Kyocera FS600 laser printer image problems

N

Nigel Jones

Hi,
I have a Kyocera FS-600 printer. It had been working well for months,
but slowly there had started to be a quite light gray background, so I
decided to clean it using a soft lint-free cotton cloth.

In the process a little toner spilled, so it too me longer.
Reassembled and print outs were good - for the first 10 or so.

Then it went downhill. I started getting even blank (ie no text
printed) sheets where there is a whole spectrum of vertical blank
lines down the page.
I have also noticed on the last test shee that the "Status Page"
banner is repeated 1/3 down the page, in a pale fashion.

Only the centre 1/3 of the print is affected apart from a splodgy 1cm
line at far right.The text, both in the dirty area and white area is
still pin sharp.

I have quickly just tried to clean without touching anything with my
fingers or pressing hard. I have very carefully used the lint-free
cloth also on the drum, in dim light taking < 2 minutes. It was quite
dirty. The reverse of the paper isn't too bad.

It seems as if perhaps the corona wire - or equiv - is dirty -- where
exactly do I go in the printer/cartridge to check this. Certainly
something is allowing toner to stay on the drum I believe. What else
do I clean? Might anything be completely broken? The transfer roller?

Thanks
Nigel
