Hi Gryphon69,Hi Remko,Gryphon69,There are reports of banding issues also for the x600 line, where users suggest it may be caused by ink starvation due to a potentially faulty ink pump:Well yeah.I think that this change in pace is due to a mounting number of user complaints about the banding issue
But am I right that this is only the Pro-1100 and not the -2600 and -4600, or is it just that there are far more of the -1100s out there?

It is great news that finally Canon is acknowledging the issue. About time!
I have a PRO-2600 since mid January and have not seen any banding in any of my prints.
There are of course differences in technology between the PRO-1100 and the PRO-x600 printers. One of them is that the bigger printers have sensors on the printer head carriage that constantly check the paper advancement during printing and correct on the fly if needed.
Canon's USA David Rice have said that paper feed adjustment therefor is no longer needed at all on these printers. And Canon here in the Netherlands acknowledge that to me when I asked. David Rice mentioned it in a video made by Lexjet.
I do hope the issue with the PRO-1100 will be solved soon!
Cheers,
Remko
Thanks for weighing in - this is very interesting!
If I am not mistaken, Canon large format printers have (or used to have?) a setting where the user could choose between a paper feed rate that would prioritize speed or quality (with the quality setting being meant to minimize banding). Does your 2600 still have that setting or has it been replaced by the optical-mechanical system that you described (which sounds very cool, I’d say)?
I agree that it was about time for Canon to acknowledge the banding issue with the Pro 1100 - it took them almost 6 months in my case. I am glad to hear that you don’t have to deal with that problem with your 2600 and hope that some day I will be able to say the same about mine too! ;-)
Thank you for your kind words.
I do not recognize what you are asking about being able to adjust the paper feed rate. I am not at my printer atm so cannot check if it is a menu based feature in the printer itself or something in the driver.
If I understand you correctly, than my assumption is that such a feature is redundant with the x600 line of printers as the sensors on the printer head carriage should auto correct for that. Dave Rice from Canon even gave the example of a user setting the wrong core diameter of the roll by mistake: a 2 inch core instead of a 3 inch core. The printer would automatically adjust the paper feed rate for that.
The quality versus speed paper feed you mentioned sounds to me as a choice for unidirectional printing versus bi directional printing. I use Mirage for printing. It has the printer driver incorporated in its software. Some features that the stand alone driver has, are not available in Mirage. Like the choice to select unidirectional printing. If I use Qimage than that choice is available of course.
One of the things I would do as a test when having banding is - apart from a paper feed adjustment if printing on the previous generation of large format printers or the PRO-1000/1100 - is to choose unidirectional printing. At least on the Epsons that is one of the things you would do when experiencing banding.
I have only read about one occasion where a user with a PRO-2600 complained about banding. That was on the site of Canon US. The reply from someone else was that the attached photos look like an issue of ink starvation. Which, if correct, is not banding. I have not heard from anyone else having banding issues with these new large format printers.
That does not mean there aren't any of course. But to me it might point in the direction of an issue with the paper feed mechanism with the PRO-1100. Especially when I searched for it and only the aforementioned case with a x600 printer came up. I am a member of a Canon Large Format Printing Group on facebook that is very active. And nobody there ran into such a banding issue with the large format printers.
I do mention the banding issue with the 1100 in other printing groups on facebook when people are asking for advice which A2 printer to buy. And post also a link to this discussion on DPReview. So they can make an informed decision. And the issue gets hopefully also more attention as in one of the facebook groups Canon US people are actively involved as well.
I wish that Canon comes up quickly with a good solution!
Cheers,
Remko
