Chapter 11: Troubleshooting
If you have problems with the display or the Midtronics
printer, try these troubleshooting suggestions:
The Display Does Not Turn On
• Check the connection to the vehicle battery.
• Press the POWER button.
• The vehicle’s battery may be too low to power the ana-
lyzer (below 1 volt). Fully charge the battery and retest.
• The analyzer’s 6 AA batteries may need to be replaced.
The STATUS LED Flashes
When a printer fault occurs, the STATUS LED flashes.
You can identify the fault by the number of sequential
ashes:
Printer STATUS LED
Sequence Condition Solution
* * * No paper Insert new paper
** ** ** Thermal head too hot Allow head to cool
*** *** *** Batteries weak Recharge printer
batteries for 16 hours
Data Will Not Print
• If the IR transmitter and receiver are not aligned, all the
data may not print. The infrared ports on the top of the
analyzer and on the printer below the MODE button
should be pointed directly at each other. The maximum
distance for reliable transmission between the ports is
17 in (45 cm).
To realign, press the END button to cancel the print job.
Verify alignment between the analyzer and printer; then
try to print the test results again.
• Make sure the printer is on. The printer shuts o after 2
minutes of inactivity to conserve the batteries. To turn
the printer on, briey press the MODE button. The
green STATUS light should turn on. Make sure you are
using the Midtronics printer. Other printers may not be
compatible.
• Direct sunlight interferes with infrared data transmission
and receiving. If the printer is not receiving data, remove
the printer and EXP from direct sunlight. If the printed
characters are not clear or are partially missing, recharge
the battery and reprint.
• If you are unable to print after ensuring the analyzer is
functioning, the printer is on, the batteries are good, and
the IR transmitter and receiver are aligned, check the
printer manual for further instructions or call Midtron-
ics at 800-776-1995 for assistance. (See “Patents, Limited
Warranty, Service” for more information.)
