HV-source from old laser-printer
I have around maybe 3 old laser-printers (using toner as ink, standard office-types), which technologically should contain som xx-kV source, which
strips of the residual toner from the ready print.
Since I occasionally have some use for a mild, non-dangerous k-voltage, I usually have a hacked small TV-set (anode-voltage ...) for it, which is
quite heavy to carry around ...
Now: How does the source of such a printer compare to the TV ? I also figure, that it might be usable with just some 9V-Battery, to give the 10+ kV
... ?? Is it a potentially mobile kV-source ? How many mA ?

It's really going to depend on the specific printer. The one I tore apart ran the HV off of a rectified line voltage feed. On the other hand, this
module sounds as if it is similar to what you want, and it may be in some printers:

however it won't run off a 9 V battery, as it looks to pull a couple of amps at 24 V.

I have occaisional need for a highly concentrated, very bright, white light. Would the same printer furnish me with such a thing?

No, they use lasers, the oldest ones used HeNe while newer ones use near IR. Some models used quartz halogen lamps for fusing the ink, most use
heaters that run a bit cooler.
A quartz halogen bulb is likely the best bet, narrow and fairly short, and a spectrum that is near blackbody @ 3200K .

I have a 1994 apple laserwriter ; might it contain a HeNe-laser ? Also some other early-90's printers, an old Fax too ...
