aficio 1045-problem in copy mode

[tcs04]

ehhhhhhh! NOT wrong!!!!!!!!!!!

See attached. (Raised for paralleogram image, bur caused the PCQ problem due to the ADF not being close enough to the slit glass)

".......... An excessive load has been applied to the Scanner Stand, cauising it to bend"

Hence the increased thickness of the modified Guide Plate (item 27) and the extra Support Bracket to prevent the Guide Plate bending at the mounting point (Force x Distance... Isaac Newton was correct!)

i make copy from both glass and adf on A4 but the problem is the same dark copy with white lines against the direction of paper,but if i tried to
print total counter copy is great-its ok,i planning to change ccd,what do you think?

This sounds like a problem with Auto exposure. The machine checks a stripe about 1" wide near the rear edge of the glass. If the intensity varies as the scanner moves across the image density will vary right across the copy as you seem to describe. Try taking a copy using manual image density.

Is the lamp flickering as the scanner moves?

Is the scanner movement smooth?

Is there any blurr on the copy?

Are all the mirrors properly located?

Is the image square?

Is the sub scan magnification correct ("Feed" direction)?

Do the bands appear at a uniform spacing along a copy?

Have you removed the left scale and cleaned the white level plate?
