Why won't the printer grab the heavier paper?
I just ran into this problem this morning. My printer used to be able to grab paper of all different thicknesses and run them through. However, now it will only grab very thin paper.
When I send something to the printer, I can hear the rollers spin and the paper wiggles just a tiny bit (indicating, to me, that there is some contact between the rollers and the paper). There are even "tread marks" on the paper, so that indicates to me that the rollers are trying to grab the paper. But, it just can't seem to "lift" the heavier paper. What I tried was pushing the heavier piece of paper at the start of the print cycle, then the printer was able to grab paper and run it through.
For now, I guess I'll just run cheap, thin paper through the printer. But, I'd like to figure out if there's a way to fix this before I decide to get a new printer.
