Bubble Jet S400 issue : dummy lines printed

[karl101]

Hello Experts

Following an issue with my MG5350 that print only blank pages, i decided to use back my old S400 printer.

And i have a little issue that you can see in the attached image.

The printer adds colored line at the begining and at the end of the printed zone.

Do you have an idea on how to fix that ?

Thank you very much for your help
