Toner End Setting
Selects the detection type for toner end.
[0 to 2 / 0 / 1 step]
[0: 90 printouts, 1: No printout, 2: 10 printouts]
2213*
90 printouts: Toner end is determined if a low density image (Vref <
Vt(10)) is detected 90 times after toner near end.
If "1" is selected, the machine stops printing when the ID sensor
output drops below 0.9.
Select 1 or 2 if the customer normally makes printouts of very high
density.
Vref Setting
Adjusts the TD sensor reference voltage (Vref). Change this value after
replacing the development unit with another development unit that contains
toner.
[1 to 5 / 4 / 0.01 ]
2220*
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 VREF 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.
Reverse Interval
2221*
Adjusts the threshold for the reverse rotation of the drum and
development/transfer motors. This helps the drum and transfer belt cleaning
operations. This reverse rotation will interrupt a multiple printing job.
