Chapter 2. Operation
Print Station Operation
Stim Adjustment
Stim and stim gram adjustment should be done only by a trained service
technician. It is never required as part of normal operation.
Stim Phase Adjustment
The phase setting may require adjustment when the print station reaches
a maximum operating temperature, or if the operating environment
changes significantly. There are 16 phase settings to choose from. Use
the following procedure to find and record the stim phase window:
1. From the Control screen, select Service Menu (8)
2. Select Parameters Menu (9), and enter the password.
3. Select Stim Phase (4).
4. Select each of the 16 different phase settings. Record all phase
settings that print test patterns of good quality.
5. Examine the printed test patterns. Several adjacent settings should
provide good print quality. These phase settings are the phase
window.
6. Find the center of the Phase window, then set the phase one value
above the center. This is the set point.
Charge Voltage Adjustment
Use the following procedure to find and record the charge voltage
window:
1. From the Control Menu screen, select Service Menu (8).
2. Select Parameters Menu (9),and enter the password.
3. Select Charge Voltage (5).
4. Lower the charge voltage to find the lowest charge voltage that will
allow printing without dark defect.
Lowest charge voltage setting: ________ VDC.
5. Raise the charge voltage to find the highest charge voltage that will
allow printing without pickout.
Highest charge voltage setting: ________VDC.
6. Calculate the set point of the charge voltage range.
a. Subtract the lower charge voltage from the upper charge voltage.
This value is the Charge Voltage window.
b. Divide theCharge Voltage window value by 2 and add the result
to the lower charge voltage.
7. Set the center point of the range to this result.
8. Press ESC, then select Service Menu (9) and Control Menu (8) to
return to the Control Menu screen.
