Printing Press Troubleshooting

Various problems often occur during the use of printing machines. Parts are often damaged and electrical faults occur frequently. Some people say that the machine is too old. The fact that the machine is old is certainly an objective reason, but won't new machines break down? In some printing plants, new machines have more faults than old machines. Objectively speaking, the usage and failure rate of the machine include the following factors: the manufacturing quality of the machine, installation and debugging, maintenance status, reasonable operation, and most importantly, the quality of maintenance. The quality of a machine exists objectively when it leaves the factory. Whether it is a new machine or an old machine, installation and debugging are the first steps.
Generally, new machines are installed and debugged before leaving the factory, undergo quality inspection, and are then packaged and transported separately. It's not just a matter of leveling and proper installation, there's also an issue of inspection and correction. This is especially true for old machines. As for maintenance and use, I won't go into details. I just want to talk about the quality of maintenance:
Maintenance is not a simple disassembly and assembly. It is not only necessary to find the cause of the failure, but also to find other problems caused by it.
Printing machines have strict time coordination, assembly tolerances and adjustment values. Busy disassembly and excessive adjustment are the main reasons for accelerated wear and failure of the machine.
The procurement and processing quality of spare parts does not necessarily require the use of original parts for all parts and electrical components. The cost of original parts is high and the procurement cycle is long. Unless there are special or critical spare parts, most other parts and electrical components can be substituted. , as long as you understand the parts processing technology and component characteristics.
In addition to natural damage to the machine, circuit failures are mainly hidden failures derived from careless disassembly and installation or failure to find the machine and human factors that caused the circuit failure.
