Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] Such as figure 1 As shown, the printer in this embodiment includes a casing, a paper pick-up mechanism, a paper pickup mechanism 1 , and an imaging device disposed in the casing, and a paper detection sensor disposed at the paper feeding position of the paper pickup mechanism 1 . Wherein, the paper pickup mechanism, the paper pickup mechanism 1, and the imaging device can all adopt corresponding structures in existing printers. The paper feeding process of the printer is usually to first control the paper pickup mechanism to work, and then rub the paper in the paper box to move. When the paper reaches the paper feeding position of the paper pickup mechanism 1, the paper detection sensor is triggered, and then based on the triggering of the paper detection sensor The signal controls the pick-up mechanism 1 to start working in advance, s...

The invention relates to a paper feeding correction method which is characterized in that after printing work is started, actual paper picking time T1 is calculated according to a paper starting point signal and a paper ending point signal which are obtained through detection, and theoretical paper picking time T0 = L / V0 is calculated according to the length L of current paper and the set paper picking speed V0 of a paper picking mechanism; and determining the starting time point of the imaging device during one-time printing work based on the time difference of T1 relative to T0. The paper feed correction method can better and more accurately solve the problem of up-and-down offset of the printed image. The invention further relates to a printer which comprises a machine shell, a paper rubbing mechanism, a paper picking mechanism and an imaging device and further comprises a paper detection sensor arranged at the paper feeding position of the paper picking mechanism, the printer applies the paper feeding correction method, and a paper starting point signal and a paper end point signal are detected through a paper detection sensor. The printer is better in printing effect.
Description
technical field [0001] The invention relates to the technical field of printers, in particular to a paper advance correction method, and also to a printer applying the paper advance correction method. Background technique [0002] Existing printers usually install detection devices upstream and downstream of the paper pick-up mechanism to detect the paper pick-up signal and the trigger signal of the imaging device, and then control the work of the paper pick-up mechanism according to the paper pick-up signal to perform the paper pick-up work. According to the imaging device The trigger signal controls the imaging device downstream of the pick-up mechanism to start working, that is, the paper moves into the paper feeding channel through the action of the pick-up roller. When the paper triggers the detection device upstream of the pick-up mechanism to obtain the pick-up signal, the corresponding control The paper mechanism works to realize the paper picking action. When the p...
