Google "color lj4700 memory". I saw 512MB for $27.00

Evening eavotri, -The first thing to do is pull out the EIO card and all of the added memory. -Restart the printer and listen for the fan to come on and see if there are any changes in the boot process. If it boots then starting with the memory reinsert one of the modules and reboot. Repeat the process till you find the culprit. You may find that after reinserting everything its still working. You may have lucked out and just had an EIO card or memory module that had a bad contact or you may have an intermittent fault that will reappear again. If nothing has changed can you give me more details about what you observed or heard during the boot process: - Does the fan come on shortly after you power on? - What displays during the boot process besides the memory check? -You mentioned the last thing you saw; does that mean the LED went blank? Let us know what you find out and don?t forget to rate the posting.
