* Paper feed section roller life
Each roller life is 200K. When, therefore, a certain unit is used intensively, the life will be expired before the maintenance cycle.
Since, however, sheets of different sizes are used with different paper feed trays actually, it is quite rare that the roller replacement is
required before the maintenance cycle.
If a certain size of paper is intensively used, explain the user to use different paper feed trays for that size as far as possible.
When servicing, always check the use frequency of each paper feed tray, and replace the roller according to necessity.
When cleaning the roller, it is recommendable to use wet cloth.
The wear level is greater in the sequence of the separation roller, the paper feed roller, and the paper pickup roller.
