Cannot Connect Canon LIDE 400 to GIMP

]I want to be able to directly scan to GIMP.

All seems in order, but I cannot get it going.

All the drivers are up to date.

CanoScan LiDE 400 Scanner Driver Ver.1.00 (Windows)
File version: 1.00
Thanks for your guidance.
Release date: 03 August 2018[
This file is a TWAIN-compliant scanner driver for Canon color image scanner.
#Installed with the scanner set up

#scanner is working fine.

Does that mean the scanner works with other applications?

Looking up the scanner specs, soon came across problems this an Amazon customer. https://tinyurl.com/y6anxwjb

That reports faulty software from Canon.

I know that there are issues with the twain plugin with Win10 / 64 bit Gimp 2.10 (does not work) but AFAIK no problems with Gimp 2.8

----------
edit: Absolutely no consolation but I pulled my ancient Canon LiDE 30 from the junk box (from 2004 -ish, so old I can not even give it away) Plug into linux Kubuntu 18.04 / Gimp 2.10.12 (xSANE plugin) Works fine https://i.imgur.com/LMMGgJz.jpg

In response:

It works fine with their supplied app. So far I have not had a needed to try it with any software.
GIMP is my first attempt.I have not had any problems with their app.

I read the Amazon review. What may have been the problem was my start- up problem.
The scanner worked okay with a short usb cable but not a long one. It needs to be close to the source.
I purchased a power hub. I plug the scanner into it then route that output to the box. No problems since then.

Given the comment about Windows 10 compatibility I will post a question to the 10 Windows Forum. I tried it first looking for hits on the LIDE 400 but none turned up. Posing the question as a driver issue, xSANE plugin,
such a question may bring some help?

Do you think I could get GIMP to recognize a digital camera (also Canon)? Would I need different drivers? Different procedures?
.
I have an old Linux machine. If push comes to shove I could use it, but it is so old I may need to run it under an older version of GIMP? How would that work?

I also have a HP entry level sheet fed scanner. Is it possible to connect it directly to GIMP?

How would that work under Linux? The project is so large that it might justify a new Linux machine?

Oh. I need the flatbed for documents that may not survive the sheet-feeding.

Without considering GIMP they two side x side work well.

\I forgot. When I first started I may have had it working under NAPS2. https://www.naps2.com/
I cannot recall right now but will give it fresh try if that info ins needed.

Thanks for any thoughts.

PS.

My goal, whichever way I get there, is setting up some sort of paradigm for enhancing contrast and legality of hand written narrative on 3-ring notebook paper. I have maybe over 10,000 pages like this that I want to digitize.

This archiving is a one-run for me. The scanner works fine for my everyday stuff so I do not need to changes out the scanner for that work, but would a different entry level scanner connect with GIMP and W10?

If it works with other applications but not Gimp then most probably the Gimp twain.exe plugin not working . That Xsane plugin is a linux plugin not Windows.
What version of Gimp are you using? Is it really Gimp 2.8? There are versions of Gimp 2.10 that definitely do not work, Partha 64 bit for example. The Gimp twain.exe plugin is 32 bit and very old.

While I had my old LiDE 30 out I tried it in a Windows Virtual Machine (XP / Gimp 2.8) not working there. Gives the 'unable to communicate' message even with the Canon utility. Guessing a (virtual) USB port issue, which might lead back to your power USB hub providing power but not compatibility with Gimp. I must have had it working one time, long ago, when I used Windows on a real computer.

Two parts to that, as a capture device , same as the scanner it depends on the Windows TWAIN installation so chances it does not. As a storage device to transfer images you have taken it should show as another drive in Windows.

Quote:I have an old Linux machine. If push comes to shove I could use it, but it is so old I may need to run it under an older version of GIMP? How would that work?

Depends how old it is, The scanner support is mostly built in to the linux kernel but you need the sane and xsane packages for Gimp. Which Linux is installed?

Quote:I also have a HP entry level sheet fed scanner. Is it possible to connect it directly to GIMP?

That might actually be a better bet than the Canon. Still relies on the Windows TWAIN installation. Check if there is Win10 software for it. Might be more compatible than Canon.

Gimp might not be the best application for this. One page at a time? The software that comes with the scanner might be quicker on a page-by-page basis. Then as a suggestion use Gimp 2.10 in Win10, get the gmic http://www.gmic.eu plugin which has filters for improving scan page quality.

I will need to piece this out.

