Specific to Thermal Printers: Telpar, Inc. does not warranty damages to the thermal print head as
a result of printing with thermal paper not specified or approved by Telpar, Inc.
1.5 Document Presenter Option (Presenter dimensions can be found in Section 5 –Printer Drawings)
The MTP Printer Series can be ordered with an optional document presenter which attaches to the
front of the printer (just after the cutter mechanism). The purpose of the document presenter option
is to prevent a person from making physical contact with a document until the document has been
completely printed and cut. This decreases the likelihood of someone purposely or accidentally
causing a paper jam or smearing the printed information by pulling on the exiting document before it
has finished printing. This option is especially useful when printing long documents.
Preventing human contact with a document during a printing operation is accomplished by allowing
the presenter to hold the leading edge of the document (preventing the document from exiting the
printer) while the remainder of the document is being printed. A paper loop will form below the
presenter assembly while document printing is in progress. Finally, after the completed document is
cut, the presenter ejects the document up to the trailing edge of the paper which it holds so that the
customer may take the document from the presenter exit. The printer can be configured to retract
the document if the customer has not removed it after a specified passage of time.
Check with our sales team to see if a Document Presenter would be beneficial to your application.

2 Operator 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).

MTP-2822, MTP-2832, and MTP-2242 Paper Present Sensor
The Paper Present Sensor, shown here, is part of the print
head mechanism and is located at the front of the
mechanism‟s paper entry slot. 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 paper entry slot.
DOCUMENT PRESENTER OPTION ONLY –MTP-2822, MTP-2832, and MTP-2242
The Presenter Sensor (location shown above) detects when the leading edge of the paper has
entered far enough into the presenter section to stop the presenter motor from turning and thereby
preventing the paper from being ejected until the printer prints and cuts the document. It also detects
if the document has been successfully ejected (or retracted) from the presenter section after the
document has been printed and cut. To access the Presenter Sensor, loosen the presenter‟s top two
mounting screws and pivot the presenter section down as shown above. The Presenter Sensor may
then be cleaned through the rectangular cutout in the chassis.

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.

DOCUMENT PRESENTER OPTION ONLY –MTP-2283
The Presenter Sensor (location shown below) detects when the leading edge of the paper has entered far
enough into the presenter section to stop the presenter motor from turning and thereby preventing the
paper from being ejected until the printer prints and cuts the document. It also detects if the document
has been successfully ejected (or retracted) from the presenter section after the document has been
printed and cut. To access the Presenter Sensor, remove the presenter‟s top paper guide first. To do
this, lightly flex back the spring clip on the side of the presenter until the guide‟s tabs are just fully exposed
(shown below). Then lift and remove the guide from the presenter (right picture).

2.3 Paper Loading
2.3.1 Side-Loading Roll
The MTP-2822 and MTP-2832 printers are configured as side-loading units. Slide the roll of
paper over the spindle so that the paper will feed into the print mechanism from the bottom
of the roll (thermal coated side up).
To load paper, power the printer and feed the straight edge of the paper into the print
mechanism‟s paper in-feed slot. NOTE: The printer does not have an ON / OFF Switch.
Inserting paper will result in the automatic loading of paper once the leading edge of the
paper covers the Paper Present Sensor in the mechanism (Section 2.2.1). Ensure that the
paper is installed correctly and feeding properly with the thermal side facing up.
2.3.2 Top Loading Roll
The MTP-2242 and MTP-2283 printers are configured as a drop in loader (as shown
below). Load the roll of paper by placing the spindle inside the roll of paper and slide the
spindle into the slots. The paper must feed into the print mechanism from the bottom of the
roll (thermal coated side up). To load paper, power the printer and feed the straight edge
of the paper into the paper guide. NOTE: The printer does not have an ON / OFF Switch.
Inserting paper will result in the automatic loading of paper once the leading edge of the
paper covers the Paper Present Sensor in the mechanism (Section 2.2.1). Ensure that the
paper is installed correctly and feeding properly with the thermal side facing up.

2.4 Clearing a Paper Jam
In the event of a paper jam condition do not force paper into the unit, or try to pry the paper out of the
unit, this may damage the thermal print mechanism. Instead, lift the print head up, off the paper to
clear a jam as shown below. Caution should be exercised when working next to the cutter
mechanism, the blades are sharp and may cause serious injury! Therefore, it is recommended
to unplug the Printer before clearing a jam!
2.4.1 Lifting the Print Head and Cutter Sections of the MTP-2822, MTP-2832, and MTP-2242
The MTP-2822, MTP-2832, and MTP-2242‟s Head Up lever is located by the Paper Feed
knob as shown below. Rotating the lever to the fully down position allows the print head to
physically contact the paper while also closing an interlock switch which tells the printer it
is ready to print –you will not be able to print if the lever is up. When the lever is in the
middle position, it reduces pressure between the print head and the print platen roller for
easier manual feeding. In the fully up position, the lever lifts the print head off of the platen
roller for manually inserting paper or for clearing a paper jam. Both the middle and up
positions signal the microprocessor that the head is up so that no printing will occur.
The MTP-2822, MTP-2832 and MTP-2242 have a cutter mechanism that can easily be
rotated up away from the print head to further assist in clearing jams that occur between the
print head and the cutter. However, if the printer has a Document Presenter and a paper
jam exists between the print head and the cutter or between the cutter and the presenter,
the presenter section must be pivoted down and out of the way before the cutter section can
be raised. To do this, loosen the presenter‟s top two mounting screws and pivot the
presenter section down as shown below in the left-hand picture. The cutter section can then
be raised as shown in the right-hand picture.

