When the TD sensor control voltage (Vtcnt) is 4.3V, the TD sensor output
(Vt) is less than 0.7V.
Details:
When executing TD sensor initialization (SP3-030), the machine checks
the development unit for the presence of developer. If the error condition
is detected at this point, the machine determines that there is no
developer and issues the SC.
