SCANNER OPERATION WAKE ACTIVATION AREA (PHOTOCELL LED OUTPUT) The MS2421/MS2422 scanner’s default power save mode† is Dual Action Power Save Mode #2 (see page 34). 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.
SCANNER OPERATION 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. * Maximum Photocell Sensitivity This feature enables the MS24xx to be at Max sensitivity or far sensing for the wake up photo transistor. * This is the default setting.
SCANNER OPERATION INDICATOR DESCRIPTIONS Audible When in operation, the MS2421/MS2422 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, 6 alternate tones and no tone) plus three volume settings. To change the tone or volume, refer to the Changing the Beeper Tone & 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.
SCANNER OPERATION INDICATOR DESCRIPTIONS Visual Steady Blue When all lasers are active, the blue LED is illuminated. The blue LED will remain illuminated until all lasers are deactivated. Steady Blue and Single blue Flash When the scanner successfully reads a bar code, the blue LED will flash and the scanner will beep once. If the blue LED does not flash or the scanner does not beep once, then the bar code has not been successfully read.
SCANNER OPERATION INDICATOR DESCRIPTIONS Diagnostic Indicator Display There is a two-digit error code display located under horizontal output window near the Metrologic logo on the platter (see figure below). Figure 31. Error Code Display (Optional Product Roll Bar Shown) The following is a list of possible error codes and their meanings. Some errors will require immediate scanner maintenance.
SCANNER OPERATION INDICATOR DESCRIPTIONS Diagnostic Indicator Display ERROR CODE DESCRIPTION 11 SWITCH ERROR – The switch used for volume selection or sleep mode is detected in error (always closed). The condition is self-correcting if possible. If the error persists, return the unit for repair at an authorized service center. The scanning operation can continue with this error active. 21 LASER #1 (VERTICAL) ERROR – The laser in the vertical scanning subsystem denotes a failure.
SCANNER OPERATION INDICATOR DESCRIPTIONS Diagnostic Indicator Display ERROR CODE DESCRIPTION 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. This could be the result of a loss of the required set point in memory. Have the unit checked at an authorized service center. 31 MOTOR #1 (VERTICAL) ERROR – The motor in the vertical scanning subsystem denotes a failure.
SCANNER OPERATION POWER SAVE MODES The MS2421/MS2422 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.
SCANNER OPERATION 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. Next Beep Tone 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.
SCANNER OPERATION 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 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 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 36. Platter/Horizontal Scan Window Replacement * See replacement parts on page 3. † If the platter on the MS2421 is not equipped with a product weight roll bar / lift handle, it can be removed using the same method as shown for the MS2422.
MAINTENANCE DAILY MAINTENANCE Smudges and dirt can interfere with the proper scanning of a bar code. Therefore, the horizontal and vertical output windows will need occasional cleaning. For the vertical and horizontal (platter) glass windows: 1. Spray glass cleaner onto lint free, non-abrasive cleaning cloth. 2. Gently wipe the scanner windows until clean.
TROUBLESHOOTING The following guide is for reference purposes only. Contact a Metrologic representative at 1-800-ID-METRO or 1-800-4363876 to preserve the limited warranty terms. Symptom Possible Cause(s) Solution All Interfaces 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.
TROUBLESHOOTING Symptom Possible Cause(s) Solution All Interfaces The print quality of the bar code is suspect. Scanner beeps at some bar codes and NOT form others of the same bar code symbology. Check the character length lock. The type of printer and/or the printer settings could be the problem. Check the print mode or change the printer settings. For example change to econo mode or high speed. The aspect ratio of the bar code is out of tolerance.
TROUBLESHOOTING Symptom Possible Cause(s) Solution RS232 Only The host is receiving data but the data does not look correct. 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. Characters are being dropped. 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 (MLPN 0002407x).
