Question about HP 4570C Flatbed Scanner

1 Answer

HP 4570c scans totally black or bluish-green with vertical bars

Problems started out to be intermittent and I could solve it by unplugging the power source for 5 - 10 minutes and then restart the scanning. Now the unit will only scan very, very dark or totally black from a white document. I have been to the HP website and followed suggestions they offer, including the "homing" procedure outlined on this site. I have installed the newer version 2.0 software, still no improvement. I have ruled out electromagnetic problems because the scanner has been in the same location since 2004 and nothing has chaged at my desk. I even tried installing the software and connecting the scanner to a completely different model and brand computer; same problems. Great scanner, very reliable and good quality, until now.

    I too have had this problem since having to reconnect my scanner after moving my computer from one end of my office to another. I have several times tried reconnecting it following all of the directions to a "T" both in the users manual and online troubleshooting - all to no avail. I even cleaning the glass following the directions online. I had no problems whatsoever with the scanner previous to this. Haven't been able to use it in several months. Would appreciate any and all suggestions. Duendi

    Exact same issue. Scans full black with vertical bars. Very annoying.

    Have never had a problem before now. Now, no matter what I scan, be it text or picture, the result had been the bluish-green, now all black. Have tried reinstall, and all connections are fine, but to no avail.

    At one point, I noticed some shadows on preview, but later with scanning or previewing, the entire page scanned came out pitch black.

It could be one of two things:

1) The scanner isn't registering black or white during the initialization processing depending on what color it needs to get it started.

2) The CCD unit in the scanner could be failing which could explain why it was only working briefly before getting worse.

Light bar stops too soon

I assume you are using this with a computer. One thing comes to mind that relates to software. You should be able to do a preview scan of the whole scanner bed, then move the frame to the area you want to scan only, sort of like cropping the picture. If those crop borders are set to less than the whole document, you will get this kind of scan.

Now if that isn't the problem, the scanner likely has a electronic issue unless the scanner has had a nasty fall. If you want to really explore deep and don't mind if it doesn't work afterwards, turn the scanner off and unplug the power. Open it up just enough to access the optical unit and see if it will move the entire length of the scanner without binding where you experience the end of the scan. Go rather slowly and gently so you don't strip the toothed belt if it has one. You will feel a wierd sensation and some resistance as you move it along which has to do with the stepper motor and that's normal. If that works, it's likely it failed on it's own. If it binds where the scan ends, you'll have to investigate whether it's due to a rusty rail (hope not!) or some other obstruction.

Good luck!

Is the glass clean?

Often the plastic will out gas and it will deposit a film on the glass. You might have to open it up and clean the inside of the glass with window cleaner. There is also a mirror in the scanner head. That can get fogged up too (in fact it gets fogged up more frequently than the glass plate). The trick there is to find the mirror below the slot and then clean it with a q-tip that has been dipped in alcohol.

Scanning bar light

Do you mean the green power light? I have the same brand and a similar scanner, and the light does always stay on. I think it is a normal function of the scanner. It may not be a good idea to unplug the scanner. I am going to be a bit more research so that we can both be reassured that this is normal.
I'll get back to you.

Color problem and inacurate scaning

I solved my problem by simple re-boot. Unplug scanner power and USB for several seconds then replug. This solves a large percent of such problems. I wasted a lot of time before I did this. mike123456
