When to change the receipt paper

Change the paper when it is near the end of the roll or when the roll is empty. When the paper is low, you
must monitor usage to avoid running out part of the way through a transaction. When the roll is empty, you
must load a new roll immediately or data may be lost.

● When the paper is low, a colored stripe appears on the receipt paper (if the paper purchased has a stripe)

indicating that enough paper remains for a small transaction.

● When the roll is empty, a green LED on the printer ashes quickly indicating the paper must be installed.

IMPORTANT: Do not try to operate the printer or host computer if the printer runs out of paper. The

printer may continue to accept data from the host computer even though it is unable to print. Data may
be lost as a result.

Loading the printer receipt paper

1. Open the receipt cover by pushing up evenly on each side of the cover until it unsnaps (1).

2. Remove the test printout or used paper roll if necessary.

3. Place the receipt paper into the paper compartment on the spindle so that it unrolls from the inside (2).

Leave a few inches of paper sticking out of the printer. To prevent jamming, make sure the paper is
between the guidelines.

4. While holding the paper in place, close the receipt cover (3) making sure to apply a little more pressure

after the rst click to ensure that it is fully latched. When fully latched with paper installed, the LED will
stop blinking.

When to change the receipt paper 45

5. To test that the paper is loaded correctly, advance the paper with the paper feed button (1), and then

tear the excess paper o against the knife on the cover. A steady green LED (2) means the printer is on
and operating normally. If the LED is ashing, the cover may not be completely shut.

Thermal paper specications

The printer requires qualied thermal paper with the following dimensions:

● Width: 80 +0/-0.6 mm (3.15 +0/-0.03")

● Diameter: 50.8 mm max. (2”)

The paper must not be attached at the roll’s core. Use paper with a colored stripe at the end to indicate that
the paper is running low.

The above gures are based on a core diameter of 22 ± 0.5 mm (0.87") outside and 11.5 ± 0.5 mm (0.45")
inside.

Qualied paper grades

Contact the manufacturer of your choice to order paper. HP recommends the following paper grades
produced by their respective manufacturers. There are a number of paper manufacturers qualied to provide

B Electrostatic discharge

A discharge of static electricity from a nger or other conductor may damage system boards or other static­sensitive devices. This type of damage may reduce the life expectancy of the device.

Preventing electrostatic damage

To prevent electrostatic damage, observe the following precautions:

● Avoid hand contact by transporting and storing products in static-safe containers.

● Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

● Place parts on a grounded surface before removing them from their containers.

● Avoid touching pins, leads, or circuitry.

● Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods

There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:

● Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist

straps are exible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground cords. To
provide proper ground, wear the strap snug against the skin.

● Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet when

standing on conductive oors or dissipating oor mats.

● Use conductive eld service tools.

● Use a portable eld service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, contact an HP authorized dealer,
reseller, or service provider.

NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or service

provider.

C Computer operating guidelines, routine

care, and shipping preparation

Computer operating guidelines and routine care

Follow the guidelines below to properly set up and care for the computer:

● HP recommends a 17 mm clearance around the vents on the computer head unit and I/O connectivity

base for heat dissipation.

● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.

● Never operate the computer with any access panels removed.

● Do not stack computers on top of each other or place computers so near each other that they are subject

to each other’s recirculated or preheated air.

● If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be

provided on the enclosure, and the same operating guidelines listed above will still apply.

● Keep liquids away from the computer and I/O connectivity base.

● Never cover the vents on the computer or I/O connectivity base with any type of material.

● Install or enable power management functions of the operating system or other software, including

sleep states.

● Turn o the computer before you do either of the following:

● Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products may

discolor or damage the nish.

● Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign
matter can block the vents and limit the airow.

NOTE: For more information on your retail system care and maintenance, refer to “Retail Point of Sales

Systems - Routine Care and Maintenance” available at http://www.hp.com/support.

Touch screen maintenance

Keep your display and touch sensor clean. The touch sensor requires very little maintenance. HP recommends
that you periodically clean the glass touch sensor surface. Be sure to turn o your display before cleaning.
Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning agent for your touch
sensor. It is important to avoid using any caustic chemicals on the touch sensor. Do not use any vinegar­based solutions.

Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths. Always dampen the cloth and then
clean the sensor. Be sure to spray the cleaning liquid onto the cloth, not the sensor, so that drips do not seep
inside the display or stain the bezel.

54 Appendix C Computer operating guidelines, routine care, and shipping preparation

MSR maintenance

To clean the MSR (magnetic strip reader), swipe a standard cleaning card through the MSR a couple of times.
You can order a standard cleaning card online. You can also put a thin oil-free cloth around a credit card.

Shipping preparation

Follow these suggestions when preparing to ship the computer:

1. Back up the hard drive les. Be sure that the backup media is not exposed to electrical or magnetic

impulses while stored or in transit.

NOTE: The hard drive locks automatically when the system power is turned o.

2. Remove and store all removable media.

3. Turn o the computer and external devices.

4. Disconnect the power cord from the AC outlet, and then from the computer.

5. Disconnect the system components and external devices from their power sources, and then from the

computer.

6. Pack the system components and external devices in their original packing boxes or similar packaging

with suicient packing material to protect them.
