Use the print alignment feature and follow the directions precisely. If the print heads won't align properly to get a clear image in the self-tests... get a new printer. It isn't worth repairing. If your cartridges are fairly full, buy another Canon that uses the same cartridges and install them on the new machine... keeping the unopened ones for spares. This will help defray the cost a little.
The error indicates something blocking the cap wipe assembly from going up and down.
Did you shut off the machine while it was warming up, or purging it self? If you did the printhead is probably stuck to the cap wipe assembly and need to be separated (gently) so that the cap wipe can move up and down.
The blurry prints are from oil on the encoder wheel, clean the encoder wheel and you will be fine.
The printed output is fuzzy, blurry, or grainy, or the edges of objects in the images are jagged.
Follow these steps until the issue is resolved.
Step one: Check your paper
Many papers have printing and non-printing sides. Load the paper with the printing side down.
Use the correct paper type for the project. For everyday documents, plain paper works well. For documents with dense printing, such as high-contrast graphics or photographs, use HP Advanced paper for the best results.
If these steps do not help, try a different paper. Ink might not bleed as easily on heavier paper. Paper that does not accept ink well is also prone to bleeding and smearing. HP designs its inks and papers to work together.
Step two: Check the settings
In the program being used for printing, click File , and then click Print .
The Print window opens.
Make sure the appropriate product is selected, and then click Preferences or Properties .
The Preferences/Properties window opens.
Click the Printing Shortcuts tab.
Consider modifying some or all of the options in the Printing Shortcuts menu to increase print quality.
Print quality : If the quality of the printouts is not acceptable, try increasing the print quality. To print more quickly, try decreasing the print quality.
Paper type : If one of the options matches the paper type exactly, select it instead of Automatic .
Paper size : Make sure that this option matches the paper loaded in the product.
To see additional options, click the Advanced tab, and then click Advanced Features .
The Advanced Features window opens. Consider changing the following option:
Ink volume : Adjust the amount of ink that prints on a page. For lighter images (less ink), drag the slider to the left. For darker images (more ink), drag the slider to the right. The lighter the ink volume, the more quickly the printout dries.
Step three: Check image resolution
Make sure that the image file has enough resolution for the size of the printed picture. Although many photo applications can enlarge an image or part of an image to any size, eventually the individual pixels become visible and the whole image looks blurry.
Here are some general guidelines for image file resolutions:
94 pixels per cm (240 pixels per inch) for images to print on smaller format photo paper, such as 10 x 15 cm (4 x 6 inch)
117 pixels per cm (300 pixels per inch) or higher for larger format photo papers
Lower resolutions might produce acceptable images when printed on rough-textured paper
Step four: Align the cartridges
If the previous steps have not improved the appearance of the printout, align the cartridges. See the user guide for alignment instructions.

Yeah , that is most likely the problem. If ou remove the right side cover , there is an encoder on the end of the drum motor shaft, It becomes contaminated with the silicon from the maintenance kit. Fixing it requires you to pop the encoder off and flush it well with alcohol. It is unlikely is has failed, but when dirty is causes the drum to turn at the wrong speed.
I will offer some thoughts.
But thats weird .
Have you tried a new driver? Yeah I know, that doesn't make a lot of sense to me if the image is fuzzy, but since it will print a internal pattern clear and not a print sent from the computer, the driver may be the issue. I stress MAY be the issue. What I suspect more is the drum encoder. When I hear about that machine bluring, that is the most likely cause. It picks up silicon lubricant from the maintenance kit and normally causes blurrs.
It is on the right side of the machine ( viewed from the front), track it from the drum shaft. It has a clear plastic cover over it, but it needs to be cleaned with alcohol to disipate the silicon lubricant from it.
No no not drinking alcohol, although that can make prints blurry LOL.. Hope you have a sense of humor. To many people today don't....................
Try this: make a copy and stop it when it reaches the cartridge ( has to have image on paper) take out paper and look at it, does it have blurry copies? if yes, then the problem is with the cartidge or (worse) the laser printing device ( expensive).
Take a chance and replace the cartridge. if still there you need to replace the laser unit.
If it does not have blurry copies when you stop it at the drum then check the fuser unit( doubt it ) to see it it has any writing or toner on it.
