INTROT-1 Set ATR ctrl patch density dtct interval
Lv.1 Details To set execution interval of patch density detection executed at ATR
control.
By changing the setting value, execution intervals at last rotation and
at paper interval are changed.
Decrease the value if E020 error occurs frequently. As the execution
frequency is increased, correction accuracy for density variation is
increased. Since patch density detection is linked with low duty toner
ejection, lowering of density can be prevented by increasing the
frequency.
When the value is increased, downtime can be reduced because of
decrease of execution frequency, but an image failure might occur.
Use case - When E020 error occurs frequently
- Upon user's request (decrease downtime)
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and
press OK key.
Display/adj/set range -1 to 3
-1: Every 30 sheets at last rotation, every 80 sheets at paper interval
0: Every 50 sheets at last rotation, every 100 sheets at paper interval
1: Every 100 sheets at last rotation, every 150 sheets at paper
interval
2: Every 150 sheets at last rotation, every 200 sheets at paper
interval
3: Every 200 sheets at last rotation, every 250 sheets at paper
interval
Default value 0
INTROT-2 Set of auto adjustment execute interval
Lv.1 Details To set the paper interval to execute auto adjustment (D-max control,
D-half control).
As the value is incremented by 1, the paper interval is increased by 1
sheet.
If a new Drum Unit whose number of fed sheets is 1000 or less is
installed, the interval is 250 sheets at a maximum.
Use case When matching the use environment of the user.
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Caution Increasing the number of sheets (widening the interval) causes
higher frequency of image failure.
Display/adj/set range -20 to 2000
Default value 0

DMAX-SW Setting of D-max control timing
Lv.2 Details To set the D-max control execution timing.
When the density variation is not within the requested range at
continuous output of a large volume of papers (long job length), set 2.
When keeping the productivity even though there are some density
variations, set 1.
Use case - When the density variation is not within the requested range at
continuous output of a large volume of papers
- When keeping the productivity even though there are some density
variations
Adj/set/operate method Enter the setting value, and then press OK key.
Display/adj/set range 0 to 2
0: Not used, 1: At last rotation, 2: At paper interval with 1/1 speed
and last rotation
Default value 2
BK-4CSW Set simple full clr mode: hvy ppr, Bk-m
Lv.2 Details To set the conditions to switch single Bk-color mode to simple full
color mode according to the type of heavy paper.
In single Bk-color mode, shock image at 75/122 mm from the leading
edge is likely to occur due to impact triggered by paper entering the
secondary transfer section.
By switching to simple full color mode where black is made by using
small amount of Y, M and C toners, shock image is alleviated.
When 0 (normal) is set, the mode is switched to simple full color
mode with heavy paper 3 after printing the specified number of
sheets since the replacement of the Drum Unit (Bk).
When 1, 2, or 3 is set, simple full color mode is always applied to
heavy paper 1/2/3.
When 4 is set, it is not switched to simple full color mode.
Use case When shock image occurs with heavy paper at single Bk-color mode
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 4
0: Normal, 1: Heavy paper 3, 2: Heavy paper 2/3, 3: Heavy paper
1/2/3, 4: OFF
Default value 0
SVMD-ENT Setting of entry method to service mode
Lv.2 Details To set the way to get in service mode to prevent information leak.
Use case As needed
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/adj/set range 0 to 1
0: Factory default
