In the process of "serving" us for a long time, weird failures are almost inevitable; in order to ensure that the inkjet printer can work efficiently, many people are concerned about frequent inkjet printing failures and The troubleshooting process is summarized, so that in the future, if you encounter a fault with the same phenomenon in the future, you will be able to prepare for it and quickly eliminate it in a targeted manner.
Fault 1. Recently, the inkjet printer in the office of the unit has been performing automatic cleaning operation almost every day. Is this phenomenon normal?
Under normal circumstances, inkjet printers generally do not automatically clean the nozzles frequently. If we unfortunately encounter this phenomenon, it is likely that the control circuit of the inkjet printer has failed. The operation of automatic cleaning of the print head is based on the inkjet printer's program settings and actual use. It is only necessary when the cleaning of the print head occurs frequently or the cleaning operation is constantly performed. At this time, we must send it to a professional repair station for repair in time. Considering that the inkjet printer is a relatively precise electromechanical integration device, the motherboard control chip of the inkjet printer can accurately perform the paper feeding operation, the paper feeding operation, the paper discharging operation and the print head moving operation under the cooperation of various precision mechanical parts. Print the content of the target material on the corresponding printing paper accurately. The problem of frequent cleaning of the print head is not necessarily the problem of the print head itself. It may also be that the ink supply system, ink delivery system and even the print control circuit related to printing have failed. These factors may cause printing The nozzle is frequently cleaned.
Trouble two, after the inkjet printer uses the continuous ink supply method, the print head is damaged, and the inkjet printer heads of different models and the same type are used for replacement. Can this replacement method be used?
As everyone knows, the nozzle is one of the most precise and important parts in the inkjet printer equipment. In addition to the very strict process flow and production environment required in the manufacturing process, it also guarantees storage, transportation, installation, and replacement. There are strict requirements in the link, and any irregular or improper operation may cause serious damage to the print head quality or even be scrapped directly. Although in many printer models, the inkjet printers of the same brand may encounter the situation that the print heads are common to each other, but universal also requires us to use manual methods to replace and install, and this operation process often requires a high degree of precision , So we must not arbitrarily use other types of inkjet print heads to replace, to avoid damaging the output nozzles of inkjet printers, thereby causing unnecessary economic losses to ourselves.
Trouble three: When using an inkjet printer to print a black-and-white document, we often find that the printed pages contain colored horizontal lines, and these horizontal lines appear to be irregularly arranged.
When we encounter the phenomenon of incorrect output color, ink leakage, clogging, etc., or when printing black and white documents using inkjet printers and encounter color horizontal lines, we can probably judge that the above phenomenon is caused by damage to the inkjet printhead. In general, there are many causes of inkjet printhead damage, but they can be roughly divided into hard faults and soft faults. From the above fault description, we think that the inkjet print head should be physically damaged, so we must promptly send the inkjet printer to the designated maintenance point to replace the print head. If the print cartridge and the nozzle are integrated, then we should not hesitate to replace the entire print cartridge.
Trouble four: An inkjet printer can print a single sheet of paper, but it will automatically stop printing when printing more than two sheets at the same time. At the same time, the power light of the inkjet printer will continue to blink. When the print user disconnects the printing When the power is turned on again, the printing inkjet head will make a strange sound. Although the inkjet printer can be reset normally, the above problems will occur repeatedly.
When encountering the above-mentioned fault phenomenon, most of the foreign objects accidentally entered the inkjet printer or the mechanical parts of some printers have worn out and aging phenomenon, which caused the printing word car to not run smoothly, and may even cause the printing word car to be stuck. dead. Therefore, in order to extend the service life of the mechanical parts of the printer as much as possible, we recommend that you usually use slightly better quality printing paper when printing materials, and be sure to close the upper cover of the inkjet printer when using and placing the inkjet printer. , To avoid the impact of printing paper dust, air dust, etc. on the mechanical parts of the printer. If some printing parts are worn out and the printing carriage cannot run normally, we should send the inkjet printer to the designated repair station for repair.
