Common faults and solutions for inkjet printers (CIJ inkjet printers)

When we use the cij printer, we always encounter this and that problem. In fact, the common problems during the use of the inkjet printer are mainly summarized in the following aspects. When we find common failure phenomena, we also find the inkjet printer. Solution to printer failure: Symptoms and solutions of printer failure: 1. The nozzle of the printer is clogged and the nozzle is dripping ink. You can execute the nozzle opening procedure and perform nozzle flushing;   2, there is no ink pressure, please check the ink in the ink tank Add tube to bet or not, and check whether the filter should be replaced, and then adjust the ink pressure to the specified value;   3, the main ink filter is seriously clogged, replace the main ink filter;   4, the single-chip microcomputer board is disturbed, restart, edit characters, set parameters , It can also be solved by discharging the printer mainboard static electricity. There is no break point in the ink line of the printer. Solution:   1. The ink viscosity is very high or very low. Replace the ink and run again. You can also change the ink dot voltage or adjust the entire printer frame;   2, the nozzle is blocked, and the nozzle is opened. ;  3. Contact the service engineer to solve the problem of the spray cavity. Blurred printing (bad ink line breakpoint) solution    solution:   1, the breakpoint value is improperly adjusted, adjust the breakpoint value, you can adjust the breakpoint value while printing, until the appropriate value;   2, the phase light is always on or flashing;   3, The ink viscosity of the printer is incorrect, adjust the ink viscosity;   4, the nozzle is slightly clogged, execute the nozzle opening procedure;   5, the main ink filter of the printer is clogged, clean and replace the main ink filter;   6, the ink pressure is improperly adjusted, according to the user manual It is stipulated to adjust the ink pressure of the cij printer;   7, the positive pressure air of the nozzle is adjusted too large, and the positive pressure air of the inkjet printer is reduced. Solution to the nozzle clogging of the printer   Solution steps:   1, execute the nozzle opening procedure, if there is no effect, you can block the reclaimer port and increase the ink pressure to open the printer nozzle;   2, use the nozzle wrench to remove the nozzle and put it into the installation Soak in the thinner or cleaning agent container for a period of time and then try again;   3. If there is an ultrasonic cleaner, use an ultrasonic cleaner to clean the nozzle of the inkjet printer.  Note: When reinstalling, be careful not to install it backwards, and install with the lettering side down. The printing effect of the cij printer is not ideal, and the characters that are ejected are garbled or misplaced. Solution   Solution:   1. Editing error, can not use arrow keys instead of space bar, or the content that should be deleted is cleared;   2, spray The main board of the cij printer's MCU board is disturbed, please clear the screen and edit again, or switch the machine to try again. The printer often displays the fault 'lack of diluent' during use. Solutions:   1. There is no or little diluent in the diluent bottle. Refill the diluent to the printer box;   2. Proximity switch assembly and diluent bottle If the distance is long and cannot be detected, adjust the position of the diluent bottle to make it close to the proximity switch; 3. Reduce the sensitivity of the proximity switch, adjust the potentiometer on the proximity switch to increase the detection sensitivity and ensure the accuracy of the inkjet signal triggering.
