Identifying the Issue While attempting to print some black and white documents on copy paper, I faced a creased printout with ink smudges along the edges. Soon after, the printer displayed the dreaded 6A00 warning. Upon inspecting the printer, I noticed a piece of paper near the purge pad, likely causing the issue. However, even after its removal, the error persisted.

Troubleshooting Steps Turning to online resources, I discovered that the sled above the purge pads was stuck, hindering its movement. Despite cleaning and using isopropyl alcohol, the sled remained immobile. After applying silicone spray and gentle manipulation, I successfully freed the sled, resolving the error code.

Encountering Loose Plastic During the troubleshooting process, I stumbled upon a loose piece of black plastic near the sled. Despite efforts to reposition it, the plastic seemed disconnected from its original placement, raising concerns about its necessity.

Community Assistance Although uncertain about the plastic's purpose, I sought assistance from online communities. Suggestions included thoroughly cleaning the purge unit with window cleaner every six months and exploring options for acquiring replacement parts from local sources.

Solution Discovery Further exploration revealed a mirror image of the plastic piece inside the print head carriage. Recognizing its probable location, I identified two glue points and devised a plan to stabilize and reattach the plastic using super glue.

Troubleshooting error code 6A00 on the Canon Pro 9000 mk2 involves meticulous inspection and targeted cleaning of the purge unit. While resolving the error, it's crucial to address any loose components and seek community support for comprehensive solutions. By following these steps, you can restore your printer's functionality and ensure consistent print quality.
