Initializing Error After the power is turned on, the SOC (IC300) initializes and checks each IC. The ROM (IC402) and SDRAM (IC400) are checked. If initialization fails for the ICs, the system will not boot up. In this case, please find the cause as follows. CROSS REFERENCE: NG Example (P.238) Power Supply Board Section (P.69) 157 KX-MB772CX-V1 12.3.14. Analog Section and Monitor Section This chapter provides the testing procedures required for the analog parts. A signal route to be tested is determined depending upon purposes. For example, the handset TX route begins at the handset microphone and the signal is output to the telephone line. The signal mainly flowing on this route is analog. You can trace the signal with an oscilloscope. The signal flow on each route is shown in the Check Sheet here. If you find a specific problem in the unit, for example if you cannot communicate with the H/S, trace that signal route locally with the following Check Sheet and locate the faulty point. 12.3.14.1. Check Sheet 158 KX-MB772CX-V1 12.3.14.2. DEFECTIVE ITS (Integrated Telephone System) Section 1. No handset and speakerphone transmission / reception Perform a signal test in the ITS or the NCU section and locate a defective point (where the signal disappears) on each route between the handset microphone and telephone line (sending), or between the telephone line and the handset speaker (receiving), or between the microphone and the telephone line (sending), or between the telephone line and the speaker (receiving). Check the components at that point. Check Sheet(P.158) is useful for this investigation. 2. No pulse dialing 3. No ring tone (or No bell) CROSS REFERENCE: Check Sheet (P.158) NCU Section (P.29) 4. No tone dialing CROSS REFERENCE: Check Sheet (P.158) 159 KX-MB772CX-V1 12.3.14.3. Detective TAM Interface Section 1. The FAX turns on, but does not arrive through TAM.

NO LCD INDICATION CROSS REFERENCE: Test Functions (P.89) 12.3.16. Sensor Section Refer to SENSORS AND SWITCHES for the circuit description. Perform an SENSOR CHECK to determine if the sensor is operating correctly. 1. Check the pickup sensor ... "FAILED PICKUP" 161 KX-MB772CX-V1 2. Check the paper exit sensor... "PAPER JAMMED" 3. Check the read position sensor ... "CHECK DOCUMENT" 4. Check the registration & manual paper sensor ... "PAPER JAMMED"

KX-MB772CX-V1 15 Maintenance 15.1. Maintenance Items and Component Locations 15.1.1. Outline MAINTENANCE AND REPAIRS ARE PERFORMED USING THE FOLLOWING STEPS. 1. Periodic maintenance Inspect the equipment periodically and if necessary, clean any contaminated parts. 2. Check for breakdowns Look for problems and consider how they arose. If the equipment can be still used, perform copying, self testing or communication testing. 3. Check equipment Perform copying, self testing and communication testing to determine if the problem originates from the transmitter, receiver or the telephone line. 4. Determine causes Determine the causes of the equipment problem by troubleshooting. 5. Equipment repairs Repair or replace the defective parts and take appropriate measures at this stage to ensure that the problem will not recur. 6. Confirm normal operation of the equipment After completing the repairs, conduct copying, self testing and communication testing to confirm that the equipment operates normally. 7. Record keeping Make a record of the measures taken to rectify the problem for future reference. 15.1.2. Maintenance Check Items/Component Locations 221 KX-MB772CX-V1 15.1.2.1.
