Question about Canon CanoScan 4400f MultiFunction Color Printer

Open Question

My scanner is not scanning dark enough. I am scanning childrens' drawing with handwritten sentences. The sentences show very faintly. You can't read them. And the pictures are washed out looking. This scanner has been hooked up to a Dell running Windows 7. It seems to open into Picassa. This scanner was set up by my technicians. I have no book with suggestions. Can you tell me what settings to check or why this could be happening?

SOURCE: stop working

The covers are pretty easy to remove and access print catridges once you know how. Unscrew screws as they become available, 4 on back then two on each side then 4 on top. the balck plastic front bezels pop off as do the grey side panles. Try pulling out and up from the top. This can be a little tricky but I have not had to be too brazen and have not broken any panels. I am pretty sure that clicking sounds indicates broken parts and a trip to the repair shop. Basically the lock to keep the heads covered is not disengaging.

SOURCE: Canon mp610 scanning problem

The readme says that some USB hubs have an issue.

I was having problems and was connected via a hub. I removed the hub and connected the printer directly to the back of the PC and voila scanning is all good.

ALex.

SOURCE: Canon Pixma MX850 won't scan - says 'set the pc to start scan'

Do you have more than one PC connected to the scanner? I have both a PC and a Mac connected to it, and I think my scanner is trying to connect to the Mac, which requires image capture software to be installed, rather than the PC. Don't know how to tell it to go to the PC, though...

Change scanned doc. to go to word not pdf


Depends on the document. If there are images and the type is handwritten. First scan the type as OCR scan so it scans only the text, a new window should appear for editing...nothings perfect...
Then scan the page with the images as a whole as doc file. Hope this helps, not all scanners are built the same, just have to read the instructions and features before buying.
Another way to scan to word is right from the MS Word Application. View the video to learn how.

Why does my Canon Mf 8380 scan anything handwritten very faint and non legible


Is the handwriting black ink? Colours come out poorly on most scanners.
You need to increase the contrast when scanning handwriting.

We have a Canon DR-9080C scanner. When scanning in Duplex on pages with data on both sides, the back side of each page is coming out unreadably faint. The header and any overall large blocks of black on...


The Canon DR 9080C is a 'contact' scanner. There is no optical lens, instead it uses a technology called "Contact Image Sensor' or CIS. The page to be scanned must be close to the glass for a proper image. This is achieved by a full-length rubber roller just above/below the scanning module. The roller is spring loaded and in case it gets stuck, there wont be enough pressure on the document to keep it close to the glass. ensure these rollers are moving smoothly and if required clean them. The rollers are on the opposite of the Scanning module.

What do you mean by (ocr) on an x2670


Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic translation of scanned images of handwritten, typewritten or printed text into machine-encoded text.
These can be scanned in a word processor or other programs, then can be modified.It is software usually include with your Printer/Scanner

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response.

I've been scanning in drawings and the drawings each have some words at the bottom of the page. When I scan it, only the words appear to be recognized but not the drawing. It was working fine before, why...


may be you have written the words in darker ink and drawing might have been in pencil! scanner usually recognises dark areas and adjusts the picture based on it! make sure you darken the drawing as much as those words!

Bad contrast with scanner


Last things first: NO USER SERVICEABLE PARTS INSIDE.

That's the way HP does things. There are no rheostats or pots to adjust. It's all done electronically now, with chips and things.

You never said how it does with color or greyscale photos or drawings.

As for the RGB=(64,64,64), that's about right for the scan picture settings and the mixed (text and graphics) setting, and is particularly true for color picture settings. Have you tried using the setting for drawings (or line art), specifically greyscale drawings? Usually the greyscale lineart or drawing setting will render black text. You might also try scanning with the settings set for Text. If the greyscale drawing settings or greyscale text settings do not produce black text, try reinstalling your software and drivers.

If the contrast stays the same for all settings after reinstalling the software and drivers, and if it doesn't scan color and greyscale pictures correctly, then it sounds like your scanner is going bad.

As for the scans you've already done, you can darken the text by taking it into a photo editor, such as Paint Shop Pro or Photo Shop, and adjust the contrast and brightness to get the effect you desire.

Scans slides too dark.


maybe the slides are too dark, in other words, the pictures you took didn't have enough exposure therefore you it shows up dark.. You could always use photoshop or someother photo manipulation software to lighten the scan, same thing happens with my hp scanner with slide adapter, if it slides just show up dark, lightening it with software will help, unless it is unsaturated/shadows too dark, etc..

Hope this helps.
