Questions about this item

How is the YINGHUA ink pump spring installed in the XP-615, and which step is commonly missed?

The spring sits inside the ink pump assembly; the step often missed is aligning the spring ends with the pump housing slots before securing the cover.

What maintenance or replacement will the ink pump spring for the XP-850 need later?
