1. INTRODUCTION Troubleshooting is a collection of solution procedures that service personnel should follow if an error or malfunction occurs in the machine. It is difficult to determine troubleshooting procedures for all possible problems that may occur in the future. Therefore, this chapter describes typical problem cases and recovery procedures for these.
Checks before Commencing Troubleshooting Check the following items before commencing repairs on the machine. Operating environment (1) The machine is placed on a flat, stable surface. (2) The machine is used in a clean environment where the temperature is between 5°C (41°F) and 35°C (95°F) and the relative humidity is maintained between 20% and 80%.

CHAPTER 4 ADJUSTING AND UPDATING SETTINGS AS REQUIRED AFTER PARTS REPLACEMENT This chapter describes adjustments and updating of settings, which are required if the main PCB ASSY and some other parts have been replaced. CONTENTS 1. IF YOU REPLACE THE MAIN PCB ASSY..............4-1 1.1 Installing Firmware ....................
1. IF YOU REPLACE THE MAIN PCB ASSY <What to do after replacement> • Installing firmware (Panel Main Firm / Main Firm) • Setting by country • Initializing the EEPROM of the main PCB ASSY • Setting serial number • Acquiring white level data •...
Installing Firmware 1.1.1 Checking firmware version Check whether the firmware installed on the main PCB is the latest version. If it is the latest version, there is no need to install the firmware. If it is not, be sure to install the firmware to the main PCB as described in "1.1.2 Installing firmware"...
(12) Open the temporary folder and double-click "Filedg32.exe" to start it, then select the "Brother Maintenance USB Printer". (13) Drag and drop the main firmware (LZXXXX_$.upd) in the same folder onto the "Brother Maintenance USB Printer" icon. The firmware file is loaded to the machine, and installing to the flash ROM starts.
(3) In the [Product Category] field, select the [4 Other-Model]. (4) Select [ADS 2012 MODEL] in the left bottom field of the BrUsbSn. (5) In the [Port] field, select the port number assigned to the Brother Maintenance USB Printer. If the port number is unknown, follow the steps below to check it.
Acquiring White Level Data <ADS-2500W/2600W> (1) Press the [5] key twice in the initial state of maintenance mode. (2) Press the [Start] key. "SCANNER AREA SET" is displayed on the LCD, and white level data is acquired. The machine returns to the initial state of maintenance mode. <ADS-2500WE/2600WE>...
Page 117
Setting Double Feeding Sensor Threshold (1) Connect the machine to your computer using the USB cable in the initial state of maintenance mode. (2) Double-click "BrADSmt1.exe" that was saved into the computer to start it. (3) Select the model name in the [Select model:] box, and click the [Start] button. The double feeding sensor threshold is reset.
Checking Operation after Repair Perform the steps below to check the machine's condition after repair or adjustment. (1) Prepare two DS-001 (LD1625001) test charts and set them to the document tray so that both sides of the test chart can be scanned. (2) Press and hold the key for approximately five seconds while the machine is in the ready state.
Page 119
(10) After the scanning, compare the scanned data on the test chart which framed red in the figure below with the ones in the limit sample. If the result is worse than the limit sample, perform procedures in "Acquire white level data and set CIS scan area" again. And then wipe the first and second side CIS glass with a dry cleaning cloth four times in the same direction, and follow the instructions above again to scan.

(10) After the scanning, compare the scanned data on the test chart which framed red in the figure below with the ones in the limit sample. If the result is worse than the limit sample, perform procedures in "Acquire white level data and set CIS scan area" again. And then wipe the first and second side CIS glass with a dry cleaning cloth four times in the same direction, and follow the instructions above again to scan.

CHAPTER 5 SERVICE FUNCTIONS This chapter describes the maintenance mode which is exclusively designed for the purpose of checking the settings and adjustments using the buttons on the control panel. This chapter also covers not-disclosed-to-users function menus, which activate settings and functions or reset the parts life.
1. MAINTENANCE MODE Maintenance mode is exclusively designed for checking, setting, and adjusting the machine using the buttons on the control panel. These buttons allow you to execute sensor operation check, test printing, log information and error code display, or worker switch (WSW) setting. How to Enter Maintenance Mode 1.1.1 Method of entering end-user accessible maintenance mode The maintenance mode functions should only be accessed by service personnel.
1.1.2 Method of entering maintenance mode for service personnel <Operating Procedure> (1) While the machine is in the ready state, press and hold the button. The following display appears on the LCD. (2) Press and hold the 4th box with no display. The following display appears on the LCD. (3) Press the [*], [2], [8], [6], and [4] keys on the LCD in this order.
List of Maintenance Mode Functions Function code Function Refer to: Initialize EEPROM parameters ADF performance test Set worker switches (WSW) Check LCD operation Check control panel button operation Save NetConfig data Display software version Check sensor operation 5-10 Change USB No. return value / Adjust left-end print start 5-11 position on second side when duplex printing Fine-tune scanning position...
Details of Maintenance Mode Functions 1.3.1 Initialize EEPROM parameters (function code: 01, 91) <Function> This function is used to initialize the setting values for operation parameters, user switches, and worker switches (WSW) registered in the EEPROM. Entering function code 01 initializes most EEPROM areas.
