This is because these are true power supplies and not a wall-wart.
Some of the early zip drive power supplies are linear and use a standard
LM7805. These look like wall-warts since they still have a large
transformer in them. The later generation power supplies are very small
switching power supplies.

All of this is off-topic, but I've got three different types of Iomega
ZIP drive "wall warts" here (all voltages unloaded, measured from
my Fluke 8020A):
57DR-5-1500(A) outputs 5.21 volts DC
48DR-5-1000 outputs 5.11 VDC
91-56403 outputs 5.15 VDC
Much closer to spec than most wall warts. Zip drives use one that is 5 VDC. Do they really
need 5?
IIRC, the Zip-Drive 'wall wart' is actually a complete regulated power
supply. So to operate the logic, it DOES need to be 5VDC.
