BEND-Y Y-color laser distortion crrct:vert scan
Lv.1 Details To correct distortion of Y-color laser in vertical scanning direction.
(Digital registration)
As the value is incremented by 1, degree of distortion is changed by
1 micro m.
Y-color is the reference for M/C/Bk-color.
Use case When distortion occurs in vertical scanning direction
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
2) Output a test print in COPIER> TEST> PG> TYPE> 6 (Grid).
3) Perform visual check, and repeat the procedures as needed.
Caution In principle, do not change the setting because Y-color is the
reference.
Display/adj/set range -100 to 100
Unit 1 um
Default value 0
BEND-M M-color laser distortion crrct:vert scan
Lv.1 Details To correct distortion of M-color laser in vertical scanning direction.
(Digital registration)
As the value is incremented by 1, degree of distortion is changed by
1 micro m with reference to Y-color.
Use case When distortion occurs in vertical scanning direction
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
2) Output a test print in COPIER> TEST> PG> TYPE> 6 (Grid).
3) Perform visual check, and repeat the procedures as needed.

BEND-K Bk-clr laser distortion crrct:vert scan
Lv.1 Details To correct distortion of Bk-color laser in vertical scanning direction.
(Digital registration)
As the value is incremented by 1, degree of distortion is changed by
1 micro m with reference to Y-color.
Use case When distortion occurs in vertical scanning direction
Adj/set/operate method 1) Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
2) Output a test print in COPIER> TEST> PG> TYPE> 6 (Grid).

LSR-V-M1 Adj M wrt start pstn:vert scan, 1st sht
Lv.2 Details To adjust the write start position of M-color image in vertical scanning
direction when color displacement occurs only with the image on the
1st sheet.
As the value is changed by 1, M-color image moves by 1 pixel.
+: Move in the trailing edge direction
-: Move in the leading edge direction
Since image formation is performed based on Y-color, adjust the
position of M/C/Bk-color even if it seems that color displacement
occurs only with Y-color.
Use case When color displacement occurs only on the 1st sheet
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Caution Use this mode only when color displacement occurs on the 1st
sheet.
Display/adj/set range -5 to 5

LSR-V-C1 Adj C wrt start pstn:vert scan, 1st sht
Lv.2 Details To adjust the write start position of C-color image in vertical scanning
direction when color displacement occurs only with the image on the
1st sheet.
As the value is changed by 1, C-color image moves by 1 pixel.
+: Move in the trailing edge direction
-: Move in the leading edge direction
Since image formation is performed based on Y-color, adjust the
position of M/C/Bk-color even if it seems that color displacement
occurs only with Y-color.
