SLOW PRINTER

You have a cartridge problem.

This condition is typically caused by one of the cartridges failing. Try removing the black cartridge and printing (not copying) a test page. If this prints at near normal speed the black cartridge is at fault and should be replaced. If the printer still prints slowly then put the black cartridge back in and remove the color cartridge, then print a page. Replacing the cartridge that causes the slow printing with a fresh cartridge will resolve the issue.

Printer only prints in black/white. have put new

It could be the print setting on your computer.
If you're using Windows, with your document open, go to File > Properties/Preferences. In the Print Setup tab, make sure to select "Print using all available ink" in the Ink Use section.
On Mac you can select Color in Print Setting in any expanded print dialog.

I have installed new cartridges the colour prints perfect but the black is blurred with lies through it. i also found a small t shaped rubber piece about about 4mm x 6mm in the paper tray could this be the...

this rubber piece can be actually locket from printer rollers, but, returning to your smudgy printing

1. remove cartridges from the printer
2. check if there is bit of paper stuck anywhere in paper path, if so, remove
3. check if rollers on paper path are clean
4. touch bottom of the cartridge with absorbent tissue to check if ink is flowing through, if yes then insert cartridges back and print test page.
5. if cartridge do not allow inkflow, check what solvent is used (water, isopropyl alcohol or methylated spirit - this which do not cause precipitation is correct solvent), soak absorbent paper (tissue) with proper solvent and whipe head of the cartridge with it, 6. put drop of the solvent on golden knobs inside seats of the cartridges of the printer, allow it to soak in, wipe off with lint free tissue and put another drop of solvent in. allow soak in,
7. install cartridges back, print test page, it should start printing very weak and improving as it goes through the page (solvent will be printed first)
8. create "strip page" one line yellow, white space, one line cyan, white, magenta, white, black - print that page, this print will clean printheads and establish good inkflow.

all ink printers must print at least one page per week as to keep heads free of gum and ink in flow.

New ink cartridges. Printer won't print and does not show the new cartridges.

Step one: Run the clean print cartridges utility

1.
Press the Setup button.
2.
Press the down arrow key.
3.
Select Clean Print Cartridge and then press OK . The device prints a test page.
4.
Examine the test page. If the print quality of the page is good, stop here. If the print quality is bad, go on to the next step for further cleaning.
5.
Open the Printer Toolbox . There are two ways to do this:
*
select the Settings menu, then the Print Settings submenu, and finally the Printer Toolbox .
*
Open Printers and Faxes in the Windows Control Panel , then right-click your printer icon and choose Properties . Click Printing Preferences . Click the Features tab, then click the Printer Services button.
6.
The Printer Toolbox opens. On the Device Services tab, click Clean the Print Cartridges , then follow the on-screen instructions. Up to three levels of cleaning are available. Discard or recycle the page that prints.

Step two: Replace the problem cartridge (you probably have a defective cartridge)
If a cartridge replacement was not tried previously to solve this problem, replace the problem cartridge now

Cause and prevention
Color mix is usually caused by a material touching the nozzles. Ink can wick along the material and travel from nozzle to nozzle. When different colors of ink mix in this way, the result is muddy, inaccurate colors.
Missing colors occur when the cartridge nozzles dry out, or when a color is exhausted because of specific printing demands.

*
Do not remove the protective tape from a new print cartridge until just before you install it. Once you remove the tape, do not reapply it.
*
After you have removed the protective tape, do not allow anything to touch the nozzles.
*
Print at least once a month to keep the print cartridges in good working order.
*
Always turn the printer off by pressing the button on the printer control panel, rather than by unplugging the printer. Turning the printer off properly allows it to protect the cartridges.
*
If you are removing a cartridge from the printer temporarily (for instance, removing the black cartridge in order to install the photo cartridge), put it in a cartridge protector.
*
If you do not have a cartridge protector and need to remove a cartridge temporarily, put it in an airtight plastic tub. Make sure nothing touches the nozzles. Do not use a plastic bag. If you intend to store print cartridges in a tub for a long period of time, place color cartridges with the nozzles down, and black cartridges with the nozzles up.

I get an E 6 code in display

According to your owner manual from Canon, it says...

Ink has run out.
Replace the ink cartridge and close the Scanning Unit (Printer Cover).
If printing is in progress and you want to continue printing, press the Stop/Reset button for at least 5 seconds with the ink cartridge installed. Then printing can continue under the ink out condition.
The function for detecting the remaining ink level will be disabled.
Replace the empty ink cartridge immediately after the printing. The resulting print quality is not satisfactory, if printing is continued under the ink out condition.

White line across printed page

Hi Alms, Is there any chance you can post a scan of one of your faulty pages. This would help to assess the fault. If you print several pages, does the image move further and further down the page with each copy? Is the white band repeated down the page? If so measure the distance between each band - this will help identify the faulty component.
