My Canonscan 5000 goes through the motions of scanning a document, but then prints just black sheets of paper, no printing of document at all. I have downloaded new drivers, uninstalled the program and reinstalled it again. Unplugged all cables and replaced these. Any ideas of what is happening and how I can fix this?
The mystery is solved!!
I live in Norway and my CanoScan 5000F has worked brilliantly until it suddenly started to display a black preview in ScanGear, black scanning and to no surprise,- a completely black printout.
My first thought was that the scanner-lamp had died,- but that was strange because I hadn't used the scanner that much. I hadn't made any changes to my computer system either. The operating system (Windows XP), scanner software and drivers were exactly as before. I made a new testrun and saw the light come on from the side of the scanner and move along the platen as usual. The sound and operation of the scanner seemed to be all normal. A quick check on the internet revealed that there were many other guys out there who had experienced the same problem. Some had tried new drivers, uninstalled and reinstalled, but to no luck. I also tried the same method, but was stuck with the same problem.
I have a background as an electronic service-engineer, and this mystery really gave me a good challenge. Why did so many people experience the same thing? Why couldn't Canon answer and give a reasonable explanation to the phenomenon? What was the common factor in all these cases?
Every scanner is connected to the mains via a power-unit. Mine is European standard with type nr. PA-08E. It is labelled with output DC 12V (stabilized!) and a rated current of 1.25 A at this voltage.
I brought the power-unit to my lab for a test. When I measured the voltage without any load (no scanner connected) it read 12 V as stated,- so it seemed to be ok. But when I connected a load (a car light bulb 12 V / 3 W - equivalent to a current of just 0.25 A), the lamp just barely glowed and the voltage (that should be 12 V constantly) dropped to just 4 V.
This proved without any doubt that the power-unit was defect. It could no longer maintain a constant 12 V during load.
I had a variable power-supply in my lab that could be set to 12 V and connected to the scanner for a test. But Canon had made a very peculiar connection to the scanner by using a rare male power plug (with a center (+) pin inside). Normally a round hollow (female) plug is used on such power-units. So I cut the DC cable a few centimeters from the power-unit, split the two leads 4 cm apart and dismantled 1 cm of insulation from each end. On my power-unit one of the leads were marked all the way with text, and this one proved to be the minus (-) lead connected to the outer (metal) part of the DC plug. The two ends were connected to my power-supply (with correct polarity!), and the other end with the DC plug were connected to the scanner. Power-supply was switched on and my computer system was restarted. I opened the Paint Shop Pro program, clicked 'Twain Acquire' and the ScanGear CS window appeared. After this insident a calibration of the scanner is required: Close the lid with no document inside, click 'Advanced Mode >>' down right and then 'Settings' / 'Quality' / 'Calibration'. The scanner will do some adjustments for a few seconds and finish when the small calibration window close.
At last my CanoScan 5000F came back to life again. The preview was normal, and the scanned images as superb as they had been before.
Conclusion: Do not throw your scanner away! Buy a new power-unit with DC 12 V stabilized and at least 1.25 A. Brand is not important as long as it is of good quality and correct voltage/current, but cut and use the cable and plug from the defect power-unit as I described earlier. Remember to isolate the connecting area (+ and -) firmly.

Sometimes using technical jargon makes it harder for people to understand each other (this applies to both askers and answerers).
I always advise askers to use normal language as much as possible and answerers to do the same and where jargon is unavoidable, to explain as they go along.
Please post again to clarify what you mean by "..a duplex to pdf..", in normal language not in technical jargon.
A PDF is not a real, physical document. It is a digital document on a computer or a webpage created in PDF format.
A Duplex document is a real document, printed on both sides of each sheet of paper.
If you are trying to scan a multiple page Duplex Document using the Sheet Feeder of your scanner, the ink on the reverse side may be getting caught up in, affecting and/or staining one of the rollers in the Sheet Feeder.
The bottom roller in most non-industrial Scanner Sheet Feeders expects to touch only the plain reverse side of a sheet of paper as it is passed through and turned over to rest on the Platten (scanning surface) of the scanner ready to be scanned.
Multifunction printers with built in scanners and sheet feeders and duplex printing capability are designed in a way that makes them more forgiving of dealing with duplex printed paper.
Duplex printing printed in a laser printer is less likely to cause a problem as long as it is allowed to dry thoroughly. Inkjet printing that is allowed to drry thoroughly should also be okay.
