    Colortrac SmartLF Ci 40

    Hello,

    There's a listing for this particular scanner in my area listed as "scanning faintly" and "black lines appearing on the scans". The scanner otherwise operates normally, I've been told. I don't have a scanned file from this machine, unfortunately. I will go and inspect it in the following days in person, hopefully.

    I was just curious if anyone of you with some experience servicing scanners like these, upon hearing this, do you have any suggestions on what things I should check for in order to get an assessment on what I am looking at?

    Would this be worth fixing or is it simply paperweight? I am guessing it's either a problem with its mainboard/image processing board or a bad CIS array, if the problem is in one specific area, but that's just an educated guess, as I have zero experience dealing with machines like these.

    Thanks.

    I should also note that, judging by the kind of business that is selling the machine, it probably has seen little to moderate use over the years. Also note that the machine is in really good cosmetic condition.

    If I were to do some guessing, I'd say it's possible that the CIS(s) & the white reference roller are dirty or the roller wrinkled. If the roller is wrinkled or will not clean, it will need to be replaced. Once cleaned you may need to calibrate the scanner with the Normalization & Stitch Target. If the enduser has lost the chart, that will add $75 to the call.

    This scanner is used on a lot of the Canon iPF7xx series MFPs so we see quite a lot of them, though they don't usually see very heavy usage.

    I could offer you something more substantial with a photo. =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Thank you for your prompt reply, black cat.

    Yes I understand, I also want to see the machine up close and see how it scans. if everything goes well I'll go there Monday evening and post my findings. The machine is sold with its calibration chart, fortunately. Does the main white roller that I saw on the service manual wear out quickly? As I said, I doubt that machine has seen heavy usage, so probably the glass on one of the CIS sensors got damaged? Can you give me an estimate for the cost of that roller so I can know how much I'll have to invest to potentially get it running again?

    Usually it's just dirt on the CIS(s) or the white reference roller, probably both (voids=dirty white reference, lines=dirty CIS). The one that I saw that was wrinkled had almost no usage:

    These units operate well and are pretty solid. Like cat stated already, just clean the scanner and the white reference roller, make sure the customer hasnt inadvertently messed with scanning presets causing the image quality issues. And if they have the calibration/auto-stitch chart, go into settings and run both of those adjustments.
    Accidents don't just happen. They must be carelessly planned.

    Hi guys,

    I am just about to head out to check out that unit. I will post my findings once I get back. Just a quick question: will I be able to find any spare parts, say like a CIS sensor anywhere or will I be stuck with a machine I can't fix due to no spare parts being availiable?

    I've taken a couple of pictures on the inside of the unit. All CIS sensors look clean, and the reference roller appears to be in good shape. The LCD works fine, I can navigate through all the menus. The paper controls operate the motor correctly. I've also attached a scanned file from the scanner. It's all complete gibberish, though some section of the actual scanned document can be hardly seen. What do you think?

    Thanks.

    Wow! Is there any of the original image? It all looks like "noise" to me.

    I've never seen anything like this on a Colortrac, but not any one of the CIS(s) could cause this sort of image all the way across. So I'm going to conclude that it's not any of the CIS(s). If you've re-seated all the ribbon cables and checked them for damage, and tried a new USB cable, about the only thing left is the scanner board. I don't see any point in calibrating, since the image is unusable.

    No guarantees, though. =^..^=
