Simple tips to teach you how to repair inkjet printers

The more advanced the inkjet printer equipment, the more difficult it is to maintain! At this time, not only the consumable parts of the inkjet printer are required to be undamaged, but also the faults of the machine need to be solved quickly so as not to affect the production. Therefore, many large companies often have their own professional inkjet printer maintenance team. Many experienced maintenance masters can quickly find the problem of the inkjet printer, and it is difficult for people with less experience to find out the cause at once. Where. Based on the basic knowledge of inkjet printers and inkjet printer consumables, the following editor will explain to you how to use the inkjet printer if some common failures or problems occur in the machine, how to be timely and efficient deal with. 1. High pressure failure: the reason is that the high pressure sensor detects high pressure imbalance. Specific reasons: a. A foreign object hits the high-voltage deflection plate. b. The high-pressure deflection plate is dirty. c. The high-pressure sensor itself is too sensitive. Solution: au0026b clean the high-pressure deflection plate, and then turn it on normally. c. If this is the case, high-voltage failures may be reported frequently, but the deflection plate is very clean. It needs to be solved by an engineer. 2. Charging failure: specific reasons: a. There is ink on the charging tank b. Charging ink dot detection failure solutions: a. Turn off the printer (including the power supply), and clean the charging tank. If necessary, the charging tank can be removed for cleaning. After cleaning thoroughly, wait for the charging tank to dry, and then restart the machine. b. There are many reasons for this failure, starting with ink. To determine the viscosity and shelf life of the ink, of course also depends on the quality of the ink. Then observe the split, check the ink circuit pressure, modulate the voltage, and make appropriate adjustments to make the split good. This fault can generally be resolved. It is also possible that the charging slot itself is damaged. 3. Characters are missing and the ink dots fall to the edge of the recycling pipe, causing ink to hang on the recycling pipe (ink accumulation in the recycling pipe). Specific reasons: a. Whether the ink line position is correct. b. Whether the ink dot split is normal. c. Is the ink normal (ink viscosity BFT, ink shelf life) d. Is the printer grounding effective (often ignored by customers and some engineers), grounding is very important, and the consequences are serious! 4. Recovery tube failure The recovery tube sensor does not detect ink flowing through the recovery tube. Specific reasons: a. The ink line is abnormal (no ink line is ejected at all, or the ink line is biased) b. The recovery line is blocked c. The recovery sensor is damaged or not connected. Solution: a. Check the ink supply circuit. Clean the nozzle plate and do ink line correction work. b. The recovery pipe is blocked, and the blockage position of the recovery pipe can be checked in sections. c. Check whether the connector of the recovery tube sensor on the main board is not installed correctly. Replace the recovery tube sensor. 5. Ink viscosity failure The ink viscosity BFT value exceeds the standard. In some cases, the machine can be used normally. But some checks must be done. Otherwise, it may not be able to print normally after using for a period of time. Reason: a. The current value of ink BFT is greater than the set value of ink BFT. The ink viscosity is too high. b. The current value of ink BFT is less than the set value of ink BFT. The ink viscosity is too low. Solution: a. Check if there is solvent in the solvent tank. Check whether the solvent addition circuit is normal. b. Whether it is turned on and off many times in a short period of time. If it is not turned on and off multiple times in a lot of time. Check whether the solvent addition circuit is normal.
