Not sure about a "workaround" per se?
If you google the U052 error code you will find many "fix it" related links probably including this one:
https://support.usa.canon.com/kb/index?page=content&id=ART138026
If none of the link fixes work then you may have other recourse including a class action suite. You can, within given requirements, receive an award towards replacing or repairing the printhead.
Here is the link for that:

Note: For the record I have a MX870 - fortunately no problems to date. Did get notified about the class action suite and options. I do not qualify to make a claim.
