Troubleshooting guide

3-2 System Operation
Once a file is sent from the computer, the CPU stores this file in its memory until either a new
file is sent (printed) to it, the system gets re-homed which clears it’s memory, or the system is
powered OFF. Located on the CPU are standard, computer memory SIMM(s) (30 pin, non-
parity, 70 ns) that store the print file as long as the system remains powered ON. Once the laser
system receives a print file, that particular file can be repeated as many times as desired.
Once the “START” button is pressed the CPU starts the Motion System movement which places
the Focus Carriage (part of the motion system that contains the Focus Lens) above the
designated engraving or cutting area. The CPU then sends signals to the Laser Cartridge to
precisely control the firing of the laser beam with the movement of the motion system. Once the
file is complete, the Focus Carriage will go “home” to the upper right corner.
The laser system is shipped with a standard 4 MB SIMM. Although it is unlikely that a single file
can exceed the memory capacity, it is possible if the file fills the entire engraving area, has a
large amount of fine detail, and engraved at the highest resolution of 1000 DPI. The system can
also run out of memory if the entire engraving area is engraved using the “3D” effects in the
Printer Driver. If necessary, additional memory can be purchased from your Dealer or directly
from our Customer Support Department.
The programming code that operates the CPU Module is called the “Firmware”. At some point
in time, ULS may update the Firmware code due to product enhancements, software
compatibility, bug fixes, etc. Firmware updates are available through your dealer or directly from
our Customer Support Department’s web-based email system at (www.ulsinc.com
).
5) Control Panel
This is where the operator controls the laser
system.
START: Providing that there is a file in
memory, pressing the START button will begin
laser processing from the beginning of the file. After the file has completed processing,
pressing START again will process the file again from the beginning. You can repeat the file as
many times as you wish providing you do not send a new file nor power the system OFF.
STOP: Will halt the engraving or cutting process. If you sent a new file while the system was
running the previous file, pressing STOP will not only halt the engraving or cutting process, but
it will also clear the existing file from memory and allow the new file to take it’s place.
NOTE
We suggest that you do not “Print” another file while one is processing. If you do, your
computer will respond, “There is an error printing to LPT?. The Printer is not ready. Make sure it
is turned on and online. Select Retry or Cancel”. If you select Retry, you will keep getting this
message until the laser system completes it’s file in memory or you press the Stop button.
DOWN: Will move the Z-axis table down .01 inch. If you press and hold the button, the Z-axis
table will continue to move slowly in .01 inch increments until it has moved ½ inch and then it
will automatically increase speed until you release the button and start the process over again.
