Color Imageclass MF644cdw Not Found on Mac using Wireless Connection

I have owned this printer for about one year.   I set it up and it was working but every time I try to print using the wireless Lan option, the printer can not be found.  I usally figure it out but to be honest, in the year I have owned this printer, it has not worked most of the time.   A week ago I downloaded the new drivers and I was able to print.  Now once again the printer cannot be found.    I have reconnected to my wifi and I have downloaded the drivers again.  

 

Please help.   

 

Many thanks,

Greetings,

Most common cause of this behavior.

 

IP address of printer is changing.  Printer does not have the IP your MAC thinks it has the last time it was used, or the name cannot be resolved using bonjour or WSD.

 

Assign a static IP to the printer.  Two ways to do this.

 

Printer;

Assign an IP, subnet mask and gateway.    Result, printer always has the same IP (devices can always find it at this destination)  Doesn't matter if you use it once a day, week, year, etc.  Always gets the same IP.

or 

 

Router:

Reserver IP Address based on printer's wireless adapters MAC address.  Result (Same) printer always has the same IP (devices can always find it at this destination) 

 

You'll need to consult your routers documentation.

 

This only has to be done once.

Rick,

 

Thank you so much for your reply and helpful instructions.   

 

I successfully assigned a static IP to the printer via the printer and I was able to print and scan.

 

Many thanks, 

 

Kathy

 

ps.   The test will be if I can print in another two weeks!

Hi Rick,

 

My printer worked just fine until but now it is not.  The message in the Printer Que is Printing - Looking for printer but it can't seem to be found.

 

Is this the same issue or do I have another problem.

 

Kathy
