Improved Tolerance To Black Lines When Paper Passes Through Ardf/Spdf - Ricoh MP C2504 Field Service Manual

7. Detailed Descriptions
1: When detecting A4/LT size -> Assume that it is A4 when SEF, LT when LEF.
2: When detecting A4/LT size -> Assume that it is LT when SEF, A4 when LEF.
3: Change to 8K/16K settings.
A3, B4 -> 8K LEF
A4 LEF, B4 LEF, A5 LEF -> 16K LEF
A4 SEF, B4 SEF, A5 SEF -> 16K SEF
• SP5-126 (Set F-size Document)
Selects the paper size for the F-size original.
0: When detecting Foolscap -> Assume that the size is 8 1/2"x13". (Default)
1: When detecting Folio -> Assume that the size is 8 1/4"x13".
2: When detecting F -> Assume that the size is 8"/13".
• SP4-308 (Scan Size Detection)
Sets CCD original size detection and APS original size detection.
0: Disable: Not detect original size
1: Enable: Detect original size by the CCD unit
2: APS: APS sensor is used for detecting original size.
• SP4-309-004 (Scan Size Detect:Setting LED PWM Duty)
If the user specifies that the pre-scan lamp is too bright, the brightness pre-scan can be
reduced by decreasing the value of SP4-309-004 (Scan Size Detect:Setting LED PWM Duty).
However, if the lamp brightness is reduced, size detection for a document with a large
number of solid images will be less accurate.
• SP5-135 (LG_Oficio Change)
1: When detecting LG size -> Assume that the size is 8 1/2"x14".
2: When detecting Oficio size -> Assume that the size is 8 1/2"x13.4". (Default)

Improved Tolerance to Black Lines When Paper Passes through ARDF/SPDF

The original document does not come in contact with the sheet-through exposure glass, which prevents
adhesive dirt (ball pen ink) on the document from adhering to the sheet-through exposure glass.
