Broke something in fixing a paper jam.
With the OfficeJet 8740, I was printing business cards on microperferated card stock. The machine gobbled several of them at a time, and in repairing the paper jam (difficult because the pages pulled apart along the perfs), I think I broke something inside the back door of the printer. If there is any possible way to fix this myself, I would be happy to try; but I would also be happy to pay someone to come and fix it. If absolutely necessary, I can take it somewhere, but this is a very big machine for a desktop printer, and no so easy to transport.
