How to set up a common problem handling process for inkjet printers

For printer users, it is very important to do SOP. Print out some common problems in the form of a list. When problems arise, they can be used to compare the situation at any time. If the problems are found to be similar or the same, you can follow the instructions in the solution. The maintenance process is carried out in 1, 2, and 3 steps, which greatly improves the efficiency and ensures the smooth progress of our production work. Here are a few common SOP operation guides for inkjet printer failure maintenance methods, for reference by users. 1. The inkjet printer is abnormally charged. Some imported brand inkjet printer series models sometimes give an alarm to indicate the failure. This failure will not immediately prevent the inkjet printer from printing information, but there will be certain hidden dangers that will affect the inkjet printer It works normally, so it must be paid attention to for maintenance. Treatment method: This situation has a high occurrence rate and is relatively simple to deal with, that is, after the nozzle is cleaned and dried, the nozzle filter pipeline is guaranteed to be unblocked and the viscosity is normal. 2. Ink line splitting is not good, and printing information is blurred. In the process of long-term continuous operation, the inkjet printer sometimes fails to add diluent in time, which causes the ink path viscosity to be uncontrollable. At this time, the printing information is blurred and the ink line division is not good. Solution: The staff at the production line finds that the printing effect is not good. First, check whether the inkjet printer has an alarm for missing consumables, and add it in time if there is any; in addition, check whether the nozzle is clean and whether it needs cleaning; solve the above two points Then, after adjusting the charging value, adjust and adjust the ink dot splitting of the printer at the best break point to ensure that the charging deflection is normal. 3. Poor recycling of ink circuit, ink leakage, etc. First of all, we must judge the degree of poor recycling. Generally, it can be divided into two different situations: incomplete recycling and no recycling at all. Long-term use may lead to incomplete recycling caused by clogging of the recycling pipeline. Complete, ink addition or main filter clogging, venturi clogging, in addition to pump damage or nozzle solenoid valve damage may also lead to poor recovery. If it is not recovered at all, it may be related to the circuit control according to the situation, such as whether the recovery solenoid valve is working normally, whether the spool coil is on and off normally, from these two aspects, the problem can be basically judged, and the problem can be quickly targeted after knowing the problem. To solve the problem, there is a little trick here is to soak the nozzle recovery tank in the cleaning agent and use the ink supply pressure to open it. If the ink line is unstable, the disorder is usually caused by impurities in the ink system, clogged nozzles, and whether the pressure is normal, etc. In addition, it depends on whether the maintenance time of the inkjet printer has expired. If there is no maintenance for a long time, the inside of the filter There will be a lot of stains, which will affect the stability of the printer.
