TROUBLE SHOOTING
9.6 Error Messages in HP-GL Command Mode
If any of the HP-GL command error messages listed in the following table is displayed, the cause can
nearly always be traced to one of the causes below:
(1) The software applicationʼs output device setting has changed; or
(2) The plotterʼs interface conditions have changed.
If a command error occurs while the COMMAND setting is HP-GL, therefore, first check the two corre-
sponding points below.
(1) Configure the software to drive your plotter and ensure that the softwareʼs interface conditions are cor-
rectly set; and
(2) Re-specify the plotterʼs interface conditions.
