Question about HP Photosmart C4280 Aio Printer
Greetings. We're trying to service a client's similar model. After disassembling it, we found a worn composite gear located at the ink cartrigde cleaner moving plattform (located at the front right corner of the product; it has 2 rubber cushions inside that protects the cartridge's nozzles), and a little "L" shaped plastic piece with a hooked end, located near the paper out tray (we suppose it's used in pair with a similar one for pushing the printed paper out in its tray). We substituted the gear, glued back the plastic hooked piece, and reconnect all wire harnesses, leaving clear the sides of the equipment to see it working. We observed the motor assy. located at the cartrigde cleaner unit overturning and causing the rubber cushions plattform to get stuck (therefore causing gear damage). Then, because of this failure, the cartridge carriage returned violenty to the left corner, causing breaking of the little plastic hooks (they get out during the equipment startup, but only after the cartridge carriage returns to the right corner). To isolate the problem, we removed the ribbon cable of the cleaner box motor during startup; that eliminated the violent carriage left return, but the error still flashes on the product's LCD. We have concluded the main board (PWB), Q1636-20261A, is the culprit. Can anyone agree with us, or have another view to the right solution? Thanks in advance. well......my hp c4280 all in one printer keeps showing this message that says: "carriage jam clear carriage jam . press ok.........can anybody help me? i already tried cleaning the inside and put in new ink......! _stuck_!
