Soljet Test Print Help

[jason91]

Please help me trouble shoot this test print...Its a roland soljet pro 2 sc 545ex....
1. The first pass on the print is ok except the light cyan (one side isn't printing)...But on the second pass there is many dropouts on the cyan , yellow, and light magenta
Why is there no drop outs on the first pass, but only on second pass?? Whats going on with one side on the light cyan head? I've ran several cleanings, even pulled ink through the captops? Changed data cables, checked fuses? Any ideas? please help

That is quite poorly what make inks
Looks like it's been standing to long and the pumps and caps not doing their job correctly. To me it does not look like a electrical fault

That is pretty odd for it to fire the second pass so differently than the first.

First up, that light cyan. One side not firing at all is either an empty ink cartridge that isn't beeping at you, or a popped seal on a damper. A less likely 3rd possibility is an ink line or connector on the ink line has ruptured.

Why the second pass is missing so much is a bit more of a question. I'd lean towards the dampers, maybe start with changing them on one group (group a for example) and see if that causes a noticeable improvement. It could also be a clogged manifold restricting ink flow.

All the dampers are new? Just replaced all 12 of them

put the old dampers back...test pattern is perfect except that one side of the light cyan...What could cause this? Ive changed data cables? I know its not the head because it was working in another printer, and I just swapped it over to this machine?

the only places that can affect one side of a print head on that machine are cartridge, ink line, damper, manifold and head itself. the caps + pump would be shared with the other side, or with the pump its group neighbor.

empty ink cartridge, broken ink bay needle, craked ink line, broken manifold tip, clogged manifold, or electrically damaged cable/head are all possible reasons to be missing every single nozzle on one side of a head.

Ive checked everything you said....Took the head out and moved it..It works in another slot, but now the head I moved to that slot...one side doesn't fire...Its gotta be electrically? Ive put tried 3 different data cables on that one side..Still wont fire?? If it was a fuse that whole group would be dead...What could it be print caridge board? Is there away I could check it?

cross the data cables on that head, see if the missing side changes to the other side. It might be easier to cross them on the print carriage board, if the cables on the head end don't have enough room for that.
