For the error code "7a" to be fixed permanently, you need to ensure that the main PCB is fine and is working in good condition.
If the error code is caused due to malfunctioning of the main motor, then you need to check the whole setup by connecting it with another motor.
In this case, make sure that there is no mechanical load present on the main board.
While fixing this error code, you will notice that the motor runs slowly initially and then picks up the speed later.

Hi Erika:

A burning smell presents when paper is stuck on the fuser (The hot thing that heats the toner to the paper.) I would take out the drum, and peek in the printer with a flash light and see if you see any paper stuck anywhere it does not belong. Usually, the paper will be burnt "Brownish" in color.

With the drum, there are contacts on them. Make sure they are clean; and do not have toner residue on them. Easy to clean with a pencil eraser. Gently, rub the eraser over the metal contacts to clean off residue. Hope that helps you. If so, please leave me positive feed back.

This can sometimes be related to paper dust interfering with a sensor. A burst of canned air can fix the problem. Just pull out the toner, open all of the covers and spray air into all the little crevices. You might want to do this outside, in case toner is loose in ther, so as not to make a mess.

My machine displays on the LCD: "machine error 68"


First, I would recommend NOT trying to manually install this printer by using the add printer wizard in windows and selecting the the port and drivers to use. I would use the install cd to set this all up, it makes setting up this printer MUCH easier. If you are unable to use the install cd then get the IP address for the printer from your router admin page then with the printer "installed" go into the printer properties, go into the port, add a port, and instead of using a printer name just type the IP address for the printer in. Also for any networked printer make sure you don't have a firewall blocking it (this would include making sure that if the printer requires a port opened in the router that all requests for that port are routed to the IP address of the printer).
