2471 [Thin:LE Correct] DFU
Thin: Leading Edge Correction
Adjusts the correction of the thin paper to the paper transfer roller current or discharge
plate DC at the paper leading edge in each mode. SP2453 and SP2457 are
multiplied by these SP values.
Std: 260 mm/sec, Low: 85 mm/sec
2-471-001 PTr:Std:1
2-471-003 PTr: Low: 1st
2-471-005 SepaDC:Std:1st
2-471-007 SepaDC:Low:1st
2472 [Thin:SW Tmng:LE] DFU
Thin: Switch Timing: Leading Edge
Adjusts the bias/ voltage switch timing of the paper transfer roller/ discharge plate at
the paper leading edge between the erase margin area and the image area.

2473 [Thin:TE Correct] DFU
Thin: Trailing Edge Correction
Adjusts the correction coefficient to the paper transfer roller current or discharge plate
DC at the paper trailing edge in each mode. SP2453 and SP2457 are multiplied by
these SP values.
