A paper passage test is carried out after the copier has completed warming
up.
<Procedure>
1. Select the paper source key. (Touch [Duplex] to check for paper passage
from the Duplex Unit.)
Note: If the paper source is not loaded with paper, an Add Paper mark
appears at that source.
2. Press the Start key to start the test cycle. The test runs until the paper
source runs out of paper.
3. If the Stop key is pressed, the copier feeds the current sheet of paper out
before halting. (Another press of the Start key will resume the test cycle.)
Set the output of each HV.
Note: This function is only for factory setting and should never be used in the
field.
Automatically adjusts the AIDC Sensor.
<Procedure>
Press the Start key to start the adjustment sequence.
Note: The copier automatically stops as soon as it completes the adjustment.
The Stop key may, however, be pressed to halt the sequence.
Automatically adjusts the ATDC Sensor.
<Procedure>
Press the Start key to start the adjustment sequence.
Note 1: The copier automatically stops as soon as it completes the adjust-
ment. The Stop key may, however, be pressed to halt the sequence.
Note 2: Since the adjustment is made based on the current toner-to-carrier
(T/C) ratio, run this function only when the starter has been replaced.
Running an F8 operation at any other timing results in incorrect
image density on the print.
Note 3: The ATDC Sensor control voltage automatically adjusted by this func-
tion is stored in memory as the current value for "ATDC Control" of
"Adjust." The data is also given for the "ATDC Set" value, an item of
the "Level History" display available from the Tech. Rep. mode.
