Is the printer hotter than normal?
It seems to be a tad warmer, and the paper comes out bloody hot.
It's a long while since I worked there. Try different paper.
Are only putting through once?
Is it stored somewhere humid?
Only going through once. As for storage, its OK now but I did go a bit OTT buying it when it was on offer so some of it was stored in a shed for a while.
Reading this between the lines its either a) your printer is getting too hot. b) you let the paper get a bit moist.
Either way, its "you are a tard for not working this out yourself"...
