Color Laser Printer Printing Full Page Magenta

I have a user who prints from a HP Laserjet Pro 400 M475dn. Randomly when it prints out, the left side of the page is smeared (for lack of a better word) with pink from top to bottom. The words and everything still print out fine on the pink section....but its pink. I thought to change the toner cartridge, but this pink thing doesn't happen all the time, its random. I feel like if there was a hardware problem, this issue would be happening more consistently. The user claims that she notices it happens most when she is printing PDF files (From Adobe Standard XI) but has complained about it happening on Excel files before. She recently got a new computer, and the same problem was happening on her old computer, as well as on the new computer. This leads me back to the printer being the problem, but I don't know why it wouldn't be more consistent.
Just wondering if anyone has seen this before or had any insight on what is going on

It sounds like a leaky Magenta cartridge or left over toner from a previously leaky cartridge getting picked up in the paper path. You should try removing the Magenta cartridge and check for leaks / smears around the outside, also clean out any toner residue in the printer's cartridge slot and in any of the paper path below. It wouldn't hurt to check the other colors as well. One reason the issue is intermittent could be vibration during printing causing excess toner to fall on the paper path.

To be honest, we have leased HP printers that use the cartridges that are the toner and the drums all in one. When we sometimes get the exact same issue as you, changing out the toner for the color that is on the side will fix it. We are given aftermarket toner through our lease but I do not know if you have the same deal.

Thanks for the replys. The cartridges are those cheaper refilled ones (which I know have a reputation for having issues). I did take out the magenta cartridge and noticed there seemed to be a little excess toner on the outside, and I spotted some magenta that seemed to fall out onto the path under it (vibration mentioned could be the culprit). I cleaned up all that I could find, and put in a fresh magenta cartridge and told her to print like she normally does. Since it was an intermittent problem, I'll have to wait it out and let time be the judge. I'll update when I know more
Sounds like you may have found the issue with a toner cartridge.

@CoolHandWuch, thank you for your inquiry and thanks for the very helpful input from the IT Pros. As you state yourself cheaper refilled cartridges/toner can be problematic. Thanks for your detailed troubleshooting and we await, at your convenience your update. Please look for my ping so we can continue the discussion.
I've had this problem with genuine HP toner cartridges. Sometimes they burp. The only thing that I know you can do is replace it and blow the dust out of the unit.
IIRC I have seen this sort of thing caused by a bad or contaminated imaging drum.
1. Fuser
2. Drum Cartridge
3. bad toner
4. air can - spray inside/clean
It's feeling fabulous?!...just kidding, no idea, I hate printers.
If the cartridge thing doesn't work try replacing the drum(if it has one). Had a similar problem yesterday and that fixed it.
I have seen this on other HP printers. It is either a bad toner cartridge leaving toner, most likely the magenta in your case or imaging drum. When its the drum take it out (be ready to get some toner on your clothes) flip it over and look where the "belt" comes back into the machine for any paper in between the belt and the piece of rubber that scrapes off the excess toner. I had to tell our F&B department to look at the pre hole-punched paper before putting the paper in the paper tray. There would be the random piece of paper that didn't make it all the way out and would get stuck on the belt because of the static charge on the belt. If the imaging drum isn't that old you can take apart the end that scrapes off the toner to dump out what ever is in there to make sure that all the paper is out. You will of coarse want to do this over a good side trash can.
Wait, this isn't a feature? *grin*
It's because printers are sent from hell to make us miserable.

Let me guess, this is a black and white printer, yeah it's late.
We had the same problem on our Brother printers. It is the applicable color, in your case magenta, that is wasting toner. The cartridge itself is wasting toner and needs to be replaced.
It wastes toner onto the belt unit, then when the documents get printed, the "pink" toner wasted on the belt unit also gets fused onto the paper creating the "pink" smear you notice. Just replace the magenta toner, clean the belt unit with compressed air and surgical spirits.
Sounds like your printer may just be expressing it's sexual orientation.

There is nothing wrong with a printer that likes to show a bit of pink every once in a while...

I've had this and it was because the heating parts weren't heating up the colour enough to fully set it so it was leaving bits of toner to be picked up later on the same or other prints.
This may be the Fuser that VirtualChi mentions.
We have had this recently, we found it was residue from the toner on the roller at the back of the printer, behind the access flap, using a platen cleaner on some absorbent paper solved our issue, we now have a can on each of our sites to save us the journey to and from each printer.
Refilled toner cartridges are always bad news, especially on HP printers. The magenta cartridge is defective, and this is a perfect example of one of the many reasons to use only the genuine HP toner cartridges. The refilled cartridges fail because they are already partially worn out - the seals and wipers rarely are changed by the cartridge refillers, and the drum is only marginal at best. It's false economy to use these refilled toner cartridges, and they will eventually cause damage to your printer.

Am I the only one cringing when I read that people actually recommend compressed air to clean out toner? While this solution may work for a printer - refurbishing outfit, it should NEVER be done in an office environment.
If you can't find printer-toner-cleanup cloths, use a damp cloth that you can afford to throw away.
NEVER use an air-duster can in a printer. There are some "canned air" cans out there using very flammable HFCs and if you shake the can while spraying, the liquid is easily ignitable.
Use a good vacuum made for toner, like 3M's printer vac. It uses a special filter to trap the super fine toner particles.
