of the Main cable as shown and lower it into the recess on the underside of the
printer.

USING THE PRINTER
Inserting a Paper Roll
Note: Be sure to use paper rolls that meet the specifications listed within this guide. Do
not use paper rolls that have the paper glued to the core as the printer cannot detect the
paper end correctly.
1. Ensure the printer is not receiving data; otherwise, data may be lost.
2. Open the paper roll lid by pressing the lid release button. If the button will not
open the lid, see the Troubleshooting section in this guide.
3. Remove and discard any partial paper roll or empty core.
4. Insert the paper roll as shown. When the paper roll is in place, ensure the paper
feeds from the bottom of the roll.
5. Before closing the lid, pull out a small amount of paper, then close the lid by
pressing on both sides of the lid (simultaneously) or press on the middle area of the
lid (near the paper exit). The lid is closed once you hear a “Click”.
6. Tear off any excess paper. QP1 is now ready to print.

Receipt cutting
For your convenience, the QP1 Printer has an auto cutter that will cut the receipt
automatically after printing. A small portion of the paper is left uncut, gently pull the
receipt and the paper will break away.
If the auto cutter fails, a secondary tear bar is included as a backup. Simply pull the
receipt toward you to tear off.

towards the front of the printer.

Enclosure cleaning
Note: All cleaning should be done when the power supply is off.
Do not spray water or any liquid directly onto QP1. Any liquid that goes into the product
may cause a failure, fire, or electric shock. Turn off QP1, then gently wipe the outside
surfaces with a micro-fiber cloth dampened with a small amount of water. Do not use
flammable liquids (benzene, thinners, etc.) or a cleaning agent.
Print head cleaning
Cleaning should be done when any one of the following conditions occurs:
•Reduced printing quality
•Unusual noise whilst feeding paper
Do not touch the surface of the printer head with bare hands. Do not use hard tools on
the printer head, rubber platen, and heating element, as this may cause damage.
Do not use organic solvents to clean the printer head, such as gasoline, acetone, etc.
Cleaning steps:
•Turn off the power supply
•Cleaning should be done after the printer head has completely cooled.
•Wipe the heating element of the print head lightly with cotton swabs with
ethyl-alcohol applied.
•Ensure all cleaning solution has completely dried before printing.
Paper Feed Roller cleaning
Cleaning should be done when any one the following conditions occurs:
•Paper has stopped feeding
•Paper feeding is unusually noisy
Cleaning steps:
•Turn off the power supply
•Wipe the Feed roller clean with a lint free cloth with ethyl-alcohol applied
•Ensure all cleaning solution has completely dried before printing.

Self-Test
The ‘Self-Test’ lets you know if your printer is operating properly. This test is independent
of the QT720 Payment Terminal, and independent of all software.
Running the Test:
1. Make sure a suitable paper roll is installed and printer lid is closed properly.
2. Hold down the FEED button until the self-test begins. The ‘Self-Test’ will print a
test pattern. The printed pattern should have good contrast and be consistent in
appearance. If the test print is poor, see the Troubleshooting section in this
guide.
3. The printer is ready to receive data as soon as it completes the ‘Self-Test’.
Storage
Do not store the printer in damp places or areas with large temperature variations.
Condensation on the printer may cause damage to the thermal head or unit failure.
Do not store the printer in dusty places.
When storing the printer for longer than six months, the printer lid must be kept open
such that the Paper Feed roller is not in contact with the Thermal Print head. If the Paper
Feed roller and Print head have continued direct contact for prolonged periods the Feed
roller can become deformed and may affect normal operation.
