7. Toner
is being deposited in the non-image
area of the photoreceptor drum.
a. Developer bias voltage is not correct.
b. Toner concentration is too high
(2510, 2515 WIO Tag 2, 7, or 89): Enter
the diagnostic mode. Enter the code [L],
press Start, enter the code [g], press Start,
enter the code [J], press Start. Wait t w o
minutes then enter the code [A], press
Start, enter the code [C], press Start.
Measure the developer
bias
voltage where
the wire connects t o the magnetic roll.
The voltage is 200 2 2 0 VDC, if not go t o
CQ 25 Developer Bias RAP.
(2515 W I Tag 2, 7, or 89): Enter the
diagnostic mode. Enter the code [L], press
Start. Enter the code [A], press Start, enter
the code [C], press Start. Measure the
developer bias voltage where the wire
connects t o the magnetic roll. The voltage
i s 200 2 2 0 VDC, if not go to CQ 25
Developer Bias RAP.
(2515 W l Tag 2, 7 or 89) :
Enter the
diagnostic mode. Enter the code [L], press
Start. Enter the code [A], press Start. Wait
until the motor starts (approximately 30
seconds), then enter the code [y], press
Start.
(2515 WI Tag 2 or 89) If [y] is greater than
6, go t o J High Toner RAP, Section 2.
(2515 WI Tag 7 )
If [y] is greater than
8, go
t o J High Toner RAP, Section 2
