poor cleaning.)
Note 1:
If the output from the main charger or the developer bias is abnormal, replace the high-voltage transformer with a new one and
output the chart again. If the output stays abnormal, check if the harness connecting the LGC board and high-voltage
transformer is open-circuited, if the power supply is normal and if the main charger wire is dirty.
Note 2:
Toner density correcting method
Change the setting value ‘Toner density life correction setting (08-414)’ (6 is the default setting.)
3: Appox. 1.5% lower than the current value
7: Appox. 0.3% higher than the current value
4: Appox. 0.8% lower than the current value
0: Appox. 0.5% higher than the current value
5: Appox. 0.3% lower than the current value
1: Appox. 0.8% higher than the current value
6: The current value (Default setting)
2: Appox. 1.5% higher than the current value
<Caution for correction>
When increasing or decreasing the toner density too much, the image may become poor or the life of developer material,
cleaner, photoconductive drum and fuser unit, etc. may shorten. Therefore it is not recommended to correct (to shift) the toner
density basically. If it is shifted, make sure that the image may be improper in a few minutes after shifting.
