serious damage to the printer in the circuit board or mechanical parts, resulting in printer damage. Generally speaking, the liquid level of the outer cartridge should be controlled slightly below the nozzle part, but must be lower than the top of the inside cartridge. The optimal level of liquid, also need to be used in the adjustment to determine. In addition, the waste ink pad is full, printing nozzle plug or the word car movement will also cause the printer does not work. applicable to th

When you solve a user's PC fault, do not forget to use a multimeter to test the power supply. Learn some simple and easy-to-use skills to help you eliminate the possibility of power failure. It may not seem obvious, but more than 1/4 of PC problems are related to power problems to some extent. You may think that if there is
A simple method to increase AC-DC power supply power loss and keep timeAbstract: In some special applications, the conventional AC-DC switching power supply power loss holding time can not meet the requirements, and ultra-long power supply holding time switch power supply in
One, skillfully set the power off button The power button under the Start menu is free to set, we can right-click on the Start button, select Properties to pull up the menu on the right, and then set the Drop-down menu in power button action, and click OK to finish. Small series I usually restart the computer more often, so, set to restart the key, convenient a lot. Digression: There are many other features under this setting, and friends can take ti
UPS uninterruptible power supply has become the current data center of the important equipment, understanding UPS work Mode UPS is a basis for daily maintenance. The following according to the different electrical environment, said UPS uninterruptible Power supply Work mode problem. First, the normal operation of the mode of work Under normal circumstances, U
Recently I have read several posts about power switching, so I will share with you the power switching circuit used in one of my projects. Thank you.Features:1. Supports touch switch and self-locking Switch2. Support automatic power-on of external power supply (which can be achieved by welding d17)3. Support for standby power output4. The external power supply and lithium-ion power
What is a frequency conversion power supply?The AC Variable-frequency power supply technology has been widely used in developed countries. Its principle is to convert the AC power in the mains supply through AC → DC → AC, and output it as a pure sine wave, the output frequen
In the past, on-site cabling was very simple. The sensor can be either power-supply or passive. The power supply type requires 2, 3, or 4 cables, and the passive type requires only 2 cables. At the same time, the sensors are both analog-type and support 12, 24, 36, 48VDC, or 110, 220VAC voltages. The field controller provides power for each sensor, and each sensor is connected to its related controller. Bec
Troubleshooting of starting and welding by hard disk power supply interface The author of a computer post more smoothly, but the system does not detect the hard drive, and can not enter the system, the author began to suspect that the system file damage. So ready to reload the system, but still can not detect the hard drive, so the decision may be hard disk hardware problems, such as hard disk Power inter
supply interface. The power supply interface is a major factor in limiting future upgrades, so users who cannot one-step are best prepared to provide a broad posterior approach to their power supply. 4, to ensure that the line loss is small, the line diameter must be 18th
5G technology, the power consumption and cost problems of far-reaching optical power supply are enough for it to drink a pot, 5g a pot 5G is getting closer and closer, but not all places have it, and it will not be abrupt. The first version that comes to people's eyes is not the fastest version of the technology. In reality, 5G is the first to show in

"Fault phenomenon" a computer recently connected to the power on its own boot, sometimes inexplicably on the boot. "Failure analysis and processing" causes this kind of failure may have the following: (1) First check whether the computer in the BIOS setup will be timed to boot function set to "Enabled", so that the computer in the set time automatically boot. (2) Again check whether the computer in the BIOS setup item to open the function of the call
The resonator is formed between the power supply and the large plane of the formation. When the high-speed digital signal passes through, it is like a speedboat setting up a wave on the lake, and the voltage between the power supply and the ground fluctuates. Since it is a r
