The hardware error code indicates that a print head failure has been detected. Other possible causes of this error are a faulty cable connection to either one of the PCB's.First try replacing the Print Heads and if the problem persist, re-seat the cabling to the Relay PCB and the Carriage Unit PCB. Since you are unable to access service mode, you will need to ignore the normal print head replacement procedure and replace the printheads whilst the plotter is turned off.The plotter will need to be disassembled to access the print head.See the following service manual for a detailed guide:http://mail.davin.be:8888/CANON/BOOK%20IPF/IPF750/ipf750_755-sm.pdf
