How the imagePASS operates

When a customer prints, the motherboard and printer interface board process image data. The printer interface board is a custom
board and allows the imagePASS to communicate with the printer. The CPU, which is located on the motherboard, controls the
transfer of image data to and from the motherboard and runs the interpreter. DIMMs, which are also located on the motherboard,
hold image data during printing.
The interpreter rasterizes the page description file and compresses the image pattern into memory using compression technology.
The interpreter outputs the compressed raster data through the image frame buffer memory to the printer interface board. The
raster data is sent to the printer, which then renders the image on paper at maximum speed.

Preparing for hardware installation or parts replacement

Before installing or servicing the imagePASS, follow general precautions and obtain the correct tools.
It is strongly recommended that before you service the imagePASS, you carefully read all precautions and notices (see
"Precautions" on page 3).
Also, keep in mind that the most common cause of a hardware problem is a faulty or loose connection. Before you replace an
expensive component, check internal and external connections

Precautions

This section includes information about how to safely operate and service the imagePASS and how to avoid damage to
imagePASS components.
Report shipping damage
If there is evidence of shipping damage, save the shipping boxes and damaged parts. Call the shipper immediately to file a claim
and notify your authorized service/support center.
Do not change an existing network
The imagePASS is probably connected to an existing Local Area Network (LAN) based on Ethernet hardware. The network is
the link between the customer's computer, existing laser printers, and other prepress equipment. Never disturb the LAN by
breaking or making a network connection, altering termination, installing or removing networking hardware or software, or shutting
down networked devices without the knowledge and express permission of the site administrator.
Do not assign an IP address to the imagePASS
Only the site administrator should assign an IP address to a network device, including the imagePASS. If you enter an incorrect
IP address for the imagePASS, errors may occur on connected devices.
