Wake Activation Area (Photocell LED Output) The MS2421/MS2422/MS2431 scanner’s default power save mode† is Dual Action Power Save Mode #2 (see page 41). This power save mode turns the laser OFF after a configured period of non-use then turns the motor OFF after thirty-minute intervals. Any movement detected by the photocell in the activation area, shown below in grey, will cause the scanner to exit the power save mode.
Wake Activation Area Sensitivity (Photocell LED Output Range) Changing the Wake Area Sensitivity Level (Photocell LED Range Adjust) The MS2400 Series bar code scanner wake area sensitivity level can be set to the end users preference by scanning one of the Photocell Sensitivity adjustment bar codes below. *Max Photocell Sensitivity This feature enables the MS24xx to be at Max sensitivity or far sensing for the wake up photo transistor. ³ 2 2 1 2 0 0 * This is the default setting.
Audible Indicators When in operation, the MS2421/MS2422/MS2431 scanner provides audible feedback that indicates the status of the unit and the current scan. Eight settings are available for the tone of the beep (normal, six alternate tones and no tone) plus three volume settings. To change the tone or volume, refer to the Changing the Beeper Tone and Volume section of this manual. One Beep When the scanner first receives power, the blue LED will turn on and the scanner will beep once.
Visual Indicators Blue LED is located near the bottom corner of the vertical output window. When the scanner is ON, the flashing or constant illumination of the LED indicates the status of the scanner and the current scan. No Blue LED The blue LED will not be illuminated if the scanner is not receiving power from the host or transformer. They are also not illuminated when all lasers are turned off. Steady Blue When all lasers are active, the blue LED is illuminated.
Failure Modes Flashing Blue and One Razzberry Tone This indicates that the scanner has experienced a laser subsystem failure. The scanner will try up to three times to correct the failure condition. If the laser subsystem continues to fail, that subsystem (horizontal or vertical) will be shut down and an error indication will be shown on the Diagnostic Indicator Display. This error stays on the display until corrected.
Diagnostic Indicator Display There is a two-digit error code display located under horizontal output window near the top of the platter (see figure below). Figure 33. Error Code Display The following is a list of possible error codes and their meanings. Some errors will require immediate scanner maintenance. Error Code 01 38 Description Reserved 02 RAM ERROR – The scanner’s Random Access Memory (RAM) is tested as faulty. Return the unit for repair at an authorized service center.
Error Code Description 09 COPROCESSOR COMMUNICATION ERROR – The main microprocessor is not communicating with the interface coprocessor. The interface coprocessor may be in a fault condition with the host or just not able to respond. This error may appear when the scanner is configured for USB or RS485 interface applications or during an attempt to update the interface software through the flash utility. The unit should be repaired at an authorized service center.
Error Code Description 28 LASER #2 (RIGHT HORIZONTAL) UNDERCURRENT WARNING – The laser in the right horizontal scanning subsystem is drawing too little current. The laser is probably not on. This could be the result of a loss of the required set point in memory. Have the unit checked at an authorized service center. 29 LASER #3 (LEFT HORIZONTAL) UNDERCURRENT WARNING – The laser in the left vertical scanning subsystem is drawing too little current. The laser is probably not on.
Power Save Modes The MS2421/MS2422/MS2431 bar code scanners have five configurable power save modes. Refer to the MetroSelect Configuration Guide for additional information on Power Save Modes. 1. Blink Power Save Mode: Blinks the laser OFF & ON after a configured period of non-use. When the scanner recognizes a bar code it will exit the Blink mode. 2. Laser Off Power Save Mode: Turns the laser OFF after a configured period of non-use. The motor continues to spin allowing for a faster “wake” up time.
Beeper Options and Button Functions Changing the Beeper Tone Beeper tones may be configured incrementally using the following bar code. The new tone will be heard followed by a short pause. Two more new tones will be heard signifying the new setting has been stored in memory. The silent (no beep) tone is also selectable. N ³ 9 9 9 9 7 5 Changing the Beeper Volume Volume levels may be configured using the volume button or incrementally using the following bar code.
Startup When the scanner first receives power, the blue LED will turn on and the scanner will beep once. The scanner is now ready to scan. Power-Up Test Mode When a MS2421/MS2422/MS2431 scanner is first powered up, it cycles through a number of self-tests before starting normal operation. If there are any initial failures during this sequence of tests the scanner will beep or razz to indicate the error and an error code will appear in the diagnostic indicator display.

Maintenance Horizontal Scan Window Replacement Note: After the replacement platter has been installed, remove all protective film from the new platter’s window. The unit will not function properly if the protective film is not removed. Figure 38. Platter/Horizontal Scan Window Replacement * See replacement parts on page 3. ** For MS2431, use the same points as shown for the MS2421 to install the platter.
Daily Maintenance Smudges and dirt on the unit’s window can interfere with the unit’s performance. If the horizontal or vertical output windows require cleaning, use only a mild glass cleaner containing no ammonia. When cleaning the window, spray the cleaner onto a lint free, non-abrasive cleaning cloth then gently wipe the window clean. If the unit’s case requires cleaning, use a mild cleaning agent that does not contain strong oxidizing chemicals.
Troubleshooting The following guide is for reference purposes only. Contact a customer service representative to preserve the limited warranty terms. Symptom Possible Cause(s) Solution No LED, beep, or motor spin. No power is being supplied to the scanner. Check the transformer, outlet, and the power strip. Make sure the power cable is plugged into the scanner. During power up the unit beeps 3 times. A non-volatile RAM failure.
Symptom Possible Cause(s) Solution All Interfaces Scanner beeps at some bar codes and NOT for others of the same bar code symbology. The unit powers up but does not scan and/or beep. The unit beeps at some bar codes but NOT for others of the same bar code symbology. The print quality of the bar code is suspect. Check the character length lock. The aspect ratio of the bar code is out of tolerance. The unit is trying to scan a particular symbology that is not enabled.
Symptom RS232 Only The host is receiving data but the data does not look correct. Characters are being dropped. Possible Cause(s) Solution The scanner and host may not be configured for the same interface. Check that the scanner and the host are configured for the same interface. The intercharacter delay needs to be added to the transmitted output. Add some intercharacter delay to the transmitted output by using the MetroSelect Configuration Guide (PN 00-02407x).
