Question about Lexmark T640 Laser Printer

Network connections to Lexmark T640 Laser Printer

Just purchased a Lexmark T640 for my computer lab in a high school. Problems have arisen from the beginning. My previous HP 420 series was a work horse and networked easily. This printer will disconnect from our network on a regular basis. If more than one student is printing at the same time, instead of stacking up in memory, at least one of them will get an error message that they cannot print due to printer setup problems. Other times they CAN print! It is as though only one can print at a time and have to "time it" so that this error doesn't show up. Can anyone help me?

Might try going into the printer setup on each computer and set it to print after the current job is finished. Let me know :-)

Why will my T632 not print over Wi-Fi from my 2011 iMac (10.7.4)?


If the Lexmark T632 is already connected through the Ethernet, it will not be possible to connect it through wireless. The printer cannot be configured with both the Ethernet and the wireless function enabled. The printer will choose the physical connection (Ethernet / LAN) over the wireless connection.

Can I make a "non-network"


With a USB print server like this one, you can hook your printer to one of the wired ports on your router and it can be accessed by any connected computer. (There are other sources and adapter styles; I just picked this one as a sample. I've installed several of these and it works well.)

You can also share a printer on the network by installing it on a computer as a network printer and enabling printer sharing on that computer. But then that computer will need to be left on all the time for others to access the printer, and if people frequently use the printer it will slow down the computer for whoever is using it.

Please, go through the printer's menus and make sure that the Ethernet port is activated.

Lexmark T640 LCD display went blank


Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
