How do you re-assemble the rear and of a canon 24-70 f/2.8?

The error code E00807-0001 on a Canon imageRUNNER Advance C5235 indicates a problem with the fixing assembly, which is responsible for fusing the toner onto the paper. Here are some steps you can try to troubleshoot and resolve the issue:

1. Power Cycle: Turn off the printer using the main power switch, which is usually located on the side or rear of the machine. Wait for a few minutes, then turn the power back on. This can sometimes clear temporary errors.
2. Check for Paper Jams: Open the printer's front cover and check for any paper jams or obstructions in the paper path, especially around the fixing assembly area. If you find any paper jams, carefully remove the paper following the manufacturer's instructions.
3. Inspect the Fixing Assembly: The fixing assembly is located inside the printer, typically behind the front cover or access panel. Check for any visible signs of damage, such as broken parts or loose connections. Ensure that the fixing unit is properly seated and securely in place.
4. Reset the Fixing Assembly: If there are no visible issues with the fixing assembly, try resetting it. Open the front cover and locate the green handle or lever associated with the fixing assembly. Move it back and forth a few times to ensure it is properly engaged.
5. Contact Canon Support: If the error persists after attempting the above steps, it is recommended to contact Canon's customer support or a qualified technician for further assistance. They will have access to specific troubleshooting steps and can provide guidance based on their knowledge of the Canon imageRUNNER Advance C5235 model.

When contacting support, be sure to provide them with the specific error code and a description of the issue you're experiencing. This will help them in diagnosing the problem more accurately and providing appropriate solutions.
Please note that the error codes and troubleshooting steps may vary depending on the specific model and configuration of your Canon imageRUNNER Advance C5235 printer. Always consult the printer's user manual or contact Canon's customer support for model-specific instructions and recommendations.

E197 Error Codes caused by electrical noise.
DETAILS:
The error code E197-0000 (laser scanner motor communication error) may be indicated during the wait state upon power-on. Cause: The tube protecting the crimp terminal on the end of the bias cable that is connected to the transfer guide in the rear side of the Registration - Transfer Assembly [1] moves downward, and the uncovered metal portion of the terminal comes into contact with the screw [2]. This causes electrical noise, leading to E197-0000.

This is usually a corona wire problem. There are three corona wire units in the copier. You probably need new corona wires strung, or units. You may get lucky though and just have a hung transfer/separation corona wire cleaner. This is visible if you slide out the transport unit by opening the front door and releasing the green handle, then sliding the drawer assembly out. Look for the unit with the 3 thin, hair thickness wires running front to rear in the silver cavity located just to the right of the black rubber wide transport belts. The unit will have a white plastic "bridge" on it. Look to see if there is an assembly that has cleaner pads on it stuck somewhere along the wires. If it is, be careful and slide the assembly all the way to the front of the corona unit. If there is a problem though, the next time it cleans the wires it will get stuck again. You will probably have to contact an authorized Canon dealer for repairs and parts. This model is very old now, and discontinued/obsolete. Getting parts may be an issue.

Laser polygon mirror motor is in the laser assembly. Take off front and left cover on copier and remove laser gently out of left side.

Laser scanner motor is behind the reader rear cover.

Hello,The rotary switch that you refer to is not available from Kodak.It is mainly sold as the complete rear housing assembly which is the rear half of the camera.You may contact me at [email protected]
I currently have several of these assemblies available if you have someone that can change it.Hope this helps.
Best Regards,Russell

There are two possible problems:
1. A part that holds the feed roller which normally breaks in the Canon iP1800 series
2. The spring that guides one of the gears at the rear of the cartridge parking position is loose.
This is the usual problem I had with my canon printers, I had 80 printers in the past two years.
If you can dare to dis-assemble your printer, I might be able to guide you through it.

6A00 means the cleaning assembly on the right where the printhead parks is jammed. Either a paper scrap or the squeegees jammed into the capping assembly. Cleaning dried ink with a wet Q-tip and pushing the squeegee back toward the rear off of the caps may help, but most times you need to replace the purge assembly, best done at a shop.
