Eight common symptoms and solutions for inkjet printers
ã€Office Partner Information Center】Inkjet printers have been plagued with bizarre malfunctions for a long time for us to “serviceâ€; in order to ensure that ink jet printers can work efficiently, many people are interested in frequent occurrences. The ink-jet printing faults and the troubleshooting process were summarized so that they could be prepared in the future in the event of an identical failure, and were quickly eliminated in a targeted manner.
Fault I. In the most recent period, the inkjet printer in the office of the unit performed an automatic cleaning operation almost every day. Is this phenomenon normal? 
Under normal circumstances, inkjet printers generally do not clean the nozzles frequently. If we unfortunately encounter this phenomenon, it is likely that the control circuit of the inkjet printer has failed. The automatic cleaning nozzle operation is performed according to the ink jet printer program settings and actual use conditions. If the cleaning nozzle operation frequently occurs or continuously performs the cleaning operation, there is a possibility that the inkjet printer controls the nozzles to be disordered. Phenomenon, at this time we must promptly sent to a professional maintenance station to repair. Considering that inkjet printers belong to the more sophisticated electromechanical integration equipment, the inkjet printer motherboard control chip can precisely perform the paper feeding operation, paper feeding operation, paper output operation, and print head moving operation under the cooperation of various precision mechanical parts. Accurately print the target material on the corresponding print paper. The print heads frequently encountered cleaning problems, not necessarily the print head itself, may also be related to the printing ink system, ink system and even print control circuit failure, these factors may lead to print The showerhead undergoes frequent cleaning operations.
Fault 2. After the inkjet printer uses the continuous ink supply mode, the print head is damaged. The inkjet printer heads with different models and types are used for replacement. Will this replacement method be used?
As we all know, the nozzle is one of the most precise and important components in inkjet printer equipment. In addition to the strict process flow and production environment in the manufacturing process, it is also responsible for storage, transportation, installation, and replacement. The link has strict requirements. Any non-standard and improper operation may cause serious damage to the quality of the print heads or even direct discarded. Although in many types of printers, inkjet printers of the same series of brands may encounter print heads common to each other, GM also requires manual replacement and installation, and this operation often requires high precision. Therefore, we must not use other types of inkjet print heads at will to replace them to avoid damaging the output nozzles of inkjet printers, thus causing unnecessary economic losses to ourselves.
Fault 3. When using an inkjet printer to print out black and white documents, we often find out that the printed pages contain colored horizontal lines, and these horizontal lines appear irregularly.
When we encounter phenomena such as color misregistration, ink leakage, and plugging, or when using an inkjet printer to print a black-and-white document that encounters a colored horizontal line, we may be able to determine that the above phenomenon is caused by damage to the inkjet print head. Under normal circumstances, there are many causes of ink jet print head damage, but can be roughly divided into hard failures and soft failures. From the above description of the fault, we think that the inkjet print head should be physically damaged, so we must promptly send the inkjet printer to a designated maintenance point to replace the print head. If the print cartridge is integrated with the print head, we should not hesitate to replace the entire print cartridge.
Fault 4, an inkjet printer can print a single sheet of paper, but at the same time print out more than 2 pieces of content will automatically stop printing, while the inkjet printer power light will be in a state of flashing, when the print user to disconnect printing When the power is turned on again, the print head emits a weird sound. Although the ink jet printer can be reset normally, the above problems will occur repeatedly.
Once the above-mentioned failure phenomenon is encountered, most of the foreign objects accidentally enter the inkjet printer or the mechanical parts of some printers have worn out and aging phenomenon, which causes the printer carriage to fail to run smoothly, and may even cause the printer carriage to be jammed. dead. Therefore, in order to extend the useful life of the printer's mechanical parts as much as possible, we suggest that you should try to print materials with a slightly better print quality, and be sure to close the lid of the inkjet printer when using and placing the inkjet printer. , to avoid printing paper, air dust and other effects on the printer's mechanical parts. If some of the print components wear out and the print carriage does not function properly, we should send the inkjet printer to a designated service station for repair.
