Troubleshooting of abnormal manual paper feeding speed--Model XP

Troubleshooting of abnormal manual paper feeding speed--Model XP

When the manual paper feeding speed on the touch screen is abnormal

1.  First, check whether the radius of the winding is consistent with the manually measured value

 (1) Manually measure the actual winding radius (excluding the inflatable rod), method 1, use a ruler to measure the winding radius and winding radius respectively, and the unit is mm; Method 2: use a tape measure to measure the winding perimeter and unwinding perimeter respectively. Use the formula: winding radius = (paper roll perimeter /2 π) - 40mm to calculate the winding radius and unwinding radius
(2) Check the volume radius calculated by the machine self-test

Method 1: enter the "print monitoring" interface

Mode 2, enter "engineer mode 2"
"User settings" - > engineer settings - > enter password "1234" -> enter engineer mode - > long press the blank space in the lower left corner until the arrow appears -- > click the left arrow to enter "engineer mode 2"


Enter "12" in the address bar and click ", and the parameter bar displays the winding radius;
Enter "13" in the address bar and click ", and the parameter bar displays the unwinding radius;
(3) If the difference between the winding radius and the manually measured radius is greater than 10mm, you need to re-enter the winding radius in the "paper feeding system" interface, and confirm the input, and the self-test takes effect.
2. If the winding diameter is correct, check the number of pulses in one winding cycle
(1) Calculate the number of pulses in one winding cycle
Number of pulses per cycle = I value of turbine reducer * 600 (the legend is for reference only, and the I value is subject to the actual situation)


(2) Check the pulse number of one turn in the machine. If it is inconsistent with the actual calculated value, set the pulse number of one turn in and out of the machine to the actual calculated value.

(1) Method 1: check "user settings" - > engineer settings - > enter password "1234" -> enter the engineer mode - > Press and hold the blank space in the lower left corner until the arrow appears -- > click the right arrow to enter "engineer mode 1"


to modify the number of pulses in a winding cycle, you can directly enter the corresponding actual calculated value.

Method 2, "user settings" - > engineer settings - > enter password "1234" -> enter the engineer mode - > Press and hold the blank space in the lower left corner until the arrow appears -- > click the left arrow to enter "engineer mode 2"

Input "10" in the address bar and click ", and the parameter bar displays the number of pulses for one coil unwinding;

Input "11" in the address bar and click ", and the parameter bar displays the number of pulses for one winding cycle;

(3) Modify the pulse value of one turn of winding

Enter "10" in the address column, and enter the number of pulses for one cycle of unwinding in the parameter column. Click

Input "11" in the address column, input the number of pulses for one winding cycle in the parameter column, and click
3. If the first two items are correct, check the circumference of the spindle and the number of pulses in one cycle of the spindle.

（1）(1) The circumference of the spindle can be measured by checking the machine data or using a tape measure

（2) Number of pulses per revolution of spindle = 2840 * transmission ratio (transmission ratio can be read from the label of spindle motor reducer)The following figure shows that the transmission ratio is 50 (for reference only, the specific value should be subject to the actual reading value


Use the "machine setup" tool on the PC to check the circumference of the spindle and the number of pulses per revolution of the spindle online

After successfully online, enter the main interface, press "ctrl+e" with the keyboard to open cleaning settings and advanced settings

Click the "advanced settings" page, and then click "motion control"

You can see "spindle circumference" and "number of pulses per revolution of spindle" in the spindle acceleration curve bar.

(4) If the displayed value is inconsistent with the actual calculated value, modify the value in the column to the actual calculated value and "save the modification"
