Without doing a complete disassemble, remove all covers, remove paper tray(s), remove ink cartridges (or laser cartridges...everything that is EASY to remove. Clean your rollers (may be gummed up a bit), remove all dust, dirt, grime, everything. My Canon printers are extremely sensitive to jams. As long as you keep it clean internally, you should have no problems. Take a look at this video about paper jams.
Do a hard reset of printer to see if that clears up the electronics memory and restores operation. If that procedure and reinstallation of software does not remedy situation then something is wrong with the printer.
Get the latest drivers from:
Canon SENSYS LBP2900
Make sure all cables are correctly attached. If via network, then check connections at the network switch or router.
Try connecting directly by USB cable.
Here are a few things you can try,
Unplug and replug the USB cable. (I'm sure you tried this.. Lol.)
Try another USB slot on your computer.
Restart your computer and try it again.
If the USB cable can detach from the printer, check if it's loose.
Find the printer software on the Internet and download it there instead.
If those things to solve the problem, consider that the printer may just be broken..
this printer has a usb interface can you see an axis 1650 usb to ethernet server box attached to the usb cable that is attached to the printer ?
would check power to the usb to ethernet server box see photo inserted of what it looks like !
Maybe the power has been disconnected or the ac-dc adapter has gone faulty .
If it has power may be try removing power from it for 20 seconds and then re plug in and then test by printing to printer.
check print server has valid ip address.
also check dhcp server on network has not got printer servers ip address in its lease range. check also that printer server's ip address is static and not being set automatically.
if printer server is ip address try going to dos prompt on p.c. and type in ping {ip address of server} eg c:> ping 192.168.0.2
press Enter key

Can you guys please describe it more precisely please?i have the same issue right now but i don't understand which SENSOR are you guys talking about..the white large one,the switch sensor ,one in the middle or the two BLACK CLAW TYPE SENSORS ATTACHED TO THE HEATING SECTION?OR PHOTO WILL WORK MORE.
After changing the Toner take a Test print from the printer (not from the Computer) this can be done by a Combination of key button or single key button on the printer if you can obtain the test print correctly then connect the printer to the computer .
Turn off the printer,wait 10 minutes,than turn it on. If not good yet,open the top of the printer.Look for small shooter that holds the laser.Open,and force the laser out into the center of tracking craddle.After you move the laser,unplug the printer for few minutes.Then plug it back in.
Your printer motor is getting a run signal from somewhere in the print process. Does it stop when you turn off the power with the switch? Does it stop if there is no paper in the tray or, if the paper tray is removed? Most importantly, do you have schematics and can you do multilayer board soldering? If not, just replace the mainboard.