Trouble five, when the inkjet printer starts the self-test, the belt and motor of the printing car make strange noises. And this phenomenon occurs every time the printer is turned on, but the inkjet printer is normal during the process of printing materials. Is this phenomenon normal?
In fact, this is an abnormal phenomenon. Although the inkjet printer may make a sound during the work, there should be no abnormal noise between the belt of the printing car and the motor. Once accidentally encountering the above phenomenon, we should first carefully check whether any foreign objects have accidentally entered the inkjet printer. If foreign matter enters accidentally, it will often cause the operating load of the inkjet printer's character car and motor and other related components to increase or scratch the character car belt. At this time, we may carefully refer to the printer's built-in installation manual to carefully remove one of them foreign matter. If it is found that the foreign matter in the inkjet printer has entered a deep position or stuck, we must ask a professional maintenance person to repair it. It is necessary to remind friends that the printing failure of inkjet printers is probably due to the use of a relatively low-quality continuous ink supply system and compatible ink cartridges, which can easily cause ink leakage accidents and leaks. The printing ink will increase the running resistance of the mechanical accessories of the inkjet printer, and the additional piping of the inkjet printer using the continuous ink supply system will also bring additional burden to the printing carriage and the printing motor.
Fault six, the inkjet printer has discontinuous color bars during the printing process. When playing the test page, it was found that the distribution of the blue and light blue color blocks was wrong, the position was incorrect, and the problematic hole was still uncertain.
There are two possibilities for this kind of failure. First, there is a problem with the ink cartridge, or the amount of ink is insufficient, or a non-genuine ink cartridge; second, it may be that the printer is used for a long time, and the components such as the pump and pump accessories are worn out, resulting in insufficient sealing. The first way to solve the problem is to check whether the ink cartridge installation position is correct. The user can install the ink cartridges in accordance with the installation order of the ink cartridges in the User Manual and the printer body. When the nozzle detection sample is broken, you can perform 1 to 2 cleaning operations (the cleaning operation consumes a certain amount of ink, so we recommend not to perform more than 3 cleaning operations. In addition, to improve cleaning efficiency, you can also try Allow the printer to stand for a period of time between cleaning operations). If the cleaning operation is invalid, it can only be sent to the repair center for repair.
Trouble 7. When the inkjet printer loads the print driver online, a pop-up prompt from the computer system tells us that the inkjet printer device cannot be found. When carefully checking the printing power supply and the connection, it is found that they are normal, and the author has also replaced the new print data. The printer driver used is also downloaded from the official website. When the author tried to skip the printer check operation and load the print driver, the inkjet printer could not print normally and prompted that there was an unknown error.
When encountering the above inkjet printer failure, we may first check the printer driver carefully, enter its property setting interface to see if the print port setting is consistent with the actual print port used. In general, we must carefully check the default printer port of the computer, and we must change it as soon as the port mismatch is found. Moreover, there may be program conflicts during the installation of inkjet printers. For example, when the HP brand inkjet and the Epson brand inkjet are installed on the same computer at the same time, it is easy to appear incompatible with each other. We may try to connect the faulty printer directly to other computers in order to determine whether the current fault is caused by the printer hardware or software.
Trouble 8. Sometimes we will find that the inkjet printer does not emit ink during the work process, and when cleaning the print head, the ink lamp and the paper feed lamp in the control panel will stay on together, and other signal lights are in Not bright. When I pressed the paper feed lamp and ink lamp in the control panel by hand, none of them responded.
Unfortunately, when encountering such a malfunction, it is likely that the circuit part of the nozzle of the inkjet printer has a problem, or the head cable is accidentally disconnected, so that the electrical signal of the print head cannot be transmitted normally. Generally speaking, this kind of printing fault is relatively complicated, and it is often impossible to solve the problem through ordinary inspection, so we need to send it to a professional maintenance center in time to solve it.
