SPs 3801 and 3811 - Very
Important!!!!
!
Only initialize the TD sensor at these times:
"
At installation, exactly as explained in the procedure.
"
After you replace developer (only initialize the TD sensor for
the colour that you replaced)
"
As instructed in specific troubleshooting procedures.
!
Only initialize the sensor one time. Do not do it more than
one time.
!
Never do SP 3801 after doing SP 3811. If the TD sensor is
initialized twice for the same batch of developer, a fatal
error will occur with toner supply control.
!
If you do not obey the above instructions, you will get toner
scattering inside the machine.
"
It is possible that many instances in the field of toner
scattering are caused by initializing the TD sensor more than
one time.
!
To repair the machine, you must replace the developer
(after you clean the machine!).
#
If a technician initializes the sensor more than one time, the developer must be
replaced. But it is not easy to know that a mistake was made until toner
scattering occurs inside the machine. Then it is too late.
#
A common source of error is to replace one developer (for example, black), but
then do the TD sensor initialization for all colours. Then you have to replace the
C, M, and Y developers.
Why should we not initialize the TD sensor more than once?
