this link is going to take you the manuel that what you have to do when you got an error.

Error 08 relates to the main motor having problems turning. Quite often this is caused by a faulty consumable (opc,toner or transfer belt). Could also be that the lid is not closing properly and stopping the toner carousel turning freely.

This error (12H) pertains to the Laser Unit of the printer which is damaged and needs to be replaced. The Laser Unit is the heart of the printer, it's what transmits the image to be printed. You need to contact a service center and will run you about $200. I had this same problem with my printer and had to call Technical Support and they gave me the bad news

Fatal error code 2AH: Faulty memory data.

1 - Unplug the power cord and plug it in, then turn OFF and ON the Power Switch.

It relates to the transfer belt unit, replace it

Rack rotation failure, I'm not 100% that this is that error, but does the rack, where the toner are move ? if not, move it with manually a little bit then restart printer.

You need to clean the printer. See your manual for instructions. It is probably dust on the laser lens
