Skewed paper feeding

- SG-101

- Paper feeding from the

ASF

- 10 sheets (max.) set in

the ASF

Since the sub-rollers usually do not contact the paper, ink mist can easily accumulate, especially during printing on small- sized paper which never contacts the sub-rollers.

When 10 sheets of paper are set in the ASF, and if they warp significantly, the warping portions of paper get over the cover guide, not being aligned along the guide properly.

-Straighten the paper.

-Set 5 or less sheets of paper in the ASF.

- Paper feeds at

an angle.

- A margin

appears on

printouts.

Due to decrease of the friction coefficient and inaccurate print head alignment.

When printing on paper is done with the inner cover open, the print immediately after ink is ejected on paper is scratched by the bottom of the inner cover, resulting in smeared print.

When a glossy photo is strongly pressed on the platen glass, the photo will stick to the glass, and the stuck points are scanned as spots.

For photos in general, both the thumbnail and the original image are in landscape.

However, when original images are in portrait while thumbnails are in landscape, the trimming frame shifts from the correct position in some instances.

Due to a bug in MP Navigator 2.0.

Since the automatic cropping process is incorrect, improper correction of skewed scanning is done depending on a document, resulting in the skewed scanning.

-Perform Manual print head alignment.

-Perform Bottom plate cleaning.

Close the inner cover completely.

-Do not strongly press the photo on the platen glass.

-Clean the platen glass (to eliminate any moisture).

The phenomenon is left as is.

-An information sheet regarding the phenomenon is packed with the machine in early production.

-MP Navigator will be upgraded on a running-change basis.

-If the phenomenon occurs, cancel "auto detect" and select the paper

- Uneven printing

the paper.

- Printing gets

- Spots appear on

the scanned

image, though

there is no such

spots on the

original

document.

- Print result

what is

displayed on

the LCD.

-An image is scanned at an angle.

-Some portions of an image is not scanned.
