Hi Harden, Thats an issue with the fuser assembly,try to check the teflon condition/ teeth gear might have worn out.

Bad Transmission is a fault coming from your JetDirect network card.
Try reseating it. (With the power off!)
You could also try swapping it to the EIO 2 Slot. On the back of the device
(Again, with the power off!)
Comms errors will dramatically slow your printing, and can fill the memory with garbage.

Performing a cold reset 1 Print a configuration page to record the previous printer settings. 2 Turn the printer off. 3 Hold down GO while turning the printer on. Release GO after COLD RESET appears on the printer control panel display. COLD RESET (in English) appears on the display for one second to verify that the key sequence has been recognized, followed by the power-on self-test message. Once the power-on self-test is finished, the message RESTORING FACTORY SETTINGS displays in English.

Yes, but it IS important to use good quality toner.

If you've never done this before, be aware that toner is a VERY fine powder, and will go straight through a normal vacuum cleaner filter, and if you do this in the kitchen, 'the wife/fella' (delete as apprpriate) will probably kill you ('cos unless you're careful it will go everywhere)!

the sensor was jammed so that even though there was no paper in the output tray the printer believed the tray was full. Fixing the jam didn't reset the printer, however, so it was necessary to reboot the printer.

If the error is '20.00 Insufficient Memory'
No action required. It is simply out of memory because the file you printed was too big.
If you keep getting the message, simpify the print job and/or add more memory to the device.

You could also..
Change the setting in the <Configuration Menu>, <Clearable Warnings>, from 'On', to "Job'.
This will get rid of the message a bit quicker.

I cannnnoooooottt believe what I am reading! If you are going to use labels on a laserjet, you need to get thermal labels! The other cheap labels are made for inkjets, matric, or daisywheel printers. The laserjets have heat rollers that will melt plastic. It will melt the gum on the non thermal labels and get them everywhere!!
Master Rod

Sensor is located on the door lower center of door ther should be a small brush next to it