Not sure where I was before but my current GIMP is 2.10.12
I was not aware that there are different versions under this?
Am I okay with this version?

I think it as been a year plus or minus since I last updated the Ubuntu machine. I rarely use it and mostly keep it for fall back and sentimental reasons. It is the first / only computer that I built from odd-bits. It runs on a P4D, with I think 2gig RAM. Not much in today’s terms. Do you think it would be adequate for a quick test?

I will try the HP with GIMP in the next day or two, then report back.

Sorry I was not very clear on my intent with the flat bed scan and the handwritten pages. I am still at a design level, with minimal skills for digital imaging.

All the papers are in three-ring notebooks. There certainly will be variability in the ink, density, etc. I speculate because of the variables that I may need to adjust the parameter as I march through each note book. Maybe not? Just set up a B&W scan that will cover all cases?

I plan to use the HP for the majority of the work.

If I hit snag or something needs profound adjustment I think setting that up in GIMP will be better than the HP app. I have hard time with both the HP and Canon apps because of font sizes and colors: I do not see so well and I am frequently at odds with ambient light too.

Macros could be great production helper.

My thoughts have been that as I march through the scans I could set up values that will cover a range of cases, then keep them on the ready for the next encounter with a similar one. Say something like tweak up the brightness, slightly reduce the contrast, alter the RGB values…..

I have done a couple of tests and the modification will not likely be severe or involved.

From other work I have a small collection of docs that would fit into the photo-restoration catagory. It may just be that culling out the problem doc as go then do them later as a separate task may be course?

My goal is getting rid of the weight and bulk. Right now I am over the 10,000 mark with other docs. I have stack of maybe 500 or so to finish this leg. There are other legs, but next I want to start getting a handle on the best track to deal with the fifty three ring notebooks.

I need to run. Way past time for dinner.

Thanks for any and all suggestion and your guidance.

I will try and keep short. Your first post has Gimp 2.8.14 installed. Changed to Gimp 2.10.12

quote... "but my current GIMP is 2.10.12 I was not aware that there are different versions under this? Am I okay with this version?" If you got the windows installer (currently gimp-2.10.12-setup-3.exe from http://www.gimp.org then that should work, but I do not have any way to check it with a scanner. My regular scanner is a Brother I use in linux.

quote.. "been a year plus or minus since I last updated the Ubuntu machine".. Ubuntu has versions as well, Unlikely to be the latest. You will be using a Gimp 2.8.x (x depending on Ubuntu version) Install sane and xsane packages. Plug the Canon in see if it works. If you look here: http://www.sane-project.org/lists/sane-m...ml#Z-CANON it is supported. Worth a try.

quote..."Macros could be great production helper." Gimp does not support Macros. If the scanner is recognised by Gimp you can bring up the scanning dialogue with a shortcut key, equivalent to File -> Create -> Xsane -> 'your scanner'

quote..".I have stack of maybe 500 or so to finish this leg".. Generally, the usual advice, whatever OS, scanner, version of Gimp. Save your work frequently

I put the question to the 10-Windows forum participants
https://www.tenforums.com/drivers-hardwa...-10-a.html
No takers yet.

I am confused on the SANE. Is it cross-platform or only for Linux?
https://en.wikipedia.org/wiki/Scanner_Access_Now_Easy
From this it sounds like it will work in Windows !0?

http://www.sane-project.org/lists/sane-m...ml#Z-CANON
This is helpful,I found

CanoScan LiDE 400 USB 0x04a9/0x1912 Complete Support up to 4800DPI (Note: does not have less than 300DPI support) pixma
(0.24.1) sane-pixma\\

Thanks for your comments.

You could look at this https://windowsreport.com/cannot-communi...indows-10/
7 possibilities for a fix. Never very convinced by the usual MS "reinstall everything" The bit on two-way communication sounds feasible. There is an 8th option - despair.

Not Windows. Back in post #4 (x)sane only Linux (or OSX) All those references require a working SANE or a connection to a server running SANE. There is/was a Windows twainSANE - never been updated since WinXP chances of working are zero.

Not looking very promising for Windows.

What happened to your old linux machine (which linux version? ) As an experiment, pulled the ancient LiDE 30 from junkbox (again) fired up ancient laptop (c.2007, I keep next to junkbox for usb hauppauge video grabber).

Installed Sane and xSane. Plugged scanner into computer. A reboot for linux to see the scanner (which might be worth looking at) ..and it just works.
