Troubleshooting the printer
If AE5809 is not connected to a 9V battery or the paper sensor does not detect any paper in the compartment during printing, the analyzer
displays one of the error messages listed in the table:
Error message
INSERT PRINTER PAPER
VOLTAGE TOO LOW TO PRINT
Troubleshooting via test
If the display does not switch on:
1. Check its connection to the battery.
2. The battery voltage may be too low ( < 1.0V) to power the analyzer. Fully charge the battery and retest.
3. The 9V battery in the analyzer may need to be replaced. Refer to Replacing battery in AE5809.
Surface charge detected: There will be surface charge on the battery if the engine has run or the battery has been charged. The analyzer
will prompt you to eliminate the surface charge and then start the test.
1. Follow the instructions shown on the display.
2. When the surface charger has been eliminated, the analyzer will retest.
System noise/instable battery: The analyzer has detected the noise resulted from the computer or ignition and has tried to retest. Ensure
that all vehicle loads have been switched off and ignition key has been turned to the OFF position. The analyzer will automatically retest
when it detects no system noise.
・You may be too close to the noise source, such as a charger or other high-current equipment. In this case, stay away from the noise
source and retest.
・If no noise source is found, fully charge the battery and retest. If this message is still displayed after recharging, replace the battery.
・Disconnect the battery cables and retest.
・The battery is very weak or it has just been charged, thus its electrical activity is so high that it affects the test results. Voltage of a fully
charged battery shall steady quickly. After that the analyzer will automatically retest. For a weak battery, charge the battery and retest.
Non-12V battery detected: You are trying to test a non-12V battery out of the vehicle or the batteries are connected in series.
24 V system detected: You are trying to test two batteries in a 24V system in the vehicle. Disconnect the batteries from each other and test
them one by one.

Measures
Make sure the printer is installed correctly.
Replace to a new paper roll.
Make sure the sensor is clean and intact.
The analyzer can print only when it is connected to a battery with voltage not lower than 9V.
Connect the printer to a battery with voltage high enough.
Make sure the analyzer is correctly connected to the negative (-) and positive (+) terminals.
Make sure both sides of the clamps are securely connected
