Yellow Toner Everywhere!
Long time since I've posted here. Anyway, I just picked up an HP Color LaserJet Pro 400 (M475dw) for $10. It works great, however, the yellow toner appears to have spilled inside the unit. All prints come out with yellow banding, and there are even traces of yellow inside of the magenta toners.
How do I clean the transfer rollers and related imaging equipment to restore this wonderful printer (and it's full toner cartridges) to life?
I have pictures I can upload, if needed.
I can see why it was $10. I once picked up a brand new Color Laser in the box for $30. It got returned because the dummy didn't have the patience to let it warm up all the way.
In your case, a vacuum and air compressor to clean out all the toner. Remove everything you can from inside first and do it outside or you might get yelled at. Wipe all the toner cartridges with a dry paper towel.
Thanks for your response! I've read online that isopropyl alcohol and lint-free cloths or sponges can be good for cleaning up stray toner. I'm going to try to tackle this project over the weekend.
This forum has helped me save many printers over the years; hopefully I'll be able to add this one to the list!
Do not use isopropyl on any rubber, transfer roller or on the belt.
