# After flushing the printhead with water / isopropyl
 
# also leaving ink cartridges with water / isopropyl in the printhead overnight, also with a paper towel under the printhead & above the cleaning station to absorb any water / isopropyl.
# The next day I powered up, red ink light on & green power button either continuous or flashing, uncertain
# Forgot the paper towel was under the printhead
# forgot to screw the printhead down to the tray with the 3 screws
# the printhead cartridge terminal block was also loose as I broke off the tabs that lock it down
# the yellow cartridge was off & slightly above the terminal block
# then after no response with the red ink light on / green power light
# I powered off & powered up again to a no power condition with the beeping noise.
Tech:
 
# reviews indicate problem hypothesis “Waste Ink Tank Counter” or “WIC Reset”. I concur reason the Water / Isopropyl I drilled in to some Ink Cartridges & left overnight could have somehow tripped the “Waste Ink Tank Counter”.
 
# 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 confirmed the 1400 USB Port is not tripping the Windows 7 Device Manager with any hardware changes. This indicates that the Logicboard is not sending any communications to the Windows7 USB Port.
# If the Logicboard will not power up the USB Port, then there is a Hardware failure / lockout.
Tech A.
 
# next to teardown 1400 & attempt to diagnose the fuse, Waste Ink Tank & Power Supply.
 
# the fuse is OK.
 
# all chips & capacitors are fair visual condition.
Tech B.
 
# I removed the logicboard chassis & diagnosed the Power Supply with a Multi-Meter.
 
# With the chassis removed & unplugged from every ribbon cable except the 9 position ribbon cable that connects the power supply to the logicboard.
# The beeping sound emits in this condition, disconnected entirely from every ribbon & plug on the printer.
# 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 again when reconnecting the ribbon cable from (logicboard :: powersupply)
# 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 9 position ribbon cable terminals then questionably read AC Voltages. 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.
# With ribbon from (logicboard :: powersupply) disconnected & USB Plugged in, the Win7 Device Manager does not trip.
Review Tech B.
 
# I believe the Power supply is OK. when disconnected from the logicboard, it discontinues Beeps & reads DC Voltages on all 9 pins.
 
# For unknown reason, the logicboard is shutting down the power supply. with ribbon from (logicboard :: powersupply) connected, it beeps & stops reading DC Voltages on all 9 positions. Then questionably reads AC Voltages 4VAC, 6VAC, 8VAC on 9 terminals.
# All cases, the USB Port on the Logicboard will not power up in Windows7 Device Manager & therefore is inaccesible to a USB TTL Device such as Virtual Com Port, FTDI, EEPROM, etc… When plugging the USB Port to Win7 it should at least show up as a “Unknown device”. If it does not show up in Win7 Device Manager, then I speculate it not possible to establish any communication with the Logicboard & therefore not possible to flash any firmware or reset WIC, etc…
# Speculative the Logicboard is actually OK & that there is some kind of Firmware / Hardware Lock activated. Unable to Trip the Win7 Device Manager with the USB Port, I am out of options. It is possible a Epson Tech could reset or flash the firmware although I don’t know how if the USB Port wont show up in Win7 Device Manager.
# All other parts, boards, plugs & printheads on the printer are probobaly good. Logicboard is locked out.
