Epson Ethernet Communications - IP Address Problem?
Professor Hooligan
I'm screwing up on protocol here!
QUESTION: On a simple home ethernet network (Mac, cable modem, and Epson
1520 printer, tied together with a FriendlyNet FH308 hub), what TCP/IP
settings should the printer use? (IP address, subnet mask, and auto IP
address on/off)?
BACKGROUND: I've been using this printer with the Ethernet card
(C823572), attached directly to my computer with a crossover cable, for
two years without a problem. I need now to add a cable modem to my
little network, so I bought an ethernet hub. To make a long story short,
I can get all three devices (computer, cable modem, and printer) working
simultaneously if I do everything just right, but if I turn off the
printer, it won't come back onto the ethernet. It just sits there with
the alternately-flashing lights, like it's hooked to nothing.
THE LONG STORY: The only way I can get the printer working again is to
connect it directly to the Mac again using the crossover cable. Then I
reboot printer and Mac and everything works. Without powering anything
down, I then disconnect the printer from the crossover cable and connect
it to the hub with a regular cable. I then connect the Mac to the hub
using a regular cable. The cable modem is already hooked up to the hub.
At this point, everything works perfectly as long as the printer is not
turned off.
After that, the lights on the card alternately flash, as if it's hooked
to nothing.
The Epson Ethernet card thinks it's at 11.22.33.44 with a subnet mask of
255.255.255.0. I think my Mac is at 24.178.207.236, and the cable modem
is at 24.178.207.1 with a subnet mask of 255.255.255.0. I've tried
putting the printer at 24.187.207.2 with mask 255.255.255.0 and auto ip
<off>. Made no difference in behaviors - had to use the "long story"
method to get the printer onto the network again.
I tried to find a tutorial on IP addressing before I posted, but
couldn't find anything at the right level of detail for me. Epson tech
support told me the cable was too long... (I resisted the temptation to
point out to them that the cable works fine BEFORE the printer is
rebooted.)
Thanks for your help folks... If you need to know anything about
hydraulics I can reciprocate ;-)
