Black streaks Copies have 7 evenly spaced horizontal black streaks on them. Platen glass and cover are clean. Cleaning instructions in Basic Guide pg 7-2 are for D340 only. How do I get to what needs cleaning?

Hello,
when you open the copier platen cover, left of the copy glass, there is small narrow glass, which is used when you make copies from ADF. Over that glass is plastic protective sheet. Remove it and clean, also clean the glass. Use glass detergent and after cleaning dry it!

Even the smallest dirt can cause lines!

Hope that helps!

1. Lift the document cover to expose the platen glass.
   
   
2. Wipe the platen glass (A), white areas (B), and transparent sheet (C) with a clean, soft, lint-free cloth moistened with water. The MP700 has one even platen glass and does not have an area like the one referenced in area (C).
   
   
   
3. Then wipe with a clean, soft, dry, lint-free cloth making sure there are no residues left, especially on the platen glass.
   
   
4. Close the document cover and make a copy of a text document to confirm the black line has disappeared.

Documents scanned/copied from the document feeder pass over a thin glass area where scanning occurs. Clean this area if sent faxes, copies or scans have black or white vertical lines.

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.

open the document lid. Check to see if there is white-out on the glass platen where the document rides across the scanner. Some units require the white roll to be taken off.
sometimes a black mark on this platen can leave black streaks on copies made on this machine, and even when they send to others.
Try to clean the platen glass.

Try to print something, if there is any streaks?If no the problem is in copy glass (dadf or platen glass).

If there is streaks on print also,it could be the drum unit ( pull the drum unit out and see if on drum surface is any black streaks), fixing film is worn out, and in the worst case you have problem with toner unit ( on toner unit you have current leackage ) and you need (in best case) clean the contacts on toner unit, and in more expencive case tochange the toner unit.

Does it do it on prints aswell as copies?

If so open up the Left hand side door if you peer inside at the fuser (hot bit) can you see any damage. if so needs replacement.

Also could be the drum, look in the same area at the green/blue cylinder, these do up to approx 30,000 pages.

Hope this helps.

the document feeder of that unit have its own scanner glass. try opening the document feeder and clean the scanner glass with a lint free cloth that is moist with water and also clean the rollers of the document feeder

hello,first of all,make a copy true the adf,and the next on the platen glass,if both copys are good,then the problem is inside the machine,i.e.drum unit or fuser roller damage.
if the strikes only occurs,by using the adf,then cleaning the scanner platen glass,it is the small glass unit!!! on the left side,from the big platen glass..

good luck Sjeuf

Good, so u are having probs in ADF. Open the cover, lift the rollers and u can see the scanning glass. Take a lint free cloth and clean it. it will be ok.
