hi like yourself new to the forum, it was trying to find information on the ipf5000 that got me here.
Got my printer 7 days ago with the roller, it works very well. Originaly ordered the canon pearl photo paper so i could see how the printer performed with the canon profiles. (never crossed my mind that the printer wouldn,t have the settings for its recomended media,) It wasn't yet available in the uk and the distrubeter sent me kodak 260gm premium glossy (he thought it wouldnt matter, and its the same price) Anyway just using the glossy paper settings the results are impressive, I prefer it to the results from this printer on the a4 sheets of canon photo paper pro. Not realy had chance to work with the printer much yet but so far I am very impressed and it would seem incomplete without the roller.
Funny... It was the purchase of the ipf5000 that brought me here also! I frequent FM's site for quite some time however it is not big on printing. I too am impressed with the 5000, but here in the U.S. canon does not include the roller, you must purchase it for about $200. usd. I was going to purchase the 4800 Epson, however i decided on the Canon after hearing of some of the knocks on the 4800 whit swapping ink ect.
Best of luck with your new toy. I have always sent my printing out (i would just proof at home) so i am sure there will be a learning curve. I have had a lot of ease with the 16 bit plug-in for PS so here is keeping my fingers crossed!
