Power Supply Units PSUs maintenance methods

Step 1 Do not switch the machine frequently
Some of them are always shut down and restarted because of small problems. This kind of habit is very bad, which will greatly damage the computer hardware. It is best to enable hibernation if you don’t use it for a short time. Don’t drag the vibrating computer while the computer is still in use, and you can’t plug in the hardware accessories. These practices will greatly damage the computer.

Step 2 should be turned on frequently
If the computer has been idle for a long time, if it is in the summer, if the air is wet, the host is prone to short circuit caused by the tide. It is best to turn it on every day for 10 minutes a day. When it rains and thunder, be sure to turn off the computer and put all the The power plug is pulled out.

Step 3, don’t pay attention to heat dissipation
Long-term operation of the computer heat accumulation, long-term operation of the computer will slow down or crash, summer should pay attention to indoor ventilation, CPU fans to buy a better point. If it is too hot, it is best to open the cover of the case to make it easier to dissipate heat. For the problem of antifreeze, if the computer is too cold in winter, it will cause the problem of opening and not turning on.

Step 4 Pay attention to dust
Dust damage to the computer is also relatively large, usually do not open the computer case cover, when the computer is not in use, the computer host is covered with a cloth to prevent dust from entering the computer and causing malfunction.

Step 5 Try to use a three-hole socket
It is best to use a 3-hole socket to prevent static electricity from collecting on the computer. This reduces the occurrence of static electricity. If you feel an electrostatic shock on the chassis, connect the chassis to a copper wire and ground the other end.

Step 6: Turn on the peripherals and then turn on the host when booting.
The correct boot sequence is to open the peripherals and then turn on the host, such as print connection, audio, display, etc. Turn off the host first when shutting down.

Step 7: The computer cannot be loaded and unloaded during daily use.
When loading and unloading software, you should check to see if it is the software that comes with the original system. Removing the software that comes with the system can sometimes cause major problems with the use of the computer.

Step 8 prohibits magnetic objects from being placed around the display
Such as mobile phones, audio, etc., do not be placed next to the display, so as to avoid magnetic interference.

Step 9 The computer needs to carry out dust removal maintenance for half a year.
It is best to do a dust removal every few months. If you don’t know what to do, you can ask a professional maintenance person how to remove dust from the chassis to avoid damage to hardware or electric shock.

Step 10 The computer cannot be used overnight.
The computer is not used all night, which will cause the computer to accumulate too much heat, and all kinds of hardware will wear out. The long-term use will reduce the life of the computer, and the computer will also have radiation. It is not good for the body.

Thermal transfer barcode printer head maintenance knowledge

In the maintenance mode of the thermal transfer barcode printer head, the quality of the print medium is particularly important. In order to save money, some enterprise users use low-cost thermal paper or ribbon, but the price is not always good, and the inferior print media will speed up the damage of the print head. Therefore, enterprise users should give priority to brand-printing consumables with the smooth surface and excellent texture to prolong the service life and print quality of the print head. To get the best out of it, clean the bar code printhead every time you use a roll of ribbon or a roll of thermal paper. Be careful to prevent hard objects from scratching the bar code printhead when cleaning the bar code printhead, and use a grounded metal strap or anti-static pad to prevent static damage to the bar code printhead.

When there are inconsistencies in the printout of blank dots/lines in the bar code or graphics, there may be dirt on the printhead that needs cleaning. For best results, the thermal transfer barcode printhead should be cleaned regularly before loading a new roll of ribbon tape, hot transfer printer media, or printing over 150 meters of continuous or folded print media. It is not required to turn off the power when cleaning the print head.

In addition, business users should pay special attention to the use of “professional cleaning solvents” or choose to use “printer cleaning film” to clean and maintain the print head to avoid unnecessary damage caused by dust contamination on the surface of the print head. Thermal Transfer Barcode Printhead Film is a special film that removes dirt deposits from the printhead without damaging the printhead. There are many advantages to using a rescue printhead to clean the film: in addition to extending the life of the printhead, it also reduces the downtime required for maintenance and saves the cost of replacing the printhead. Therefore, it is an economical, convenient and quick way to remove dirt and dirt without the need to remove the print head.
