HP Deskjet 1280 error

Hi good Pals, I'm working on an HP Deskjet 1280 printer the problem with it is, after initializing, it I can (in most case) print a test page from the printer but after the first print the cartridge will move to the far right corner and make some rocking noise after which the first two lights(the power and paper lights-green & amber light respectively) will start blinking in unison. I have changed the two cartridges but the problem is still there. When I try printing from the PC I have the same problem with a "cartridge jam" message. I have cleaned all the excess ink in the printer. Thanks.

Hi!

Your printer is most likely suffering from a belt that is slipping. There is a tensioning spring that holds the belt tight, and after several years, it tends to back off and allow the driving motor to skip a few teeth. This throws the mechanism just far enough out of whack for the printer's own onboard controller or the driver software to say "what?" and shut things down. The blinking lights indicate this fault.

Sometimes, you might find that the sensing stripe (the piece of plastic running along behind the carriage) is dirty. It can cause similar problems, so make sure there is not a blob of ink on it. Be GENTLE when cleaning it.

And don't forget to check for any foreign objects that may really be blocking the path of the carriage. Stuff happens...

Look inside the printer. Just above the head guide bar is a suspended strip of plastic film. If you look carefully, it has plenty of thin black lines. That's the optical encoder strip that the printer uses to locate the head position. If it gets dirty, splashed with ink, smudged with dirty fingers, or otherwise mangled, you'll have problems similar to what you describe. You can also have problems with a dirty photo emitter/detector assembly inside the head traveller. Clean the strip and it might work.
