[REQUEST] Printer Creasing Paper

[Appletax]

My Brother laser printer is creasing the paper. The paper comes out with most of the tops bent over and creased.

Googling hasn't been very helpful.

The manufacturer's site says it could be the fuser rollers but I am not sure. I took a peek at them but not sure if they are bad. One site says they last 100-200,000 pages; I have printed approx. 15,000 pages.

The drum is a refurb. from LD Products and has been fine for several thousand prints.

Sent a thick piece of paper through in hopes of dislodging and debris in the system with no luck.

Looking @ getting a new Brother color laser printer to replace this monochrome one but would like to get it fixed so I can sell it or give it to someone.

Edit: here's a photo of the creased paper



Edit 2:

The problem only occurs when duplex printing (printing on both sides), which I have enabled system-wide - it even sucks the paper back in and turns it over when printing a 1-sided document.

When printing with duplex printing off, the issue does not occur, with it on the issue occurs when the paper gets sucked back in and pushed out the 2nd time.

Here's a photo of the rollers:

On some printers, the rollers used to wear smooth so they wouldn't properly grab the paper. We used to fix that by giving them a rub over with an emery board - if you can get at them, that is. May not help, but it's a cheap fix if it does.

Start a print job and let it pick up the paper and get half way thru the printer. Then open it up and check the paper path. Do this a few times at different time intervals and your probably going to find where its doing this.

A picture is worth a thousand words. The half page test @coffee mentioned helps to diagnose. You want to pull the power before it enters the fuser.

When I used to work on HP 8000 printers had a company on contract that used this real el-cheapo paper. It was like sand paper and the pickup and seperation rollers would only last a few weeks! Had a hard time convincing them to use quality paper instead. Finally did though.

Most of the time when paper gets creased I find its the pickup assembly. Otherwise the bearings going out on the fuser causes uneven feeding.

I discovered that the bottom of the paper tray had a group of papers creased in the middle that created a bulge and was pushing the other paper up in the middle.

Prints fine thus far, but only time will tell if that was the solution.

Just printed 1 page and it's creased. FML. Next step is to stop the print job mid-print to see where the issue is occurring - which is tricky to do.

Then it's a problem with the duplexer. Don't know the model but they usually have another roller or two involved to do that. Most of the commercial HP's have a separate module which is easily removable/serviceable. But low end printers usually aren't.

How much time have you spent trying to figure this out?
Maybe more cost effective to just give it best and recycle it.
Even if you do manage to "fix it" and sell it to someone, how do you know it won't do it again?
The new owner will then blame you and want you to fix it again.
Could become a millstone...
