1.6 Power Supply Requirements
1.6.1 External Power Supply (supplied separately)
Use a Listed/Certified Power Supply.
Follow local wiring codes for external wiring.
1.6.2 Voltage : 24 VDC ±5%
No requirement for external 5 VDC power supply, the 5 VDC for logic is supplied from the 24 VDC, by a regulator
internal to the printer.
This printer prints using high speed currents at a low duty cycle. Typically, a switching power supply rated at 24 Volts
DC. 2 Amps is all that is needed as long as the power supply does not have too much over current protection.

Specific to Thermal Printers: TELPAR does not warranty damages to the thermal print head as a result of printing
with thermal paper not specified or approved by TELPAR
2 Operator Instructions
2.1 Unpacking and Inspection
Carefully unpack and inspect your MTP-2200 for any damage that may have occurred in transit. Should any damage
have occurred, notify TELPAR, 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 2.2 - Paper Loading for paper
loading instructions.
2.2 Paper Loading
2.2.1 Side-Loading Roll
The MTP-2222 printer is configured as a side-loading printer . Slide roll of paper over spindle with paper fed off the
bottom toward the paper slot (front of unit).
To load paper , turn on the power and feed the straight edge of the paper into the paper guide. Inserting paper will
result in the automatic loading of paper once it is fed into the paper guide
Ensure that the paper is installed correctly and feeding properly with the thermal side facing up.
2.2.2 Top Loading Roll
The MTP-2232 and MTP-2242 printers are configured as a drop in loader . Load the roll of paper by placing the
spindle inside the roll of paper and place spindle in slots with paper fed off the bottom toward the paper slot (front of
unit).
To load paper , turn on the power and feed the straight edge of the paper into the paper guide. Inserting paper will
result in the automatic loading of paper once it is fed into the paper guide.
Ensure that the paper is installed correctly and feeding properly with the thermal side facing up.
2.3 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 . Caution should be exercised when working next to the cutter mechanism , the
blades are sharp and may cause serious injury.
To release paper:
·Move Head Up lever to right of Advance wheel to top position
·Lift cutter mechanism to “Open position (See - MTP-2242 with Cutter Mechanism open ) Paper can be
removed at this time. Once paper is cleared from the mechanism, return the cutter assembly to its home position.
Models MTP-2222 , MTP-2232 and MTP-2242 all operated similarly
·Move Head Up lever to right of Advance wheel to the bottom position to return to printing position
2.3.1 Head Up Lever
The Head Up lever is located by the Paper Feed knob . The down position is ready to print. The middle position
reduces pressure between the printhead and the print platen roller for easier manual feeding. The up position lifts the
printhead 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.

3 Installation
3.1 Self Test Mode (also Burn-in and Hex Dump modes)
The MTP-2200 series has a self-test mode that will print and cut a sample document. All electrical and mechanical
portions of the printer are exercised and checked by this action, except for the serial interface or parallel interface
components. The self-test printout also shows pertinent information pertaining to operation of the printer.
3.1.1 Self Test
To place the unit into self-test mode : turn the power switch off, press and hold the FEED push button switch and place
the POWER switch in the ON position, then release the paper feed switch. See Figure 4 - MTP-2242 Self Test
Printout for examples of the self-test printout.
3.1.2 Factory Burn-in Mode
If the paper feed button is held for 4 seconds after power is turned on, the printer will enter the Factory Burn-In Mode.
A hundred shorter sheets will be printed.

Page 12 of 52
3.1.3 Hex Dump printing mode
If the paper feed button is held for 8-12 seconds after power is turned on, the printer will enter the Hex Dump Mode.
All codes received will be printed in HEX format rather than causing the normal execution, this may be useful for
troubleshooting applications.
3.1.4 Continuous Factory Burn-in Mode
If the paper feed button is held for 12 seconds after power is turned on, the printer will enter the CONTINUOUS
Factory Burn-In Mode that does not stop after 100 sheets are printed.
