Impossibile scannerizzare con ubuntu
Dopo aver collegato la stampante (MX455 canon) via USB, la funzione di stampa avviene correttamente senza neppure installare alcun software, mentre quando cerco di scannerizzare con simple scan non viene rilevato nessuno scanner dal PC.
Ho installato anche il pacchetto scangearmp ma provando a lanciarlo da terminale per effettuare la scansione mi da lo stesso messaggio di errore del programma integrato con ubuntu: https://drive.google.com/file/d/0B9R...ew?usp=sharing Di seguito incollo da terminale il risultato dei comandi evidenziati in rosso: giovanni@giovanni-P55A-UD3:~$ scanimage -L No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). giovanni@giovanni-P55A-UD3:~$ sane-find-scanner giovanni@giovanni-P55A-UD3:~$ sane-find-scanner # sane-find-scanner will now attempt to detect your scanner.

Purtroppo la mia stampante con scanner sta in rete e non mi ricordo che passaggi ho fatto, per scannerizzare ora uso "Image scan! for Linux" simple scan non mi ha mai funzionato e i miei appunti riportano solo:
iscan iscan-network-nt ------------- iscan-data_1.26.0-1_all.deb iscan_2.29.3-1~usb0.1.ltdl7_i386 iscan-network-nt_1.1.1-1_i386 sudo gedit /etc/sane.d/epkowa.conf net 192.168.1.150 (qui ho specificato dove sta lo scanner epson) dal che deduco che devi installare iscan iscan-data e sane apt-get install sane sane-utils libsane-extras al comando sane-find-scanner devi premettere sudo se no ti dice che non hai i permessi, però strano, riispetto a lsusb c'è un device di meno (proprio 001:002 lo scanner). Fammi sapere se ti bastano le informazioni altrimenti guardo meglio cosa ho installato Ultima modifica di pigi2pigi : 18-02-2015 alle 16:06. |

Ho provato anche a lanciare xsane (altro programma per la scansione) con il comando sudo, ma anche in questo caso lo scanner non è stato rilevato. giovanni@giovanni-P55A-UD3:~$ sudo sane-find-scanner [sudo] password for giovanni: # sane-find-scanner will now attempt to detect your scanner.

Problema risolto, è bastato installare i driver dal sito ufficiale utilizzando la seconda versione più recente anzichè la più recente in assoluto.
A volte bisogna provarle tutte ![]() |
