8.6.6.4 Magnetic Non-MICR Toner Sensor
Only the model 2 printer has the NON-MICR toner sensor installed. (See Figure 8.6.6.3.2-1). After the
NON-MICR sensor is in place in the printer, one lead from the sensor is looped into the EP Cartridge
Interlock Switch Assembly, PL 7.2-23 (See Figure 8.6.6.3.2-2) and the other sensor lead is connected to
the MICR KEYLOCK. (See Figures 8.6.6.3.2-3 and 8.6.6.3.2-4)
The model 2 printer while in the MICR OFF mode will only function when an ACOM supplied NON-MICR
toner cartridge is used. The sensor identifies the ACOM NON-MICR toner cartridge by sensing the
magnet that is installed in the toner cartridge. If an OEM or non supplied ACOM toner cartridge is
installed in the printer, the print cycle stops and the printers Control Panel LCD will display the LASER
FAILURE POWER ON/OFF error message. Once the printers power has been reset and the correct toner
cartridge installed, the printer will then function.
8.6.6.5 MICR Mode Keylock
Only the model 2 printer has the MICR KEYLOCK installed. After the MICR KEYLOCK is installed in the
Front Right Cover, PL 1.2-3 (See Figures 8.6.6.3.2-3 and 8.6.6.3.2-4), the 3 separate numbered
terminals on the keylock are connected as follows
1. The #1 terminal on the keylock is looped into the EP Cartridge Interlock Switch Assembly (PL 7.2-23).
2. The #8 terminal is connected to one of the MICR toner sensor leads.
3. The #3 terminal is connected to one of the NON-MICR toner sensor leads. (
See Figure 8.6.6.3.2-4
)
The position of the MICR Keylock determines the mode of the printer. The mode of the printer must
correspond to the installed toner cartridge in order for the printer to operate.
For example; if the Keylock is in the MICR OFF Mode (“12” & “6” O’clock position), the printer will only
function if an ACOM supplied NON-MICR Toner Cartridge is installed into the printer.
If the Keylock is in the MICR ON Mode (“9” & “3” O’clock position), the printer will only function if an
ACOM supplied MICR toner cartridge is installed into the printer.
NOTE: When in the MICR ON mode or “9” & “3” O’clock position, the actual key can not be removed
from the MICR Keylock. The key can
ONLY
be removed when in the MICR OFF mode or in the
“12” & “6” O’clock position.
CAUTION If at anytime the position of the MICR Keylock does not correspond to the installed
ACOM supplied toner cartridge, the print cycle stops and the printers Control Panel
LCD will display the LASER FAILURE POWER ON/OFF error message. Once the
printers power has been reset and the correct toner cartridge has been installed with
the MICR KEYLOCK in the corresponding position (
MICR ON or MICR OFF ), the
printer will then function.
