MG5460 blurry vertical printing with PGBK ink only?

[arzasa]

Hi All,

Have a not so old (replaced an old MP830 which rocked!) MG5460 printer which has an issue printing vertical stuff aligned correctly, but only in the PGBK ink.

So on the printers test page, at top is the PGBK test with a grid of lines, horizontal and vertical, it is about an inch in height. So at the top of this grid the vertical alignment is fairly accurate, then about the 4 horizontal down it starts to deviate for a few horizontal lines, and then starts to come back into alignment.

Have done head alignments although only thing i'm not sure if is when it says insert specified paper, is that anything special or just plan copy paper??

Any other suggestions or is it a send back for service?

I have a scan of the printers test page here http://tinypic.com/r/2eg5yr6/8

Thanks all

Im having the same problem. My printer is a MG 5420, but only the PGBK lines are blurry. Ive changed the ink twice, could the head have gone out already? It's only a little over 1 year old.

Dear friend, if you are using original cartridges perform the cleaning process to print head If the rest of the current score there is damage to the print head

I watched a video on You tube yesterday on how to clean the head. I cleaned it last night, and it actually helped fix the "blurryness". Thanks for responding, Joe

Can I ask which video you watched so I can try the same on ours?

In the end, we just bought a new MG5560 printer, but would be good to get the 5460 going again as it was, like yours just over a year old.

Once you get the head out follow this guys directions.

Hello! I had the same problem on an MG7170. Tried everything in the canon FAQ and nothing worked. I was going to throw the printer away when someone pointed me to "extreme printhead cleaning". I was told it was how the printer repair shops (not canon authorised) do it. With nothing to lose, I tried it and it totally worked! The printer now prints like new with perfect alignment on all colors including PGBK.

Here's the video illustrating the method:

Note: Pay attention at around 8:35. You must flush until you get a clean, smooth spray to clear all clogged particles because the clogged particles are what's causing the jets to misalign.

If you have a spray steamer (I don't), you can try that too:

Good luck!!

Note1: This problem has nothing to do with the encoder strip otherwise it will misalign on all colors.

Note2: This problem mostly happens on PGBK because pigment ink unlike dye ink dries with a hard residue.
