[CQ] QR Codes Print Quality.

[EDSNOW]

I have a customer printing QR codes on a TASKalfa 3553 machine and the quality was not crisp / clear. Printing B/W
I did do a firmware update.
Also under adjustments I performed the color registration, toner curve adjustment, and developer refresh.
This greatly helped but unfortunately not for more than a couple of days.

Is there something more that I can do to adjust for this kind of issue?
Machine is less than six months old and very low copy / print count.

Should I adjust in a specific order?

I also advised the customer to confirm the print driver should be the latest KX 8.xxxx as a possible suggestion.

Any input greatly appreciated.
