Sharp DHCP settings

[bilyahn]

I normally avoid this problem by setting the IP address to a static number.

When I setup for print with DHCP the unit obtains the address and setup is prompt with no issues. A period of time will go by and we get a call that they can't print. DHCP has changed the imagers settings to a new number. Setting it back solves the issue. Is there some setting that needs to be changed on Sharps to prevent this from happening? All network settings are Sharp default out of the factory.

Thank you very much for your time and effort in this matter. It has been an annoying matter for Sharps. Don't know if it is for other copiers or not but would like some input if you have it.

DHCP

Are you scanning too?? Why not just set the printer to a static the ip is set in the drivers port so it will always be there on the server or the pc no matter if the PC changes.

What you need to do with DHCP is set what is called a 'Static Reservation' on your DHCP server. This is relatively easy to do on a Windows server and a little more complicated to do on a modem / router.

Print a config page out of your machine so that you have the MAC address of the copier as you will need to know what this when making the reservation.

On a Windows server, go to Administrative Tools then DHCP. Expand the fields until you find Reservations and then right click on Reservations and click New Reservation.

You will be required to put a name and description (which don't effect anything) as well as the desired IP address that you want for the copier to use everytime and the MAC address. Once this is all done, reboot you copier and away you go.

You copier will no longer change it's IP address with DHCP enabled.

Thank you. I don't have admin rights on one of the networks that I am working with but I will let their IT people know and will definitely use this in the future!

Can't you print to the host name of the printer rather than the IP address ? I've never actually tried it but don't know why it wouldn't work.

[bilyahn]

Thank you for the idea. How would I set it up to print to the host name? Would that be in the print driver port settings? Would I still have the problem if the IP address doesn't match?

I was hoping that there was something I was missing. Printer's don't seem to have these problems with varying IP addresses, just the copiers.

Do other brands of copiers have the same issues?

Thank you for your response!!

I normally do set it to a static address but was hoping there was something that I could do during setup so an enduser could take the machine and just set it up like a printer without having to call us when their DHCP settings change.

Thank you for the response.

make sure you set static ip for this machine, because if this photo use DHCP it wil be change ip during this running, so i think first you should identifine exactly one ip for this and doesn't any equiment in your LAN take this ip , that easy way for you setup printing for each pc

[bilyahn]

Thank you to everyone who has commented on this. Seems that the static IP address is the only way to ensure trouble free printing.

Do the other copier brands have the same issues? I work primarily on Sharps for network printing so am curious??

Thank you all!

All copiers and computers work in the same fasion and is dependant on the network.

I once worked on a network where the DHCP leases expired once every 2 years. All the PC's and printers / copiers would keep the same IP address for 2 years and then they would be renewed.

I prefer to leave DHCP running on copiers and make the static reservation so that if another tech goes out on site and has to blow away the NIC settings, the NIC will pretty much get all the information back through DHCP. Saves alot of time and stuffing around.

To TheOwl

Good stuff (answer). Thank you.

Success

Out of curiosity, I installed our KM-4050 on our showroom floor to print to the hostname of the printer. If you go to the web page you can get the hostname of the MFP. Then click install printer, create your TCP/IP port using the host name rather than the IP address. This way, it doesn't matter what the IP address of the MFP is. Should work like TheOwl says in case you need to reset the print board or anything like that.

We always get this problem in the office with our Sharp MX2640N, I can fix it temporarily but most of time same error, I tried using ethernet cable directly to the printer and putting a Static IP on the MFP, but still sometimes when we print, computer and printer don't communicate. What is the best way to fix this issue today>?

When connecting direct to the copier from the laptop, having the copier ip fixed will not help as the laptop will probably be on dhcp, there will be no dhcp server so the laptop will get an apipa address. which may not work. (also make sure its a crossover cable)

[mansart]

Crossover cables are not essential any longer most new nic cards will accommodate for a direct connect between laptop and MFP
