Note: The NOTE format highlights important messages and additional information.
How the E-46A 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 E-46A to communicate with the printer. The CPU controls the transfer of image data
to and from the motherboard and runs the PostScript interpreter. DIMM holds 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.
Before you service the E-46A
Before you service the E-46A, it is strongly recommended that you make sure that you have the required tools (see
“Tools you will need” on page 11) and carefully review all precautions (see “Precautions” on page 12).
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 (see page 50).
