Question about Heidelberg Linoscan 1450 Flatbed Scanner

2 Answers

Scanning lines I have a Heidelberg 1450 scanner that has begun making these scanning lines in the images that look like scratches. Can this be repaired or is it time to start looking for a new scanner?

    Can you advise me on what it is that is causing these dark lines? and if the lamp is the culprit, how to get to the lamp?

  • Stuart Rome Jul 04, 2007

    I sent along a photo of a scan with the long straight dark lines that follow the length of the scanning bed - do you need to see them again/ They would show you which kind of problem I am having and narrow down the cause and solution.

  • Stuart Rome Jul 04, 2007

    here is an example of the black streak lines following in the same direction of the scanning bed.

  • Stuart Rome Jul 04, 2007

    I'll try opening it up today and see if I can clean up the problem. I have also been looking at the Epson V700 scanner to replace this if the scanner is at it's life's end. What do you think of that unit as a replacement?

    Opening this scanner up seems beyond me and the sites you directed me to were for the HP scanners???

Stuartrome, Noggin gave you some very good suggestions on how to solve your problem. Allow me to add my opinion. Although Heidelberg offers very good scanners, I think over the years the quality of their customer service has dropped. It really depends upon which customer is spends more money. (fact of life) I think for the quality of the final "product" you are trying to achieve, it would be best to invest in another more current model. I would stay away from discontinued models or those close to "end of life" cycles even though they are cheaper. This link gives you some reviews HP, Epson, Microteck, not a lot, but at least a start for selecting the model that meets your needs. These are "high end scanners". http://www.imaging-resource.com/SCAN1.HTM I hope this answer helps to solve your problem. Also they may be several buyers out there who might need your older machine for parts or even for personal use. Check that out to minimize your costs.

Check this link for a bit of info about the scanner. http://www.hwkb.com/Uwe/Forum.aspx/scanner/973/Heidelberg-Linoscan-1450-sparepart-and-driver-for-Windows I agree: Heidelberg no longer support the model so you will have a lot of trouble finding spares - I searched a lot and the only place you can find these now seems to be e-bay. I would be tempted to say get a new scanner, but it is just possible that replacing the lamp if you could get one or cleaning the inside may help, but a scanner usually only has a few years life in it. Just possible the lamp is standard, if you can get to it and get a part number from it, perhaps we could find one online. Hope this helps :)

    If the lines are not the full length of the image, they are probably caused by dirt on the glass screen (possibly on the inside).

    If they extend the full length of the image are the lines exactly parallel, as could be caused by a fault/dirt in the light sensor array, a fault/dirt in or on the lamp or it's mirrors.

    If they meander backwards and forwards a bit, then the problem is likely to be in the control electronics, unless something inside is actually loose and moving around, which should probably be visible or audible with a little shake.

    What sort of width are the lines - fine and crisp, straight and parallel, unevenly spaced suggests dirt or bad mirrors are the most likely culprits.

    a bit wider and sharp suggests the sensor array or very bad mirrors, a bit wider and blurred would suggest possibly the lamp, possibly the processing unit.

    I couldn't find any specific info on getting inside your model anywhere, but check this link - it describes excellently how to check and if necessary fix all of the above issues for a similar HP scanner. The control electronics are possibly wildly different, and for sure the way to open the case will be different, but most of the rest should look very familiar, scanners are pretty much the same;
    http://willshak.com/scanner/

    If you can't figure out how to get into the scanner, post me some photos and I might have some ideas. If you get inside and need some help, also post some photos.

    Hope this helps :)

    Ok looks definitely like a problem in the carriage. Difficult to say for sure if it is mirrors, bulb, sensor array, or just dirt, my guess is the sensors, but you can check and clean all of these at the same time anyway - any luck opening it up yet?

  • Nigel Ridehalgh

    PS it looks fixable

    The opening up procedure will certainly be different from the HP scanners - post me photos of yours from several different angles and underneath and with the top open and I can hopefully figure it out figure it out - the general inside layout for the HP scanners I would expect to be very similar.

    i don't know the Epson 700 myself - I have an extremely old Epson which is not great, but encouragingly still working, on this link for the 700 is probably the most detailed product review i have ever seen for any product;
    http://www.photo-i.co.uk/Reviews/interac...

    He explains and tests everything, although it is a little hard to say for sure if he liked it or not - most other reviews I found were pretty excited about it.

    My impression is that the 700 will be a good scanner, but if the price is not too much more then it is worth getting the Epson 750 if you can.

    Hope this helps :)

  • Nigel Ridehalgh
    Nigel Ridehalgh Jul 04, 2007

    PS the price difference at the moment is around $240, so i think the E700 is probably better value, the price gap may close up later though.

I've cleaned the glass and still have a black line on the image


Scan a document in 300 dpi in full width. Check where the line appears in the image. For example if the black line appears at vertical position say 1900, then it means the dirt is at 1900/300 i.e., 6.3 inches from left. Clean the area thoroughly. Check if any pin had created a scratch in the glass. At different contrast levels, if the line appears different, it is definitely unclean glass. On the contrary, if the line appears constant at various levels of contrast, then it is possible that scan module is faulty.

Canon DR-2050C Scanner gets verticle line down image


I have the same issue with mine and there are 2 image sensors on this scanner. 1 in the back that you will see when you open the front that has a meteal shield covering the top half, and one in the fold out front that faces the inside. These are the "glass" sections everyone is refering to. Problem is, they are plexiglass, not glass and mine has a tiny scratch in the lens that is causing the line. This could be your problem. find the lens and use a LED flashlight to inspect your lens for scratches. If its scratched like mine, the entire module has to be replaced to fix it. The canon part number is MH7-7038 and they range from $125-$160 if you replace it yourself. The one in the front is easy to do, but the back one is a little tricky. Hope this helps. E.

I am getting streaks and not a clear scan


This could be because your lens is scratched or dirty. The easiest way would be to wipe clean the screen.

Line on far right of scanned documents


Hi,

Most likely the scanner has dirt on the glass that is over the imaging array or the glass may be scrached. If the glass is scratch, the imaging CCD array need to be replaced. If you do not scan the rear of your documents, you can swap the upper with the lower in the case that one is scratched.

The imaging array are the green long bars, one at the bottom of the paper path halfway inside the scanner and the other is above it. Look closely for a small spot of black toner or dirt stuck
on the glass. Take a soft cloth, wet it with water or alcohol if needed and clean the glass.
Pass you finger over the glass, try to feel if all of the toner or rubber residue has been removed.
You might try looking at the specific area were your documents image is getting the line. It will
help you pinpoint where you should clean. CAREFULL not to push on the glass as this
might break it. Hope this helps.

Streaks in image scanned by Canon DR-2580C Path-Through


The staples cannot reach the sensors. They could have scratched the glass above the sensors. Clean the glass with IsoPropyl alcohol. Try scanning a few images to find if the scratch marks are on the same place on all images. Once confirmed that the glass is scratched, you can change the glass. You need a technical expertise to change or call service staff.

Upgraded to MAC OS X; is there a compatible driver?


This scanner was released back in the late 90's, before Os X was released. Heidelberg discontinued support of all but their high end Nexscan scanners. So unfortunately, newer drivers were never made for this product.
