Z-fold paper

Also called: Fan-fold paper

Z-fold paper — Recording paper folded concertina-style into a pack, so ECG or CTG records come out as separate pages that are easy to file.

Most 12-lead cardiographs and fetal monitors use Z-fold packs. The pack size, fold length and the position of the black sensing marks must match the machine, or the recorder will stop or print across the folds.

Rolls are used by smaller single-, three- and six-channel recorders and by some monitors.
