Source Technologies ST9510 manual Micr Commands, Fonts and Secured Resources, PJL Unlock Sequence

7. MICR Commands

The following are the key PJL and PCL commands required to access MICR resources in the printer. For the complete source of information on PJL and PCL languages, consult the Lexmark Technical Reference documentation.

PJL MICRJOB

Each MICR printing job should include in the initial string of PJL commands, the MICRJOB command. The command forces copy count = 1, and Jam Recovery = off. The format is @PJL MICRJOB(0D)(0A)

Fonts and Secured Resources

The ST Secure MICR printer has four fonts password protected in FLASH memory. The printer requires PJL commands with the correct password value to unlock the font resources, followed by PCL to print the fonts. They are then re-locked by PJL commands or by a printer power cycle.

The PJL commands to unlock the fonts must precede all PCL commands. The re-lock PJL commands must follow the PCL commands and final form feed command. The PCL commands could print an unlimited number of pages between the unlock and re-lock sequences. We will use <ESC> in the following examples to indicate the Escape character, ASCII 27. Values shown in parentheses () are hexadecimal.

PJL Unlock Sequence

<ESC>%-12345X@PJL LDECLARE LRESOURCE:”flash:” LRWLOCK=”PASSWORD” 0D)(0A)@PJL ENTER LANGUAGE=PCL(0A)

The sequence contains a UEL (Universal Exit Language) command followed by the unlock and enter language commands. The commands are case sensitive. PASSWORD is the initial ship default password value. The command delimiter is a Line Feed (hex 0A) with Carriage Return (hex 0D) being optional. Spaces are required as shown. The ENTER LANGUAGE command is optional but recommended. The command should also end with a LF (hex 0A). At this time all secured resources including any resources that are customer unique in FLASH are unlocked and available to PCL.

The password value is limited to no more than 8 alphanumeric case sensitive characters.

PJL Re-Lock Sequence

<ESC>%-12345X@PJL LDELETEPASSWORD LRESOURCE:flash:”(0D)(0A) <ESC>%-12345X

Sent after PCL, this sequence re-locks the resources with no change in the password value. The PJL syntax of LDELETEPASSWORD is not the password. The command sequence terminates with the UEL command (Universal Exit Language). This is optional but recommended.
