Chapter 1: The 7156 Printer 7156 Setup and User’s Guide
The industry-standard RS-232C communication interface allows the 7156 to b e
connected to any host computer that uses RS-232C. Control codes are provided for
easy migration of applications written for Epson as well as other NCR printers.
With thermal printing technology on the more frequently used receipt station,
there is no ribbon cassette to change and paper loading is extremely simple.
Printing on single- or multiple-part forms, validating checks, and printing checks
is also easy in the accommodating slip station. An additional option is the
Magnetic Ink Character Recognition (MICR) check reader with parsing which
reads account numbers on checks for easy verification. An extended slip table is
available for handling large forms and is standard with the MICR check reader
option.

7156 Setup and User’s Guide Chapter 2: Setting Up and Using the Printer
Choosing a Location
The 7156 printer takes up relatively little counter space and may be set on or near
the host computer. Make sure there is enough room to open the receipt cover to
change the paper and to open the front cover to change the ribbon cassette. The
illustration shows the actual dimensions of the printer, but leave several inches
around the printer for connecting and accessing the cables.
Note: The optional Magnetic Ink Character Recognition (MICR) check reader
feature has been factory adjusted for a normal operating environment with a host
computer. However, additional devices, such as CRT monitors, or large metal
surfaces that are near the printer can affect the printer’s magnetic field, causing
intermittent reading errors when the MICR check reader is in operation.
This condition can be easily diagnosed by checking the MICR check reader and
adjusting it if the factory setting has been altered by your operating environment.
See the Owner’s Guide for more information.

Connecting the Cables
There are three different types of cables that connect to the printer:
Power supply cable supplying power from the power supply
Communication cable connecting the printer to the host computer
Cash drawer cables connecting the printe r to one or two cash drawers
Caution: Disconnect the power before connecting the cables. Always connect the
communication cable and cash drawer cables before connecting power to the
power supply. Always disconnect power to the power supply before disonnecting
the communication and cash drawer cables.
Follow these steps to connect the cables. See the illustration on the facing page.
1. Unplug the power supply from its power source.
2. Connect the power and communication cables to their respective connectors
under the printer as shown in the illustration.
Be sure to screw the communication cable to the c onnector on the printer.
3. Route the cables through the cable clamps on the bottom of the printer, then
through the two slots in the cable access cover as shown in the illustration.
Note: The strain relief bushings are shipped in the box and help secure the
cables. The cable clamps may be shipped in the box or may be attached or
molded to the bottom of the printer. Use the cable clamps or strain relief
bushings, or both, to keep the cables from being unplugged which may
damage the connectors or interrupt a transaction.
4. Connect the communication cable to the appropriate host c omputer connector.
5. Connect the cash drawer cables to the pr inter and cash drawers.
The connectors are standard phone jac ks located at the rear of the printer.
6. Plug the power cord into the power supply, then plug the power supply into
an outlet.
At this point, the printer receives power. If the On Line LED (green) is on, the
printer is on-line. Otherwise, the printer is off-line.

Loading and Changing the Receipt Paper
Although the illustrations show a used roll being removed, the instructions apply
to loading paper for the first time.
Change the paper when either of the following two conditions occurs:
Paper Status LED (red) flashes: the paper is low
There are approximately 1 ½ to 7 ½ meters (5-25 feet) of paper remaining on
the roll. Change the paper as soon as possible to avoid running out par t way
through a transaction.
Depending on the application program, the host computer may alert you when
the paper is low.
Paper Status LED (red) turns on: the paper is out
Change the paper immediately or data may be lost.
Caution: Do not operate the printer or host computer if the printer runs out of
paper. The printer will not operate without paper, but it may continue to accept
data from the host computer. Because the printer cannot print any transactions, the
data may be lost.

Printing on Forms or Checks
There are several types of transactions that require you to insert a form or check
into the printer:
Credit card transaction (some credit card transactions may be printed on the
receipt station and not require any forms)
Multiple-part forms such as credit transactions or merchandise returns
Electronic funds transfers
Check printing (printing the date, payee, and amount on the check face)
Check endorsement
Although the illustration on the facing page shows a check being inserted into the
printer, the instructions apply to any type of form. The 7156 can print on forms up
to five-parts thick. See “Ordering Forms” later in this book for more information
about the type of forms that can be used.
1. Insert the form or check (check shown in the illustration) from the front and
place it on the slip table top first and with the print side up.
If the form is extra long, you may need to insert it from the side.
2. Slide the form or check to the right until it lines up against the guide (wall).
If the form is extra long, you may need to slide it over the form stop to
disengage it. In this case, you will need to mark the slip table for lining up the
form for the proper placement of the print on the form.
3. Slide the form or check toward the back of the printer until it contacts the form
stop (it won't be able to go any further);
Or, align the form or check with any preset mark you may have made on the
slip table for custom forms.
The green LED on the slip table turns on when the form or check is properly
inserted (the form has to cover two sensors on the slip table).
4. Follow the instructions from the host computer.
The printer begins printing.
5. Remove the form or check after it has been fed back out.
6. Follow the instructions from the host computer to finish the transaction.

Cleaning the Printer
There is no customer maintenance required for the 7156 printer. However, you
may occasionally clean the cabinet as needed to remove dust and finger marks.
Use any household cleaner designed for plastics, but test it first on a small unseen
area. The cabinet materials and finish are durable and are resistant to the following
items:
Cleaning solutions
Lubricants
Fuels
Cooking oils
Ultraviolet light
If the receipt paper bucket is dirty, wipe it with a clean, damp cloth.
Caution: Do not spray or try to clean the thermal printhead or the inside of the
printer with any kind of cleaner as this may damage the thermal printhead and the
electronics.
If the printhead appears dirty, wipe it with cotton swabs and rubbing alcohol. If
spotty or light printing problems persist after cleaning the thermal printhead,
contact your NCR authorized service organization.
Note: The thermal printhead does not normally require cleaning if the
recommended paper grades are used. If non-recommended paper has been used
for an extended period of time, cleaning the printhead with cotton swabs and
rubbing alcohol will not be of much benefit. See “Chapter 3: Ordering Paper and
Supplies” for recommended paper.
