G3传真机的调整、维护是其正确使用的一个重要方面,它关系到机器能否高质量地接收、复制图像。在电气方面,由于G3传真机采用大规模集成电路,因而性能稳定,一般无需调整。但是一旦发生故障,就必须更换整块集成电路芯片,甚至整块线路板。在机械方面(包括光学系统),由于G3传真机加工精密,在出厂前,各部件都已做好了必要的调整工作,因而一般也无需调整。但是,如果在偶然的情况下破坏了已调好的状态,或者在更换相应部件后,就必须重新进行调整。另外,有些器件如荧光灯管、记录头、记录纸等寿命有限, The adjustment and maintenance of the G3 fax machine is an important aspect of its proper use. It relates to whether the machine can receive and copy images with high quality. On the electrical side, since G3 fax machines use large scale integrated circuits, their performance is stable and generally do not need to be adjusted. However, in the event of a failure, it is necessary to replace the monolithic integrated circuit chip or even the entire circuit board. On the mechanical side (including the optical system), since the G3 facsimile machines are precision machined, all the necessary adjustments have been made to the parts before they leave the factory, so there is generally no need to adjust them. However, if accidental conditions undermine the well-adjusted state, or after the replacement of the corresponding components, it must be re-adjusted. In addition, some devices such as fluorescent tubes, recording heads, recording paper and other life is limited,
