Which I assume means that the unit isn't taking a charge. All four of our scanners are doing this which makes me think it might be a driver thing. Any thoughts on this?

Horisontal line: I assume you mean a line across the paper movement direction. Please, inspect if the line is repeating on exact distance from one to the other. Measure the distance, divide by Pi (3.14) and you'll get the diameter of the faulty roller. Also, please, make a half print test page (open the cover in the middle of the printing process). Inspect if the line is appearing before the fusing unit or after it.
Try printing with different cartridge, just to be sure the cartrige is causing the problem.
Primary charge roller and its bearrings can be dirty and not charging enough the drum, causing black lines
Weared stripe on the OPC drum caused by friction with jammed paper improperly pulled out can also be the root of the problem. Faulty laser-scanner unit can also write black lines randomly. Weared teflon sleeve on the fusing unit can accumulate toner and print repetitive defects.
If all 4 rings are red that means that something isn't plugged in correctly. Try unplugging everything, then plugging them back in if you can't find what isn't plugged in.
Remove covers taking care of the speaker wire. Remove screw for the green wire on disp. board and then the two screws holding the display board in place. Carefully remove the metal shield can with the four locking tabs. there are four grain of wheat lamps, two on each side of the display 12v/60mA DC. lamp # 7219 and radio shack sell them They are located in the white rubber holders on each side of the dissplay. unsolder the wires, pull up rubber white holder, remove bulbs, remove rubber light covers and put these on new lamps, slide lamp wires into rubber holders and then holders back to display pcb.

Hi I solved the problem by taking off the battery for around 1 hour.
I attached the battery again.
And press hold switch around 10 seconds.
The unit booted and it proceeded to auto configure and auto installed program soft wares.
I realized that the unit is self shutting off.
Solution is go to setting.go to system.go to back light menu. on backlight on external power .Be sure to uncheck turn off backlight if devise is not used for 1 minute.
Be sure to check turn on the back light when button is pressed or the screen is tapped.
press ok to activate the setting.
For maximized battery power and optimized power usage .go also to back light and go to brightness level. Slide the battery and power to almost the 2ndlevel .
Hope this also will be applicable to other o2 xda iis configuration.
1) Plug your power adaptor to main unit 2) locate "power on" switch and change it to "off"
after doing this steps you will see a red light which means the unit is charging.
note: for some portable player once the charging is complete this red light changes color either orange or green which means the battery already full charge. but it is adviceable to charge battery for atleast 2hrs.
Four flashes indicates a problem with the backlight on the TV. It can be caused by the backlight inverter board (the power supply for the backlight) or by defective backlights in the panel It is USUALLY the backlight inverter board that is bad, but I have seen both components fail at various times. This set is fairly new and should still be withing the one year warranty, so you should contact Sony at 800-222-SONY to get it repaired. Be sure to rate this solution. Thanks!
had same exact problem. my unit would come on for a minute and then go black. if you take the silver ring around the face you will see the four screws to take the unit apart if you do have to replace the battery. however first try hitting the reset button on the right side of the unit. remember the cover needs to be off. i hit the reset and my unit powered on with no problems
