@The Hat said it all perfectly, so I have very little to add.

Anyway, super glossy paper isn’t the best friend of pigment inks, but maybe replacing that compatible CO cart. with a new Canon OEM CO will fix or alleviate considerably the bronzing problem.
For the time being, no need to purchase practically a whole new set of carts until you find out if the printhead is OK. The nozzle test shows minor banding on DGY and C that probably will be fixed following @the Hat’s instructions, but MBK looks more like electrical damage to me, although I hope is not.

Thank you @Artur5 @The Hat
Sorry to thank you so late, I appreciate you took the time to answer.
I will get the ink that is low and do the deepest cleaning on the system. I had already done some mild cleaning to test the nuzzles. Hope the MBK is fine.
Will keep you post
Again thanks

My advice is to use only normal head cleans and not very often, (use patience) deep cleans are very wasteful of your ink and repeated deep cleans are harmful to the print head, so be warned.. Never run a system unless it is very necessary.. Keep in mind your waste ink cartridge..

First time poster.

My Pro-1 has appeared to give up the ghost. 9 of the 12 nozzle checks print fine, but I've noticed that the PBK, GY and DGY appear to have a perfect horizontal 50/50 split of light and dark, which tells me that it's in big trouble. See attachment. Initially I had thought the pattern was so uniform that that was in fact the nozzle check pattern, but the blank sections are consistent with the poor results I'm seeing on the glossy papers. Matt papers seem OK, which I assume to mean that the MBK is working OK.

I've no idea how this happened although I did try off-brand inks a few months back (co-incidence?!). Mind you I bought this printer about 8 years ago so it's probably done it's duty.

If there's a DIY remedy, I'd like to try it out, but I've tried cleaning cycles and the same pattern repeats over and over. From the posts I've read here, a DIY job is not for the faint hearted (or also time poor in my case).

Guessing I should cut my losses and get a Pro-10s? It doesn't appear to have any drawbacks compared to the PRO-1. I sell maybe 20 prints a year which tells me the PRO-1 was definitely overkill. At the time of purchase I was doing a reasonable amount of paid work, but it's mostly hobby now.

Everything you say is true, the printer has had it, but you could purchase a head and a set of carts but the cost would be just about in and around the same price as getting a new Pro 10 or second hand one.

The Pro 10 is an easier printer to work with and with much the same quality output, plus refilling can be an added bonus also, and most of the inks from your Pro 1 can be used in the Pro 10, there is no downside in getting a Pro 10, only pluses..

Sorry for your loss…:(

I’m racing through the various stages of grief, and it does seem a PRO-10s will be a worthy replacement. You mention how easy it is to fill the cartridges, so that’s a definite plus (Any ink recommendations?). Seems like it won’t suffer as much from being left idle either, which was a definite issue with the PRO-1 as being a family man makes it that bit harder to keep a printer humming.

Any insights any of you can share will be most welcome.

I’ll probably miss some of the additional detail provided by the Light and Dark Gray for the B/W prints, but truth be told it’s been a while since I made a few B/W prints, and inspected them close up.

Anyone want a PRO-1 with a busted print head?!
