Pixma 5420 all-in-one printer doesn't print black ink or copy anything

[LK1345]

I've cleaned and deep cleaned this cartridge (it's the large one, 250XL PGBK) but to no avail. When I print a test sheet all the colors show up except the large black one. I just replaced all the ink cartridges and the printer utility shows I have enough ink in all of them. I also cleaned the print head (per instructions on a YouTube video), but it stil doesn't print or copy. I'm at my wit's end to find out how to fix this issue, so if anyone can help I'd be grateful.

Hi,

Based on your description, you have done everything we would suggest. The issue is with the print head and since the MG5420 was retired, the printer would need to be replaced. 

I would recommend 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.
