Page 28: Initialization
Page: 16 Service Guide PM3410 Chapter 2 Principles of Operation 2.1.03 Initialization The printer is initialized whenever it is powered ON or when the I-PRIME signal is received from the host at the parallel interface. The initialization process is performed as listed below. 1.
Page 30: Interface Control
Page: 17 Service Guide PM3410 Chapter 2 Principles of Operation 2.1.04 Interface Control The printer is capable of serial or parallel operation. The desired interface method is selected by sliding the interface cover to expose the desired connector. When this is done, the interface select switch is turned ON or OFF to inform the Interface/Motor Control LSI (Q5: B562 13497) of the selected interface.
Page 31 The interface signals (DTR, RTS, SSD and TD) output from Q5 are converted from TTL levels to RS232-C levels by the line driver (Q12) and sent to the serial interface connector.
