Copies are blank. The original is not set correctly. When using the exposure glass, face the originals down. When using the ADF, face them up. A moir? pattern is produced on copies. Your original has a dot pattern image or many lines. Place the original on the exposure glass at a slight angle. Black spots appear on the copy of a photographic print. Because of high humidity, the photographic print has stuck to the exposure glass. Place the print on the exposure glass in either of the following ways:

• Place an OHP transparency on the exposure glass, and then place the print on the OHP transparency.
• Place the print on the exposure glass, and then place two or three sheets of white paper on it. Leave the ADF open when copying.

White stripes appear on the OHP. Fragments of paper are stuck to the OHP. Use a dry cloth to wipe any paper fragments off the back of the OHP. The image on the back side of duplex copies has mottled blank patches or is smudged. Missing patches and smudges are caused by moisture leaking from the paper.

• Do not install the machine in areas that are susceptible to low temperatures.
• Use paper that has been stored where temperature and humidity conditions meet the limitations we recommend. For details about the paper storage conditions we recommend, see "Paper Storage", About This Machine .
• Install the Optional anti-humidity heater. For details about the anti-humidity heater, contact your service representative.

Adjusting the Scan Contrast or the Image Quality (Fax Resolution)
Adjusting the Scan Contrast

Contrast is the degree of difference between light and dark. Increasing the scan contrast setting further blackens dark areas and whitens bright areas, whereas decreasing the contrast setting reduces the difference between bright and dark areas. You can adjust the contrast among three contrast levels.

1. Press the button.
   
   

2. Press the button.
   
   

3. Press the (left) or (right) button to select the contrast.

Try
Clean the Scanning Area Cleaning the Platen Glass and Document Cover Caution
Be sure to turn off the power and disconnect the power cord before cleaning the machine.

Important

The inner side of the Document Cover (white sheet) (C) is easily damaged, so wipe it gently.

If the glass of the ADF (A) is stained with ink, correction fluid, or the like, black streaks may appear on the printed paper when the document is loaded in the ADF. With a clean, soft, lint-free cloth, wipe the glass of the ADF.

With a clean, soft, lint-free cloth, wipe the Platen Glass (D), the inner side of the Document Cover (white sheet) (C), the glass of the ADF (A), and the inner side of the ADF (white area) (B) gently. Make sure not to leave any residue, especially on the Platen Glass.


Cleaning the ADF Caution
Be sure to turn off the power and disconnect the power cord before cleaning the machine.

1. Open the Document Tray.


2. Open the Feeder Cover.


3. With a soft, clean, lint-free and dry cloth, wipe off any paper dust from the inside of the Feeder Cover (A).


4. After wiping, close the Feeder Cover by pushing it until it clicks into place.

5. Close the Document Tray.

6. Reconnect the power cord then turn on the machine.

The thick line is either because of dust sticking to the glass or a module problem. Try different brightness settings and scan white paper. If the thickness varies and also the sides of the black strip are jaggered (step like) then it is dust on Glass. use isopropyl alcohol to clean, dont use solvents. If the teickness is same for all levels of brightness and has a sharp edge always, it could be scan module problem.

Check your brightness setting for backside. Ideally keep it automatic, else you can manually choose the right brightness.

happened to me after i fed a page with not-too-hard whiteout on it. the feeder makes the page run through a different piece of glass and i just had to clean it.

Look at the narrow glass and see if there's white out or anything on it, also the white reference guide above the glass needs to be clean as well. The skinny glass under the adf is where documents are scanned when not placed on the big glass.

the problem is in the scanner, open it up and see if you can find any smudges, and clean any obstruction, any ink, liquid eraser residuals, can cause this part to appear as lines on your copied faxed image.
dont concentrate on the printer this is a scanner problem

There is a spot on the thin strip of glass that sits next to the large scanner glass. Because you are moving the paper when using the feeder, a spot appears as a line. Shining a flashlight on the glass can help you locate it. You can scrape it off with a finger nail or clean it with a damp cloth.
