2 Self Test

2.1 Self Test Preparation

The PAM 3000 Label Printer has a built-in self test, which makes troubleshooting easier and gives information
about the configuration of the device.
In order to make a self test printout please load material (labels, continuous paper) which covers the entire
printing width.
If you wish to make a test printout in thermal transfer mode, use transfer ribbon of maximum width.

NOTICE !
The test printout is made regardless of label gaps, and is about 230 mm long.
Continuous media would be best suited for test prints, otherwise, a normal sheet of
paper which is cut to a width of 115 mm can be used in thermal transfer mode, too.

Before starting the self test the DIP-switch 3 located in the opening at the right side of the printer has to set on

OFF (see Operators Manual). The self test is initiated by either pressing the key when switching on the
printer and keep them pressed until the system test is completed. The display will show Testprint. You may start

the self test by pressing the pre-dispense key at the front side of the printer. Test printout can be aborted by

pressing the key.

3 Internal Setup

3.1 General Information

In addition to the setup facilities that can be accessed by the user (see Operating Manual), the printer has an
internal setup which is to be used by service personnel only.

In order to use the internal setup you need a terminal application. Therefore you can use Windows-Terminal
on a Windows-PC, ZTERM on a Macintosh, connect on an ATARI or KERMIT under UNIX.

This example describes the use of the Windows Terminal application.
It is recommended to remove the machine out of the production line while using the Internal Setup.

3.2 Starting the Internal Setup

For preparation, set the parameter "Interface" in the user setup of the printer to specify RS-232, baud rate 9600.
Now start the Windows terminal program on the PC.
Select "Transfer" from the menu "Preferences" and adjust the terminal program to the printer setup (baud rate
etc.).

Now start the user setup of the printer again by using one of the following options :

1. Hold the keys

-key.

3) Reset counters

There are two sets of counters, each containing three counters which track:

working time
transfer printing total length
thermal printing total length

The first counter set reflects the totals over the lifetime of the printer.
The second counter set is intended to show totals for the interval since last technical service. Having
completed the maintenance work, you can reset this second set of counters as follows:
After keying a 3, the following prompt will display on your monitor:

Mode ?

Enter the password CARRY to reset the service counter and the result of the system test (test printout,
status display) to 0000.

The test result can be reset also without resetting the service counter. To achieve this, use the password
RESLT.

4) Save as default values

By selecting option 4 you can specify as defaults the parameters you have set up using operator setup.
This will store your current values for the following as defaults:

- country

- transfer print

- label edge sensor

- interface

- cut position

- peel position

- heat level

- character set

- brightness

Save defaults ? (Y/..)

Generally, you will only need to save new setup parameters as defaults when components have been
replaced (e.g. printhead), the tolerances of which differ from those of the old components.

5) Adjust label gap sensor

Use option 5 to adjust the label gap sensor. This will be necessary when the label gap sensor itself or the
CPU PCB have been replaced. Once initiated, follow the prompts, removing and reinserting label stock, as
