Question about HP PSC 1510 All-In-One InkJet Printer
When I open HP Scan in order to scan something, an error message reading, "Unable to connect to HPAIO TWAIN data source". The scanner is not broken because it makes copies fine. If i press "start scan" on the printer, the power button just blinks for about 20 seconds and then stops. What should i do?
'Twain' only means 'Technology without an important name', as this is refering to your printer/scanner, i would suggest that you disconnect the printer and remove any driver from Add/Remove programmes. Re-install printer software/driver and re connect printer when prompted and if possible in a different usb port, if that's how it's connected. If the problem persists and the pc is unable to communicate with the printer the fault will lie with the hardware. Hope it's only a driver glitch.

I have seen your message stating that "Initialization failed - Unable to acquire TWAIN-compliant device" error is received when trying to connect USB-Parallel type to your Laptop.
Well, Printer Panasonic UF4100, recommends to use only " Printer/Scanner Interface as Bi-directional Parallel (IEEE1284) " means you need to use Parallel cable to connect Printer to the Computer/Notebook. You may receive some communication error messages if you are using a "PORT REPLICATOR CABLE"( USB TO PARALLEL connector). The error message that you have received is related to the communication error. Futher, if you use same USB- Parallel cable for long time the Printer Hardware functionality might go bad, since Printer memory gets confused and will not read or detect the Cable , since it is not a cable to use mentioned by Panasonic Manufacturer.
Let me tell you, general functionality of Printer like Printing would work even if you use USB-Parallel cable. But it is not a case with Scanner and Fax functionality.
Hence, I recommend you to use only Parallel cable to connect your Printer to the Laptops.
I hope that this will resolve the issue for you.
