2.2.2 Sensors on the MTP-2283
MTP-2283: Accessing the Paper Present Sensor
The MTP-2283 Paper Present Sensor is located under the print head mechanism and therefore the print head
must be raised to access this sensor. The MTP-
2283‟s print head is raised by first lightly lifting the cutter release
latch on the center top of the printer to let the cutter mechanism pivot downward (left picture). Next, gently flex
back the two spring clips on each side of the print head until the clips just clear the spring pins (middle picture).
Finally, once both spring clips are free from the clip pins, rotate the print head up (right picture).
MTP-2283 Paper Present Sensor
The MTP-2283 Paper Present Sensor is located below
the rectangular cutout under the print head mechanism
as shown. This sensor detects if paper is present in the
print head mechanism. If there is no paper presently in
the printer, and paper is fed through the entry slot, the
printer will perform an auto feed operation. If paper is in
the printer mechanism and the paper supply runs out,
the printer will indicate an out of paper status. This
sensor can be cleaned by blowing pressurized air over
the sensor face through the Rectangular cutout in the
chassis.
MTP-2283 Paper Low Sensor
The Paper Low Sensor, shown here, is mounted on the
paper roll holder. It detects when the paper roll is almost
depleted. Printer status feedback will indicate whether or not
the sensor detects the roll as the roll‟s diameter decreases
with use. The sensor surface can be cleaned by blowing
pressurized air over the sensor face through the hole in the
roll side of the chassis.
