My printer HP LaserJet Pro M404dn prints black stripes, about 6cm long, every 3cm (11 stripes in height) on the left print side. Does anyone know where this comes from? Thanks for the help

Helpful answer

Either rubber rollers are to blame for this or it comes from the transfer unit, which could also be dirty. You could clean the transfer unit, but you should not touch it with your bare fingers, it is best to wear rubber gloves. There may also be some toner residue inside, which should be carefully vacuumed off.
