Location and Frequency

Cleaning should be performed approximately every 10,000 [fi-7800]/12,000 [fi-7900] sheets scanned. Note that this guideline varies depending on the types of documents you scan. For instance, it may be necessary to clean the scanner more frequently when you scan documents on which the toner is not sufficiently fused.
