Canon P-150M manual 93

Problem 5 Documents fed askew are causing scanned images

	to be slanted.
Solutions	(1)	Align the document guides to fit the documents as
		closely as possible, and place the documents so
		that they feed in straight.
	(2)	Enable [Deskew] in the settings of the scanner
		driver.
	(3)	If many pages have been scanned since the last
		roller cleaning, clean the rollers and separation pad.
		If documents still feed askew, roller replacement or
		other maintenance may be needed. (See p. 87.)
	(4)	Perfectly straight scanning may not be possible for
		the document due to the structural design of the
		scanner.

Problem 6 Two-sided scanning is set in the scanner driver but

	both sides are not scanned.
Solutions	Note that if you use a job for which scanning only one
	side is set in CaptureOnTouch, only one side will always
	be scanned regardless of the settings of the scanner
	driver. For example, if you set one-sided scanning on
	the [Scanner setting] tab of the [Job Registration] dialog
	box of CaptureOnTouch, one side will always only be
	scanned with that job. Change the setting of the job or
	create a job for scanning both sides.

Problem 7 White lines/streaks appear in the scanned image.

Solutions	Clean the scanning glass (both the top and bottom) and
	rollers. When cleaning off dirt with adhesive properties
	such as glue and correction fluid, try applying a little
	pressure when wiping the places corresponding to
	where the lines appear. If the problem is not solved after
	cleaning, the inside of the glass may be scratched.
	Contact your local authorized Canon dealer or service
	representative.

Problem 8 Pages are skipped (missing).

Solutions	If [Scanning Side] of the scanner driver is set to [Skip
	Blank Page], pages with few black portions may be
	unintentionally deleted (skipped). Select another
	scanning mode such as simplex or duplex, or reduce the
	ratio for black dots. For the solution for missing pages
	caused by double feeding, see the following “Problem 9
	Pages become jammed or double fed.”
Problem 9 Pages become jammed or double fed.
Solutions	(1) Scanning cannot be performed properly if the pages
	of the document are sticking together because of,
	for example, static electricity. Before you load a

document, thoroughly fan the pages.

(2) Reduce the number of pages that you load into the scanner at one time.

Problem 10 I want to save scanned images in JPEG format, but they are saved in TIFF format.

Solutions	If a document is scanned when [Mode] is set to [Auto
	Color Detection] in the settings of the scanner driver,
	documents detected as black and white are
	automatically saved in the TIFF format regardless of the
	setting. This is because the JPEG format does not
	support black and white binary images. If you want to
	save all scanned images in JPEG format, set [Mode] to
	[Color] or [256-level Gray] and then perform scanning.

Problem 11 The scanned images are saved separately as multiple documents.

Solutions	When output file format is set to TIFF or PDF in
	CaptureOnTouch, multiple pages can be saved as one
	scanned image. To achieve this, select [File type], and
	then click the [Advanced Settings] button and select
	[Save all pages as one file] in the dialog box that
	appears.
