    i have tried that, the marks seem to inside the unit under the scanning area. it looks almost like condesation, but its got a red sheen to it. i brought the printer a year or so ago but have never need to use the scanner untill now. every thing else is fine with the unit apart from these marks. cannon are not intreasted due to it being out of warrenty by a couple of months.

    The smudges are on the INSIDE of the glass... It has to be opened to clean it, because there's no way to get to them otherwise...

How to clean the glass underside of the hp scanjet g3010

working with computers since 1964 (yes, there were computers even then...), with consumer scanners since 1988, servicing hp equipment and scanners since 1998, for saving my life - i never, ever see any smudging on internal surface of the glass... could you kindly elaborate how you get smudging there?

there is no consumer serviceable parts inside, these are "disposable" scanners and never intended to be repaired or serviced inside.

Incomplete text, every other line is messed up.

  • If the scanner glass or the white scan background (the white portion of the lid) are dirty, the scan might be different than intended. A dirty scanner glass (fingerprints or smudges) slows down performance by as much as half a minute and affects scan quality. Performance slows because the product is actually processing the smudges on the glass. Turn off the product , and then clean the glass with a soft cloth or sponge slightly moistened with a nonabrasive glass cleaner. If there are visible contaminants under the scanner glass, the product must be sent in for servicing. You cannot remove the scanner glass to clean inside.
  • Reinitialize the scanner by turning off the product and unplugging the power cord. Make sure that all original documents are removed from the product and that the scanner glass on the product is clean. When the power is reconnected and the product is turned on, the scanner recalibrates.
  • The computer video driver and video settings might change the image appearance slightly. The product scans in 24-bit color. Setting the video display settings to less than 24-bit, or 24 million colors, results in a loss of color information on the computer monitor. The video driver might change the appearance of colors when viewed on the monitor.

    How do I clean the INSIDE glass/platen?

    You mean the inside of the scanner glass? (The platten is a part of the print unit),

    You'll have to remove the sides and read cover. Unplug the scanner wires and remove the scanner assembly. Separate the document feeder from the scanner bed. Open the covers of the scanner bed (usually there are screws holding it together). Remove the glass and clean it. Reverse the process to reassemble.

    Be careful. Canon multipasses are built a little like a Chinese puzzle box. There are little snaps everywhere as well as screws. Watch out you don't force anything and cause the snaps to break.

    The problem is not your scanner, is in the rollers, the rollers are smudged with ink or other mateial or your glass is smudge, remove the four star bolts on the top and clean the undersurface of the glas with a conventional glass cleaner wipe and re install the top cover.Be careful with the ribbon cables connected to the circuit board.
