In the same way, in the process of returning and resetting the lottery paper, after the 10-control unit controls the 8-stepping motor to empty and return the paper by L3 distance, the black mark returns to the original position, the state of the black mark sensor1 changes again, if the AD sampling value is lower than the threshold value, no paper sticking occurs, otherwise, the paper sticking occurs, the 10-control unit sets a paper sticking mark and gives an alarm through the 11-audible and visual alarm module.
In one embodiment, when the thermal paper and the heating head piece are adhered, the thermal paper can be detected, and an alarm, an error record and an error report can be generated. And alarming through an 11-sound and light alarming module. Error recording is achieved by setting a variable StickState in the MCU to true. Before each bill is printed, after the printing is finished, the upper computer respectively sends a command for inquiring the state of the printer once, when the sticky paper mark is set, the bill is printed invalidity and reported to the server, and after the server judges that the printing produces the waste bill, the printing command is sent again until the normal lottery bill is printed out, so that a closed loop is formed.
In one embodiment, a technical scheme one for reducing sticking paper is provided, after the lottery ticket face sheet data is printed, the time T of millisecond level is increased, and the method is realized by adding the blank paper feeding and applying the heat dissipation air flow, wherein T is as short as possible, so that the heat generated by the heat-sensitive heating plate in the printing process can be radiated as soon as possible through the blank paper feeding, and the heat is prevented from being intensively released to a certain fixed position with the heat-sensitive paper, and sticking paper is generated. After printing the lottery ticket, the paper is continuously fed forward by a fixed distance L3 in figure 2 through controlling the stepping motor, in the paper feeding process, the air knife applies heat dissipation air flow between the rubber roller and the thermal paper to quicken the heat dissipation of the heating plate, in the whole process, the black mark sensor1 detects the accuracy of paper feeding, and when the paper feeding is inaccurate, the control unit sets a paper sticking mark and triggers audible and visual alarm.

When no paper sticking occurs, the 10-control unit controls the 8-stepping motor to empty and withdraw the paper by L3 distance, the black mark returns to the original position, the state of the black mark sensor1 changes again, if the AD sampling value is lower than the threshold value, no paper sticking occurs, otherwise, paper sticking occurs, the 10-control unit sets a paper sticking mark and gives an alarm through the 11-audible and visual alarm module.
According to the second technical scheme for reducing the sticking of paper, the printer is powered on and turned on and breaks loose once every t time in an idle state. The operation procedure of the first technical scheme is repeated every interval t.
The technical scheme III for reducing the sticking paper is that after the sticking paper occurs, the stepping motor increases the torsion through reducing the speed, simultaneously applies an air knife to break loose, after the break loose is successful, the thermal paper is reset to the initial position through the black mark positioning, and the control unit clears the sticking paper mark.
In the scheme of detecting the sticking state in the printing process, in the step-in and step-out number of a specified stepping motor, the two black mark sensors detect the black mark in the specified step-in number and consider that no sticking occurs, otherwise, the sticking occurs, and the control unit sets a sticking mark.
When the lottery ticket is not adhered to the thermal head, after the normal paper feeding L3, the sensor1 can detect the black label of the lottery ticket, after the normal paper feeding L5-L4, the sensor2 can detect the black label of the lottery ticket, if the lottery ticket is slightly adhered, the thermal paper starts to feed after the stepping motor rotates for a period of time, the paper feeding step number length of the printer can be larger than L3 or L5-L4, and the compression degree of the ticket surface can be calculated according to the difference value.
And reporting the sticky paper, before each bill printing, after finishing printing, the upper computer respectively transmits a printer state inquiring instruction once, when the sticky paper mark is set, the bill printing is invalid and the server is reported, and after the server judges that the printing generates the waste bill, the printing instruction is retransmitted until a normal lottery bill is printed out, so that a closed loop is formed, and as shown in figure 4, the printer, the upper computer and the remote server form a closed loop control circuit.

The black mark sensor1 for detecting whether the sticking occurs or not can also be placed near the paper outlet, as shown in fig. 5, 12-the position of the non-single sensor is located. The 12-non-single sensor can also be used for detecting whether the sticking occurs, and the same control logic can be achieved by using the AD sampling value of the 12-non-single sensor instead of the AD sampling value of the black mark sensor 1.
And (5) starting up a ticket sticking detection flow. After the printer is started and self-checking is finished, firstly executing paper feeding operation, using Sensor1 to detect a black mark in the paper feeding process, if the black mark length of the paper feeding L3 still cannot be detected, sounding a buzzer, setting a state to be a paper sticking error, setting a variable StickState in an MCU to true, and detecting the paper sticking error when an upper computer sends a command to read the state.
After the detection is successful, the lottery paper is returned, the returning distance L3 is reserved, after the returning is finished, whether the Sensor1 detects that the black mark of the lottery ticket leaves the detection range of the Sensor1 is detected, if the black mark leaves the detection return is not detected, the buzzer sounds, the setting state is a paper sticking error, the variable StickState in the MCU is set to true, and the upper computer can detect the paper sticking error when sending a command reading state.
When the paper is cut, the printer is in an idle state, and the printer starts to time t2 in the idle state;
when t2> t1, executing a paper feeding instruction, feeding a paper distance L3, detecting a black mark by a sensor1 after paper feeding is completed, if detection fails, setting a state to be a paper jam error, setting a variable StickState in the MCU to be true, and ringing by a buzzer. If the detection is successful, the jam error state is cleared, and the variable StickState is set to false.
Ticket sticking detection flow during lottery printing
After the paper sticking error is detected by using the state detection function before printing starts, the upper machine interrupts the sales of the lottery ticket, and the transaction is not submitted to the background database, so that the occurrence of incomplete ticket is avoided, and the loss of a lottery ticket operator is reduced.
When the upper computer needs to print, detecting the state of the printer:
if the printer is in a ticket sticking error or other errors, directly returning an error, and not executing subsequent detection; otherwise, sending a printing instruction to print the lottery ticket.
When the lottery ticket is not adhered to the thermal head, after the paper is normally fed by L5-L4, the sensor2 can detect the black mark of the lottery ticket, if the lottery ticket is slightly adhered, the thermal paper starts to be fed after the stepping motor rotates for a period of time, the number of paper feeding steps of the printer is greater than L5-L4, and the compression degree of the ticket surface can be calculated according to the difference value.
A. When printing is started, the printing length count value length is cleared, and the lottery black label is located between the positions Sensor1Pos and Sensor2 Pos.
B. And 1 is added to 1 dot line length per paper feeding, meanwhile, the sensor2 detects the black mark of the lottery ticket, and the length counting is stopped when the black mark is detected.
C. When cutting is completed, the count value length is read, and whether print compression exists is judged.
If |length- (L5-L4) | <8, the paper feeding is normal, and the error is within the allowable range.
If |length- (L5-L4) | >8& (length- (L5-L4)) <24, it is explained that the first line character is compressed.
If (length- (L5-L4)) <24& (length- (L5-L4)) <8 x 50, it is stated that the ticket header is compressed and part of the content is lost.
If (length- (L5-L4)) > 8.times.50, this indicates that the face compression is severe.
When the ticket sticking problem cannot be automatically repaired, the error state needs to be cleared through the modes of uncovering, paper pulling and covering.
The black mark sensor1 for detecting whether or not paper sticking has occurred is characterized in that the black mark sensor1 for detecting whether or not paper sticking has occurred may be placed near the paper outlet or multiplexed with a non-taken single sensor, and the state change of the black mark may be replaced by a change in detecting the presence or absence of paper.
