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


When the PWSTOP signal is made to go high due to a failure, +5 V and +34 V are cut off (Figure 5.42).
