PIXMA MX922 PGBK 250XL ink tank has double letter effect

I have a MX922 and only the 250xl cartridge prints double letters. I did the auto and manual alignment several times with no improvement. I cleaned the timing strip and tried 3 different 250xl ink tanks. I did deep cleaning several times. I inspected the slot where the ink tank goes for dirt or debris and could see nothing. When I forced the printer to use the BK (CLI-251) ink tank the lettering came out perfect. I don't know what else to do. The printer is barely 2 years old.

I have gone through this forum and noticed that this problem is very common. One would think that a Canon technician would look into it, figure it out (I strongly suspect they have) and post a solution like: "You need a new head" or "you need to replace part #xxxxxx" or something. Instead we get: "we're not going to tell you what's actually wrong with the printer so shut up and buy a new one."

Same exact issue for me, I noticed it a few weeks ago, it wasn't horrible... but it seems REALLY bad today.

The ink seems to be ok with the other colors, and the smaller black ink. It's the fat one, 250XL (which I guess is the one that prints text) I'm having issues with all of a sudden. Everything I print shows a side by side like a "ghost text" letters, - the text almost look doubled. I tried the print align, deep clean, even another printer ink cartridge and no luck.

It appears to me to be a print head issue that shows up after printing a certain number of pages. It gets worse from that point on. I suspect you need to replace the print head.
