We have red and yellow ink at the edge of the right side of paper is there anything we can do about this?

Does the yellow tend to show heavy on one side, such as the at the edge of the paper?

Are you using Xerox ink? If not replace the ink and use Xerox ink.

This could also indicate that there is heavy build up within the printer head.

Try running internal cleaning function to see if that reduces or fixes the issue.

Let me know if that helps.

If it is pure yellow I would look at the yellow imaging unit (drum) to make sure that it is ok. That is likely the culprit if changing the toner did not resolve the problem.

Check for any small paper jam. Check the rollers, also use an alcohol swab to clean the rollers and check for ink leaking. Check you ink pad, it could be time for a new one.

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).

Inks from your printhead is deposited on right side of the soft sponge across the printhead pathway. Take a tissue paper and fold it and gently dap it dry

You need to clean your corona wires. Go to Brother support website. Look for Problem 100000012419 and follow steps in solution 200000015852.

A technique to improve print quality is to try and clean the cartridge nozzles. You may clean the cartridge by following the steps given below:
1. Go to the "Lexmark solution center." This can be done by clicking on "Start," go to "Programs" and Lexmark printer group. Click on the "Lexmark Solution center." Next click on the "Maintenance" Tab.
2. Select "Clean and Fix Horizontal streaks." Click on "Print". This will produce a printed page.
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.
If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzle" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:
1. Please open the "Solution center" again and go to the "Maintenance" Tab.
2. Select "Install color/black cartridge" and remove the cartridge or cartridges from the printer.
3. Get a damp paper towel.
4. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds.
5. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean.
6. Next dab the cartridge on the towel to make sure that the ink is flowing.
7. Snap the cartridges back into the printer.
8. On your computer, select "Old Cartridge install."
9. Repeat the "Clean Nozzle Page" one more time. If this fails to address the problem the entire procedure may need repeating.

The printer colour cartridges are magenta, cyan and yellow. The printer prints "red" by mixing magenta and yellow ink. So, if you only get yellow when you print red, it means you aren't getting any magenta ink on the paper.

Have you tried a cleaning cycle? If not, try one (right click the little printer icon in the bottom right corner of the screen and select head clean). Now run a nozzle check (right click the little printer icon in the bottom right corner of the screen and select nozzle check). Is there any sign of magenta ink on the paper. Try up to three cleaning cycles. If ink is now flowing, but not yet perfectly, don't carry out any more cleaning cycles. Just leave the printer for 24 hours (to allow any air in the print head to disperse). Then repeat the cleaning cycle/wait process. It may take a while to restore a perfect nozzle check print.

If you have already done lots of head cleans with no result, are you sure you have a good magenta ink cartridge? To eliminate the possibility of a faulty cartridge, buy a new set of compatibles on E-Bay - they're very cheap. You can always re-use the old one later if it turns out it is OK.

If none of the above works, then you may have blocked magenta print head nozzles. You can try soaking the print heads for 24 hours (or more), as follows. Turn the printer on, and as soon as the print head moves out of its parking position, pull the power cord out of the back, or turn the printer off at the mains. You may now carefully move the print head by hand over to the left hand side out of the way. Look inside the print head parking area on the right and you will see a small rubber cup that comes up to cover the print nozzles when the head is parked (to stop it drying out). Use a syringe or dropper to fill this cup with head cleaning fluid or distilled water. DO NOT USE TAP WATER. Carefully push the print head by hand fully into its parking position so that the cup full of fluid
comes up over the print head. Do not turn the printer on at any stage in this process. Leave this for at least 24 hours, then turn the printer on and try a head clean/nozzle check again. If you get any magenta ink on the nozzle check, then there is hope! Repeat the process until you get a full magenta nozzle check. If nothing, repeat the process once more.

If still nothing, post a new comment detailing what you have done and the results.

This is what worked (so far) with my Dell AIO A940 printer that wouldn't print black ink.

It worked for awhile when I chose photo/glossy paper, but then it quit printing again (see below).

PRINT, PROPERTIES, PAPER SETUP, SPECIALTY PAPER, PHOTO/GLOSSY


I got it to print, again, by putting SEVERAL papers in the feeder (instead of just 1) - there is a sensor that is supposed to automatically detect paper type, and it might not be working right, especially with one or only a couple of sheets.

Check your application's print settings (for e.g. MS Word). Then check the printer's properties and print settings. If nothing works you also try re-installing the latest printer driver. If you use MS word should check the page setup option, for paper size errrors. If the color of your margin is red and the red ink is out then you won't se the margin line.
