Cleaning the encoder strip (Loud bang from printer carriage)

Check this out for the error. The trick here is to make sure the bar is cleaned and lubricated with furniture polish or cooking oil.

1. The cartridge may be dried up.
2. The cartridge contacts in the printer may be damaged.
3. Mechanical interference prevents print heads from moving.

If your cartridges are rather new but have not been used recently (a few weeks or so), they may be dried up. You can test this by removing one cartridge and applying rubbing alcohol to the nozzles. Let it sit this way for a few seconds and put it back into the printer. If your test page shows some streaks instead of nothing, that is your problem.

Open the printer cover. If the print cartridges move to the correct location for replacement, there is not mechanical interference. If the motors make noise but the cartridges do not move, there may be an obstruction in the printer. Try to clear it.

If neither of these are the case, try replacing the cartridges with genuine Lexmark cartridges certified for your printer. If this does not remedy the situation, your printer's contacts or other components are damaged. In this case replace the printer.

Hi there, just found this solution to work perfectly. i just freaked out for a moment with the same problem. Use this or just type fax and scan in your help function. Hope this helps!

Before you begin, make sure that you've installed your scanner on the computer and that the scanner is turned on.

1. Windows Photo Gallery.
   
2. Click File, and then click Import from Camera or Scanner.
   
3. In the Import Pictures and Videos window, click the scanner that you want to use, and then click Import.
   
4. In the New Scan dialog box, click the Profile list, and then click Photo. The default settings for scanning a picture are automatically displayed.
   
5. If you're using a scanner with a document feeder, click the Paper size list, and then click the size of the picture that you've placed on the scanner or click the size that most closely matches the picture.
   
6. Click the Color format list, and then click the color format that you want the scanned file to display.
   
7. Click the File type list, and then click the file type that you want to use to save the scanned file.
   
8. Click the Resolution (DPI) list, and then click the resolution, in dots per inch, that you want to use.
   
9. Adjust the brightness and contrast settings or type the values that you want to use.
   
10. To see how the picture will appear when it is scanned, click Preview. If needed, modify the scan settings, and then preview the picture again. Repeat these steps until you're satisfied with the preview results. Some scanners might require you to place the picture in the document feeder each time that you scan.
    
11. Click Scan. When the scan is complete, Windows Photo Gallery prompts you to tag the picture so that it's easier to organize or find later.
    
12. In the Tag these pictures (optional) list, type a tag name, and then click Import. Windows Photo Gallery displays the picture so you can view, fix, or organize it.
