To use the C823632A Type-B Ethernet card with the AC Adapter set the power select switch located on the board of
the interface card to position "A" as shown below in Figure 1. For more details refer to the Getting Started section of
the Administrator's Manual that is included with the Ethernet card.
Figure 1.
Other Possible Workaround(s):
1. Disabling Photo Accelerator
Disable the Photo Printing Accelerator option in the driver - This will result in slower print speeds. To compensate
for the loss of print speed and to keep the engine running close to full speed should be used with faster CPUs
(500Mhz or higher) with at least 512Mb of memory.
2. Setting C823632A Ethernet Card to 10Mbps
Connect the printer to a 10Mbps Hub if available, or if using an Autoswitching 10/100Mbps hub change the dip
switch settings on the Ethernet card to restrict the communication speed to 10Mbps / Half Duplex. Decrease in print
performance should be minimum. To do this follow the procedure below.
a. Power the Printer Off.
b. Wait for lights on Ethernet card to go out.
c. Disconnect AC Cable from printer.
d. Undo the thumbscrews and remove the card.
e. Locate the dipswitches and set Sw 1-1 & 1-2 to the UP position (position towards center of card). The
default for all 4 switches is down.
f. Reinsert the Ethernet card and plug in AC cable to the printer.
g. Power the printer back on and wait for Ethernet card to synchronize with the network (bottom green light
on the Ethernet card will be solid).
h. At this point you should be able to communicate and printer via the Ethernet card. The card will now be
running at 10Mbps / Half Duplex and decrease in print performance should be minimal.
3. IEEE 1394
For optimum print speeds The IEEE 1394 (C823722) option card is recommended by EPSON. This card is only
supported under the following operating systems: Windows 2000, Windows Me and MAC OS 9.1
