hp 4250 duplexer installation
I have several 4250's networked in my office. I recently purchased a used duplexer and hoped that the installation would be easy. I inserted it in the back of one of the printers and then configured the printer screen to "duplexer on" and also configured the printer properties on my PC to "duplexer on". However, this doesn't seem to work. I think that I haven't yet "installed" the duplexer correctly. Do I have to go to the main server and configure the driver there? (which I don't know how to do!)
Thanks for help,
Ken

4200 and 4250 duplex units look identical but they dont work that way. Are you getting an error when you install or is it not seeing it completely.
LJ4250 and adding a duplexer
Folks,
People seem to think that adding a duplexer to a 4250 is like adding a duplexer to an older LaserJet.
It is not.
The duplexer is NOT AN ACCESSORY for the 4250/4350 and a whole slew of others. You have to BUY a duplex enabled printer.
As I tried to explain before, the printer's firmware has a "switch" in it. This "switch" is either "DUPLEX ENABLED" or "DUPLEX DISABLED". This "switch" is set at the factory, during assembly. That's why I said, unless your printer has a "D" on the nameplate, you are not going to be able to enable duplex on the printer.
With older printers, the LaserJet 4, 5, 4000, 4100, 5000, 5100, just adding a duplexer gave you the ability to duplex. It is no longer that way with printers manufactured the last 2-3 years.
Also, most duplex enabled printers MUST have a set amount of RAM. A base 4250 wouldn't have the amount of RAM to duplex. You would have to add more memory. But that still doesn't help you if the duplex "switch" in firmware hasn't been activated.
Sorry about the bad news.

Any 4200/4300/4250/4350 can use a duplex unit. I rebuild these and neither of my test printers have a d after the model number. I rebuild about 15 a week of the two types, which is the main problem. The only two ways I've found in telling them apart is:
#1
A= 4200/4300 unit has R73-5053, RU5-8086 part numbers on the unit
B= 4250/4350 unit has R73-5047, RL1-4088 part numbers on the unit
#2
Test unit in 4250 - if it recognizes it without errors its type B. If it fails test in 4200/4300
Test unit in 4200 - if it works, it is type A. If not, it is either defective, the connector to power supply is bad, or power supply is bad.
I never had a formatter that needs more memory, but then I use the same printers all the time and they have extra memory. It is a posibility and I dont claim to know everything about them as I'm still learning.
