El Capitan and scanning, broken again...

[PinkyMacGodess]

Why does scanning seem to be the hardest problem to fix after a dot one update? I had problems scanning after going to Mavericks...

Background: HP Scanjet G4050 on a USB hub. Downloaded the 'new' drivers from HP after the scanner wasn't working after pushing the button on it to scan PDF. (Their software package is for Mavericks, but dated October 28, 2015.

After I push the button, the image capture app pops up, says 'waiting for scanner', and then pops up a 'problem communicating with the scanner' message. In the upper left, it shows the scanner, and then it disappears (The device count shows '0'). By unplugging and plugging the USB connector, the scanner will appear in the app, and then it disappears again.

Strange thing is that in System Information, it shows in the USB section. It's still there, it just keeps disappearing in the app, and is therefor inaccessible/unusable...

The problem I had under Mavericks was that the scan would look 'torn', or smeared when I printed it. The preview would look fine. This, under El Capitan, is new behavior, having the scanner play peek-a-boo...

I'm going to take a trip through Console and see if the tea leaves point to anything useful.

I don't scan a lot, but this constant breaking of that function with every update is becoming ridiculous...

Can the G4050 scan a photo/document straight to a file without the need for that image capture software? Is that image capture software from HP or ?

Reason I ask is because like you I had difficulty scanning with my HP Photosmart 5510 with El Capitan. Reinstalling the drivers fix it. However nothing has changed moving to 10.11.1, still works fine.

However I don't use any of HP's software, aside from the HP utility which I never open. The scanner gives me the option to Scan to a File which just pops up in my Documents folder.

Thank you very much for your reply. Apologies, that is the Apple Image Capture app in the Applications folder. When I hit the button on my scanner, that's what pops up. I don't think the HP software works anymore.

The Image Capture.app is version 6.7, and since all of my systems are up to El, I can't tell if that app was updated in the upgrade.

It's puzzling that it's possibly the TWAIN driver that is 'disappearing' the scanner. I haven't gone to console yet for the tea leaves.

I sure hope I can use this scanner. If not, this will be the third scanner that I have had to toss because of an OS X incompatibility. Oh, and with HP going through a 'Do It Yourself Lobotomy', it's not looking like support is going to be available.

YIPPEE!!!

I do wish that there were more onboard USB ports. I have a peecee that has 8, with 2 internal. My iMac has... 3?

The console tea leaves were not at all helpful, or the tea is darker than usual...

Try VueScan (http://www.hamrick.com). I have used it since 10.4/Tiger on a PowerBook through the latest El Capitan release on a nearly 5 year old MBP & it is bullet-proof. It is not free but neither are new scanners.
