HP Recommended
Product: OfficeJet G85
Operating System: Other

I got an HP OfficeJet G85 printer from someone that threw it away because it leaked ink on his floor. The printer is rusty and the ink cartridges are most likely busted but that's not a problem to me as I only want to use the scanning function. Unfortunately I was unable to use it with my laptop. Using the USB connection, the computer was able to detect something but it was unable to install the driver. But the laptop is a bit old and it runs Windows 95 so I thought next day I'll try to install it on my modern computer and see what it does.

 

Unfortunately it appears that the printer broke during the night. When I found it in the morning the small lights on the front panel rapidly blinked while the printer was off. I thought this was quite strange. I disconnected the printer from power and when I reconnected it it was dead. The power button does nothing and interestingly all the squares of the dot-matrix LCD light up and remain on. Also, the power supply makes a machine gun sound if you listen to it using an AM radio.

I have four questions

  1. What's wrong with my printer?
  2. Where can I find disassembly instructions for it?
  3. Apparently there was a driver CD made for the printer. Where can it be found today in physical or image form?

And fourth. Here is a picture I found of the motherboard of the printer.  I'm guessing U501 is the CPU. What are U700, U800 and U900 for?
