Copies After Toner Near-End 2213*
Selects the number of copies that can be printed once the copier has detected
toner near-end.
[0~2/0/1 step]
[0: 90 copies, 1: No copies, 2: 10 copies]
Notes:
• If "1" is selected the machine stops printing when the TD sensor output drops
below the prescribed level.
• Select 1 or 2 if the customer normally makes copies of very high density.
Vref Manual Setting 2220*
Adjusts the TD sensor reference voltage (Vref). Change this value after replacing
the development unit with another development unit that contains toner.
[1.0 ~ 5.00 V / 4.00V / 2.0 step]
1. Check the value of SP2-220 in both the machine containing the test unit and
the machine that you are going to move it to.
2. Install the test development unit, and then input the V
REF for this unit into SP2-
220.
3. After the test, put back the old development unit, and change SP2-220 back to
the original value.
Notes:
