The following is the common faults and solution for the electric eraser, which is the experience of producing the suguang electric eraser for these years that we summarize. If there is any deficiency, welcome you to supplement.
- Why not run after install the battery?
Please check whether the battery is installed in a reversed direction, or is installed with the non-electric quantity battery. Some brands’ electric erasers would reverse when the battery is installed in a reversed direction, but some other brands will not run. This question can be settled by self.
Is it dropped? If so, the wiring or the battery probably drops, leading to the bad contact. The users can try an inspection to see if it works. If can’t repair it, please exchange it or keep in repair in the purchase shop.
Does it have water penetration? If so, the problem can’t be settled by self because the motor can’t run when having water penetration, so the users only exchange it in the purchase shop or keep in repair.
If it is still not work after you install the new battery and check all the questions, the biggest possibility is that the motor is bad or has bad contact, please exchange it or keep in repair in the purchase shop.
- Why does the electric eraser’s RPM drop, and why does the erasing not have the strength? Why does it not run?
The battery voltage will be reduced after using for a period of time, while the eraser’s erasing strength is also reduced. Please replace a new battery timely (to protect the environment, please do not throw away battery at will). Actually, everybody can use the rechargeable battery, but must purchase the rechargeable battery and battery charger by self.
- Why is the battery or the electric eraser hot?
The reason probably is the combined use of new and old batteries or the fault of the battery, or the short-circuits of the motor or other zones, and you must take out the battery immediately under this situation, please exchange it or keep in repair in the purchase shop.
- Why does the electric eraser’s sound increase?
After using for a period of time, the sound of some brands’ electric erasers will increase, this phenomenon is normal, because now the prices are very irregular,
To reduce the cost, some manufacturers use the single bearing motor – there is a plastic lid in the motor’s top plate without bearing. If the time of using this kind of motor is longer, and the times of using are more, the border and sound will be bigger due to the high-speed rub between the electricity engine shaft and top plate, thus it will cause the quality to become bad. For the micro motor with duplex bearings, the sound will be increased a little after using for a long time, but this is the normal phenomenon, because now the question regarding the sound changing of the micro motor is a difficult problem in the industry. Everybody does not buy too cheap electric erasers, because it would reduce the users’ experience.
- Why does the shaking degree of the electric eraser’s center is increased?
The first situation: the shaking degree of the electric eraser’s center is high when purchasing it,and while it is probably because the degree of hardness for the eraser core is not good. The degree of hardness for the eraser core plays a very essential role in influencing user experience.
The second situation is: after using for a period of time, the shaking degree of the electric eraser’s center under some brands will increase, this phenomenon is not normal. Because now the price is very irregular, and some manufacturers want to reduce the cost, they will use the single bearing motor (there is a plastic lid on the motor’s top plate without bearing). If the time of using this kind of motor is longer, and the times of using are more, the border will be bigger due to the high-speed rub between the motor shaft and top plate, thus it will not only cause the sound to be increased, but also cause the shaking degree of eraser core to be bigger. The erasing is not accurate; the users would have a not good experience. Therefore, the truth “The cheap buyer takes bad meat” never changes.
- Why does the eraser core stick pencils ash?
The pencils ash will stick on the eraser core in the process of use, and while it is because the suppliers of the eraser core use inferior materials. There are several kinds of TPR materials, which are from China mainland and import. This situation will seriously affect the use experience, and the degree of erasing for the eraser core will be very bad. Users will possibly be unable to erase the wrong characters or smear the paper, and unable to express the idea in the sketch.
