A control method and device for a document feeder of a composite machine

Abstract

The invention relates to the control technology of a compound machine, in particular to a control method and device for a document feeder of the compound machine, a compound machine, and a computer-readable storage medium. The method includes: acquiring a scanned image of the current page of the original after the current page of the original is scanned; performing image recognition on the scanned image to determine whether there is dirt in the scanned image; in response to the presence of dirt in the scanned image, controlling the The document feeder performs dirt detection; in response to the presence of dirt in the document feeder, controlling the document feeder to perform dirt avoidance and reversing the original page of the current page; and controlling after the reversed original page of the current page is scanned The document feeder feeds the next original page. The invention can efficiently detect dirt, and further provides the function of rescanning unqualified scanned images, thereby automatically repairing affected image quality and further improving scanning efficiency in the case of uninterrupted continuous scanning.

Description

technical field [0001] The present invention relates to the control technology of compound machines, in particular to a control method for a document feeder of a compound machine, a control device for a document feeder of a compound machine, a compound machine, and a computer-readable storage medium. Background technique [0002] A multifunction machine uses an automatic document feeder to feed documents for copying or scanning. Please refer to figure 1 , figure 1 A schematic structural view of a conventional automatic document feeder is shown. Such as figure 1 As shown, the original to be scanned is placed on the original tray 21 of the document feeder 2 , the paper passes through the rollers 24 - 26 of the document feeder 2 , and finally falls into the original output tray 23 . When the paper passes through the surface of the front normal-speed conveying glass 11 during the conveying process, the lamp tubes 13 in the lower first moving frame 131 are simultaneously tur...

Problems solved by technology

However, when the fast or omitted setting (using the default setting of the MFP) starts scanning immediately, if the dirt detection is still in progress, the scan can only start after the dirt detection is completed, which affects the scanning efficiency and user experience

[0007] The limitation of post-scanning dirt detection is that for the newly scanned original and the finished task, when the dirt is found to affect the image quality, the current task has to be abandoned, and the parts are cleaned before copying or scanning again

Re-copying will also cause waste of consumables and manpower

The interval between the two scanning tasks is long. Due to the change of the dirt status during the interval, the detection results of the previous task may not be applicable to the subsequent tasks, which will affect the scanning quality of the subsequent tasks.
