Usually inkjet printers are dirty ones, its requires periodically service, better overhaul the printer. 85% of complaints will resolve in service level only, try it best off luck..

A carriage jam isn't necessarily caused by a paper jam. Have you tried all of these steps?

your printer is having hardware problem plz take it for servicing

after closing the cover and removing the jammed papaer does it still says "paper or carriage jam"????

if it still prompts you that theres a jam and you've already removed it, try to turn off the printer, disconnect from its connections (pc and ivr or ups or wherever its connected) wait for like 5-10 sec then connect it again...

hope this resolves ur prob...

Did you try shutting it off, unplugging it from the wall and your computer for at least 1 minute then restarting it ?

Lift the printer cover. undo the 2 screws (torx head). remove the right hand end of the printer casing.

You will see a blavck plastic moulding with a couple of gears (it controls the cartridge cleaning). This is the cause of your jam - it is out of sync. Turn the machine on and watch what happens with this moulding you will see what I mean by out of sync and it can just be gently pushed back into alignment. Once it is ok turn the unit off and then on again and your jam should be cleared. Put it back together again and print away.

Make sure to check all the way to the right and left inside. I ussually find paper loose in either of those ends. Then check your encoder strip which is the plastic strip that the carriage slides on. This may be dirty causing this issue. Use a soft paper towel and alcohol. Windex is okay to but may leave streaks on it and give same issue.
