Eliminating the prompt of "the printer is not installed properly"
the fault of the printer is really strange. We have clearly installed the printer correctly, but when performing the printing operation, the system sometimes still sends us a fault prompt, "the printer is not installed properly, and we cannot print documents". This is not true. The author recently encountered this strange printing failure when printing documents; When the author opens the word target document and clicks the "file"/"print" command in its interface, the printer does not respond after a few seconds, and the system soon pops up a fault prompt of "the printer is not installed and cannot print the document"
I thought this kind of fault was easy to solve, that is, the printer was not installed well, so I deleted it and reinstalled it to solve the problem; The author thought of doing it, quickly open the printer list window, delete the previously installed printer, and then double-click the "Add Printer" icon to reinstall the printer driver. However, it is surprising that when the author executes the "print" command again, the newly installed printer can't respond to the author's print command, and the same fault prompt still appears in the system
since the printer driver is reinstalled, the system still has the same printing fault, is it because the computer and printer are not connected well? In order to ensure that the printer can be reliably connected with the computer, the author had to pull out all the connecting cables, and then re connect them. The screws were tightened at the cable joint to ensure that the cables can be stably and reliably connected with the printer and the computer, but the author's efforts were still ineffective. Is there a hardware problem with the printer itself
in order to check the working state of the printer, the author specially moved the printer to another location and connected it with other computers that work normally. After connecting it, the printer driver was installed in the correct way. As a result, the author found that the printer could print documents immediately after changing the working environment. Here, the author preliminarily concluded that the hardware quality of the printer was no problem. Next, the author found a printer that has been working normally and tried it by connecting it to the previous computer. After installing the print driver and trying to execute the print command, the system unexpectedly also appeared a fault prompt of "the printer is not installed and cannot print documents". Obviously, this print failure is caused by the computer system itself
what on earth is the system that causes such a failure of the printer? Is it because the BIOS parameters of the system are not set properly, or other reasons? The author first tried to reset the printing parameters in the computer system. 2. Function differentiation and enter the BIOS system to modify some options of the printer, but the system that has modified the printing parameters still has the same fault prompt
at a loss, the author had to reinstall the computer system. Because the system had been backed up previously, the author chose the ghost recovery method to quickly complete the system reinstallation operation. After the recovery operation was successful, the author carefully reinstalled the printer into the computer, and then tried to print. As a result, the printer worked very well this time; After comparison, it is found that the printing fault is indeed caused by the computer system itself. So far, the author believes that the fault should be solved, so he often breathed a sigh of relief. But no one thought that in a few days, when the author was printing again, the computer system popped up the same fault prompt as the above. It seemed that the printing fault had not been really solved
as the author has previously verified that the printer itself is no problem, and the printing setting of the computer system is no problem, so the author naturally focuses on the virus this time. After all, once the virus occurs, any strange fault may occur; But on second thought, the author believes that the failure is not caused by a virus, because the author has installed the latest version of rising anti-virus software in the computer, and also regularly updates the virus database on the computer. There should be no virus in the system
when the author was helpless, Rising antivirus software suddenly popped up a prompt, telling the author that the current computer system may have viruses or malicious code intrusion. The author clicked the "OK" button in the prompt interface to isolate the found viruses. Next, the author restarted the computer system. When the screen appeared on the desktop of windows system, another information prompt appeared in front of the author, which told the author that there was a reference in the system file "I"; According to this prompt, the author opened the system resource manager window, found the system file "I" in it, and then opened it with a text program such as Notepad. As a result, it was found that there were only a few lines in the file, and the author also found that the content of the last line was the reason why the error prompt popped up when the system was started. Is it possible that the system file "I" was damaged by malicious code or virus programs during the operation of the wire twist tester
in order to check whether the contents of the "I" file are normal, the author came to a computer that was not on the computer. After opening the "I" file in the computer, the author found that it actually contains many lines of content. How many lines should the "I" system file contain? In order to find out the real function of the "I" file, the author had to search the introduction information of the file, and found that the "I" system file should contain the configuration information of relevant Windows systems, such as printer installation and setting information, system color setting information, font installation information, desktop setting information such as file icons and wallpapers, In addition, many applications will add the configuration command line containing the corresponding program to the system file, and the content of the file will often increase with the increase of applications; More importantly, when we restart the computer system, the "I" file will be automatically transferred into the system memory by windows with the startup of the system. Here, I finally understand why the system will pop up the prompt that the printer is not installed: when I surf on the computer, I was accidentally infected by a network virus, so many Trojans or malicious code invaded the computer system, and after these viruses or malicious code invaded the computer, they will forcibly rewrite the contents of the "I" system file and automatically delete many important data in the file, At the same time, it will also load some destructive programs when the system starts, causing some devices in the computer (including printers) to fail to work normally. Although anti-virus software has been installed in the computer system, these anti-virus programs often can only detect malicious code files, and are unable to kill these malicious code files. Welcome to call and consult the malicious code files
after finding the cause of the failure, the author quickly updated the Rising antivirus software again and upgraded it to the latest version; Then disconnect the network connection of the computer, and use the latest version of anti-virus software to comprehensively check every corner of the system where Jinan Hongjun Experimental Machine Manufacturing Co., Ltd. provides you with 7 * 24 hours of perfect after-sales service. After the virus was killed, the author worried that the virus would modify the "I" file at will in the future. Therefore, he entered the system resource manager window, where he modified the attribute information of the "I" file and set it to the "read-only" state. Of course, we need to remind you that when you need to add other hardware devices to the computer in the future, you must modify the "read-only" state of the "I" file in time, otherwise the newly added hardware configuration information cannot be saved to the "I" file. After finishing the above work, the author restarted the computer system again. This time, there was no prompt in the system, and the printer can work normally at this time
