Dirty print out is basically due to cartridge related issues. Take out the cartridge and clean its drum/ (green roller) with a dry, soft, lint-free cloth. The drum is usually located under a cover. Checkout for any spilled toner inside the printer and clean it also. Print a few pages so that the parts get further cleaned. I think, this would solve the issue. (This may help temporarily)

Moreover, streaks (thicker lines) and dots etc indicate faulty PCR Roller which is located behind the green drum inside the cartridge.
So, it is recommended that you replace the cartridge with a genuine one (not any replacement or refill).

Let me know if any further clarification is required.
Hope it helps! Good Luck!

Ink is printing streaky, but this is my second brand new ink cartridge. Any suggestions?


this symptom signals blocked printhead, you need to do bit of cleaning, not necessarily cahnge the cartridge.

follow this procedure:
1. download test page with alternative from this site black:
http://www.inkjetcartridges.com/_black-print-test.html

and colour:
http://www.inkjetcartridges.com/_color-print-test.html

2. print page each and assess the colour and streaks. if on the beginnig of the page you do have errors and on the bottom all is corrected, this meant that you just cleaned your printhead nozzles and problem is solved.
3, if problem persist, from stationery store purchase few pages of absorbent paper, weight of about 120 to 160, do not use thicker than 160 and print these colour pages again,
4. print control page again and see if any improvement was made, if there were no changes, follow this procedure:

a. remove cartridges from craddle
b. determine what is ink solvent, water, isopropyl alcohol or methylated alcohol - correct solvent will be that which do not precipitate or curdle the ink
c. touch with absorbent tissuebottom of the cartridge and check if it is leaving even print, if not, whipe once with solvent
d. put a drop of solvent on gold/silver buttons inside of the craddle, allow to sink for about a minute, whipe off with absorbent tissue
e. put again a drop of solvent on the button in the craddle and insert ink cartridge
f. print test page, page will be very weak on the top (solvent print first!) and improve as it prints down, if necessary, print again colour or black test page from 1.

this should solve your streaking head problems, if they still persist, this meant that print heads are really well blocked by caked ink and usually is cheaper to change printer than change the head in it...

if you find this advice useful, please do not hesitate to leafe your feedback and vote for me, thanx!

Epson black print has color streaks in it and my color print has different different other color streaks in it. What is wrong? I have experienced this problem with a couple of different printers I own....


I have personally encountered similar problem in my work.
 
Sometimes when either of the inks overflow at the nozzle, it gets absorbed to an extent into another ink compartment. So that colour affected now prints another colour; the colour that has crept into its compartment, Sometimes it is serious at other times is not. If not serious, usually, after a few solid colour prints the colour affected returns to normal.
 
I do not know how much of a technical person you are, but I will give you the solution to returning that colour to print rightly. Bring out your colour cartridge. Peel off the seal covering top. You will see the holes through which in is fed into it. Get a clean handkerchief, fold it and place over the top of the cartridge. Hold it over a bowl or something. Now place your mouth over the top with the handkerchief in between and blow hard. Ink will discharged at the nozzle. Clean off the ink with folded tissue; always dab not wipe. (At the nozzle do not rub only dab). Now press a piece of folded tissue to the nozzle firmly. It should be blotted with ink:- red, blue, yellow. If any colour is missing you may need to repeat the procedure. Once you get the three colours back, the issue is resolved.

Faded-out streak


check your ink levels. if its the ink that came with the printer it is probable running out of ink. they do not give a full cartridge with printers, only about 3rd full. also try cleaning the heads. and try changing your printer settings/prefrences to less ink, more drytime see if that helps.

When I print photos, they have uniform vertical streaks.


Issue: Banded or streaked prints
Solution: Change the Print Quality Settings (Windows)

Change the Print Quality Settings (Windows) The Quality setting controls how finely ink droplets are placed on the printed page. Depending on the type of paper being used a higher Print Quality setting does not always insure a better print. Print speed will decrease as the Print Quality setting is increased. Follow the instructions below to change the print quality settings in the Canon printer driver for the Windows operating system through a printing application.
  1. Click 'Properties' in the Print dialog box.

    Note: Depending on the Application software, 'Properties' may be displayed as 'Preferences'.

  2. Set the desired print quality in the 'Print Quality' section.

  3. Select 'High', 'Standard', or 'Draft / Fast'.
To set more detailed print quality settings, follow this procedure:
  1. Select 'Custom' and click 'Set'.

  2. In the Set Print Quality dialog drag the slide bar from 'Fast' to 'Fine' to select the print quality.

    win_print_quality_slider.jpg

    Note: There are five options in 'Quality'. However, selectable options are limited depending on the media type.

  3. Select 'Auto', 'Dither', or 'Diffusion' from the 'Halftoning' section.

How to print envelopes on my printer


Use The Recommended Print Area For the best printing results, adjust the top and bottom margins of your document to within the recommended printing area shown below. Click on the paper size listed for the recommended print area settings: A4 / B5 / A5 / 4 x 6 / 4 x 8 / 5 x 7 / Credit Card, Letter and Legal, Envelopes (DL / COM#10)
Caution: When printing is performed outside the recommended printing area, the top and bottom edges of the paper may curl, the print quality may deteriorate, or the printed side may be smudged.
The printer has both the recommended print area and the printable area, according to the paper size.
05sj00144_01.jpg Recommended print area: This indicates the recommended print area.
05sj00144_02.jpg Printable area: Although this indicates the printable area, degradation of print quality may occur.
Note:
  • Set Borderless Printing to print without margins.
  • In Duplex Printing, the printable area of the paper's header is approximately 2 mm narrower than usual.

Red streak poor color


If streaking is occurring only at the bottom of the page (i.e. the last area to print as the paper is fed beneath the print head), the problem may be due to improper curl of the paper. Many inkjet printers (Canon especially), rely on a slight curl of the paper so that it is "bowed" when it travels beneath the print head.

To see if this is the problem, gently roll a sheet of paper so that the print side is on the outside of the roll. When you place the paper in the feed area, it should have a very slight bow so that the center of the print side is slightly raised off the surface, while the edges are on the surface.

Also, make sure you use only OEM (Canon) cartridges. There is not a single "compatible" cartridge in the world that won't screw up your Canon print head. Take my word for it (and I DON'T work for Canon), you must use only Canon cartridges.

DELL 3000cn Printing Problems


switch off the printer then switch on again whilst holding the UP and DOWN menu scroll buttons simultaneously.

Then you can go to a TEST PRINT area and print off pages of idividual colour.

If the streaks appear on ALL prints its likely to be the laser unit. If the streaks only print on the COLOUR sheets ( not BLACK) then the problem lies with the drum or the transfer belt.

Remove the drum and turn it manually with the gog at the side and give it a clean with a soft LINT FREE cloth, do the same for the transfer belt and then you may have to run a few test prints to get it all reprimed but you should be OK.
