MG6821 PGBK Print Nozzle Problem

I have a one month new MG6821 printer. The printer works fine in the beginning, until today all black printouts have double lines. I ran print head clean and deep clean, doesn't help. I have also ran print nozzle check pattern, please see below photo. Does anything know whats going on?

Re: MG6821 PGBK Print Nozzle Problem

I have the same problem on my MG7150 which is a few years old now.

My page count is up to 8401-8450.

I suspect this is a fault with the PGI part of the print head.

My printer is well outside warranty so was about to bin it and buy a new one but I have found a workaround.

It only affects the PGI black which is the normal black used for text.

I have set my print preferences to always print in 'Photo' mode by default.

My prints are now all fine.

OK I know I have just bypassed the PGI tank but this is OK for me as my prints are now sharp.

I also refill my cartridges and for a while now I have put dye based ink into both black tanks anyway.

I did originally refill the PGI tank with pigment black but stopped buying two types of black for convenience a while back and I really can't tell the difference anyway.

With your printer being so young, I would just return it (I suspect you already have!!).

 

I thought the problem may be a print head indexing problem but since my printer is fine now I have set it to 'Photo' only, I suspect it is a fault with the nozzle timing for the PGI part of the print head. I suspect a new print head will be as much as a new printer so I will run my printer in 'Photo' mode and see how long it lasts.
