TROY printers use a MICR toner cartridge detection sensor designed to detect the presence of a TROY MICR
toner cartridge installed in the printer. If MICR mode is enabled with the Softlock feature disabled (valid PIN
entered) and/or the printer keylock switch set to Print MICR, and a TROY MICR toner cartridge is not installed
when an attempt is made to use a MICR font, the
LOAD MICR TONER message will display on the printer control
panel and the MICR features will be disabled. In order to proceed with MICR printing, you must replace the
non-MICR toner cartridge with a TROY MICR toner cartridge, and then press
CONTINUE to proceed -- or press
CANCEL to stop the print job.
NOTE: TROY Security Printing Solutions require the use of TROY MICR toner cartridges to print MICR documents.
For information on MICR toner, refer to the TROY MICR Basics Handbook, Section 4 - Selecting Check Paper and
MICR Toner.
NOTE: The printer keylock switch is present on TROY MICR / IRD Secure EX printers only. The Softlock feature is
present on TROY MICR Secure, MICR / IRD Secure EX printers, and MICR Secure Memory Card Kits only.
Printing when toner is low may cause reader/sorter misreading at the bank due to low MICR signal levels. When
the printer is switched into MICR mode
ENABLED
and a toner low condition occurs, the printer will go off-line,
and a LOW TONER message will be displayed on the printer control panel. You should replace the used toner
cartridge with a new TROY MICR toner cartridge before you place the printer back on-line.
NOTE: To ensure consistent MICR print quality, always replace the TROY MICR toner cartridge when your TROY
printer first displays a
LOW TONER message.
Each time the printer is switched to MICR mode enabled, the print density is automatically set to a pre-
determined value required for MICR printing. If the user changes the density setting to accommodate a non-
MICR print job, the density will automatically return to the pre-determined MICR value when the printer is
switched back to MICR mode
ENABLED
.
NOTE: You can change the density setting; however, the printer will ignore the setting and use the pre-determined
MICR setting when printing MICR documents. TROY does not support any density setting other than the pre-
determined MICR density value.
