When the photo machine is printing, there is no problem in the place of small ink volume, but the drawing of the large color block appears, which affects the normal operation of the photo machine. How to solve this situation?
For this kind of failure, we can analyze it from the following aspects:
First, there is a problem with the motherboard. Problems with the motherboard may cause deviations in the print order processing, resulting in a printout of the print page when the printhead executed the wrong command while printing.
Second, the nozzle has a light blockage. When printing the test, the pattern can be printed. Many users will not think that the nozzle is lightly clogged. If the nozzle is not clogged, the ink can be ejected, but the spray is not smooth and the amount of ink is small. There is a phenomenon of drawing and drawing.
Solving the above problem is also relatively simple. We can use the exclusion method to find out where the problem lies. For example, find a normal nozzle to replace it, and use the replacement method to find the problem. If the problem still occurs, the motherboard is faulty. The motherboard can be replaced.
