Canon LiDE 400 - Can Not Scan at 4800dpi

izzy891 — Sun, 28 Jan 2024 20:23:34 GMT

Hi there,

I recently bought the Canon LiDE 400 scanner as the resolution goes up to 4800. I need the maximum resolution as I want to blow up some antique hand painted artworks which are tiny. I have tried downloading the IJ scan utility software and changing the settings in drivers to allow large image scanning (found this in a previous post) but the resolution is still fixed at 600dpi. I am on a macbook pro. Is there another way and why can i not scan at the full resolution?

Thanks

Hi izzy891,

Please follow these steps:

1. Open the IJ Scan Utility Lite.

2. Click the Settings button in the lower right corner.

3. Click Driver in the menu on the left side.

4. At the top of the right side, please select Custom in the Output resolution box and enter the desired DPI.

Hi Patrick,

The Custom option for Output Resolution doesn't appear in the Windows Software. Is it located elsewhere or just not available on Windows?

Hi,

Please click HERE to open the page you will need to open the scan gear and driver settings to change the output. The page that opens will have a link to how to open scan gear and scan gear (driver settings). Check the advanced mode tab on the ScanGear (Scanner Driver) Screens page.

If you have issues, you can always use the paid Vuescan app which will give you full control over the scanner.

I have just bought my LIDE 400. The max dpi I can select is 600. There is no "Driver" option on the left of the settings page. How do I scan at 4000 dpi.

Hi,

What version of Windows or MacOS are you running?

We look forward to your reply.

Windows 10.

I think I have since discovered the following after a phone discussion and trial and error.

1. Selecting "Settings" on the IJ Scan Utility first screen does not allow me to select greater resolution than 600 dpi for a photo, however small.

Selecting "Scangear" on the first screen allows me to enter (not select) 1200, 2400 etc into the resolution, but when scanning I am then limited by the memory required - i.e. the product of image size and the resolution - in the example I was using - a print approx 2" x 3" - to 1200dpi, getting an error message when using a higher resolution.

This limitation may be due to a limit in the software or the available memory on my laptop.

Is the above correct? If so, would having more memory on my laptop help? I did close all other apps and restart my laptop before trying.

Your link doesn't actually work now. I just purchased a CanoScan LiDE 400 so that I could scan at 4800dpi on my Windows 10 computer. I was using PhotoShop but the windows TWAIN drivers don't go over 600dpi anymore. On Windows XP 32bit systems I could scan at 4800dpi no problem, now on the Windows 64bit systems it's like pulling teeth! So far, my two old CanoScan 8600F and the 8800F scan things better at 600dpi. At least with those scanners I can adjust the brightness and contrast myself, and there is a better depth of focus. On this 400 scanner if the image is 2-3mm above the surface of the glass, it's blurry, no a problem for my old scanners. No options for brightness or contrast with the IJ Scan Utility, and there is no lite version for Windows that I can change up the dpi setting. This 400 might be smaller, lighter, and faster, but it's been dumbed down for college students and is useless for graphic artists using Windows 10. I'll be returning this new scanner to Amazon if you guys can't give me a straight answer how to scan a full 8.5x11 sheet at 4800dpi on windows. I've got the memory for it, and if I scan it into PhotoShop CS6 I can save in a large format file type.

Where is the ScanGear install for Windows 10?

The IJ Scan Utility does not install ScanGear Starter and the link I found is for Mac OS.
My laptop doesn't have a CD drive.

This link does not work:

We see that link is from a post from a couple years ago and may be outdated.

Please try this one and let us know how it works out: https://canon.us/425mDYA

We hope this helps!

You might have mentioned that the ScanGear utility was one of the main options of the IJ Scan Utility and not a different application. I made an ISO file of the install CD and ran it from my server on the laptop. Looks like the full platen scan is limited to 1200dpi and if you want 4800dpi you are limited to a small part of the full page, maybe 1x1 inch.

The old 8600F and the 32bit software would let you scan a full page at 3600dpi directly into PhotoShop, I only see 600dpi for that now. Your CD has a TWAIN driver folder but I'm not seeing how to get better than 1200dpi from a full page. If I could do it 10+ years ago, why can't I do it now?

the limitation of the ScanGear software is apparently memory. But oh well. image cannot exceed 50,000x50,000 pixels or 4GB. so the biggest image I was able to scan at 4800 DPI is 6.7 inches x 9.20 inches which is just below 4GB in size for a JPEG. I shouldn't have any limitations because my PC has 128 GB of RAM and 80 TB of storage. In order to get to 4800 DPI, you have to use ScanGear. you have to go to the settings for ScanGear and select the checkbox for "Enable large image scans". Once the setting is saved, go to ScanGear to scan the image. TYPE 4800 into the resolution box (don't use the dropdown arrow). Set max scan to 6.7"x9.2". Then you will be able to scan. that means if you have a picture bigger than that size and you really want 4800 DPI, you will have to scan multiple times and then use software to put them together like Photoshop. for some more details... the 6.7 inches x 9.2 inches is the output resolution. the input can be the full size of the glass. so you can put a 8.5 inch x 11 inch paper on the glass and scan. but the output will be 32162x44160 pixel resolution.

Pretty sure I had that checked, but I'll try it again.

My biggest problem now is that images 2mm off the surface are not in focus.

Re: Canon LiDE 400 scanning at 4800dpi

onlysublime — Mon, 29 Jan 2024 07:00:21 GMT

yeah, you have to press the image to the glass. maybe place a book or other semi heavy object on top of the image?

Re: Canon LiDE 400 scanning at 4800dpi

CraigJohnson — Mon, 29 Jan 2024 20:19:12 GMT

I did not have the "Enable Large Image Scans" checked, must have been on my first installation.
I will test that later. Here is the problem with the image focus on the CanoScan LiDE 400:

Here is the same coin with the same settings from the CanoScan 8600F:

I scan 20 coins to a page in a page holder and flip them, then run a program I wrote to break them up into single coins. I have over 1000 to do, so I was hoping this new scanner would be faster and better. It's smaller, lighter, faster and worse.

onlysublime — Mon, 29 Jan 2024 20:37:55 GMT

I'm only going to guess that this scanner wouldn't work for you. I read somewhere that the reason the scanner is so thin is because of the scanning system they use and that this scanning system requires the object to be right up against the glass. Again, I'm only guessing so best of luck. Let me know how it turns out.

CraigJohnson — Mon, 29 Jan 2024 22:35:13 GMT

I'll keep the scanner because it works just good enough to scan a full color page from an RPG book so I can blow a gaming floor plan up to 36x48 inches at 300dpi. Having a 36in printer helps. It's not useful for cataloging the coin collection though, so I have to keep the 8600F and 8800F scanners. Guys in the coin club might want to borrow them.
