Machine Faults and Solutions

By | May 15, 2015

The real skill involved in operating machinery, isn’t necessarily simply setting up and running the machine; the real issue is knowing what to do when there are problems. With printing machinery, problems are not always catastrophic events, sometimes the slightest adjustment or malfunction can cause a fault with the quality of the product. It is therefore important to understand the workings and principles of the machinery you operate, and adopt a methodical approach to problem solving.

This lesson will analyse a methodical approach to problem solving, starting from the information gathering process, to analyzing and test that information to come up with a viable solution. This session will also explain the importance of using correct tools, equipment and parts when engaging in maintenance activities.

Read through the presentation then answer the questions below to test your knowledge. This lesson should take approximately 30 minutes, however you might want to take longer research some of the individual topics. You can revisit this lesson at any time.

1. How might an operator notice a developing fault whilst a machine is running?


2. Which of his or her senses can an operator use to notice the development of faults whilst a machine is running?


3. What type of machine fault is it when rubber rollers start to perish?


4. What type of fault is it when a substrate creases as it passes over an impression cylinder?


5. What type of fault is it when the substrate or material has been loaded into the machine upside down/the wrong way around?


6. What tool should be used to measure the diameter of roller bearings?
