Description
Also called “Assembly K spittoon”
The ink service module holds waste ink from the black print cartridge.
When the ink service module is almost full, the printer will not print.
If you do not have a new ink service module available, you can remove the black cartridge to continue printing – the product can print using only the tri-color cartridge, but the color results and print speed are affected.
According to HP’s partsurfer information, this module fits all revisions of the OfficeJet 150 – CN550A and CN550E. The earlier CN550A pre-2013 revisions can also use CN551-67031.
It appears possible that you might be able to flush-out with warm water the existing ink service module, then dry it, refit it and issue a reset following the instructions on http://support.hp.com/us-en/document/c01463304 (this is only a suggestion – MindMachine Associates accept no responsibility for any damages resulting from reusing an old ink service module)
