If at anytime the position of the MICR Keylock does not correspond to the installed ACOM supplied toner
cartridge, the printer will stop the print cycle and the printer's Control Panel LCD will display... LASER
FAILURE, POWER ON/OFF. When this error message appears, the printer's power must be reset
(turned off & on) in order to clear the error. After the printer's power has been reset, install an ACOM
supplied MICR or NON-MICR toner cartridge to continue printing. Remember to make sure that the
MICR Keylock position corresponds to the installed toner cartridge. When the MICR Keylock is switched
to the ON position, a MICR Toner Cartridge must be installed, otherwise the Laser Failure Message will
be displayed; and when the Keylock is OFF, a non-MICR Toner Cartridge must be installed.
CAUTION Any data, fonts, signatures, logos, forms, or macros downloaded to the printer prior
to getting this error message will be lost! Since the printer's power must be reset,
the printer's memory is cleared of any information. Once the printer's LCD displays
"READY", you must first download your fonts to the printer before restarting your
print job again. If you are using an ACOM SECURE-A-FONT Module, the PCMCIA
card must be removed and reinserted into the reader. This will download the stored
data from the PCMCIA card to the printer's memory.
NOTE: If your printer's Control Panel LCD displays the LASER FAILURE, POWER ON/OFF error
message after installing an ACOM supplied MICR or NON-MICR toner cartridge, please call
ACOM TECH SUPPORT AT 1-800-217-ACOM (2266) for assistance.
