Setting the main high voltage
Description
Changes the surface potential by changing the grid control voltage. Also performs main charging. Also
changes the setting of main charging copy quantity correction.
Purpose
To set the surface potential or check main charging. Also used when reentering data after initializing the set
data.
Start
1. Press the start key.
2. Select the item using the exposure adjustment keys.
Method for main charger output
1. Press the start key. The selected operation starts.
2. To stop operation, press the stop/clear key.
Setting the grid control voltage
1. Change the setting using the zoom +/- keys.
Increasing the setting makes the surface potential higher, and decreasing it makes the potential lower.
2. Press the start key. The value is set.
Setting the main charging copy quantity correction
1. Change the setting using the zoom +/- keys.
Copy interval: Sets the time interval from the previous copying. If the time from the previous copying
exceeds this preset value, the copy quantity counter will be reset.
Copy quantity: Sets the copy quantity from which copy quantity correction starts. When the copy quan-
tity counter reaches this preset value, correction will start.
Correction amount: Sets the correction amount for copy quantity correction.
Set the values in the range from 5 to 120 minutes for copy interval, from 10 to 2,000 sheets for copy
quantity, and from 5 to 50 bits for correction amount.
2. Press the start key. The value is set.
Supplement
While this maintenance item is being executed, copying from an original is available in interrupt copying mode
(which is activated by pressing the interrupt key).
Completion
Press the stop/clear key when main charger output stops while a selection item is displayed. The screen for
selecting a maintenance item No. is displayed.
Maintenance
item No.
