CTP often encounters some faults during operation and needs to be shut down to check. In this case, if the processing steps are not correct, it is easy to cause harm to the safety of the operating staff and the equipment itself. Strictly following the troubleshooting steps can not only guarantee Personal safety can also guarantee the service life of the machine. 1. Security
Lipsticks are intended to add color and texture to the Lips and often come in a wide range of colors, as well as finishes such as matte, satin and lustre. Lip stains have a water or gel base and may contain alcohol to help the product stay on the lips. The idea behind lip stains is to temporarily saturate the lips with a dye. Usually designed to be waterproof, the product may come with an applicator brush, rollerball, or be applied with a finger.
Lipstick is a cosmetic containing pigments, oils, waxes, and emolliemt that apply color, texture, and protection to the lips. Many colors and types of lipstick exist. As with most other types of makeup, lipstick is typically, but not exclusively, worn by women. The use of lipstick dates back to medieval times.

(1) How often does the problem occur?
(2) Will the problem occur repeatedly in the same imaging cycle?
(3) What are the error messages?
(4) Does the problem occur continuously or intermittently?
(5) When did the problem occur?
(6) Do other problems occur at the same time?
(7) Was there a new installation or setting change when the problem occurred? There is a clear conclusion, and then use the following method to further operate. 
CTP equipment often encounters troubleshooting steps
The laser from the laser hair exposed by CTP is invisible to human Eyes, but the high-power invisible laser causes serious damage to human skin and eyes. Therefore, each shell of the CTP is equipped with a safety protection lock system. Once opened, it will automatically alarm to prevent the operator from being injured by high-power invisible lasers and moving mechanical devices. If the outer cover of the machine is suddenly opened during the exposure of CTP, the safety lock system will act as follows: (1) stop the work of all mechanical components; (2) stop the work of the laser system.
But the mechanical part of CTP does not stop working, please follow the steps below: (1) Turn off the power of CTP; (2) Replace the failed cover; (3) Contact the engineer immediately, do not try to stop or touch the inside of CTP Machine parts.
Safety is the highest priority. Before repair work is carried out, unsafe factors must be eliminated or the equipment must be controlled to operate within a safe range.
2. Describe the symptoms of the problem
Collect some detailed and correct symptom information to ensure that there are sufficient resources to solve the problem before repairing the machine. You should use your own system or service knowledge to record the source of the problem. In addition, you can ask yourself some general symptom questions. E.g:
3. Reproduce the problem
If such symptoms often occur, you can better fix the symptoms, narrow down the scope, and determine the problem when repairing. Generally, when you can see the symptoms, the problem will be easier to solve. When the problem is in front of you, you can directly hit the core of the problem, so reproducing the problem is a very important part of the repair process.
4. Analyze the reason
In order to avoid spending too much time and money on wrong judgment, the following possible failure points should always be covered when dealing with problems: (1) problems during operation; (2) problems with the built-in firmware of the machine; (3) mechanical problems ; (4) Air pressure.
5. Reduce the fault scope
First of all, check the machine for some small problems or problems that can be seen at a glance (such as loose signal lines, etc.); second, use your system knowledge and effective technical information to narrow down the failure factors to the minimum range; in addition, intermittent The problem may make your test invalid, but you need to continue to try many times, and you must go back to the original phenomenon and repeat the test, so as to accurately judge the machine failure.
6. Repair or replace parts
Use the correct tools and appropriate procedures to deal with the damaged circuits and internal software. At the same time, you should pay attention to when disassembling the related parts, you must ensure that you have enough technical strength to assemble them again. When replacing unfamiliar parts, you need to follow the relevant procedures, and do n’t forget to bring a safety electrostatic belt to protect the safety of the device. If there is enough technical strength to replace one of the parts on the circuit, it must be completed according to the previous parameters and related reliability.
7. Test results
When all systems and components are turned on, try to solve some other problems. If the problem has been solved and the machine has been properly repaired, it is necessary to avoid other problems at this time. When you use a better test tool, all test results will be displayed, and your repair work is basically completed.
8. Prevent the problem from happening again
To prevent the recurrence of the same accident, we need to keep testing and complete the scheduled equipment maintenance plan. The first condition to prevent the recurrence of failures is to completely resolve these failures. If possible, you can guide the operator to do some related maintenance work to prevent the recurrence of the failure to the greatest extent.
9. Record the repair process
When a fault is eliminated, it is best to record all actions and mark the parts that can be changed as appropriate. Through the recorded information, we can see the process of handling the problem, so that when a similar fault occurs again, we can easily find a solution from the record.
