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.

External Paper Low Sensor detection can be selected via the state of

DIP Switch, position 6 on the printer‟s circuit board (Section 4).

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.

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.

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).

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.

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.

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-to­time. 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

3 Manual Operation and General Operational Tests

3.1 Paper Cut and Paper Feed Buttons

The MTP series of printers have two external, momentary push-buttons that allow the operator to
manually feed and cut paper. The locations of these buttons are shown below. When the Feed
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
