sharp al 1631 light copies

[copierlady]

I HAVE A SHARP AL 1631 WITH LIGHT COPIES ON THE LEAD EDGE. IF I TURN THE MACHINE OFF THE NEXT MORNING IT MAY GIVE ME ONE OR TWO GOOD COPIES THEN IT GRADUALY GETS WORSE (BY THE 5TH COPY IT IS BAD) NEW DRUM , NEW TONER , INSTALLED.... NO LUCK. I KNOW IT HAS TO BE SOMETHING SIMPLE BUT I'M TO STRESSED TO SEE IT.
ANYBODYS BRAIN WOKING BETTER THAN MINE THIS WEEK?

This would probably be better served if it was on the Sharp forum, but I'll take a stab at it. I actually have quite a few of these in the field as well.

When I've seen this, usually it's been a flaky toner cartridge. It takes the al-100td assembly, which is a dual-component toner/developer unit. It does have a TD sensor at the bottom of it.

I refill these for the school district all of the time, and after a while, they just decide to leak too much developer to be rebuilt. I just make the schools buy more new ones and I refill those after they go out.

I know you stated that it's a new drum and toner. Is the mag roller turning good? If is isn't, you may have a bad dv drive coupler. Also, is there a good latent image on the drum? If it is, transfer is probably the problem.

It sounds like it is either a dv drive problem, or a transfer problem.
