сервисный код 49.5001 Service Error. Аппарат выдает его и зависает. Что он значит?

Описание (Description)
A critical firmware error has
occurred that caused the
processor on the formatter to
abort the operation.
This type of error can be caused
by invalid print commands,
corrupt data, or invalid operations.
In some instances, electrical
noise in the cable can corrupt
data during transmission to the
printer. Other causes include
poor-quality parallel cables, poor
connections, or specific
applications.
Sometimes, the formatter itself is
at fault, which is usually indicated
by a 79 SERVICE ERROR.