2.4.2 Lifting the Print Head of the MTP-2283
The MTP-2283‟s print head is lifted via releasing three spring clips as shown below. Lifting
the head will allow you full access for clearing jams in the printing section as well as access
to the Paper Present Sensor which may need to be cleaned from paper dust from time-to-
time. When the print head of the MTP-2283 is in the up position, be careful not to physically
contact the actual print head element itself (element looks like a long, dark stripe on the
bottom of the head) as you may easily damage it. The printer will not be able to print or
automatically feed paper with the head up. When closing the print head, make sure that all
three spring clips are fully secured around their respective spring pins.
If the printer has a Document Presenter and a paper jam exists between the cutter and the
presenter, then the top section of the presenter may be removed to provide easy access to the
jam. To do this, lightly flex back the spring clip on the side of the presenter until the guide‟s tabs
are just fully exposed (shown below in left-hand picture). Then lift and remove the guide from the
presenter (right picture).
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.
Next, gently flex back the two
spring clips on each side of the
print head until the clips just
clear the spring pins as shown
below.
Finally, once both spring clips are
free from the clip pins, rotate the
print head up as shown. A paper
jam in the print head section can
now be easily cleared.
Document Presenter‟s top guide
plate can be easily removed to
allow access to paper jams in the
cutter / presenter section.

Button is pressed, the printer will feed paper until the Feed Button is released. When the Cut Button
is pressed and released, the printer will feed and cut one short section of paper.
3.2 Self Test Mode and Burn-in Mode
The MTP series has a self-test and Burn-in mode that will print and cut sample documents. All
electrical and mechanical portions of the printer are exercised and checked by this action (except for
the communication interface components). The self-test printout also shows pertinent information
pertaining to the current printer setup.
3.2.1 Self Test
NOTE: The printer does not have to be connected to a host (computer, PLC, or other controller) to
perform a Self Test. To place the unit into self-test mode: remove power from the printer, then press
and hold the FEED button (see above). Next, return power to the printer, then release the paper feed
switch after hearing one beep. The printer will print a Self Test form showing pertinent information
pertaining to the current setup and sample text and barcodes.
3.2.2 Factory Burn-in Mode
NOTE: The printer does not have to be connected to a host (computer, PLC, or other controller) to
enter the Factory Burn-in Mode. If the Feed button is held for five beeps after power is applied to the
printer, the printer will enter the Factory Burn-In Mode. Fifty shorter sheets will be printed.

4 Printer Control
4.1 DIP Switch Settings and Print Darkness Adjustment
Note: Both the Printer‟s DIP Switch and Print Darkness Adjustment can be accessed through the cutout in the
metal chassis as shown:
DIP Switch Settings: Each Printer in the MTP series of printers has a DIP Switch located on the main circuit
board (see photo below). The DIP Switch contains a bank of eight individual switches, each of which controls
some aspect of the printer and are described in the table below. The switches can slide up into the “ON” position
or downs into the “OFF” position (the picture below shows switches 1, 2, and 3 in the “OFF” position, and switches
4, 5, 6, 7, and 8 in the “ON” position. A small tip screwdriver or even a pen tip may be used to change the position
of the switches.
The DIP Switch on each type of printer can be accessed through a cutout hole on the metal circuit board cover –
therefore, DIP Switch changes can be made without removing the cover. IMPORTANT NOTE: If you make any
changes to the DIP Switch settings, you must first cycle power to the printer in order for the changes to take place.
Print Darkness Adjustment: Control R35 on the circuit board is the Print Darkness (or Print Density) Control (see
photo below). Clockwise rotation of the control increases print darkness, but also consumes more current and
shortens the life of the print head. Therefore, it is recommended that the darkness level be increased to the point
that just meets the desired darkness level under the normal ambient operating conditions for the printer application.
DIP Switch contains a bank of eight
individual switches with each switch
controlling some functional aspect of
the printer (see table below). Here,
positions 1-3 are shown “OFF” while
4-8 are shown “ON”.
The Print Darkness (Print Density)
adjustment is located below the DIP
Switch as shown. Rotation
clockwise increases the print
darkness, but also draws more
current and decreases the life of the
print head element. It is
recommended that the darkness
level be increased to the point that
just meets the desired darkness
level under the normal ambient
operating conditions for the printer.

TAB will exceed the right margin, an auto-print
is performed and the print position is set to the
start of the next line.
Line feed
LF
0A
Data on the current line is printed, paper is fed
one line based on the current line spacing, and
the print position is set to the left margin. If the
current line spacing is set to less than the
current font height then paper is fed to print the
current font height (see ESC 2, ESC 3 +n, and
ESC C +n).
