First of all, let’s analyze the reason why the inkjet printer can’t type clearly? We all know that the inkjet printer is composed of two parts: ink path and circuit. Once it has been operated for a long time, the position of the ink line will change slightly, resulting in missing words or characters in the inkjet printing. In addition to environmental factors, with the increase of impurities, it will lead to poor charging and deflection, resulting in unclear typing.
Secondly, do you know what else causes the poor typing effect of the inkjet printer? Of course, there is also the consumable ink used by the inkjet printer, such as whether the ink viscosity is normal, whether the ink is within the shelf life, and so on.
Finally, whether the inkjet printer is effectively grounded: grounding can be divided into two types: protective grounding and anti-interference grounding. Anti-interference grounding is used for inkjet printer. If protective grounding is used, it will only cause greater instability.
After understanding the causes, we can summarize some solutions based on these problems.
1. First, stop the inkjet immediately, then open the protective cover of the inkjet, and check whether there is ink accumulation on the surface of the nozzle, charging tank, recycling tank, etc., and whether it is polluted by ink. If it is very dirty, the solution is to prepare a metal or plastic beaker with good grounding to receive the waste liquid, to prevent the waste liquid from polluting the product, machine or ground, and to prevent the appearance of open fire. After the printing head is cleaned, re-open the ink line, observe the ink line condition, recycling condition, and the split condition of the ink point. If there is no problem in the monitoring, cover the printing head cover again and start printing, then complete the processing and repair of the unclear printing of the printer.
2. To clean the nozzle, first ensure that the modulation is the correct setting, including the correct pressure value and charging value. It should be noted that after changing or cleaning the printer, it is necessary to ensure that the nozzle is dry before starting the printing function.
After understanding the causes and solutions of unclear inkjet printer, let’s talk about another factor that will occur in inkjet printer: what about half of the inkjet printer? The inkjet printer prints half of the information, either the head is not displayed or the tail is not displayed. If there are multiple lines of information, there may be a line at the top or bottom that is not printed. What is the reason for this? The reasons are as follows:
1) . The recovery tank is hung with ink. If there is accumulated ink under the recycling tank, the deflected ink droplets will be blocked, and the incomplete printing will be formed.
2) . Poor charging. It refers to that a certain amount of electric charge is not charged according to the predetermined value, resulting in the deviation distance not reaching the standard, thus forming the phenomenon of half a character or font not beautiful.
3) . Insufficient high pressure. If the high pressure is insufficient, the deflected words will also be weak, unable to reach the expected flight deflection position, and will also result in poor or half typing
To sum up, we believe that you have a certain understanding of the poor typing of the inkjet printer. If you still can’t solve the problem, you need to contact the maintenance engineer of the inkjet printer manufacturer for remote guidance and correct handling or make an appointment with the manufacturer for on-site maintenance.