Fault 5. When the inkjet printer starts the self-test, strange sounds are generated from the belt and motor of the carriage. And this phenomenon will happen every time the printer is started, but the ink jet printer is all normal during the process of printing materials. Is this phenomenon normal?
In fact, this is an abnormal phenomenon. Although the inkjet printer may emit sound during operation, there should be no abnormal sound between the belt and the motor of the printer carriage. Once accidentally encountered the above phenomenon, we should first carefully check whether there is any foreign matter inadvertently into the inkjet printer. If foreign matter is inadvertently entered, it will often cause an increase in the operating load of the ink jet printer's car and related components such as the motor, or scrape the car belt. At this time, we may carefully refer to the printer's built-in installation manual to carefully remove the foreign body. If you find that the foreign matter in the inkjet printer has entered a deep position or stuck, we must ask a professional maintenance staff to repair. We need to remind our friends that the reason why such an ink jet printer may have such a printing failure is probably due to the fact that we use a continuous ink supply system with a relatively low quality and a compatible ink cartridge, which can easily cause an ink leakage accident and leak out. The printing ink will increase the running resistance of the ink jet printer mechanical parts, and the extra piping of the ink jet printer using the continuous ink supply system will also impose an additional burden on the carriage and the print motor.
Fault 6. Inkjet printers have discontinuous color bars during the printing process. When playing the test page, it was found that there was a problem with the distribution of the blue and light blue patches, the location was incorrect, and the problematic hole was not yet determined.
There are two possible problems with this type of failure. First, there is a problem with the ink cartridge, or there is a shortage of ink or a non-genuine cartridge; second, it may be that the printer is used for a long time, and components such as the pump and the pump attachment are worn, resulting in insufficient sealing. The first troubleshooting method is to check if the ink cartridges are installed correctly. Users can install the ink cartridges according to the "User Manual" and the cartridge installation order of the printer body identification. When the nozzle inspection sample breaks, it can perform 1 or 2 cleaning operations (the cleaning operation will consume a certain amount of ink, so we recommend that you do not perform the cleaning operation more than 3 times, in addition to improve the cleaning efficiency, you can also try at each The printer is allowed to stand for a while between cleaning operations.) If the cleaning operation is invalid, it can only be sent to the service center for repair.
Fault 7. When the inkjet printer loads the print driver online, the computer system pops up a message telling us that we cannot find the inkjet printer device. When we carefully check the power supply and the connection, we find that they are all normal. At the same time, the author has also replaced the new print data. On the line, the printer driver used is also downloaded from the official website. When the author tried to skip the printer check operation and loaded the print driver, the inkjet printer could not print normally and suggested that there was an unknown error.
When encountering the above-mentioned inkjet printer failure, we may wish to carefully check the printer driver, enter its property setting interface to see if the print port setting is consistent with the actual print port. In general, the computer's default printer port must be carefully reviewed and must be changed immediately if port mismatch is detected. In addition, during the installation process of the inkjet printer, program conflict may occur. For example, when HP brand jetting and Epson branding are installed on the same computer at the same time, incompatible phenomena may occur. We may try to connect the faulty printer directly to other computers to determine if the current failure is caused by the printer hardware or software.
Fault VIII. Sometimes we will find that the ink jet printer does not print out ink during the working process, and when the print head is cleaned, the ink lamp and the feed lamp in the control panel are in a long light state together with other signal lights. Off state. When they pressed the feed lamp and the ink lamp in the control panel by hand, they did not respond.
Unfortunately, when this kind of failure phenomenon is encountered, it is very likely that there is a problem in the circuit part of the ink jet printer head, or the head cable is accidentally disconnected, so that the print head electrical signal cannot be properly transmitted. In general, this type of printing failure is relatively complicated. It is often impossible to solve the problem through ordinary inspections. Therefore, we need to promptly send it to a professional maintenance center to solve it.
