My new Dell V305w printer worked ok for a few weeks, but is now unable to feed paper correctly. It spins and seems to have trouble pulling the paper down. Sometimes the paper goes down a few inches and the printer starts to print, but the paper is not far enough into the machine to be printed. The printer continues happily printing with no paper and then finishes printing but nothing comes out. Sometimes it says there is a paper jam. I pull out the partially inserted sheet of paper and try again. And again. And again. There is nothing obstructing the wheels that I can see. I am using regular printer paper. I have the same problem with envelopes. It seems like the envelope starts to feed and then stops, like the wheel does not catch it. Sometimes the envelope will go all the way through the printer, but the printing will be trailing off the leading edge of the envelope. It seems like the wheels are not pulling the envelope or sheet of paper through the machine.
