CONDITION
Phenomenon when set to DISABLE NOTE
44-1 DEVE ENABLE Toner concentration correction for developer
use frequency is not performed. Improper copy, toner dispersion, image high
density section abnormality, developer
dispersion, insufficient image density All functions
must be set to
ENABLE.
HUMID ENABLE Process section corrections for change in
humidity (toner concentration, transfer
voltage, resist roller rotation speed
correction) are not performed. Improper color balance, abnormality,
improper copy, toner dispersion, developer
dispersion, improper image density, image
shift, image flow, image dirt
DM POSI ENABLE OPC drum phase correction is not performed. Image color shift, banding
HT ENABLE Half-tone image density correction is not
performed. Improper half-tone image density, improper
copy, improper color balance, tone jump
TC ENABLE Transfer voltage correction for a change in
humidity or paper kind is not performed. Half-tone image section abnormality,
improper image density, low density inside
image outline
MD ENABLE Correction (laser power) for use frequency of
OPC drum (change in sensitivity) is not
performed. Insufficient image density
(The following adjustment items affect copy quality, but there is no need to adjust them frequently. In case of a trouble,
however, they should be checked and adjusted.)

(The following adjustment items do not affect copy quality directly.)
1) Adjustment items: ADJ M5, ADJ M11, ADJ M12, ADJ M14, ADJ M15, ADJ M16, ADJ M18, ADJ M19, ADJ M20, ADJ M23, ADJ M24, ADJ M25
(Relationship between servicing contents and copy quality adjustment)
Note that the procedures before and after the copy quality adjustment differ depending on the conditions of the machine and the servicing contents.
Follow the copy quality adjustment procedure flow to perform procedures according to the conditions.
There are following 5 major cases.
1) When installing
2) When performing the periodic maintenance
3) When replacing consumable parts in repair work
4) When not replacing consumable parts in repair/check work
5) When perform in repair/check work
