mx3501n not fusing 28lb paper

[cap0319]

Trays are rated to 28lb, Would rather not use heavy setting through bypass tray.

swapped fuser out of another machine - same result.

Is the bypass the only way to go?

Also changed drums and transfer roller...

The lb listed on the paper may not always accurately reflect the weight of the paper. The stock might be 28lb bond but the individual paper weight could be higher.

At any rate if you're going through the upper spectrum of paper weight, why have the big aversion to using the bypass tray? It's designed specifically for this purpose. Your smudging is indicating that it's not getting the proper treatment it deserves, and the heavy paper setting does modify fuser behaviour to accommodate the increased paper weight.

I've just been informed there are some bit switches that can be flipped to make the fuser run just a bit hotter to fix up your fusing issue.

Sim 55-01 Switch 2 bit 1. Should end up as 1000000

All standard trays will still operate as plain paper but the fuser will operate at heavy paper temperatures. Should fix your fusing problem.

Thanks Akitu!

Such an awesome response!

The customer has the aversion because of the volume they must do of this type of paper.

It's just the usual situation, the customer wants to get the most out of the machine they have instead of buying the machine they need.

Thanks again so much!

Hotter fuser temp worked for about 800 prints. installed new fuser, no smearing anymore but now we have scratched lines through the prints, see the attached example.
Could this be from the new fuser running at the hotter temperature?

Re: mx3501n not fusing 28lb paper

Those lines look like improperly fused toner. When you installed your new fuser, did you remember to lock in the pressure tabs? If left up, they'll do exactly this, even with the increased fuser temps.

Re: mx3501n not fusing 28lb paper

Take a look at the guides on the door and the area after the fuser. Look for toner buildup on the guides. It isn't always real apparent on the guides. But based on the amount of toner coverage I would hazard a guess as that is the issue. Clean the guides and ribs with a scotch brite pad etc.

Re: mx3501n not fusing 28lb paper

Thanks for the replies gentleman, and I apologize I wasn't clear enough. The examples shown are on "Specialty Border Paper" from Paperdirect. I'm not sure if that's considered pre-printed?

The first page is a printed page and the second page was a blank copy, so we're going to check those guides and we'll let you know!

THANKS!

Re: mx3501n not fusing 28lb paper

Guides were checked, all fine, Fuser is installed properly with the pressure tabs down.

Smearing of the toner is back even with the temp change and the white lines only seem to appear on that special type of paper. other 28lb paper has no white lines but toner keeps smearing on some of the prints.

At this point were kind of running out of ideas, can we blame the paper or is there a setting were missing?

I would chalk it up to a paper issue, try running the recommended heavy paper setting through the bypass tray and see if it will continue. There's only so much we can do with the machines of course to run within specs or to modify operations in an attempt to make it work to their request.
