[CTS] Re: Samsung printer

The 1100 uses a "centronics B" cable, basically a mini centronics - widely
available if you know that it isn't proprietary. even the big LJ 81xx units
use Centronics B for parallel.

I still work on laserjet II and III units - many go back 15 yrs. The 4200 is
a good unit other than the affliction with the ground spring and the fusers.
Not much different than the 4000 and for my own purchase I would get a 4000
before a 4200 mainly because of the toner chip.

  So, the bottom line is the 4200 is bound for trouble? As far as the older
HPs, we have some that have been going steady for years. By older I mean
1100, 1200, 1300, 2200 etc. The 1100s were a pain in the arse because they
took a different cable than anything else on the market. Nevertheless, I
think we still have one in use. The 1200/1300 series  have been great. So
far, nary a problem with a single one.

  The thing about HP is, if one does go down you can find someone to work on
it. Try that with a Samsung, at least around here, and its not going to
happen.

  I can see as a repairman you would have a different take on these things
than a user. The same thing applies to most anything IT. The user never has
a thought about how it works and what will go bad, and especially what to do
to minimize problems.

  At EST 05:39 PM 12/11/2005, - Russ Blakeman duly noted:

    The 4000/4100/4200 line as well as the 2100/2200 and others like the
1100 and other smaller units even back to the 5L and 6L line use a ceramic
heater (as opposed to a halogen heater bulb) with a spinning teflon film
around that (as opposed to a non-stick coated aluminum roller tube) and on
some HP had a service note to replace fusers at their cost due to the film
guides being produced with a flaw that caused the film to ram hard into one
side and eventually shred apart. Other ones from the ignorance of the
untrained users will get twisted in half at the middle as they pull stuck
paper out incorrectly - they don't use the provided green wheel or the
release levers and therefore the paper in between the pressure roller (lower
roller) and the combination heater/frame and fuser fil, that replaced the
top roller is tight and pulling causes the film to spin on one half while
stopped on the other and it twists it apart.

    I used to buy refurbished fusers, now I get rebuild kits for the fusers
at a much reduced cost.  I do this on most HP fusers now, film/ceramic and
conventional heater bulb/tube roller types.

    The 4200 and 4250 are another one with a chip, uses an antenna to
recieve/talk with the toner. If you pull the toner on the right side of the
toner at the edge that heads into the machine first you will see a copper
(brass looking) pad with a 3/8" blob of what looks like a melted plastic or
epoxy - that epoxy is covering the chip that dies when the toner goes empty
so that if refilled it still shows empty.

    One thing that does cause "remove sealing tape", "toner low" or even a
lack of an image on the 42xx machines is a spring wire that stays in the
left groove to make contact with the toner's ground that doubles as a guid
pin on the left. The design of the 4000 and 4100 for the spring wire is
different than the 4200 and consequently the 4200/4250 is prone to the wire
getting out of it's place causing ground related mis-behaviors. Your Samsung
could have a similar problem but generally Samsungs have been pretty sturdy
machines even though not generally the mainstream brand for offices. The way
Hp is going they may one day be bottom line and others like lexmark,
Brother, Samsung. Okidata, etc be the normal thing in offices.
