Fourth, machine fault detection

At present, most copiers are equipped with a color liquid crystal display panel , and a paper jam self-test function , once a component failure or damage to the machine , can alphanumeric told the operator. More common is the fault code , such as NP series copier fault code "E0 ~ E8 , etc. , Ricoh series places " U " plus the number of code that appeared denote the printed circuit boards, sensors, switches , connectors , etc. abnormal working conditions , need to be adjusted or replaced. as a user of the machine, see these fault codes should be immediately shut down, turn off the power, service personnel if the repairs yourself , then you must find the same model used by the machine maintenance manual or service manual, contents fault code found in the book represented , and then check the corresponding components , circuit boards or electronic components.

 

Second, the common "common" failure overhaul

 

Since many types and models copiers , copiers each factory production varies, even different models of copiers produce the same manufacturer is not exactly the same. Thus the use of the fault phenomena that appear there are some differences here only common, general common faults and their causes and remedies to be introduced .

Failure enumerated herein , for a variety of copiers not always the case, even if the same fault in the different types of machines , its causes may not be the same . So here is more important is to provide methods and ideas . ( Just find some fault causes exclusion method that is known , so these troubleshooting method will not repeat them. )

First, the impact of a copy of the reasons for the exclusion of quality failures

Copies of poor quality is the most frequently occurring faults copiers , such failures can total more than 60% failure rate , the following are specific fault repair and troubleshooting .
