SENSOR KIT
Intermec offers a kit containing two sensors, that detect the rotation
of the paper supply spool and the ribbon unwind shaft and update
two counters, one for each sensor. By means of custom-made
application programs, the counters can be read and used for indicate
paper-low and ribbon-low conditions (as opposed to out-of-paperout and out-of-ribbon conditions, which are supported by the
standard error handling). See SYSVAR system array in Intermec
Fingerprint 6.13 Reference Manual1.
The Sensor Kit is available for the following printer models:
Model Ribbon Low Sensor Paper Low Sensor
EasyCoder 501 E yes yes
EasyCoder 501 SA yes yes
EasyCoder 601 S yes no
EasyCoder 601 E yes yes
The sensor kit consists of two photo-electric sensors and two #T10
Torx screws.
The sensors require no regular cleaning. However, should any
malfunction be detected, you may try to blow the sensor clear from
dust or paper residue before replacing it.
The sensitivity of these sensors cannot be adjusted.

Installation
Ribbon Low Sensor
• Open the right hand door.
• Turn off the power and remove the left-hand cover.
• From the paper compartment side, insert the connector and cable
through the square hole in the centre-line wall.
• Insert the sensor under the code disk of the ribbon unwind unit so
the disc will run in the U-shaped slot between the receiver and
transmitter.
• Attach the sensor to the centre-line wall by means of one #T10
Torx screw. Check that the code disc can rotate freely.
• Connect the cable to connector P-605 at the top of the CPU board
(marked ➀).
• Continue by fitting the paper low sensor.
Paper Low Sensor
• Remove the three #T20 Torx screws holding the large crescentshaped guide plate that surrounds the paper supply unit. Remove
the guide plate.
• Fit the sensor under the code disc of the upper supply unit using
the same method as with the ribbon low sensor.
• Connect the cable to connector P-602 at the top of the CPU board
(marked ➁).
• Fit back the guide plate and the left-hand cover.
Note!
The ribbon unwind unit and the paper
supply unit are shown dismounted in
the drawing only to improve visibility.
In reality, the only part that requires
dismounting is the guide plate.
