There is a difference in the quality of copy papers from different companies. I know this, I learned from the experience of being the bunny who always had to remove the jammed — and quite often mauled and mangled — poor quality paper from various laser printers and photocopiers over the years.
This doesn’t explain why, on needing to purchase more paper recently, my brain turned off and suddenly decided that the unknown element of ‘Artrite Office’ copy paper would be a good idea. Needless to say I regretted the decision and have since had the offending section of my brain surgically removed. Continual jams caused by an origami quirk that produced lovely concertina folds, but no actual prints.
I’m back with my regular Reflex paper and happily in the land of print once more.
