NEEDLES DO NOT COME OUT DEEP AT ALL OR SCRATCH
It could be caused by improper handling during disinfection. Verify that the Silicone
spring/shroud looks OK. The top cartridge has a problem: The end of the silicone
spring is “crumpled up” and missing a few mm of straightness. This is caused when you
push the plunger to make the needles come out and you push a little too far/hard. This
is unfixable – the cartridge has become bad and has to be discarded.
