  1. The halogen fuser lamp in my HP 4M has apparently bit the dust. (I'll know for
    sure tomorrow when I do a continuity check.)

    I looked for replacements. Most companies won't reveal whether they're selling
    real HP parts, or third-party units (of unknown quality).

    The most-amusing site was the following. I leave it for readers to judge for

    They seem to go out around every 10 years. This is the second time it's
    And an RH7-4048 for 240V.
    The prices are all over the place. A genuine HP runs from $27 to over $60. I
    found non-HP lamps for $4.50 -- but they want $10 for shipping.
    Found several on eBay, from $25 to $40.

    I wasn't aware of the brittleness of the plastic. I'll look closely.
    Fortunately, I have the service manual, which makes things easier.

    Fingerprints on a halogen lamp are a no-no. When I replaced my slide
    projector's lamp, I cleaned it just to be safe.
    Looks mucho useful. Almost everything is on YouTube, isn't it?
    "Unfortunately", the 4- and 5-series LaserJets were made by Canon and are
    classics. Yes, it's slow on graphics, but I don't use it heavily enough to
    justify a new printer. Other than the toner cartridge and fuser lamp, it will
    probably outlive me. What would I buy of the same quality?
  3. junk descriptions like that means the part is a pull from a scrap pile
    from a bank or hospital.

    it's likely to not even work at all.
  4. If they are 'real' HP parts, I'd seriously doubt if they are newly
    manufactured. Re-manufactured, probably.

    I bought a fuser assy. from them a couple of years ago to repair my
    HP LJ III -- with no difficulty. Still grinding along -- albeit
    with low volume usage.
