Epson stylus photo 1400 printer review
With ribbon from (logicboard :: powersupply) disconnected & USB Plugged in, the Win7 Device Manager does not trip.Not an Electrical Engineer, but for whatever reason, the power supply reads AC Voltages, 4VAC, 6VAC, 8VAC, etc… & reading AC voltages with only 1 prong of the meter, not 2 prongs on 2 different terminals.

The 9 position ribbon cable terminals then questionably read AC Voltages. When reconnecting ribbon cable from (logicboard :: powersupply), the beeping emits & the ribbon cable terminals stop DC Voltages on all 9 positions of the ribbon cable.The beeping sound emits again when reconnecting the ribbon cable from (logicboard :: powersupply).The beeping sound stops when disconnecting the ribbon cable from (logicboard :: powersupply) & reads DC voltages on all 9 positions of the ribbon cable.The beeping sound emits in this condition, disconnected entirely from every ribbon & plug on the printer.With the chassis removed & unplugged from every ribbon cable except the 9 position ribbon cable that connects the power supply to the logicboard.# I removed the logicboard chassis & diagnosed the Power Supply with a Multi-Meter. all chips & capacitors are fair visual condition.# next to teardown 1400 & attempt to diagnose the fuse, Waste Ink Tank & Power Supply. If the Logicboard will not power up the USB Port, then there is a Hardware failure / lockout.This indicates that the Logicboard is not sending any communications to the Windows7 USB Port.

I confirmed the 1400 USB Port is not tripping the Windows 7 Device Manager with any hardware changes.I downloaded various “WIC Reset Utilities” & with the 1400 USB port plugged in & powered up beeping, none of the WIC Reset utilites would recognize a printer on the USB Port.I concur reason the Water / Isopropyl I drilled in to some Ink Cartridges & left overnight could have somehow tripped the “Waste Ink Tank Counter”. # reviews indicate problem hypothesis “Waste Ink Tank Counter” or “WIC Reset”. I powered off & powered up again to a no power condition with the beeping noise.then after no response with the red ink light on / green power light.the yellow cartridge was off & slightly above the terminal block.the printhead cartridge terminal block was also loose as I broke off the tabs that lock it down.forgot to screw the printhead down to the tray with the 3 screws.Forgot the paper towel was under the printhead.The next day I powered up, red ink light on & green power button either continuous or flashing, uncertain.

Look for burnt or blackened areas as those would be your problem. take some pictures inside and post them so we can see close ups of the electrical boards.

Only do this if you feel comfortable doing it. Plug it back in then only tough it with voltage meter ends. Unplug printer, take covers off, be careful not to tough electronic boards as they can still retain power. If you take the cover off then you can get a voltage tester and see if the power coming from the outlet is getting through the power supply.BUT BE CAREFUL.electricity is very dangerous so do not touch anything with it plugged in. It sounds like it could be the power supply.
