Instructions
2.1 Unpacking and Inspection
Carefully unpack and inspect your printer for any damage that may have occurred in transit. Should
any damage have occurred, notify Telpar, Inc., save the shipping carton and packing materials, and
file a damage claim with the carrier. Specify the nature and the extent of the damage. Before
installing or operating the printer, check the following:
Printer mechanism and paper path are clear of all packing materials or other foreign
matter.
Paper is installed. DO NOT OPERATE the printer without paper. Refer to Section 2.3 -
Paper Loading for paper loading instructions.
2.2 Printer Sensors
The MTP series of printers use infrared, reflective sensors to detect when the paper roll is getting
low, when paper is present under the print head, and when paper has entered the document
presenter (if your printer has the document presenter option). These sensors should be periodically
cleaned from dust and other debris which will accumulate on them over time. Cleaning periodically
will help prevent intermittent, false triggering of the sensors which result in system downtime. It is
recommended that pressurized air be used to clean the sensor surfaces as shown below.
2.2.1 Sensors on the MTP-2822, MTP-2832, and the MTP-2242
MTP-2822, MTP-2832, and MTP-
2242 External Sensor Option
The External Paper Low Sensor
option, shown here, can be
physically rotated to detect various
diameter sizes via a rounded
cutout in the chassis. 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
rounded slot in the
chassis as shown above.
MTP-2822, MTP-2832, and MTP-2242 Internal Sensor
The fixed, Internal Paper Low Sensor, shown here, comes standard
on these printers, and 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 round hole in the chassis. Internal
OR
External Paper Low Sensor detection can be selected via the state of
DIP Switch, position 6 on the printer‟s circuit board (Section 4).
