I have a Fuji – Xerox A3 printer that can staple and fold, but sometimes the paper curls up and so the printer doesn’t staple properly. I just discovered this fantastic tip from the Fuji Xerox website which has solved my problem so I thought I’d pass it on.
I was feeding all my A4 pages long edge first, so that they came out sideways. This is the default way that my printer feeds. (It is an A3 printer and so it prints A4 pages sideways.) The printer prints faster this way because the page is shorter in the direction of travel.
But I did not realise that this is printing ‘against the grain’ and is what causes the paper to curl. I started printing lengthways and it’s a great improvement, especially when it’s a bit humid.
This only applies if you are printing with a laser printer because it heats up the page. This would not be an issue for an inkjet printer. If you have an A4 printer this will probably not be an issue either because it can only print lengthways on a4 piece of paper.
