1. The printing machine is awaiting maintenance. This refers to the maintenance performed while the machine is in a stationary state. Key points include: regular oil changes, filter cleaning, and periodic machine accuracy checks; enhancing the maintenance of critical components. Components such as bearings, gears, and rollers are crucial parts of the printing machine, and their precision variations affect print quality. The quality of the springs also determines the level of precision, with a sensitive elasticity being crucial. Damping and irreversible plastic deformation are detrimental to the springs' operation. Machine maintenance should adapt to environmental changes, and structures that are不利于 maintenance should be improved without affecting normal operation.

2. Printing Dynamics Maintenance. Maintenance on the printing machine is conducted while it is in motion. Static machine maintenance is a prerequisite for dynamic maintenance, and the dynamic operation of the machine can also reflect the level of static maintenance. Dynamic machine maintenance is quite important. Key points include: machine readiness checks, lubrication status, and impacts during operation.
