How to fix fuser error on printer? Copier fuser unit failure
The copier fuser unit is one of the core components of the copier. Its function is to fix the toner on the copy paper to form a clear image on the paper surface. If there is a failure, it will directly affect the printing quality of the copy paper and may even cause the copy machine to fail to work normally. The following are possible failures of the copier fuser unit and their solutions:
- 1. The fuser unit cannot be heated
If the fuser unit cannot be heated, the toner on the copy paper cannot be fixed, resulting in blurred image printed. This may be caused by faulty fuser heating plate, poor wire contact or failure of the thermal switch.
Solution:
Check whether the fuser unit heating plate is working properly, check whether the fuser wire contact is loose or fall off, and if so, reconnect the fuser wire. If the thermal switch fails, the thermal switch needs to be replaced.
- 2. Overheating of the fuser unit
If the fuser unit is overheated, it will cause problems such as drying, curling or deformation of the copy paper, and may also cause toner to stick to the fuser unit.
Solution:
Adjust the temperature of the fuser unit control board, reduce the temperature setting, shorten the use time of the copier, and avoid long-term continuous copying.
- 3. Fuser unit tires are worn or loose
Wearing or loose tires will cause the fuser unit to fail to work properly and the toner cannot be fixed on copy paper, causing a lot of waste of toner or contaminating the device.
Solution:
Replace the fuser unit tire or adjust the tire position to ensure that the tire contact is flat.
- 4. Fuser unit deterioration or aging
If the fuser unit deteriorates or ages after use for a period of time, the fixing cover will be slightly raised, causing the toner to be applied in the copy and cannot be adhered to the paper.
Solution:
Replace the fuser cover or replace the fuser unit.
In short, maintaining and maintaining the fuser unit is an important task to ensure the normal operation of the copier. Only by timely repairing and maintaining the fuser unit can the efficient work of the copier be ensured and the service life of the copier can be extended.
