Sharp MX 3501N - Color Laser - Copier, Service Manual

Page: 51 / 448

MX3500N ADJUSTMENTS 6 – 6
1) Enter SIM8-1 mode.
2) Select an output mode to be adjusted with the mode key and
the scroll key.
3) Enter the adjustment value (specified value) of the middle
speed mode and press [OK] key.
Remark: By setting the default value, the specified voltage is
normally outputted.
The adjustment value of each color mode is specified on the label
attached to the MC/DV high voltage power PWB. Enter that value.
DVK:XXX DVC:XXX DVM:XXX DVY:XXX
When the adjustment value (specified value) of the middle speed
mode is set, the adjustment values of the other modes are auto-
matically set according to the middle speed mode setting in a cer-
tain relationship.
To adjust all the modes individually, first adjust the middle speed
mode, then adjust the other mode.
If the middle speed mode is adjusted after adjustment of all the
modes individually, the adjustment values of the other modes are
automatically changed. Use care for that.
Therefore, unless there may be an abnormality in the output volt-
age, there is no need to check the output value.
If it must be checked that the normal voltage is outputted or if an
adjustment is required by referring to the output voltage, follow the
procedures below.
