Grease coming in new printheads for better contact between printhead and carriage contacts

HP Recommended

I would like to know what kind of grease HP uses in printheads to apparently improving contact between printhead contacts and carriage contacts.

Anyone knows?

You need to clean that greasy film.

Which plotter do you have? None of the normal consumer/small business models with replaceable heads would have any grease unless HP has changed something recently. Due to the density of contacts, any type of conductive grease would be a sure cause of shorts in the printhead due to overlap.

If HP wouldn´t think it useful, I don´t think they would put it in the first place...

That greasy film is for contact protection, not for better contact.
