Another plea for help, I'm afraid.

We have a Brother L3210 laser printer which has developed a fault I can't seem to rectify. Most of the time now prints come out with a band of smudges down the left hand side:


I've gone through the troubleshoot pages and tried everything they suggest - I've cleaned the corona wires, cleaned the drums, changed the toner cartridge but nothing has made any difference. Mrs P is getting frustrated because she has a lot of printing to do - she's never liked the printer anyway - but I'm reluctant to shell out for a new one. Has anybody come across this before, and if so, what did you do about it?

Curiously, I printed off a photo on to photo paper this morning and it was absolutely fine.

All ideas considered!

Cheers,

Chris

Let me first state that even though many years ago I worked for HP I know nothing about laser printers 

BUT if photo paper works have you tried more expensive, heavier duty regular paper?

I always use bog standard bog paper on my laserjet rather than the OEM version but it might be worth a try.

Regards,

John P

Anything's worth a try. We have used the same brand of paper for years, in both 80gsm and 100 gsm form, with absolutely no issues until now. I think I have another brand stashed away somewhere - I'll see if I can find it.

Cheers,

Chris

Stray toner? Maybe try vacuuming out the innereds of the printe?

Usual disclaimers.
If there's excess toner floating about, is it possible that the toner collector is full?

Check the pinch rollers are clean?    @Yet_Another makes a good point about checking the waste toner collector if it has one?
