An invalid option parameter (a value outside the valid range for the option) will result in the following message. The example shown indicates that the parameter value for Option #45 was not in the valid range for that option:

DOWNLOAD ERROR - BAD DATA FIELD VALUE 45=X

X THROWN AWAY

In the event that this message is printed, the user must resend the command sequence for Option #45 with a parameter value in the valid range for that option.

An invalid separator message indicates that the option number and the parameter value were not separated by an equals sign (=):

DOWNLOAD ERROR - BAD FIELD SEPARATOR

PFS downloading commands take the following format:

Trigger 1 (the cent sign ¢ is the default) - percent sign (%) - PFS # - hexadecimal data pair(s) - percent sign (%). Note that the percent sign both initiates and terminates the downloading sequence. No spaces are allowed.

For example, if Trigger 1 is the default cent sign (¢), the following sequence will define the PFS 0 — Power On Sequence as the hexadecimal pairs 31h and 32h:

¢%03132%

The cent sign (¢) is Trigger 1; the first percent sign (%) indicates that the following character sequence is a PFS configuration command; the numeral zero (0) indicates that the PFS to be defined is PFS 0; the numerals 31 and 32 are the hexadecimal pairs that will be sent to the printer when this PFS is invoked; and the second percent sign (%) is the terminator.

To replace the definition of a PFS, download a new definition. To delete a PFS, replace the definition with a space (the ASCII space character is 20h). For example, the following sequence deletes the contents of PFS 0:

¢%020%

PFSs are restricted to a maximum of 76 characters. The custom banner (PFS D) is entered as text, rather than as pairs of hexadecimal characters.
