Today I was trying to use my HP Photosmart C7280 printer and I kept getting error messages about a carriage jam, and this is the first tme I’ve ever had that error message. Paper jams I have seen aplenty, but never a carriage jam, until today,
and I’ve had this printer for about seven years of not more.
So I found this instructional troubleshooting video, and started following the steps. About midway through it tells you to lift off the cartridge cover and check for anything blocking the motion of the carriage, or simply any crumpled and ripped paper that shouldn’t be there. I found and removed some bits of paper from the carriage area, which seemed like it would probably fix the problem. Only, as I removed the paper I suddenly discovered that my fingertips were drenched in very dark blue ink, and as I washed my hands I discovered a tiny little square sponge that seemed to be the source of all this ink. It was about an inch long on each side, and somewhat less than a quarter inch thick.
So, my question is, where might this sponge have come loose from? Would it be from the carriage itself, in which case it seems the repair would be more difficult if not impossible? Or was it something that came out of the replaceable ink cartridges or from the receptacles where you plug in the cartridges when you replace them?
You’re probably wondering why I don’t just open the printer again and see for myself; that’s simply because I don’t want to drench myself, or the table or carpet, with more ink if I don’t have to, or at least not without knowing where the problem is located within the printer. If I know where that sponge fell out of in the first place, it would be helpful.
