Yellow edges down sides of paper

Probably it's the jammed paper that might caused the error. I suggest have it serviced by the technician. Be aware of the paper handling capacity of your machine to minimize jamming:

3300MFPV_X
Phaser 3300MFPV/X, Copy/Print/Colour Scan/Fax, B&W, 28 ppm, A4, 1200 dpi, 50-sheet ADF, 250-sheet Paper Tray, 50-sheet Multipurpose tray, 150-sheet Output Tray, 96 MB, Automatic 2-sided printing, USB/Ethernet, PCL/PS3, Scanning software, 220 V

Chances are high that the process of clearing the jam has resulted in ink being released from the cleaning/resting pad area based over on the right hand side (where the printhead sits when not in use).
This waste ink has probable come into contact with the rollers and other parts over on the right edge of the paper.
You'll probably see this ink slowly fade out and disappear over time. If it doesn't however there's something effectively feeding things so check the resting pad for a loose tube, overflow, puddles, etc...
If there's anything like that, report back (preferably with images).

after reading the manual, http://www.lexmark.com/publications/pdfs/2007/2400/ug_en.pdf, yes it is possible - not that it tells you how to do it though so read on.
Until you become familiar with the process just use one sheet of paper at a time in the printer.
As you know, in the scanner the top right of your document goes to the right hand front corner of the scan bed (the clear window), place the page on the scanner and scan.
Pick up the printed sheet of paper and flip it so the left hand side edge is now in your right hand and the right hand edge is now in your left hand and you are now looking at the blank side of the paper.
Insert the page back into the sheetfeeder.
Flip the page to copy in the scanner so the rearmost edge of the paper is now to the front of the scan bed and the front edge of the paper is now towards the rear (you should now be looking at the page you scanned previously).
Scan the page.
you should have now scanned both sides of one sheet of paper to another sheet of paper.
as your printer does not have a sheet feeder for the scanner you have to do the process manually. hope this helps.

Follow these steps to reload paper:

1. Remove the paper and make sure it's not curled or wrinkled.
   
   
2. Fan the stack to make sure the sheets are separated.
   
   
3. Open the paper support and pull up the extension.
   
   
4. Extend the output tray.
   
   
   
   
5. Flip the feeder guard forward. Squeeze the edge guide and slide it left.
   
   
   
   
6. Insert paper, printable side up and short edge first, against the right side and beneath the tab.
   
   
   
   You can load up to 100 sheets of 20 lb plain paper or up to 20 sheets of photo paper.
   
   
7. Slide the edge guide to the edge of the paper, but not too tightly.
   
   
   
   Follow these guidelines when loading paper:
   
   
   • Do not load paper above the arrow on the edge guide.
     
     
   • If multiple pages feed at once, remove the paper from the sheet feeder, fan the edges to separate the sheets, then reload it.
     
     
   • If you're printing on both sides of the paper, try loading fewer sheets.
     
     
   • If it's wrinkled when it ejects, the paper may be damp or too thin.
     
     
   • Do not load paper with holes punched in it for insertion in a binder.
     
     
   • Load the printable side face-up. It's often brighter or whiter than the other side.
     
     
   • Load letterhead or preprinted paper top edge first.
     
     
   • If you experience paper feeding problems, try loading fewer sheets.
     
     
   • If you're using special paper, check the package for special loading instructions.

Follow these steps to reload paper in the Automatic Document Feeder:

1. Remove the paper and make sure it's not curled or wrinkled.
   
   
2. Tap the originals on a flat surface to even the edges.
   
   
3. Move the edge guides outward.
   
   
   
   
4. Insert the originals face-up. You can load up to 30 letter-size sheets at a time. If you load legal-size sheets, insert only 10 sheets at a time. Make sure the originals are not creased or folded and do not have tape, staples, or other materials that could obstruct the feeder.
   
   
   
   
5. Slide the edge guides against the originals.
   
   

Hi there,

Loading Paper into your Canon MP 160 Pixma.

A) Loading Paper :
Follow this procedure:
1) Open the Paper Support, then pull out the Paper Support Extension.

2) Place a stack of paper (print side up) in the Auto Sheet Feeder, pinch the Paper Guide and adjust it to the left side of the stack.
* Set the Paper ThicknessLever to the correct position for the paper.
Note : Set the Lever to the left for most paper. When the Lever is set to the right, the confirmation message appears before the machine starts printing.
Important : Make sure the stack does not exceed the Load Limit Mark.


B) Loading Envelopes
Follow the following steps:
1) Open the Paper Support, then pull out the Paper Support Extension.

2) Prepare the envelopes for loading.
Important : * Press down firmly on the edges of the envelopes to make the folds crisp. Also, press firmly on the area that corresponds to the edges of the back flap.
* Remove any curling by holding the edges diagonally and bending them gently.
* If the edges of the envelopes are inflated or curled, place the envelope on a flat surface. With a pen, press down while moving it from the center toward the edges of the envelope.
* Ensure that no curl or puff exceeds 1/8 in. (3mm).

3) Place the stack of envelopes (print side up) in the Auto Sheet Feeder, pinch the Paper Guide and adjust it to the left side of the stack.
* Load the envelopes in the Auto Sheet Feeder with the short side down.
* Set the Paper Thickness Lever to the right.

Important : Make sure that the stack does not exceed the Load Limit Mark.

Hope this helps. PLease rate my response.
Thanks
Have a good day.

Open the printer cover and look closely for tiny paper shreds that might got stuck between the rollers. If you have a canned air, try blowing out the paper path as those tiny piece of paper might be blocking the paper sensor.

Try this 1.Try placing sheet of paper on copy board, and run many copies . I ran 25x12 times - still blanks coming out. Run head clean after about each 50 sheets. Persevere

Clean the rollers down where the paper sets in the printer. Do not use cheap generic matte coated paper. Some generic matte coated paper will leave a film on your rollers and cause them to not grip the paper.

dear sir please check the upper heat roller claws set,may be one of them is bended up

I don't really want to get into this, but you sound desparate. i don't work on your model very often, so bear with me. When a sheet jams, don't just pull it out. Open the document feeder as far as you can and note where it stopped (the side tha DID NOT feed). Look for a possible obstruction or even spot of something that looks dirty or sticky. If so, remove or clean it. Look at the leading edge of the jammed sheet, see if there are any indentations that could possibly line up with a sensor flag, roller edge, etc. Last suggestion. Press down of the side of the document feeder that DID NOT feed through. If this helps, then there is a problem with the latch that holds the document feeder closed. Without seeing the unit it is difficult to diagnose correctly. Let me know one way or the other. Any observations will be helpful. Ed One more thing! Make sure the leading edges of the pages you are sending are perfectly straight and smooth. Make sure that they HAVE NOT been stapled at one time (the indentation can cause a problem)
