While not in the UK myself I am sure there are a great many experienced people here with either a Z2100 or 3100 who would be happy to help.
If you explained your problem a bit more perhaps you can find a solution through this forum.
Thanks. I didn't want to clog the forum with potentially simple problems! but here goes.
I've 2 issues at the moment. The first is that the prints are much duller/darker than on-screen. Even from CS3 with soft-proof on I have to push the lightness of the screen image to get a reasonable print. I was expecting prints that jumped off the page - and saw some at a recent show in the UK. I'm using an iiyama prolite B2403WS and huey to calibrate, and have run all the profilingprinter calibration for the paper(s). Currently using the HP ID satin.
The second issue is banding on black. Having run several cleaning cycles, and finally removed and cleaned the printheads (the black was very dirty and had a 'blob' of congealed ink on one corner) I am still getting some 'carry-over' for example on the edge of a print or into a white section. I cannot see anything else to clean (I did clean the plate the heads sit on (righthandside of machine).
Running the diagnsotic image the bold colours look fine, but I can see some breaks at MK 464 lefhand bar, 528 lefthand bar 112 righthand bar 500 righthand bar and C 384 lefthad bar. PK 576 lefthand bar, LC 176 lefthand bar. LG 544 left and righthand (2 on righthand.
I don't know the significance of this. The heads are in-warranty.
Note I did have an issue of the printer stopping every 4" or so when printing out of Photoshop, but the latest firmware and driver seems to have sorted that. On dark images it was leaving a visible band. now this is OK.
