HP CQ890-67108 Cutter Assembly Kit for Designjet t120/ t520/ t125/ t130/ t525/ t530/ t730/ t830/ t230/ t250/ t630/ t650 These cutters have a common problem where they start jamming into the paper when cutting, starting with the cutters getting noisy/clattering on their travel across the paper, this is when they need replacing. These can be replaced by the user or I can service your printer and change the cutter at the same time ,ideally a designjet printer should be serviced every 12 months even if its not been used much. Please get in touch if this is something you'd like to discus, we cover a large part of the UK.
