Rings true to me. Dunno when I bought the printer, but it
must've been at least 10 years ago and it's never, ever been
serviced or had the toner cartridge replaced. It's for home use
and I don't print all that much.
You don't have to do much printing to dump toner all over the printer.
Just moving it around with the toner cartridge inserted will do that.
1. How many pages are on the printer test page?
http://www.mlsd.net/helpdesk/docs/hp4000.pdf
I don't see a "Test Page" in the menu map - except for "PRINT
PAPER PATH TEST" which produces one page.
There is a "PRINT CONFIGURATION" which produces two pages: one
for the printer and one for the JetDirect card.
See the title on the above PDF page. It how to print a configuration
page. You've done that. Congrats. Now, please read the first page
and kindly disclose how many pages your printer has run.
2. Are there any stripes on the *BACK* of the page?
Yes, but very faint - maybe 5% of what's on the front.
That's enough. There's toner all over the transfer roller and
probably the red rubber roller in the fuser assembly. Cleanup time.
3. Is there toner all over the inside of the printer? Have you been
using refilled toner cartridges, which are often overfilled with
toner, and dump toner everywhere? Have you moved the printer with the
toner cart still inside? Is there loose toner on the paper that
smears off when you rub it with your finger? If you're not sure if
there's toner all over the printer, just take a piece of towel paper,
add some alcohol, and wipe the black plastic area under the fuser.
Stay away from the transfer roller. If the rag comes out black, it's
toner.
Original toner cart. Can't recall if the printer's been moved.
Original? How many pages has your printer test page show?
Gotta find out what the fuser looks like. The pics and text in
/HP_4000_FUSER.pdf arent' getting it for me. Not enough def in
the pix and the text isn't enough. This is a valuable
exercise, though. Before I guy any kit, I'll review the
instructions first to see if they're clear enough.
Those instructions are about as clear as you're going to find. I'll
see if I can find something better or with larger images, but for now,
that all there is.
I wouldn't say toner is "all over" by any means, but there is
some on one of the rollers - which, when I eyeball it, looks
suspiciously like the pattern on the pages. I *think* it's the
transfer roller.
The transfer roller is directly under the toner cartridge. Keep your
finger oils off the foam. Only handle my the metal ends.
4. Is this with a new toner cartridge? Have you tried a different
toner cartridge? Did the stripes start when you replaced the toner
cartridge?
5. Are you using MICR toner? Just curious as I've noticed that it
tends to make a bigger mess than ordinary toner.
6. Have you inspected the fuser assembly?
http://www.imagingsupplies.com/fuser-assembly-instructions/HP_4000_FUSER.pdf
7. Do you have an air compressor? If so, use it (outside the house).
I'm still recommending wholesale replacement of the rubber parts and a
general cleaning.
I'm a believer: Replace everything except maybe the fuser and
blow it all clean while doing the replacements.
Thanks for the help. You have de-mystified this issue for me.
I'm beginning to think you may be out of your depth. You're not
answering my questions, you seem reluctant to volunteer info, and the
few answers you supply are unrelated to the question. I'm trying to
save you the cost of a fuser replacement, but without info, I can only
guess. I give up. I suggest you send the printer to a professional
HP repair service shop or hire someone with experience to do the job.
