A stormjet advertisement printer user reported that the printing machine was running normally before, but after cleaning the print head, the color of the printed image became lighter. Similar problems may have occurred to other users. Therefore, stormjet advertisement printer group made the following simple analysis and solutions for this problem.

What caused this situation? We also need to analyze the structure and working principle of the stormjet advertisement printer, and most of the problems like this occur on printer with four colors arranged one above the other and relatively few inkjets. Because the ink is a volatile liquid, the ink dries quickly. In the case of a long cleaning time, the output media has strong permeability, and the inkjet pattern is likely to become lighter. After finding the reason, we looked for a symptomatic solution. Because it was caused by cleaning the print head, we should not clean the print head as much as possible during the printing process. Check the status of the print head before printing. If it is necessary to clean, clean it as soon as possible or separately to avoid chromatic aberration appears.
