• HP 3755 Printer, Black Ink Mystery

    Printer is an HP DeskJet 3755. It uses a tri-color cartridge, and a
    black cartridge. It's connected to various Windows computers via a
    Netgear router. Connection is fine.

    The black cartridge is empty, as demonstrated by the fact that when
    printing a 'Test page', all that is printed is the blue printer icon, and
    also in blue, the words "Windows Printer Test Page".

    When printing any multi-color document, all colors are printed, but
    nothing black, such as text, appears. OK, it's out of black, but...

    If I use the printer's control panel to print out internal reports such
    as "Printer Information Page", or "Printer Status Report", which are in
    black text, these reports are printed perfectly in black.

    How is this possible?

    Hmmm...print jobs issued from Windows don't print black, but print jobs
    issued internally from the printer's control panel do print black.

    I downloaded and ran HP's Print and Scan Doctor for Windows. It said it corrected a printer issue (it didn't identify the issue), and then went
    on to check ink and printing quality, such as alignment and cleaning printheads. The result was that colors were fine, alignment was fine,
    but it didn't print out any black patterns, saying that the black
    cartridge was empty.

    So, HP's own diagnostic verified black ink was empty.

    But where does the black ink come from to print the internal reports, perfectly?

    Any ideas?

    If the black cartridge is empty then the only way that the printer can print black is to use the colour cartridges. That is probably what is happening. The printer is probably designed to combine the colours to print black for internal
    reports.

    Tony, you may have been correct. I finally got around to getting a new
    black cartridge (the printer is 3 hours away from where I normally
    reside, thus the long time to reply). Once installed, the printers is
    working beautifully. It prints black (and all colors) perfectly.
    Thanks for the reply.
