Master controller issues signal to printer control chip at this time, and printer controls the operating of chip drives chart drive motor, toward printer
Interior paper feed；
When the voltage signal for thering is at least two photoelectric sensor to detect in N2 photoelectric sensor for being located at printer
When greater than corresponding threshold voltage, then judge that paper does not glance off, when only 1 photoelectric sensor in N2 photoelectric sensor
When the voltage signal detected is greater than corresponding threshold voltage, then judge that paper glances off, master controller is to printer at this time
It controls chip and issues signal, printer control chip controls chart drive motor shuts down, while master controller starting correction motor
Operating adjusts paper posture, when detecting that voltage that at least two photoelectric sensor detects is greater than corresponding threshold value electricity again
After pressure, it is believed that rectify a deviation successfully, master controller stops correction motor operating, while sending a signal to printer main control chip, prints
Machine main control chip restarts chart drive motor.
Further, the calculation formula of the corresponding threshold voltage of photoelectric sensor is as follows:
In above formula, VTHIt (i) is the corresponding threshold voltage of i-th of photoelectric sensor, VijFor i-th of photoelectric sensor jth time
Sampled voltage, i=1,2 ..., N, VREFFor reference voltage, for guaranteeing the threshold voltage of setting slightly larger than examining under no paper-like state
The voltage measured.
Further, in step (1), if m=8, i.e., 8 voltage signals are sampled to each photoelectric sensor and sought averagely
Value.
By adopting the above technical scheme bring the utility model has the advantages that
The present invention carries out multiple spot detection using multiple sensors, and each sensor has one's own threshold voltage, and
And the setting of each sensor threshold threshold voltage is obtained using the method that multiple repairing weld is averaged, and can be made up so previous single
Deficiency existing for threshold voltage method.Precision of the invention is high, and rectifying effect is good, and practical application is strong.
Detailed description of the invention
Fig. 1 is the system composition block diagram of the invention.
Fig. 2 is flow chart of the method for the present invention.
Specific embodiment
Below with reference to attached drawing, technical solution of the present invention is described in detail.
A kind of printer paper deviation-rectifying system, as shown in Figure 1, including master controller and the correction being attached thereto respectively electricity
Machine, memory and 12 photoelectric sensors, 4 photoelectric sensors therein setting is in printer paper inlet, and remaining 8
Photoelectric sensor is arranged in printer.Master controller is connected with printer control chip and carries out data interaction, memory
The corresponding threshold voltage of each photoelectric sensor is stored, when printer work, master controller adopts each photoelectric sensor
The threshold voltage that the voltage signal of collection is corresponding is compared, thus judge paper whether deflection, when paper glances off,
Master controller driving correction motor operating, adjusts paper posture, completes paper correction.
The invention also provides the method for correcting error based on above-mentioned deviation-rectifying system, as shown in Figure 2, the specific steps are as follows:
Step 1: printer carries out the setting of photoelectric sensor threshold voltage under the conditions of not filling paper:
Step 11, in order to easy to operate, shortcut key processing has been done to printer in advance；
Step 12, after pressing the shortcut key on printer, printer control chip can detect this movement, at this time will
FWSIG signal (FLASH Write Signal) drags down 2 seconds.
Step 13, master controller, which detects, low pulse signal on FWSIG signal, start photoelectric sensor voltage detecting；
Step 14,12 photoelectric sensors sample 8 times respectively, respectively averaged, in order to reduce the erroneous judgement of sensor,
The voltage value that detects under no paper-like state of ratio sensor for needing for threshold voltage to be arranged is slightly larger, and therefore, it is necessary to acquire
Increase a voltage V on average valueREF, the setting of the voltage is related according to print media, can voluntarily adjust.Assuming that i is photoelectricity
The number of sensor, j are the sampling number of sensor voltage value, VijFor the i-th photoelectric sensor jth time sampled voltage, then i-th

Buzzer sounding can be driven after measuring the signal, the threshold voltage settings of sensor is prompted to complete.
Step 2: detecting voltage with threshold voltage comparison according to sensor to judge whether paper is put when being put into paper
It is oblique:
Step 21, when being sent into paper toward printer, if being located in 4 photoelectric sensors of printer paper inlet has
When the voltage that at least one photoelectric sensor detects is greater than the photoelectric sensor corresponding threshold voltage, then it is assumed that detect
Paper, master controller drags down PE signal at this time, and when printer control chip detects that PE is low, driving chart drive motor operating is past
Paper feed in printer；
Step 22, when the electricity for thering is at least two photoelectric sensor to detect in 8 photoelectric sensors for being located at printer
When signal being pressed to be greater than corresponding threshold voltage, then judge that paper does not glance off, when only 1 photoelectricity in 8 photoelectric sensors
