Advise on HP4 Error 40

The past few days I've been experiencing an Error 40 a number of times with my HP4. I'm using it with a Mac via Ethernet. I've read the troubleshooting section that describes the problem (listed below) and am able to continue printing after selecting "continue" on the printer, but I'm curious why all of a sudden I've been getting so many of these errors?

The statement about the MIO card has me wondering if that's the problem, but I'm not sure where that card is located so I can see if it's seated correctly.

Any suggestions anyone?

Error 40 Data Transfer Error
* Printer and computer may be set to different baud rates.
* The computer is turned off.
* The MIO card is defective or improperly seated.
* Press continue or go on the printer to clear message.

Just when I was beginning to think the troubleshooting page wasn't working. The MIO card is where the ethernet plugs into the printer. You say it's a 4, but I suspect it's a 4M if you're using it with a Mac. There are 2 screws holding the card in. Turn the power off and try and reseat it. I've got a couple of good used tested ones in stock if you have a bad one.

Actually the HP4 I've got is the basic one -- I added the Postscript module and AppleTalk (not Ethernet) to it myself. Attached to the AppleTalk port on the HP4 is the Farallon EtherWave adapter which allows me to ue the printer on my network.

I'll try as you suggested and reseat the AppleTalk card, but is IS strange that these errors came up out of the blue and I have not moved my printer in months.

For curiosities sake, what is the cost of the Ethernet cards that you have?

I can let you have the Apple Talk card for $50. The combo Jetdirect card with ethernet, appletalk and twisted pair is $125.

I've reseated the AppleTalk card and will see how that works first.
