Scanned result is cockeyed

Sometimes, not always, the scanned result is cockeyed. The document or picture to be scanned is in perfect alignment with the edge the scanner glass. After scanning the result can be off the vertical by as much as 15 degrees. Is there a solution to this periodic problem?

Hello Ismail,

Error U1 referes to Frequent paper jam in Fujitsu fi-5650c scanner. In order to troubleshoot your scanner issue, you are advised to follow the steps provided below:

2. Have the documents been prepared properly?

- Remove documents with creases or dog-ear corners.
- Scanning different widths documents may cause skew and result in paper jam.
3. Is the imprinter EXT cable connected to the scanner properly? (only when the imprinter is installed)
4. Clean the Pick roller, the Separation roller, the Brake roller and the Chute roller and see if the error is resolved.
5. Clean the Feed rollers and the Plastic rollers and see if the error is resolved.
6. Replace the Pick roller, the Brake roller and the Chute roller, and see if the error is resolved.

I have a Fujitsu 4220c2 scanner and when scanning multiple documents it'll take one half half/quarter way through and get stuck. The pick roller and pad assembly have been replaced. What could be causing...

Thank you for contacting Fixya.
This error is detected when one of the followings occurs: (TWAIN Error-Paper jammed in the ADF - Code DS32002), Scanner panel error-U1
1) A document does not reach the TOP sensor while the scanner has transported the document about 250 mm to pick. (The scanner performs retry operation.) 2) The trailing edge of a document does not reach the TOP sensor after the scanner transports the document by the length (L) below. (The document may have slipped on the rollers) Check the followings: 1.Scan condition - Transported length (L) before jam 2.ADF fixed size - scanning Approximately 450 mm 3.Long paper scanning -1.2 times of the specified value
If the imprinter is installed, paper jam can occur in the following case. If the scanner starts scanning when the imprinter cable (EXT cable) is not connected to the scanner, it does not rotate the imprinter, since it recognizes the imprinter not installed, which results in paper jam in the imprinter section.
Remove the jammed document and close the ADF. When the error frequently occurs, refer to the followings:
1. Do the documents satisfy paper specification? Please read the operator guide for paper specification. 2. Have the documents been jogged? • Align the edge of documents for stable paper feeding. • Remove documents with crease or dog-ear. • Scanning different width of documents may cause skew and result in paper jam. 3. Is the Imprinter EXT cable correctly connected to the scanner? Check the cables. (only when the Imprinter is installed) 4. Clean rollers in ADF and Imprinter and see if the error is removed. (only when the Imprinter is installed) 5. Replace Pick roller and Pad ASY and see if the error is removed. Check the consumable counter from the TWAIN driver screen. When the counter exceeds the values shown, replace Pick roller or Pad ASY.
If the above do not help, then the issue could be caused by the followings:
6. Malfunction of TOP sensor. 7. Malfunction of Cover open sensor. 8. Faulty Scanner Control PCA.
If Imprinter is installed, then the issue could be caused by the followings:
1. Malfunction of Sensor OPB5 lever (only when the Imprinter is installed). 2. Malfunction of Motor LF if the imprinter roller does not rotate.(only when the Imprinter is installed). 3. Faulty Imprinter Control PCA. (only when the Imprinter is installed).
Hope the above information is helpful.Please revert if you have any doubt.

You have two options for scanning text. You may explore both of them and see which is better for you. Either way, you will have to make friends with manually changing the scanning settings, because simple presets often are not suited for every case.

First is to use Grayscale mode, and a minimum resolution of 200dpi. This should give you satisfactory text quality. If you want to print the text afterwards, 300dpi would be even better. You may want to increase contrast, to get the letters more defined and eliminate most of the background toning.

Second is to use Black and White (monochrome) mode, but in this case you need to set the resolution higher, preferrably to 600dpi. Also in this case you will have to play with the Black/White threshold in order to eliminate background "dirt" appearing as black artefacts.

If you scan the documents in order to process them with OCR software, usually the OCR application will give you suggestions on how to set the scanning parameters to obtain good results.

Black line through the middle of the document

The thick line is either because of dust sticking to the glass or a module problem. Try different brightness settings and scan white paper. If the thickness varies and also the sides of the black strip are jaggered (step like) then it is dust on Glass. use isopropyl alcohol to clean, dont use solvents. If the teickness is same for all levels of brightness and has a sharp edge always, it could be scan module problem.

What brand of scanner is it?

Check in your Twain settings if you have auto-edge detection enabled. Sometimes this will mistake content on the page for the edge of the document.
