[0002] When printing, the image forming device needs to transport paper from the paper box to the imaging unit. During the paper transport process, due to poor paper separation, the previous paper may be transported out of the paper box and part of the next paper may be taken out of the paper box.

[0056] Figure 1 The following is a flow chart of a paper spacing adjustment method provided by an embodiment of the present invention. Figure 1 As shown in , the method includes:

[0057] Step 101: determining a theoretical paper feeding time and an actual paper feeding time of a first paper.

[0058] The actual paper feeding time is the actual time taken by the image forming device to transport the paper from the paper box into the image forming device. The theoretical paper feeding time is the theoretical time calculated based on the distance from the paper box to the paper feeding path of the image forming device and the speed at which the paper feeding element transports the paper.

[0059] A paper feed sensor may be provided between the paper box and the imaging unit of the image forming device to sense the transport of the paper, and the actual paper feed time may be determined according to the time when the paper head reaches the paper feed sensor. Figure 2 A schematic diagram of paper feeding provided by an embodiment of the present invention. Figure 2 As shown in , a plurality of sheets of paper are loaded in the paper box 201, and the paper feed element 202 is in direct contact with the topmost sheet of paper in the paper box 201. When the paper feed element 202 rotates counterclockwise, the sheets of paper in the paper box 201 are transported to the imaging unit 204. A paper feed sensor 203 is provided on the paper feeding path between the paper box 201 and the imaging unit 204. The actual paper feed time is the time taken from the start of the rotation of the paper feed element 202 to the arrival of the paper head of the paper at the paper feed sensor 203. When calculating the actual paper feed time, the first moment when the paper feed element 202 starts to transport the first sheet of paper can be determined, and then the second moment when the paper head of the first sheet of paper arrives at the paper feed sensor 203 can be determined, and finally the actual paper feed time of the first sheet of paper can be determined according to the first moment and the second moment.

[0060] Specifically, when the first paper in the paper box 201 starts to be fed, the paper feed element 202 starts to rotate counterclockwise to feed the paper and the timing starts at the same time. The first paper is transported to the imaging unit 204 driven by the paper feed element 202. Taking the paper feed sensor 203 as a photoelectric sensor as an example, before the paper head of the first paper reaches the paper feed sensor 203, the photosensitive element in the paper feed sensor 203 can receive the irradiation of ambient light and is in a photosensitive state. When the paper head of the first paper reaches the paper feed sensor 203, the paper feed sensor 203 is covered by the paper head of the first paper. At this time, the photosensitive element in the paper feed sensor 203 cannot receive the irradiation of ambient light and changes from a photosensitive state to a non-photosensitive state. At this time, the timing is stopped to obtain the actual paper feeding time of the first paper.

[0061] For another example, the paper feed sensor 203 is implemented in the form of an infrared sensor, and the paper feed sensor 203 specifically includes a transmitting end and a receiving end. The transmitting end is used to transmit infrared rays, and the infrared rays are irradiated on the object to be measured to generate reflected infrared rays. The receiving end receives the reflected infrared rays to measure the distance between the object to be measured and the paper feed sensor 203. When the paper head of the first paper reaches the transmitting end of the paper feed sensor 203, the infrared rays emitted by the transmitting end are reflected by the paper head of the first paper and enter the receiving end. The receiving end detects that the distance between the receiving end and the object to be measured becomes shorter based on the received reflected infrared rays, thereby determining that the paper head of the first paper has reached the paper feed sensor 203, and then stops timing.

[0062] In some embodiments, when calculating the theoretical paper feeding time, the theoretical paper feeding speed of the image forming device and the paper feeding distance between the paper box and the paper feeding sensor of the image forming device can be determined first. Figure 2 The paper feeding distance is determined by the rotation speed of the paper feeding element 202 shown in FIG. Figure 2 The distance from the edge of the paper box 201 near the paper feeding element 202 to the paper feeding sensor 203 is shown in FIG. Then, the theoretical paper feeding time is obtained according to the theoretical paper feeding speed and the paper feeding distance. That is, the theoretical paper feeding time = paper feeding distance / theoretical paper feeding speed.

[0063] Step 102: determining a paper feeding time deviation of a first paper according to a first difference between an actual paper feeding time and a theoretical paper feeding time.

[0064] The paper feeding time deviation is the deviation between the actual paper feeding time and the theoretical paper feeding time, which can be determined by a first difference obtained by subtracting the theoretical paper feeding time from the actual paper feeding time. For example, when the actual paper feeding time is 3 seconds and the theoretical paper feeding time is 2 seconds, the first difference is 3-2=1 second, and the 1 second is the paper feeding time deviation.

