Surge protection circuit 2. Line filter block 3. Dial pulse generation circuit 4. On-hook circuit 5. Matching transformer 6. Hybrid circuit 7. Signal selection 8. Cl detection circuit 9. Power supply and bias circuit 3) Block description 1. Surge Protection circuit This circuit protects the circuit from the surge voltage occurring on the telephone line. · The AR1, AR2 protects the circuit from the 425V or higher line surge voltages. 5­8 UX-108H UX-178H 2. Line filter block The block is comprises of coil L2. 3. Dial pulse generation circuit The pulse dial generation circuit comprises of transistor Q1, the photocoupler PC2, PC8, and zener diode ZD9. Dial pulse supplied from CPU are amplified by transistor Q1 through a photo-coupler PC4 to the telephone line. 4. On-hook circuit This circuit comprises of CML relay and switch SW2, and CML and SW3 are for connection of the telephone line. 5. Matching transformer The matching transformer performs electrical insulation from the telephone line and impedance matching for transmitting the TEL/FAX signal. 6. Hybrid circuit The hybrid circuit performs 2-wire-to-4-wire conversion using the IC101 of operational amplifier, transmits the voice transmission signal to the line, and feeds back the voice signal to the voice reception circuit as the side tone.

List can be output. ROM is sum-checked, and RAM is matched. Result list is output. 10 sheets of check patterns are output every 5 minutes per sheet. Panel keys are tested. Result list is output. CHECK PATTERN MODE Check pattern is output. SIGNAL SEND MODE Various signals of FAX communication are output. MEMORY CLEAR MODE Back-up memory is cleared, and is set at delivery. SHADING MODE ALL BLACK MODE AUTO FEEDER MODE Shading compensation is performed in this mode. To check the print head, whole dots are printed over the interval of 2 m. Insertion and discharge of document are tested. 2­2 UX-108H UX-178H 3. Diagnostic items description 3. 1. Soft switch mode Used to change the soft switch settings. The soft switch which is stored internally is set by using the keys. The available soft switches are SW-A1 to SW-L2. The content of soft switches is shown in page 2-5 to 2-15. The contents are set to factory default settings. 3. 6. Signal send mode The mode is used to send various signals to the circuit during FAX communication. Every push of START key sends a signal in the following sequence. Moreover, the signal sound is also output to the speaker when the line monitor of the soft switch is on.
