Sub item Description
RSTR-DCN Restoration of the backup information of DC controller NVRAM retained in the controller's NVRAM to the DC controller NVRAM
Perform the following procedure after replacement of the DC controller PCB.
1) Using this item, restore the backup data of the DC controller retained in the NVRAM of the main controller PCB to the NVRAM of the DC
controller PCB.
2) Print the user data list by selecting "Initial setting/registration > Report output > List print > User data list".
3) Execute full correction by selecting "Initial setting/registration > Adjustment > Cleaning > Automatic gradation correction > Full correction".
CLR-DCN Clear of the backup information of DC controller NVRAM retained in the controller's NVRAM to the DC controller NVRAM
SEL-TALC Setting of TALC paper
ETB cleaning is performed 10 times at initial rotation.
INV-ATVC Setting to enable ATVC
Ignore ATVC and use a default value for the output value of each bias.
IMP-BNDG Setting for banding improvement
Perform idling with engagement of the developing assembly and disengagement of ETB.
AANY-0
/ AANY-1 Setting of any-any mode 0 / any-any mode 1
Combination of any-any mode 0 / any-any mode 1
AANY-0=0/AANY-1=0: Perform constant-speed cleaning after a job only when the paper size does not match.
AANY-0=1/AANY-1=0: Perform high-speed cleaning after all jobs.
AANY-0=0/AANY-1=1: Perform constant-speed cleaning after all jobs.
AANY-0=1/AANY-1=1: Perform high-speed cleaning after a job only when the paper size does not match.

Sub item Description
SPL27767 Setting of high-resistance paper
Decrease the final output value of transfer bias by 250V.
(Only when high-humidity OHT/high-humidity gloss film is not specified)
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL27267 Setting of 4mil OHT
Decrease the final output value of transfer bias by 500V.
(Only when high-humidity OHT/high-humidity gloss film/high-resistance paper is not specified)
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL23866 Setting of calcium carbonate paper
Apply the maximum attraction bias wherever possible regardless of the environment. Since there is no result of detection of attraction paper
resistance, set a transfer bias from the environment.
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL25407 Setting of thin paper/rough paper
Change the process speed to 4/5 speed. Use the temperature control table for thin paper/rough paper. (Thin paper only)
Do not change the process speed, but change the temperature control table. (Plain paper, Thick paper 2 only)
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL47267 Setting of high-humidity OHT
Decrease the final output value of transfer bias by 100V. (OHT only)
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL47667 Setting of prevention of re-transfer
Decrease the transfer bias for the 3rd/4th station depending on the environment.
(Only when high-humidity OHT/high-humidity gloss film/high-resistance paper/4mil OHT is not specified)
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL34691 Setting for improvement of color misregistration
Rotate the fixing motor in +0.5% speed up to the 10th page. Secure the wait time of 10 seconds when the 1st page is picked up at the time of initial
rotation, mode switching, or toner ejection.
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL14682 Setting for prevention of fogging 2
Turn off the pre-exposure operation. Do not add a transfer bias as measures to prevent a bird's foot print on the trailing edge.
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL25200 Setting for improvement of OHT transparency
Set the controlled temperature at 180 degC, and perform idling of the fixing machine for 45 seconds before initial rotation.
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL53649 Setting of engagement for monochrome mode
Perform full engagement of the ETB.
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL35607 Setting of measures for hot offset
Decrease the controlled temperature by 10 degC without exception.
Setting value: 0: OFF, 1: ON
[Factory setting value/Value after RAM clearing: 0]
SPL14660 Setting of the monochrome printer mode
Perform the monochrome print in ETB Bk engagement mode.
Setting value: 0: OFF, 1: ON
