TIPS TO USE HIGH-SPEED ECP PARALLEL COMMUNICATION
•
If the parallel port setting on the printer is set to
BI CENTRO
(See Menu Mode
Operation – Menu Structure Overview) your printer is ready for high-speed bi-
directional communication.
•
In order to be able to use this high-speed mode without problems please note:
•
Computer Bios for parallel port should be set to ECP
•
Only use a shielded and balanced parallel cable, which is IEEE 1284 compliant.
•
If your RIP software is protected with a hardware lock (dongle), which needs to be
placed on the parallel port, it is best to have available 2 parallel ports.
–
One port to connect: hardware lock, scanner, external drive or CD-ROM,…
–
One port (ECP) directly connected to the printer.
In case either of the above mentioned topics is not respected you may encounter all kinds
of printer artifacts such as: unexplainable error messages, sheet-off during printing,
unexpected media feed during printing, etc…
If this occurs, switch your system to unidirectional parallel communication.
–
Set print parallel port to Mode > CENTRO
–
Set computer parallel port Bios to SPP or EPP
The data transfer will then slow down and the artifacts will disappear. Before switching
back to the high-speed bi-directional parallel mode, have your computer system examined
closely by a trained computer technician.
