Embodiment three, such as Figure 6 As shown, when the color blocks in the color block group are all color blocks that need to be printed, step S3.3 includes the following specific steps:
[0047] S3.3.1. After the signal detected by the optical sensor 5 changes from a high level to a low level, according to the diameter of the ribbon 1 and the length from the yellow block, after turning the calculated angle, the yellow block is located;
[0048] S3.3.2. After the yellow block is printed, according to the diameter of the ribbon 1 coil and the length from the magenta block, after turning the calculated angle, the magenta block is located;
[0049] S3.3.3. After the magenta block is printed, according to the diameter of the ribbon 1 roll and the length from the cyan block, rotate the calculated angle to locate the cyan block;
[0050] S3.3.4. After the cyan block is printed, according to the diameter of the ribbon 1 roll and the length from the black block, rotate the ca...

Abstract
The invention relates to the technical field of printer auxiliary devices, and discloses a printer ribbon positioning and allowance detection method and device. The method comprises the following steps: S1, detecting the initial position of each colour block group in a ribbon; S2, according to data detected in the S1, calculating the remaining rolling diameter D; and S3, according to the remaining rolling diameter D and the length l from the initial position of the next to-be-printed colour block to the tail end position of the previous printed colour block, calculating the rotation angle n needed by an unwinding wheel and located from the tail end position of the previous printed colour block to the initial position of the next to-be-printed colour block. The invention further discloses a printer ribbon positioning and allowance detecting device, which comprises an optical sensor and a first coded disc. The invention has the advantages that: the remaining rolling diameter and the remaining colour block group of the ribbon can be detected; the ribbon can be positioned to the required colour block; ribbon positioning and allowance detection are realized; the printing quality is high; and the smooth operation of the printing process is ensured.
