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

2011 Telpar, Inc. (Rev.20110809) Page 15

printer, the printer will enter the Factory Burn-In Mode. Fifty shorter sheets will be printed.

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.

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.

4.2.2 Descriptions of Commands

4.2.2.1 Status commands

All transmission of status in IEEE-1284 mode is disabled at power on. Status transmission must be
enabled by the US S +n command before any STATUS transmission will occur in IEEE-1284 mode.

In case of an ERROR as defined in the table below, the printer transmits DLE E and the 2 status bytes.
The response to a STATUS REQUEST is to transmit DLE (10hex) followed a SOURCE byte that
distinguishes what type of status is being transmitted followed by the two status bytes as defined in the
table below.

The SOURCE byte is defined as:
A = Auto Status Back. Is disabled by default but is enabled when the printer receives the DLE A +n1

+n2 command. +n1 and +n2 define a mask using the same byte/bit structure as in the table below.
A "1" in a bit position enables the automatic transmission of DLE A and the 2 status bytes when an
enabled condition occurs. The bit positions marked as errors in the table will always cause the
automatic transmission of DLE E and the 2 status bytes so these positions will usually be "0" in the
user defined mask.

B = Buffered status. DLE B and the 2 status bytes are transmitted when the DLE B command is

processed out of the input buffer.

R = Real Time Status. If enabled by US R +n command, DLE R and the 2 status bytes are transmitted

immediately when the DLE R command is received by the printer.

U = not a true STATUS request. When DLE U +n1 +n2 is processed out of the receive buffer, the

printer transmits DLE U +n1 +n2 back to the host. The user can send DLE U +n1 +n2 anywhere
within a document if he needs to know that the printer has processed the document up to that
point.

4.2.2.5 Bit Image (BI) Graphics Mode Commands
BI US * +nH +nL +data 1F 2A +nH +nL +data

256*nH +nL defines how many bytes of bit image data will follow. The data is received sequentially with
the first byte representing the first 8 dot positions at the top left side of the bit image with bit 7 being to
the left and bit 0 being to the right as printed.

XMOVE US x +nH +nL 1F 78 +nH +nL
The horizontal print position is set to (256*nH + nL) * 8 dots from the left margin.
If there is a lot of white space on the current dot line, the XMOVE command can cause the print

location pointer to be moved resulting in less data required to define a dot line of bit image data to be
printed. Anytime there is more than 4 bytes of white space (32 dots) the XMOVE command will result
in less data being sent to the printer. Another BI command can follow the XMOVE command until a
YMOVE signifies the end of the current dot line.

YMOVE US y +nH +nL 1F 79 +nH +nL
Causes paper to feed 256*nH + nL dot lines. This is also the BI line terminator and print command.

4.2.2.6 Print Bar Code Command
GS k +m +n +d1dn [1D 6B +m +n (DATA)]

+m selects the bar code type. +n defines the number of data bytes which follow.
If more data is sent than can fit on the printer being used, the bar code is not printed.

4.2.2.7 Bar Code 128 definitions

Code128 Character set: 103 data chars, three different start characters, and a unique stop character.
CodeA consists of the ASCII characters 00hex thru 5Fhex, FNC1 thru FNC4, Shift, CodeB, and CodeC.
CodeB consists of the ASCII characters 00hex thru 7Fhex, FNC1 thru FNC4, Shift, CodeA, and CodeC.
CodeC consists of 2 digit numeral characters 00dec thru 99dec, FNC1, CodeA, and CodeB.

The 103 different bar code patterns have different meanings depending on whether CodeA, CodeB, or
CodeC was specified when the data was received. The data string must start with {A or {B or {C to specify CodeA,
CodeB, or CodeC. A checksum is calculated and printed by the printer.

6 Troubleshooting

6.1 General Troubleshooting

Printer does not seem to do anything  Check the following:

 Printer is plugged into an active power source with the correct voltage and current ratings
 Power supply – Is it active or switched to the „ON‟ position (if applicable)?
 Is the main circuit board getting power? Check the Red 5 Volt Power LED (See Section 6.2

below). If the 5 Volt Power LED is not lit, and an approved external power supply that is known

to be working correctly is being used, then the main circuit board on the printer has probably

failed. Call Telpar Technical support for assistance.

 Is the printer‟s print head or Head Up lever in its fully closed position? These printers will not

attempt to print unless the print-head is fully and securely closed.

