AUTO-DH 1 ON/OFF D-max/multi tone ctrl: wrmup rtn
Detail To set whether to execute D-max control and real-time multiple tone control (full) at warm-up
rotation.
When 0 is set, the control is not executed.
When 1 is set, it is executed only in an HH (high temperature and high humidity) environment.
When 2 is set, it is executed in all environments.
Use Case When image smear occurs in an HH environment
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 2
0: OFF, 1: ON (HH environment only), 2: ON (all environments)
Default Value 0
PCHINT-1 2 Setting of ATR patch formation interval
Detail To set the number of sheets as the intervals to execute patch detection by ATR control.
Decrease the value when hue variation occurs, and increase the value to increase the productivity.
Use Case
- When hue variation occurs
- Upon user's request (to reduce downtime)
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 5
0: At paper interval for every 50 sheets, at last rotation for every 35 sheets
1: At paper interval for every 100 sheets, at last rotation for every 70 sheets
2: At paper interval for every 200 sheets, at last rotation for every 140 sheets
3: At paper interval for every 400 sheets, at last rotation for every 280 sheets
4: At paper interval for every 700 sheets, at last rotation for every 490 sheets

PCHINT-V 2 Adj ATR patch VD counter total VL intvl
Detail To adjust the interval of the total video counter value, that is the condition to execute patch detection
by ATR control.
Decrease the value when hue variation occurs, and increase the value to increase the productivity.
Use Case - When hue variation occurs
- Upon user's request (to reduce downtime)
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 5
Default Value 2
DELV-THY 2 Set image ratio for Y-color toner eject
Detail To set the threshold value of average image ratio of Y-color, that is the condition to perform the
low duty toner ejection sequence.
When fogging occurs while making a large number of outputs of low duty images, increase the
value. Execution frequency of the toner ejection is increased so fogging is alleviated, but toner
consumption is increased.
If the user does not want too many waste toner when low duty image is output, decrease the value.
Toner consumption is decreased, but fogging is likely to occur.
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 5
0: 0%, 1: 1%, 2: 2%, 3: 3%, 4: 4%, 5: 5%
