I will explain you the cause for it.
It prints in yellow first and then override with black for better quality. This is the reason your color ink gets empty.
Have a great day!

I have a HP Business Inkjet 1220 Printer, and the block ink cartridge light is flashing. I replaced the cartridge with a brand new one, closed the door, and black ink light is still flashing. I put in another neew black ink cartridge, closed the door, and same issue- black cartidge ink light flashing. I cannot print- what to do?

SOURCE: HP L7680 Print Head Problem
Sometimes the circuit strip that sits at the back of the printhead carriage is the problem due to moisture, ink soiling, etc...
To clean these you need some cotton buds (like you use to clean your ears) and gently clean the area at the back of the printhead carriage (where the printheads slot into).
This removes any ink, or moisture that could be causing a short circuit or similar.

There is some confusion here. You say "ink sponge needs replacing" in an Epson C86 (although you have your query posted under HP Officejet 5610!) - I presume you mean the waste ink pads. If so, you need to dismantle the printer - the pads are not under the print head but deep inside the case. I can provide all the information you need to complete this task if you really want to do it yourself. Please post a new comment requesting this assistance if you do.

Possibly you printer has two ink tanks ? a small black one and a large one ? If one is empty it will not print black. The better solution is to use a q-tip and some alcohol to clean the head. If the cartridges have been replaced - possibly the new one is defective? U might also try using the head clean option in the printer properties. Additionally sometimes the contacts for the cartridge are dirty or if they have been touched with fingers they will not work, alcohol again is recommended to clean those.
