2.3.7 BLANK SHEET DETECTION

When the machine scans the document for transmission, it counts the black pixels.
If the number of black pixels is below a certain threshold, the machine displays an
error message (BLANK DOCUMENT).

Immediate transmission

When the machine detects one or more blank pages, the LCD displays an error
message for 20 seconds after transmission.

Memory transmission

When the machine detects one or more blank pages, the LCD displays an error
message for 20 seconds after completing memory storage.

Cross Reference
Section 4.5 Service RAM Address

800858 Error display condition

The setting of this RAM address determines when the machine displays the “blank
paper detected” error message.

01H: If the first page is blank (default setting)

02H: If all the pages are blank

03H: If at least one of the pages is blank
