Dear Canon Support,
I am formally requesting escalation regarding my Canon TR4720 printer, which continues to fail after repeated standard troubleshooting. This printer was installed on a Mac Mini.
I have already performed multiple printhead cleanings, deep cleaning cycles, and printhead alignments, yet the print quality remains consistently unacceptable. The output is defective, with missing content, faded areas, and irregular printing that clearly indicates a hardware or internal ink system issue.
This is no longer a basic configuration problem. I have exhausted the recommended user-level corrective steps, and the printer is still not functioning properly. I am therefore requesting a warranty review, repair, or replacement option as appropriate.
I have attached sample prints that show the defect. Please confirm the next steps and advise what documentation you require to process this claim.
Sincerely,
