Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
As to the error code you mention:
That is agreed commonly to mean a defective printhead. Printheads can overheat and short out, with excessive (or with heavy usage in hot environments.)
As to clearing the error: on the iPF750, holding down both the Navigate and the Load buttons cleared the error in one case.
If this answers your question, please rate my answer. Thanks.
I have no information to indicate that the printheads are separable, as opposed to all-one-printhead, on this model. So as far as replacement goes, it's the whole printhead that needs replacing.
Going into service mode... I was busy researching data from multiple sources for you, so I forgot that aspect: In service mode, follow the most reliable source or guide you have, and don't touch anything else but what you are trying to get done. If you change any setting or value, note down what change you made where and from what previous value - that can be very essential, since some settings in service mode can disable a printer quite distinctly if done wrongly.
So proceed with care, and follow the best source for directions.
If this answers your question, please rate my answer. Thanks, ***** ***** luck.
I looked for such information. No info from the error code said anything about which printhead it might be, just 'the printhead'.
If your source is reliable and says it's just one of the printheads, per that error code, then it should be a good indicator, I think.
Service mode isn't that intelligent. It will not tell you anything (comprehensible.)
Quoting your original post:
My research says that it is a burnt out right printhead.
I would like to comment that I don't know how you determined that. Which color was having a problem, before? and what was the problem?
I can offer you a second opinion on this case, by Opting Out, which opens the case to other Experts in this category.
Good luck with it.
