Print Misalignment

Fedar digital advertising printing machine is the same as our daily office printer. It can achieve a highly restored image in the printout of advertising printing. If the user has no problem in operation and there is a problem of print misalignment, the customer can use the following to find the source of the problem and solve it.

1.Check if the car where the printhead is located is not moving smoothly. The movement of the photo car is the key to controlling the printhead to achieve precise positioning of the inkjet. If there is too much resistance during the movement process, which will cause jams, etc., it will cause the printhead disorderly and the printed image will be misaligned.At this time, it is necessary to check whether the gaskets, copper sleeves, etc. of the car are seriously worn. After cleaning, remember to add a little lubricating oil to solve it satisfactorily.

2.Check whether the encoder strip of the digital advertising printing machine is the same as that under normal working conditions. Because the encoder strip is the key to positioning the image and cannot tolerate a little bit of dirt, if it is detected, it needs to be cleaned, especially in the daily use of printing machines, it is susceptible to the influence of space dust and other inks, which will affect the use of encoder strip.Therefore, the user can clean the encoder strip and then perform the print test. If the encoder strip is defective, it can also be replaced with a new one, and the cost is also cheap.

3.Two-way calibration.The first major thing after buying a digital advertising printing machine is to calibrate the working state of it.Only when the working state is set can it be taken efficiently, without the problems caused by other non-quality failure.
