Psion Teklogix MLP 3040 Series User Manual

To verify that the printer’s internal battery charger is functioning properly, perform the following steps. 

•  Test the power adapter (100-240VAC/50-60Hz, 12/24VDC adapter) with a voltmeter to verify that its 

output voltage is 9 VDC. 

•  Connect the power supply to a power source and then connect it to the printer. 
•  Verify that the printer’s   Battery Indicator is illuminated.  If illuminated, the charging circuit is 

functioning properly.   

Note:   that if the battery is already fully charged, the   Battery Indicator will turn off after a short 

time. 

•  After the battery has been charged for five minutes, disconnect the power supply. 
•  Perform a printer Self-Test. 

o

 

Make sure the printer is turned off.  The power indicator will be off and the LCD Display will 
be blank. 

o

 

Press and hold the   Paper Feed Button. 

o

 

Continue holding the   Paper Feed Button and turn the printer on using the   Power Button 
until “Printing Current Menu Values” is displayed. 

•  If the printer successfully prints the Self-Test, the battery is functional.  If the Self-Test does not 

complete and the printer turns itself off, repeat this test with a known good battery. 

•  Once this test has completed successfully, allow the battery to fully charge.  At the end of this time the 

 Battery Indicator will turn off.   

Note:  If the printer is turned on, the battery status shown in the bottom right corner of the LCD 

display will always show a “full” battery whenever the printer is connected to the power 
supply. 

If the printer and battery do not appear to successfully pass these tests, refer to the Troubleshooting section for 
possible causes and solutions. 

Note:  This test only verifies that the power adapter, the internal charging circuit, and the battery are 

functioning properly.  This test does not provide a valid indication of the relative capacity of the battery 
or how long it may hold a charge.
