(5) External signal
The power supply receives the PWSTOP signal (Power Stop signal, connector pin No. 2) from other printer
components that enables the printer controller to turn off +5 V and +34 V outputs even if problem that can result
in power failure occurs outside the power supply.
When power is turned on, the PWSTOP signal is kept low and +5 V and +34 V output go to the prescribed
values.
When the PWSTOP signal is made to go high due to a failure, +5 V and +34 V are cut off (Figure 5.42).