If the scanning is being attempted very soon after printing, then the wetness of the printing may be the problem.
Sheet Feeders that handle duplex printed sheets invariably become stained and need periodic cleaning.
If the document is not too long, you may have to scan it manually, page-by-page.
If the document exists as a PDF somewhere on your computer or on the internet, then it is unclear why you would need to scan it. This is why your question is puzzling.
Post a further comment, if this answer does not help you solve the problem.
after reading the manual, http://www.lexmark.com/publications/pdfs/2007/2400/ug_en.pdf, yes it is possible - not that it tells you how to do it though so read on. Until you become familiar with the process just use one sheet of paper at a time in the printer. As you know, in the scanner the top right of your document goes to the right hand front corner of the scan bed (the clear window), place the page on the scanner and scan. Pick up the printed sheet of paper and flip it so the left hand side edge is now in your right hand and the right hand edge is now in your left hand and you are now looking at the blank side of the paper. Insert the page back into the sheetfeeder. Flip the page to copy in the scanner so the rearmost edge of the paper is now to the front of the scan bed and the front edge of the paper is now towards the rear (you should now be looking at the page you scanned previously). Scan the page. you should have now scanned both sides of one sheet of paper to another sheet of paper. as your printer does not have a sheet feeder for the scanner you have to do the process manually. hope this helps.
Most all-in-ones require you to scan an alignment sheet after changing the ink. Make sure the printer is on. Press Menu then use the up and down arrows to navigate to Maintenance. Click OK. Navigate to Auto Head Align and press OK. Select Yes and press OK. Load a sheet of Letter or A4 sized plain white paper in the rear tray, follow the on-screen directions. Open the output tray gently and the output tray extension. Press OK. When the page prints out, do not touch the printed sections. You should see a set of broken lines on the page, among other printing. The first section of columns will have 2 black, 1 blue and 3 black. The next row has 4 columns (blue and pink (to my eye)); the final row is 3 blue and 3 pink. If this prints okay, then select Yes and press OK. Next place the printed page face down on the glass of the scanner unit so that the black triangle at the top left of the page is in the left back corner of the glass. (The triangle is an alignment mark and lines up with the alignment mark on the edge of the scanner unit.) Close the document cover and press OK. The sheet will be scanned and the print heads will be adjusted. Do not open the document cover or move the sheet until the unit has completed the adjustment. Afterwards you can discard the sheet.
If the unit fails to adjust the print head, it will indicate this in the LCD screen. In that case, try manually adjusting the print head from the Canon Toolbox on your computer. If you can't get the printhead to align properly manually, the unit may need service.
This error message means ADF front side scanning optical alarm (lower optical unit ADF) which indicates ADF (front) lamp intensity check. Please follow the steps provided below:
1. Is the upper glass (white sheet guide)of the reading section dirty?
Open the ADF, and clean the sheet guide (white part) and the glass. # When operating the scanner, the ADF’s inside glass becomes very hot. Take serious caution as the heat can cause burns. Before you clean the inside of the scanner, turn off its power and unplug the AC adapter from the outlet and wait (at least three minutes) until it gets cold.Be careful not to pinch your fingers when the ADF cover is being closed. Note: Cleaning should be done approximately every 10,000 sheets scanned, though it may vary depending on types of documents scanned. More frequent cleaning is necessary when the following types of documents are scanned: - Smooth surface document such as coated paper - Documents printed on almost entire surface - Documents processed with chemical materials such as carbonless paper - Paper with a high calcium content - Pages with pencil lead - Document where toner is not fused sufficiently.
If the above does not help, then the issue is caused by any of the followings for which you may have to contact the Fujitsu Expert/Engineer.
1. Lower Optical unit ADF may be dirty. 2. Lower lamp may not be functioning properly. 3. The connecting cables might be damaged. 4. The connectors are not connected properly.
Put the pages in the "multiscan" all at once, not just one sheet at a time. The Automatic Document Feeder (ADF) will feed one sheet of your document at a time untill all of the pages are scanned...
Thanks for using FixYa!
Hello, you can print a calibration sheet from the front panel of the printer. Hit menu on the panel of the printer and scroll down to calibration printer and hit ok. Then hit ok on print calibration page and it should proceed to print a calibration page. After it is done printing, it will tell you to scan the calibration sheet.
