Concur.
# 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.

I had this problem so I spoke with two experts. They said both your printhead and mainboard or out of work so they need to be changed and it costs a new printer. I sold my printer parts and bought a new one.

Hi I'm glad to contribute to this forum with the solution for the problem when you change the printhead or you flush the printhead all of the sun in the printer won't start won't turn on what I found was that the two transistors on the hissing of the logic board fail I still haven't figured out why does the printhead shorts these two transistors but once you replace the transistors the printer toner design and gives no problems. Well no problems but it still won't print because I still haven't replaced the printhead I am trying to figure out why is it that the printhead is shorting out on the board because if not it will not work and it will short the board it again I tried it twice and every time is short the transistors so I hope this help you at least you'll get to turn on the printer again still waiting to figure out how to fix the problem with the printhead I am going to try with a brand new printhead see if it does the same thing Dario Ortiz Oss..!!

It would be of great help if anybody can get me the schematics of this printer with the schematics I can probably figure out why are these problems happening but without schematic is a little bit harder I seen they call him either schematic or diagram so if anybody can get the schematics of the logic board and all the electronica parts of the printer I will appreciate it thank you DarioPcx@Hotmail.com
