Scanner error "No Devices Available" -- HP Laserjet Pro MFP M28w - USB on Desktop PC

English Hardware
#1

It worked once from Simple Scan, then nothing after. “No scan device found” by any application I have tried.

hplip, hplip-hpijs, and hplip-sane are installed. Did the “hp-setup” as root when initially setting the unit up.
I put in ‘sane-backends’ from YaST hoping it would help ----- no dice.

Driver hpaio is shown for scanning.

Hewlett-Packard HP_LaserJet_MFP_M28-M31 at hpaio:/usb/HP_LaserJet_MFP_M28-M31?serial=VNB3D14208

YaST finds the scanner.

Simple Scan, Skanlite, and xSane Scanner Tool do not recognize the scanner. Message for all 3 tell me “No Scanner found”.
I even tried loading in VUEscan from the web, and same there, “NO scanner Found”

“hp-toolbox” from a terminal offers nothing I can see to get the scanner recognized by the applications.

I’ve been all over HP’s support and scanner information for this MFP unit. No real help so far.

#2

Does /etc/sane.d/dll.conf contain an uncommented ‘hpaio’ entry?

Does ‘hp-scan’ work? Try executing from a terminal window.

#3

Yes it does. That is the only thing uncommented.

That worked today AND every other scanning tool worked TODAY! I think I am going loony!
We’ll see what happens going forward with the HP Desktop scan apps

Unfortunately on the Toshiba laptop ‘hp-scan’ finds the scanner, goes through a bunch of time waits, then comes back with ‘Scanner Busy, Quitting.’
The YES to your #1 question applies for the laptop as well.

The scan apps are all ery slow except for the VUEscan which is NOT freeware. It is blaziong fast.
Gonna look at the l;plugin for gimp, but I suspect it will only scan as an image, instead of PDF with no OCR capabilities.

Anyway, thanks again for being there with a response.

The laptop scans now too. I only checked from a terminal using ‘hp-scan’, so I assume it will work over WiFi to the scanner with GUI apps as well.

That is good news Bill! :slight_smile:

Not sure why that would behave differently, except sometimes USB3 ports don’t play nicely with scanners/drivers.

No, I think Gimp can support PDF as well.

Glad to have been of assistance.

Thanks for the update Bill. Yes, network scanning should work as well (so long as the printer function is configured and working first).
