Hello, I'm sorry, but the scanner doen't work any better. The error occures sometimes after one page, sometime after 20 pages, and I can see no reason, why the scanner does work sometimes and does not work at the next time. The error is not predictable.
Maybe the scanner is waiting for a signal from the computer or from the electronics. When the error occured, the computer gets a time out and gives the I/O-error. After that, there is no communication possible between scanner and computer. After about 5 minutes gets a time out and makes a reset, so the scanner is still running. After that the communication between scanner and computer is possible again on the same USB-adress. Any ideas? Does anybody know something about errors of these HP-Scanners or about errors of the USB module?
