BH1050 poor quality & toner rub off

Re: BH1050 poor quality & toner rub off

You'll have quite a job purging generic toner. The large volume of developer on this model holds about 3000 copies worth toner. Like allan suggests, the best course is to vacuum out the hopper and sub-hopper, installing OEM toner, and do a complete developer change. Between generic toner and a worn out pressure roller, that could account for fusing problems. I'd still be interested in seeing that sample. =^..^=

I called the customer yesterday so I could stop by and he said he would call me later.
I still haven't heard from him yet. I may just stop by without warning. I know he is
concerned about the charges.
I'll see what I can do about that sample.

Thanks

I rescanned as a gray scale and resolution at 300dpi. Still could not up load.
I will work on this later. My gut feel is that the aftermarket toner is at fault.

Here is the meter reading from the BH1050 4019452.

If he changed the upper fuser roller.. If it's anything like the 950, there is a soft fuser roller that requires different pressure springs and dipswitch settings to run. Make sure the upper fuser roller is a hard roller, if he just slapped in a soft upper roller with out doing the mods, it would cause poor fusing. Sounds like this machine is a bag of mess, I wouldn't touch it either.. But good luck.. At least it's chargeable.

Do you mean the red roller for the B1250? I know the black roller for the B050 fits the B1250, it's a lot cheaper but i would not use it there.

Compytech and allan,
Thank you for that input. I will try and get the customer to let me come back and check those rollers.
I will also check the product code.
So far I have not charged him anything.
I thought for sure that using the canon spool corona wire would be causing some of the quality problem.

Here are those samples I spoke of. The first one is #8 test print at 255 density and the next one
is #8 at 70 density. The lead edge is on the left side. It exited face down.
The streaks from the lead edge to about the center of the page can be matched to the lower fuser roller.
Its the vertical bands that I am concerned about. Those are the ones that remind me of a dev problem.

Thanks for advice on posting these samples

Just start with a basic PM. Drum, blades, developer, corona wires and grid, vibration rubbers and discharge wire. And get rid of the toner in the system.

Alan,
That was my gut feel from the start. Start over on the PM.
