    The nozzle check is fine, when I go into Maintenance Mode, and do the Head Alignment checks - Head Skew/ F & B etc.... when I print these tests I notice the lines are off and not straight - image attached of some runs I have done now....

    Front to back alignments are off.
    Probably slants and timing adjustments as well.

    Needs mechanical and electrical adjustments.

    Alright I am getting somewhere one thing I noticed is that the rollers aren't feeding the media through properly,, what would cause that???

    What I have done is removed all the heads, cleaned them, went through all alignment test etc.... now the double image is like a fraction of a millimeter off???

    Yeah done plenty feed adjustments, slant adjustments, Bi-Dir adjustments, UNI-Dir adjustments etc.... but not sure if it is the rollers that are doing this or the roller motors that hold the Roll of material???

    Trust me I have done so many test prints, adjustments and the like today, it is printing SEMI-okay when I have the END of the material coming out of the machine attached to the Take-up mechanism then the matching seems to feed pretty well, but there is still a millimeter off on the alignment ......

    I quess the question is why do you think it is a feed issue?

    You didnt mention Front to Back alignments?
    Are those good?

    The front to back alignments are pretty much spot on, this could still be the issue I am having but everytime I start to tweak the F & B something else will go funny :) :)

    I may have missed it but what material

    What material are you printing, is there any drag ( heavy roll ) or pull ( using a take up. that can cause material feed errors. IS there a material thickness setting ( did you check the thickness of the material, measured )


    also banding ( I am guessing its a mild solvent machine ) is usually cause by dot gain by improper media temp before printing. Too low.

    Feed rollers are clean, if you load several small width pieces of the same material across printer and pull each , do any slide easily ?

    side to side double images are bi dir related can be easily verified if you print in uni dir and problem goes away. Verticle double is material either slipping through or head ( carriage skew )

    1. I normally use a HEXIS or LG digital vinyl....
    2. Yes lots of banding, Mild Solvent printer, So temps should be higher...?
    3. Will clean rollers, also there is a bit of slide when I pull the media....
    Thanks for the info will post back here my results
