2. After the double-sided printing photographic paper 2 is arranged below the second press roller 5, the second press roller 5 is enabled to feed forward, the paper feeding distance is preset, after the paper feeding is finished, the printing of photos is started while the forward paper feeding is carried out, so that the position where the printing is started is ensured to be constant from the edge of the front end of the double-sided printing photographic paper 2, after the printing of each photo is finished, a control program reserves a distance of a non-printing pattern at the rear edge of the previous photo, the reserved distance is required to be consistent with the length of a pattern at the edge of a searched photo printed when the second side is printed later, namely, a piece of white paper with a certain length is reserved between the previous photo and the next photo, in the printing process, when the front end of the double-sided printing photographic paper 2 reaches the second sensor 10, the third press roller 9 is pressed down, the bridging turnover plate 12 is synchronously put down, and the photo printed again at this time is pressed down by the self weight of the counter weight, the counterweight pressing roller 8 can stop moving when moving to the side of the third sensor 13, when the length of the buffered double-sided printing photographic paper 2 reaches the position of the third sensor 13, the instruction step number of a certain step number of forward paper feeding of the third pressing roller 9 is preset according to the size of the buffer component, the third pressing roller 9 stops after the preset step number is finished, then the forward paper feeding is continuously printed, the circulation is carried out when the third sensor 13 detects that paper exists, the third pressing roller 9 feeds the paper again for a certain step number, so that the printing of all the photos in an order is finished all at one time, after all the photos are printed on the first side, an 'end' mark is printed at the tail end of the double-sided printing photographic paper 2, then the second pressing roller 5 is lifted, the third pressing roller 9 feeds the paper for a fixed step number, the photos and the tail mark printed on the first side are all moved to the position of the cutter 11, cutting paper, cutting a long strip of double-sided printing photographic paper 2 with the printed first side from the roll paper, then sending out a first press roller 3 to press down, lifting a second press roller 5 and a third press roller 9, taking the roll paper back to a roll paper shaft 1 by the first press roller 3, lifting the first press roller 3, and finishing the printing of the first side.
Printing on the second side:
1. the double-sided printing photographic paper 2 with the printed first side is taken back to a paper inlet of a printer, the non-printed side faces upwards, one end without an end mark is placed below a first compression roller 3, the first compression roller 3 is pressed down, a second compression roller 5 is lifted up, a third compression roller 9 is lifted up, then the first compression roller 3 is used for feeding the paper forwards, when a photographic paper head reaches the position of a first sensor 4, a control program starts to calculate the paper feeding step number of a motor of the first compression roller 3, after the preset step number is reached, the preset value is determined according to the distance from the first compression roller 3 to the second compression roller 5, the double-sided printing photographic paper 2 is ensured to reach the position below the second compression roller 5, the second compression roller 5 is pressed down, after the second compression roller 5 is pressed, the first compression roller 3 is lifted up, and the position of the first sensor 4 is fixed, so that the position of paper feeding is fixed.
2. After the double-sided printing photographic paper 2 is arranged below the second compression roller 5, the second compression roller 5 is enabled to feed forward, the paper feeding distance is preset, after the paper feeding is finished, the photo is printed while the paper is fed forward, so that the position where the printing is started is kept constant from the edge of the front end of the photographic paper, after the printing of each photo is finished, the lower side of each photo is different from the process of printing the first side, a fixed-length specific pattern for searching the edge of the photo is printed behind the previous photo, the length of the specific pattern is consistent with the length of white paper left between the two photos when the first side is printed, in the printing process, when the front end of the double-sided printing photographic paper 2 reaches the second sensor 10, an instruction for pressing down by the third compression roller 9 is enabled, the bridge turnover plate 12 is synchronously put down, the photo printed again at this time can be pressed down by the self weight of the counterweight compression roller 8, and when the length of the buffered double-sided printing photographic paper 2 reaches, at this time, a certain number of steps of forward paper feeding of the third press roller 9 is preset according to the size of the buffer assembly, the third press roller 9 stops after the preset number of steps is finished, the second sensor 10 continuously detects whether a specific boundary pattern exists in the paper feeding process of the third press roller 9, if so, the paper cutter 11 cuts the picture separately, two cutters are cut for each time of cutting the picture, one cutter is arranged in front of the specific pattern, the other cutter is arranged behind the specific pattern, and the specific pattern cannot be left on the previous picture or the next picture. Meanwhile, paper is continuously printed and fed forward, the above circulation is started when the third sensor 13 detects that paper exists, the third press roller 9 is enabled to feed paper again for a certain number of steps, paper is cut again when a specific boundary pattern exists, so that all the photos in an order can be printed at one time, then the second press roller 5 is enabled to lift up, the third press roller 9 feeds paper for a fixed number of steps, all the photos printed on the second surface are taken out of the cutter position, the paper cutter 11 cuts paper when the boundary pattern exists in the middle, the printing on the second surface is finished, and the process of printing the double-sided photos on the double-sided printing photographic paper 2 is finished.
The technical scheme includes that photos are printed on the front side of rolled double-sided printing photographic paper 2, the position of the double-sided printing photographic paper 2 is detected through a paper inlet sensor, the position where the first photo starts to be printed is obtained through operation, paper heads with fixed lengths are reserved, white stripes with certain lengths are calculated and reserved at intervals of each photo, and finally cutting is carried out after END is printed at the tail of the paper.
And then manually completing secondary paper threading of the paper strips printed on the front side, enabling the back side of the double-sided printing photographic paper 2 to face upwards, leading the paper head to be in front, leading the paper tail with the END mark to be behind, starting to print a back side photo after paper threading, printing a specific boundary pattern on the back side corresponding to the paper head of the front side photo and the interval part of the photo according to algorithm calculation, detecting the specific boundary pattern through a sensor, and automatically completing cutting.
No matter how many double-sided photos can be finished according to the operation, the operation is very simple, the printed specifications are various, the printing can be carried out on photographic paper with various specifications including 5 inches, 6 inches, 8 inches, 12 inches and the like, and the maximum length of each photo can reach 3.2 meters.
