Printing on banner - two sided

Hello!

Im losing my nerves everytime i have print two side banner. I always have few problems...

1. how do you set banner to go straight all the way? when i print other side it always go straight at the beginning, but then it go more and more out of way. So when i was printing 8m long banner it was 4cm out of way at the end!!! And we re-roll it on media holder, it was rolled up straight... but it still went out of straight way!!!

2. when i print on other side, media is wriggling on front drying panel - the media doesn slip nicely! So material gets wrinkled under the head, and ofcourse head is sliding on material! And then i get stains like in picture (the vertical lines are ok!)! Do you know what i mean to tell? i don't know the right words to explain easier!

 

Aznsensation:
that would be great!

Jiarby:
Wriggling - i found that in dicitionary... how colud i explain it...? if u take a peace of paper and you put hands on each side, now go with one hand towards other hand and the paper will wriggle? this is what happen with banner. printer is pusing on one side, and on another side (front dry panel) doesn't slip nicely... i hope i explain ok!

randya:
i left it to dry whole night, and half of the day today! excually it was drying 20 20 hours!

 

how do you mean sub? you give it to someone else to do it for you?

 

i thought so to!

and i was thinking about that... but where is then profit for yourself?

 

so there istn't any simple secrets? just practicing i guess...

 

hej, i turn heaters off when i print other side...