[0065] Among them, when the actual paper feeding time is greater than the theoretical paper feeding time, the first difference is a positive number, indicating that the first paper has experienced a paper feeding slippage phenomenon, thereby causing the paper spacing between the first paper and the previous paper to become larger. Among them, the paper feeding slippage phenomenon specifically refers to the phenomenon that during the paper feeding process of the image forming device, the paper cannot smoothly enter the image forming device from the paper box, or stops moving shortly after entering, or even the paper slips at the paper feed port. When the actual paper feeding time is less than the theoretical paper feeding time, the first difference is a negative number, indicating that due to the poor paper separation, the image forming device brought a portion of the first paper out of the paper box in advance when feeding the paper before the first paper, thereby causing the paper spacing between the first paper and the previous paper to become smaller.

[0066] Figure 3 A schematic diagram of paper slipping provided by an embodiment of the present invention. Figure 3 As shown in FIG. 2 , after the paper feeding element 202 completes the conveyance of the paper 205, it continues to convey the next paper 206 in the paper box 201. The paper feeding element 202 slips during the conveyance of the paper 206, and the actual paper feeding time of the paper 206 is greater than the theoretical paper feeding time. The distance between the paper 205 and the paper 206 becomes larger.

[0067] Figure 4 A schematic diagram of continuous feeding / repeated feeding of paper provided in an embodiment of the present invention. Figure 4 As shown in FIG. 2 , the paper feed element 202 is conveying the paper 205. However, due to poor paper separation, the paper feed element 202 brings part of the next paper 206 out of the paper box 201 during the conveying of the paper 205. At this time, the position of the paper 206 is outside the paper box 201. Therefore, before the paper feed element 202 conveys the paper 206, part of the paper 206 is no longer in the paper box 201. At this time, the distance between the paper head of the paper 206 and the paper feed sensor 203 becomes smaller. When the paper 206 is subsequently conveyed, since the distance between the paper head of the paper 206 and the paper feed sensor 203 becomes smaller, the time for the paper head of the paper 206 to reach the paper feed sensor 203 becomes shorter when the rotation speed of the paper feed element 202 remains unchanged. As a result, the actual paper feed time of the paper 206 is less than the theoretical paper feed time, so that the paper spacing between the paper 205 and the paper 206 becomes smaller. If the paper spacing between paper 205 and paper 206 is small to a certain extent, the leading end of paper 206 will reach paper feed sensor 203 just when the trailing end of paper 205 passes through paper feed sensor 203. Since the distance between the trailing end of paper 205 and the leading end of paper 206 is too short, paper feed sensor 203 cannot sense the change in the photosensitivity state, resulting in a paper jam.

[0068] Step 103, determining a paper spacing correction value between the first paper and the second paper according to the paper feeding time deviation, wherein the second paper is the next paper adjacent to the first paper.

[0069] Since the unit of paper spacing is length and the unit of paper feeding time deviation is time, it is necessary to convert the unit of paper feeding time deviation from time to length when calculating the paper spacing correction value. Specifically, the first distance can be calculated based on the paper feeding time deviation and the theoretical paper feeding speed of the image forming device. The first distance is the deviation value of the paper spacing caused by paper feeding slippage or continuous paper feeding, and the first distance is specifically the deviation of the paper spacing between the first paper and the previous paper of the first paper. Therefore, it is necessary to adjust the paper spacing between the first paper and the second paper after it. Therefore, the first distance can be determined as the paper spacing correction value between the first paper and the second paper. For example, during the printing output process, the paper feeding element transports the three sheets of paper P1, P2 and P3 in the paper box to the imaging unit in sequence. After the paper feeding element transports the paper P1, it starts to transport the paper P2, and the paper feeding time deviation is calculated based on the actual paper feeding time and the theoretical paper feeding time of the P2 paper, and the first distance is calculated based on the paper feeding time deviation and the theoretical paper feeding speed of the image forming device. Finally, a paper spacing correction value is obtained according to the first distance, and the paper spacing between the paper P2 and the paper P3 is corrected according to the paper spacing correction value.

[0070] Step 104 , adjusting the paper spacing between the first paper and the second paper according to the paper spacing correction value.

[0071] The paper spacing between the first paper and the second paper includes two parts: the first part is the spacing between the first paper and the second paper, and the second part is the length of the first paper in the paper box when the paper head of the first paper reaches the paper feed sensor. Figure 5 A schematic diagram of paper spacing provided by an embodiment of the present invention. Figure 5As shown, when the leading edge of the paper 205 reaches the paper feed sensor 203, a part of the paper 205 is outside the paper cassette 201 and a part is still in the paper cassette 201. When the leading edge of the paper 205 reaches the paper feed sensor 203, after passing the length of the paper 205 in the paper cassette 201 plus the distance between two sheets of paper, the paper feed element 202 feeds the next sheet of paper of the paper 205. For example, the length of the paper 205 is 29.7 cm, and the distance between the edge of the paper cassette 201 close to the paper feed element 202 and the paper feed sensor 203 is 5 cm. When the distance between two sheets of paper is 2 cm, when the leading edge of the paper 205 reaches the paper feed sensor 203, 5 cm of the length of the paper 205 is outside the paper cassette 201 and 24.7 cm of the length is still inside the paper cassette 201. Then the theoretical paper distance between the paper 205 and the next sheet of paper is 24.7 cm + 2 cm = 26.7 cm. When the leading edge of the paper 205 reaches the paper feed sensor 203, after another 26.7 cm of length, the next sheet of paper starts to be transported, so that the distance between the paper 205 and the next sheet of paper is 2 cm.

