I ordered a Pro-4000 from ITsupplies.com and happy to report a great experience. Their listing stated ships with 330ml ink tanks https://www.itsupplies.com/Canon-imagePROGRAF-PRO-4000-Printer-44in-Wide-Format-1127C002AA Other online retailers state ships with 190ml tanks. I reached out to ITsupplies before ordering and they confirmed 330ml ink set so I made the purchase 10/16/2017.
10/23/2017 it arrived at my home via tractor-trailer (semi) . The shipper was great, called to arrange delivery day and time frame. I asked they have a pallet jack to get into the garage and they obliged.
Two of us handled carrying the printer just fine but it's place in the home is up stairs which required 3 of us to lift on end as it has a tight corner, rest was easy.
On to the inks as it was the big reason I chose to order from ITsupplies. Now looking on Canon's web site they show it shipping with 300ml starter set. https://www.usa.canon.com/internet/portal/us/home/products/details/professional-large-format-printers/professional-photo-fine-art/imageprograf-pro-4000
All other online retailers showed 190ml, which is what mine came with. I wrote an e-mail to ITsupplies and they quickly replied it must be older inventory and they contacted Canon on my behalf and a full set of 160ml inks arrived 11/01/2017 for a total of 350ml of ink. Very happy with the timely replies and action taken.
The printer itself I am very pleased with so far. I was up and running pretty quick to use canon papers. It did take some time to learn how to fully get Breathing Color AM1x media settings on both the printer and lightroom classic cc. Then getting XPS which allows the printer to accept images files greater than 8bit. Installing the Print studio pro plug in for LR classic CC gave me issue too. But after all of that was figured out with help here on this forum and LL I am up and running.
I have only printed from a sample pack of paper from Breathing Color and have some rolls due to arrive today. I have read many complaints on using cut sheet paper on the Pro-2000/4000/6000. My experience so far is that it is ok. I get an out of alignment error now and then but usually feeds and ready to print. I have a few rolls due to arrive today so looking forward to that experience.
Canon has a rebate in the USA currently for $300. I was very pleased one is able to fill that out online with attaching the receipt file. Status of that is approved but waiting for arrival.
Keith Cooper has fantastic write ups, one on the Pro-2000,4000 as well. http://www.northlight-images.co.uk/canon-pro2000-setup/
If you are looking at a Pro-4000 I would inquire about the ink set shipped from who you purchase from. They use to ship with 190ml and currently per Canon ship with 300ml. Very worth the inquire in my opinion.
Cheers,
