Disassembly and Assembly canon copier
Be sure to observe the following when disassembling or assembling the machine:
1.
Disconnect the power plug of the host machine before starting the work.
2. Unless otherwise noted, assemble the machine by reversing the steps used to disassemble
it.
3. Identify the screws by type (length, diameter) and location.
4. Some mounting screws are equipped with a toothed washer to protect against static electricity.
Be sure to use each washer.
5. As a rule, do not operate the machine while any of its parts are removed.
6.
If the deck is equipped with a drier heater, be sure to disconnect the power plug of
the heater before starting the work.

Start-Up Sequence canon image runner
The CPU on the main controller PCB is programmed to read the system software from the
hard disk and write it to the SDRAM mounted to the DIMM socket on the main controller
PCB. (For this reason, it will be a while before the control panel becomes ready after the
main power switch is turned on.
The control panel shows the following screen while the CPU writes the system software
to the SDRAM, and the progress of the start-up sequence is indicated by means of a bar on
the screen.