[0072] Therefore, when adjusting the paper distance between the first sheet of paper and the second sheet of paper according to the paper distance correction value, it is necessary to first obtain the first size information of the first sheet of paper. Then, based on the first size information, the theoretical paper distance between the first sheet of paper and the second sheet of paper is obtained. This theoretical paper distance is the length of the part of the first sheet of paper that is still in the paper cassette when the leading edge of the first sheet of paper reaches the paper feed sensor plus the distance between the first sheet of paper and the second sheet of paper. Then, according to the theoretical paper distance and the paper distance correction value, the first paper distance is obtained as the paper distance between the first sheet of paper and the second sheet of paper. Among them, the first paper distance can be calculated by formula (1).

[0073] Formula (1):

[0074] L = L_theory - L_correction

[0075] Among them, L is the corrected first paper distance, L_theory is the theoretical paper distance, and L_correction is the paper distance correction value.

[0076] Among them, L_correction can be calculated according to formula (2).

[0077] Formula (2):

[0078] L_correction = △t * V

[0079] Among them, △t is the paper feed time deviation, and V is the theoretical paper feed speed of the image forming apparatus.

[0080] △t can be calculated according to formula (3).

[0081] Formula (3):

[0082] △t=t1-t

[0083] Among them, t1 is the actual paper feeding time, and t is the theoretical paper feeding time.

[0084] In some embodiments, when controlling the paper spacing between the first paper and the second paper according to the corrected first paper spacing, the paper feeding time of the second paper is often controlled. That is, after the paper head of the first paper reaches the paper feed sensor for a certain time, the second paper starts to be fed. Therefore, it is necessary to convert the first paper spacing calculated above from a length unit to a time unit. Therefore, the first time length can be calculated based on the theoretical paper feeding speed of the image forming device and the first paper spacing. The first time length is the time length required to transport the length of the first paper spacing according to the theoretical paper feeding speed. Then, the second paper can be fed after the paper feeding time of the second paper reaches the first time length of the paper head of the first paper reaching the paper feed sensor.

[0085] During the implementation process, the paper spacing of an image forming device with poor paper feeding performance will be enlarged, and the △t calculated by formula (3) is a positive number. The paper spacing of an image forming device with poor paper feeding separation will be reduced, and the △t calculated by formula (3) is a negative number. The L compensation calculated in formula (2) is the paper spacing deviation between the current paper and the previous paper. Therefore, when the next paper is transported, the L compensation is added in. In this way, the correction is made piece by piece to offset the L compensation generated by each page of paper during paper feeding within one minute, thereby achieving the standard and stability of the PPM of the image forming device. For image forming devices with a high continuous feeding rate, since △t is a negative number, the actual paper spacing L after correction will be larger than the original theoretical paper spacing L, and the two pages of paper that may have been connected and caused a paper jam will be pulled apart to avoid continuous feeding jams.

[0086] In some embodiments, the embodiment of the present invention corrects the next page of paper according to the expansion or contraction of the actual paper spacing of the previous page of paper. Therefore, there is a certain lag in the implementation process. When the paper head of a certain page of paper reaches the paper feed sensor after a long paper feed time due to serious slipping or other reasons, the resulting paper feed time deviation △t will be relatively large. If the paper feed time deviation △t is directly used to correct the paper spacing of the next page, the corrected actual paper spacing L calculated according to formula (1) will be relatively small, and at this time, paper jams similar to continuous feeding may occur. Therefore, by setting a first threshold to constrain the paper spacing correction value, when the first distance (i.e., the paper spacing correction value) in the above is greater than the first threshold, the paper spacing of the next page is forced to be corrected according to the first threshold. That is, when the first distance is greater than the first threshold, the first threshold is used as the paper spacing correction value. When the first distance is less than or equal to the first threshold, the first distance is used as the paper spacing correction value. This ensures that the PPM of the image forming apparatus is increased as much as possible without paper jams. Among them, the specific value of the first threshold can be determined according to factors such as the paper feed performance of the image forming apparatus and the characteristics of the paper feed sensor.

[0087] In a specific example, based on the content of the above embodiments, the embodiment of the present invention provides another paper spacing adjustment method. Figure 6 It is a flowchart of another paper spacing adjustment method provided by the embodiment of the present invention. As Figure 6 shown, the method includes:

[0088] Step 601, printing starts.

