How to adjust the printing density of HOP-E300：
First, check the self check page and it shows that the current concentration is 1. Then I adjusted the concentration to 2. The self-test shows a concentration of 2.
There are a total of four concentrations, and when the highest concentration is 4, the concentration will become 1 when operating again. The concentration of 1-2-3-4-4-1-2-3 changes in a cyclic manner.
