Re: Copier Not Initialising properly

Sounds like you have a fuser failure. Check the heater lamp, thermal fuse and thermistor. One is probably bad.

Scanner error 6

most likely dust on the scanner optics causing scanner to be unable to go to home position. Solution would be to disassemble scanner assy and clean optics or replace scanner assembly.Note HP service manual says to replace scanner assy.

A C26 code is a peak detection error on your scanner. You'll have to turn off the copier, remove the glass and CAREFULLY clean the mirrors and exposure lamp on the scanner. That usually takes care of the problem.

LSU ERROR shows in display panel

The LSU is the Laser Scanning Unit or "printhead". There is a mirror in there that spins really fast, if the mirror spins too slowly (bad motor, low voltage) it gives an error. Sounds like you would need a replacement LSU. Have the printer serviced.

Canon np6030 copier

Does the machine start and switch itself off? Some errors cause this to occur to prevent further damage. Try switching it on with the front door open, this will prevent the fixing heater circuitry from initialising. You will then need to find the error code. The ones that cause it to switch off never appear on screen, only viewable thru service mode. Push a straightened paper-clip into the hole below the right hand meter inside the front of the machine, press << and >> to get to *1* DISPLAY, find ERROR and let me know. Hope this helps...
