PIXMA TR4720 won't print in BW, faint blurry printing, lines going through content

My Canon Pixma TR4720 is under one year old. 

It continually fails to print anything in black-and-white. It has problems with everything being completely blurry or barely being visible on the page, as well as lines going through some areas of the page. 

It fails a nozzle check in the black/white section but the colored-ink sections seem to be mostly fine.

 

I have replaced the black-white cartridge, even though my original cartridge still has half ink life. 

I have run multiple system cleans and deep cleans. I have realigned the heads 

I have cleaned the inner timing belt with an alcohol swab, but also never noticed any smears and streaks in it. 

 

What else can I do? Thanks for your help

Hi,

You have done everything we would suggest. 

If the printer is in it's 1 year warranty, I recommend reaching out to Canon support for your warranty options. You will need to register your Canon gear HERE to access additional support options.

If the printer is out of warranty, you would qualify for the Canon Upgrade program. This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. Free ground shipping is included with your purchase.

If you would like to take advantage of this offer, please call our Sales Department at (866) 443-8002 Mon-Sat, 9 AM to 9pm EST excluding holidays.
