Pages are being printed blurry printer is pc850

First, try to clean the print head by following the steps below:
1. Remove the old ink cartridges and clean the print head nozzle with a damp cotton swab to remove any dried ink.
2. Reinstall the new ink cartridges and print a test page.
3. If the test page is still blurry, try running the printer's alignment utility. This is typically accessed through the printer's settings or system preferences.
4. If the alignment utility doesn't help, try manually doing an alignment page directly from your computer. Be sure to follow the instructions from the printer manual or from the printer manufacturer's website.
5. If the alignment page is still blurry, try reinstalling the cartridges to ensure the cartridges are securely in place.
6. If all else fails, you may need to replace the ink cartridges

Hi Steven Quick im happy to help you

When you say many documents, we talk about an amount of 200 pages, this is the case, you need to replace another cartridge.

If not that much, I can recommend to clean injectors to try to solve the problem, if you have clogged nozzles.

How to clean the print heads on your canon printer

http://www.en.rellenadodecartuchos.com/2014/05/how-to-clean-print-heads-on-your-canon-printer.html

I have a Canon printer. Whenever pictures or text gets a double or blurry image I open the printer solutions menu. It sounds as though there is a problem with inkjet alignment. By clicking the realignment button the printer will automatically realign the jets. I usually test the alignment by printing a page from that program. All the line segments should line up.

Hi
Check the ink levels on the cartridges and replace dry cartridges.
Also,try cleaning the 'printhead'

Don't replace but verify the condition of fuser assembly, if you found any cracks or folds on teflon roller or pressure roller causes the same thing, just verify get back to us...

Put back the original cartridge and print a page. If it is not blurry, you bought a bad cartridge. Take it back for exchange.

use the printer tools like head cleaning tools etc.

Hello,

You have a bad drum. Return the drum for a replacement and you should be good to go.

Hi,

Is it the ink cartridge contacts you already cleaned? If so, then you can also clean it using the tools menu from the printer panel:

-press setup menu, then go to tools
-select clean print cartridge and press ok
-it will print a test page. If the printout is good, you can try printing again.

I hope this helps.

Regards,

model of the printer ? sound like a
heating device problem.
