90% of the problems with CISS is with AIR in the system...
you MUST prime these systems (carts) BEFORE you put it in the machine.
you dont prime first, you not gonna get it working right period !
also check hoses/tubes for pin holes, yes pin holes !!!
all the epsons we have had over the yrs we been in this game, never had any with the major banding issus that the 3 ricoh's have sitting here - NEVER.
one machine, one would say...ok, you will get the odd bad apple, so to speak...two machines with same fault, you start to think...on no, cant be can it ?...and finally, when you buy another 3rd machine, and its the same as the 1st two, you then come to the sad conclusion that would have been better spending that £200 you spent buying these dam things, getting rat assed down the pub
so if you all on here can say "ricoh" the best printer for sublimation" can tell me why we got 3 brand new sealed in the boxes duffers ? as i said before...RICOH know about this and are still selling the bloody things....
go research guy n girls on the net and it will be apparent the banding issues with these printers
as with any machine, maintenance is the key here as well to longevity of printers. thats why our wee epson wf3520's, have lasted us, and still going ( just ), after 2 yr of heavy sublimation pounding...and we still got our original brother printers, and yes, they still print with sub ink...we just dont get the deeper reds, blacks as we do with the epson 1500, or even with the epson 3520's, so they are used only for office work, flyers, invoices etc ( with dye inks )
but bare in mind, all these epson and ricohs etc, they were not built to have the thicker sub inks flowing though them...so it obviously gonna take its toll on them - eventually
you all have a great day
