If you use a table outside this range, you reduce efficiency or stability, and may
have to monitor printer operation.
Operating and Service Clearance
You should provide adequate space for cooling air, and for operating or
maintaining the printer. This is also helpful if you will occasionally change the
attachment card. Often, as little as 450 mm (18 in.) of extra table space (or floor
space, for a printer on the optional printer stand) is adequate to service a printer.
Symbols that appear in specification drawings are defined in the following table.
