Canon, who despite their 'office equipment' image really did more to establish desktop publishing than any other company, has already stopped using Styrofoam packing, due to consumer pressure. You might be wondering why I don't cite Hewlett Packard as the prime mover in non-impact printing. HP's genius was to send any and all software developers the drivers for their first offering, the LaserJet about 12 years ago. Canon has always done it for them. But the IT public had to feel that they were dealing with an IT company.
Perception is all.
The problem is a thin film of toner on the upper delivery rollers, visible at the top where paper exits and behind door at top rear. The lower rollers continue to push the paper, after it's skidding on the upper ones. DO NOT use on any other rollers in printer or cartridge, such as foam roller under cartridge.
