Question about HP LaserJet 4730 MFP Printer
A 59.51 error would normally indicate a problem with the cyan drum drive motor DC controller. First of all I would recommend resetting the printer and unplugging it from the wall for a minute or so while it is off. Sadly if this doesn't clear the error any further fixes would involve cold resets, disconnecting and replacing components.
In which case it would probably be best to call an engineer unless your feeling particularly brave.

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.

that dotted line is produced by one of you toner cartridges,put attention to what color the dots are and replace the cartridge.
also there is an option in the menu to disable the cartridge check ,do that under "diagnostics menu" and start taking 3 cartridges the first time and print something,check if dots are present,if not put another cartridge print something and check ,repeat process until you find the defective one.
