Please note that the new office equipment is extremely fragile.

"Equipment" is an uncountable noun in English. It refers to a whole group of items as a single concept, so it cannot be pluralized (no "equipments") and always takes a singular verb (is).

Furthermore, one of the new printers has already jammed because someone tried to print a sandwich recipe on cardboard.

The phrase "one of the..." must always be followed by a plural noun. You are singling out one item from a larger group of many items, so it must be "one of the printers" (not "printer").
