[comp.sys.mac.hardware] Laserwriter IINT problems

toddm@unicorn.cc.wwu.edu (todd morton) (12/28/90)

I have a Laserwriter IINT that is 2 years old and has printed 2500pgs.
Since this printer is on an Appletalk network I keep it powered up 
all the time.
The problem is this...
I had to have a fusing assembly replaced due to paper feed problems.
(Ouch...$500)
Now I am getting black smudges/streaks on my printouts. I called the
service rep. that did the previous repair and was told that I needed
a new cartridge... 
Having spent $500 on the printer already and expecting a cartridge to
last ~4000 pgs I am at a loss. I print mostly text with some mixed graphics
...nothing unusual.

I cleaned the printer as suggessed in the users manual but the problem
remains.

Question: Do toner cartridges also age with time? Requiring a replacement
after two years?

I had a similar experience with a "service rep" :-) here. I fixed the problem
by cleaning the primary corona wire in the laser cartridge. The directions for
this procedure can be found on page 10 and 11 of the EP-S cartridge
installation manual.
