Input Power and Connection Requirements
Datamax-O’Neil MF8i Installation Guide
If the end of your cable looks like these, then your existing installation may work.
Once connected, use a volt meter to ensure that the center pin on the DC jack is positive (+)
12 volts and with specifications for input voltage.
Cigarette Lighter Adapter
(part # 510002-102)
You can connect the cigarette lighter adapter to any universal 12 volt cigarette lighter plug.
If you want the printer to operate when the vehicle is turned off, make sure the cigarette
lighter adapter is powered when the vehicle power is off. If the printer does not operate from
the cigarette lighter adapter, check the fuse. You can replace the fuse with a Bussman 250
volt 7 amp fuse.
Battery
(part # 550036-000)
Truck power can be noisy, inconsistent, have voltage dips and interruptions, and is
considered “dirty power”. If all power requirements are met but your printer is acting
inconsistently, your vehicle may not be able to run the printer using your vehicle's power
source. In this instance, Datamax-O’Neil HIGHLY recommends operating your printer using
the printer's battery (while connected to vehicle power). Using the printer's battery reduces
ripples and interruptions, and is a cleaner power source. The battery is also a lower cost
solution than converters.
Note: DO NOT connect to the printer if the center is not positive 12 volts. You will damage
the printer.
