Pro 10s banding. This only happens in muddy mid-tones, bright mixed areas are fine. I have tried head re-alignmen.

Don't you just love rural France!

I found ordering from the Canon website is usually quicker, plus you get free delivery which is even better, then you don’t mind if there are delays.. I’m rural and everything is slow here too, but that’s how I like it..

I had a banding issue on my PRO-300, also in the mid-tones only, and also had a perfect nozzle check.

If you haven't tried it, you could reset all the settings to defaults and see if that solves it. In my case it was a paper abrasion setting on the printer that was the culprit.

Late to this but I had the benefit of historic orders to go on. Chances are that one or more of the cartridges (photo black and grey are "good"(?) candidates) has degraded ink flow due to the ink starting to clog up the mesh/sponge located in/around the outlet area.

I'll lay odds that the new cartridges will magically make the issue disappear but I'd replace and test one cartridge at a time so you can isolate the exact culprit first.

In terms of fixing from a refilling perspective it's worth flushing the problem cartridge(s) out thoroughly with a cleaning solution and flush clip, rinsing thoroughly to remove any lingering solution and then refill as per:

Note: the video doesn't show the use of cleaning solution but for poor ink flow you do need to use it to clear the mesh/sponge.

Let me know if you continue to hit problems though and we'll try to show La Poste by sending it through the Netherlands to make them look bad

Help…This Feckin Video clip doesn’t work for me.. Anyone else..

It doesn't work for me either. I have tried with Firefox, Google Chrome, Opera and Edge. In all browsers I get the same error message in Danish which translates to : "An error occurred. Try again later. ( Player ID xxxxxxxxxxxxxxxxx). Get more info"

Technical issue with the forum software it seems... I've edited the post to provide a link instead but here it is again

It looks like an ink delivery issue with one of your carts !

UPDATE!

Apologies for the late update, but I have had a terrible time with the French cartridge supply company. After 2 failed deliveries they have now reimbursed my money!

Anyway, the problem has gone! The Pro 10s is printing beautifully. I know not why?

I will update if the banding returns, thank you all for your help.

Apologies for the late update,

Thanks for the update..

Rumours that I threatened it with being lost in the returns system post-Brexit are being strenuously denied but hey, if it works...

I will follow this thread as I think I have the same problem. I use a Canon PRO-2100 with InkOwl Ink. I see the problem In the dark grey areas when I do black&white printing. My nozzle check is perfect.
I use Qimage to print and used Canson Baryta Photographique paper (310gsm) .
I tried:
- suspecting a physical contact between paper and print head, I changed the height of the print head in the media configuration tool from 'auto' to 'high' and also put the vacuum (to hold the paper against the platen) to 'strong'.
- I did a paper feed adjustement from within the media configuration tool.
- I printed at max. quality (600) and overdrive (1200) (no difference)
- I used the internal driver monochrome setting
- I printed directly from within photoshop in stead of from Qimage (no difference)
- I ran throug a cleaning cycle (no difference, understandable because the nozzle check was perfect)
- I exported to a jpg to see of the problem was jpg artefact related (no difference)
- I tried unilateral printing in stead bilateral (was even worse)
- I changed the amount of ink used in the media configuration tool from 'medium' to 'low' (was worse)
- changed the amount of ink used to 'high' (better now but the lines were still visible)

At the end of the day the problem is not solved but the lines seemed to be a little less prominent by increasing the amount of ink used and probably by the paper feed adjustment.

Any thoughts ? Should I suspect the InkOwl black and grey inks ?