[0089] The image forming apparatus starts printing in response to the received printing task.

[0090] Step 602, start paper feeding, and start timing while starting the paper feeding element.

[0091] Among them, the paper feeding element can be implemented in the form of a paper feed roller, and the image forming apparatus transports the paper in the paper cassette to the imaging unit by controlling the rotation of the paper feed roller.

[0092] Step 603, stop timing after the paper feed sensor changes from the photosensitive state to the non - photosensitive state to obtain the actual paper feed time. At the same time, start paper spacing timing, and the timing duration is Ltheo / V - Lcomp / V.

[0093] Among them, the timing duration: Ltheo / V - Lcomp / V is derived according to formula (4).

[0094] Formula (4):

[0095] L / V

[0096] Among them, formula (4) is used to calculate the timing duration.

[0097] Substituting formula (1) L = L theory - L complement into formula (4), we can get (L theory - L complement) / V. Further expansion can get the timing duration = L theory / VL complement / V.

[0098] The change of the paper feed sensor from the light-sensitive state to the light-insensitive state indicates that the paper head of the paper reaches the paper feed sensor. The purpose of starting the paper interval timing is to calculate the paper feed time of the next page of paper.

[0099] Step 604: Calculate the first distance according to the actual paper feeding time and the theoretical paper feeding time.

[0100] The paper feeding time deviation is first obtained according to the actual paper feeding time and the theoretical paper feeding time, and then the first distance is calculated according to the paper feeding time deviation and the theoretical paper feeding speed.

[0101] Step 605, determine whether the first distance is greater than a first threshold, if yes, execute step 606, if no, execute step 607.

[0102] Step 606: The paper spacing correction value is set to a first threshold.

[0103] Step 607: The paper spacing correction value is set to the first distance.

[0104] Step 608, the paper spacing timing ends.

[0105] When the paper gap timer ends, the next paper can be fed.

[0106] Step 609, determine whether there is a next page of paper, if yes, go to step 602. If no, go to step 610.

[0107] Step 610, printing ends.

[0108] Through the above paper spacing adjustment method, the actual paper spacing of the image forming apparatus during continuous printing of multiple sheets of paper is close to the theoretical paper spacing, thereby ensuring the compliance and stability of the PPM parameter. For example, when feeding 7 sheets of paper from P1 to P7, the feeding order is P1, P2, P3, P4, P5, P6, P7. According to the actual feeding time of each sheet of paper, the feeding time deviation of each of the papers from P1 to P7 can be obtained, which are Δt1, Δt2, Δt3, Δt4, Δt5, Δt6, and Δt7 in sequence. Then, the corrected paper spacing calculated between P1 and P2 is Ltheo - Δt1×V. The corrected paper spacing calculated between P2 and P3 is Ltheo - Δt2×V. The corrected paper spacing calculated between P3 and P4 is Ltheo - Δt3×V. The corrected paper spacing calculated between P4 and P5 is Ltheo - Δt4×V. The corrected paper spacing calculated between P5 and P6 is Ltheo - Δt5×V. The corrected paper spacing calculated between P6 and P7 is Ltheo - Δt6×V.

[0109] After the image forming apparatus performs paper spacing control on the 7 sheets of paper from P1 to P7 based on the corrected paper spacing, the actual paper spacings are as follows: The actual paper spacing between P1 and P2 is Ltheo - Δt1×V + V*Δt2. The actual paper spacing between P2 and P3 is Ltheo - Δt2×V + V*Δt3. The actual paper spacing between P3 and P4 is Ltheo - Δt3×V + V*Δt4. The actual paper spacing between P4 and P5 is Ltheo - Δt4×V + V*Δt5. The actual paper spacing between P5 and P6 is Ltheo - Δt5×V + V*Δt6. The actual paper spacing between P6 and P7 is Ltheo - Δt6×V + V*Δt7.

[0110] From the above content, the actual total paper spacing length for printing 7 sheets can be obtained as: 6*Ltheo - V*Δt1 + V*Δt7. This value is already very close to the total theoretical paper spacing of 6×Ltheo for printing 7 sheets. That is, when printing n + 1 sheets, the actual paper spacing generated is n*Ltheo - V*Δt1 + V*Δt(n + 1), which is very close to the total theoretical paper spacing length of n*Ltheo, thereby proving that the paper spacing adjustment method provided by the embodiment of the present invention can, while avoiding paper jams,尽可能提高图像形成装置的PPM参数,并保证PPM参数达标。

[0111] Corresponding to the above paper spacing adjustment method, an image forming apparatus is provided in an embodiment of the present invention. Figure 7 It is a schematic structural diagram of an image forming apparatus provided in an embodiment of the present invention.
