Wireless scanning on Epson SX535 [SOLVED]

[marcusadamski]

Hello there,

I was previously running Lubuntu 20.10 and my Epson SX535 was immediately picked up for both printing and scanning. I've just switched to Mint XFCE 20.1, and although again I can print wirelessly, scanning is an issue.

simple-scan does not find the printer.

I've connected via a usb cable, at which point the simple-scan can detect and successfully scan. So the drivers are available, simple-scan just cannot detect the printer when operating wirelessly.

Please note my printer's IP changes, as it connects to a DHCP wireless router.

Thanks for any help,
Marcus

Using the wireless connection, please provide

Code: Select all

avahi-browse -rt _ipp._tcp

Code: Select all

avahi-browse -rt _uscan._tcp

From the USB and wireless connections, please provide

Code: Select all

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).

Finally, using a USB connection:

Code: Select all

$ scanimage -L
device `epson2:libusb:003:004' is a Epson PID 0891 flatbed scanner

Thanks for your help,
Marcus

The SX535WD appears to have come on the market in 2011. urf= tells us it has AirPrint, which is why your printer was auto-setup. Unfortunately, it is too old to have AirScan. That means there are only two ways of scanning:

• Via SANE's epson2 backend (driver).

• Via whatever is offered by Epson.

Your USB connection is using the epson2 backend but the networked device is not. However, Lubuntu 20.10 seems capable of using both connections. This is quite possibley because the Lubuntu version of sane-backends is newer that what Mint 20.1 provides; version 1.0.31 versus 1.0.29.

https://launchpad.net/ubuntu/+source/sane-backends is maintained by a SANE developer. It would be interesting to know whether it does anything for you. I think you need libsane1 and sane-utils packages.

Hello Brian,

I contact the Ubuntu link as you suggested, but unfortunately I didn't get much help. First I was told I cannot be helped because the question involved Mint. Then after explaining I was just looking for help in understanding if the version difference between .29 / .31 would have any impact on the wireless scanning, I was told to look at the change logs...

Anyhow, looks like I've solved the issue with a prod in the right direction from you. Looking at my installed packages, I noted sane-airscan was not installed by default in Mint 20.1. Once installed, my scanner was picked up and worked!

Thanks for pointing me in the right direction,
Marcus

Hello Marcus,

Firstly: the outcome is splendid.

Secondly: I owe you an apology. I gave two ways of scanning in another post and completely forgot that sane-airscan was a third possible way. Let that be a lesson for me! You did well to follow your investigations.

It would be really useful if you would provide the outputs of

Code: Select all

scanimage -L

and

Code: Select all

airscan-discover

TIA.

Also, please do not forget to mark the topic [SOLVED].

Hello Brian,

No problem we got there in the end. As requested:

Code: Select all

$ scanimage -L
device `airscan:w0:EPSON Epson Stylus SX535WD' is a WSD EPSON Epson Stylus SX535WD ip=192.168.0.80

Code: Select all

$ airscan-discover
[devices]
  Epson Stylus SX535WD = http://192.168.0.80:80/WDP/SCAN, WSD

Thank again,
Marcus
