PROCESS CONTROL
August 2006
6-88
2. Page interval process control (Vsp detection between pages)
This function operates only when SP3042 001 (Vtref correction) is set to "ON"
(default). The Vsp ID sensor pattern is created between the page images on the
ITB (Default: Every 10 pages). This interval can be adjusted with SP3171.
[A]: ID Sensor – K
[B]: ID Sensor – Y, C, M
See Section 6.12.9 for the actual locations of the ID sensors.
The toner M/A (Mass per Area) is calculated from this sensor pattern after every
10th page:
Target M/A
K Toner
Uses the setting of SP3161 001.
Y, M, C Toner
Uses the settings of SP3531 002 to 004
Toner supply is based on Vt - Vtref
•
If the pattern is too dark (too much toner):
Æ
Vtref is increased
Æ
Toner supply amount decreases
•
If the pattern is too light (not enough toner):
Æ
Vtref is reduced
Æ
Toner supply amount increases
Also, the TD sensor detection is done for every page:
•
If Vt < Vtref, the toner supply amount is lowered.
•
If Vt > Vtref, the toner supply amount is raised.