 Is the main circuit board‟s DIPSWITCH, position 1 switch in the “Up” or ON position? If so, slide

the switch to the OFF position and cycle printer power. The printer will not print with this switch

on (flash memory upload mode).

Printer feeds paper and performs a Self Test but does not print from the host (computer, controller,

etc.) Check the following:

 Communications Cable – is the correct type of cable being used, and is it securely connected?
 Is the correct printer driver installed on the host (if required)?
 Is the printer connected to the same port that was selected when installing the printer driver?
 Is the host‟s printer port „Ready‟ or „OFFLINE‟? Is there a conflict with another printer on that

port?

Printer’s Document Presenter, Cutter and/or Paper Low Status not working as expected /
General unexpected printer operation / Unexpected Printer Error check the following:

 Are the printer‟s DIP Switch‟s on the main circuit board correctly set for your application?

Remember, whenever any DIPSWITCH positions are changed, the power to the printer must be

cycled for the change to take effect.

 Is the printer‟s print head or Head Up lever in its fully closed position? These printers will not

attempt to print unless the print-head is fully and securely closed.

 Printer is plugged into an active power source with the correct voltage and current ratings.
 Sensors are clean (free of paper dust or other unwanted obstructions). Clean sensors by

blowing pressurized air over the sensor face.

Printer presents a blank document (nothing is printed on the ticket) or the printing is too light 
check the following:

 In case of a blank document: verify that the roll of paper is Thermal Paper (not plain paper) and

that the paper is fed into the printer with the thermal side up (this is the most common cause for

receiving a blank document as only one side of a roll of thermal paper is printable typically).

 In the case of the print appearing too light: check the setting of the darkness control adjustment

(R35 on the Main Circuit Board – Print Density). Try rotating the adjustment clockwise to darken

the print. 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 –

this will help extend the life of the print head element.

LED 2 provides PAPER_LOW and PAPER_OUT

status.

 Blinking indicates Paper Low Status.
 ON indicates Paper Out Status.

LED 3 & 4 Provide error status (see table below)

characters)  check the following:

 The default factory settings for the MTP Series serial protocol is printers is 15,200 bps (baud

rate), 8 Data Bits, 1 Stop Bit, No Parity. The Host controller (computer, PLC, etc.) must be set to

the same settings as the printer in order for the printer to print correctly.

Paper jams in Printer or Presenter  check for the following: (ALWAYS KEEP FINGERS AND TOOLS

AWAYS FROM CUTTER BLADES!)

 Obstructions in the paper path (including the paper presenter loop if a presenter is used – it is

very important that the paper loop that forms below the presenter section does not physically
contact anything)

 Misalignment of the paper path. This is possible if the printer‟s original paper roll holder is not

being used, but rather a different design has been implemented that allows the paper roll to
be located away from or outside of the printer. If this is the case, you must make sure your
design maintains a reliably aligned paper path from the paper roll location to the printer.

 Is Incorrect or out-of-spec paper is being used? Paper that is not to the paper specifications

for your printer increases the chances of having repetitive paper jams.

 An Inoperable document cutter or damaged cutter blades not fully opening or closing.

 Is the Customer allowed to pull the exiting document before the printer is done printing or

cutting? This is a common jam scenario. To avoid this possibility, specify the document
presenter option by added to your printer when ordering.

Printer suddenly stops and does not respond unless the power switch is cycled  check the
following: (ALWAYS KEEP FINGERS AND TOOLS AWAYS FROM CUTTER BLADES!)

 Is there a paper jam condition? Are cutter blades not fully open (if applicable)?
 Check the Diagnostic / Error LEDs and use the table below to interpret the problem the printer is

reporting. See if the problem can be corrected based on the printer‟s diagnostic feedback.

 Possible dirty or defective paper sensors or Print-head Latch Switch. In the case of dirty sensors

obstructed by dust or paper fragments, clean sensors by blowing pressurized air over the sensor

face.

Certain ERROR codes are reported when they occur by a sequence of blinks of LEDs 3 and 4 located on the
controller board. The ERROR BLINK patterns are listed below. This table is also printed during a self test.

LED 3 blinks ON four times indicated in the table below as T1, T2, T3, and T4. Following each sequence of blinks
there is a pause before repeating the sequence. The ON times of LED 3 is the time base used for encoding the
error reporting by LED 4. LED 4 blinks ON during some of the four times that LED 3 blinks ON. The pattern of ON
times of LED 4 listed in the table below indicates the ERROR being reported. The printer‟s audio beeper will also
sound a long tone at the same time LED 4 is ON.
