I have a conon ip 90 printer and find the documents printed in black font are horizontally "stripped". I have changed the cartrige twice but the problems remains, can you advise how to fix

your nozzles need cleaning. to do this click on start then printers and faxes then right click on your printer
click on printing preferences then maintainence, you will see an option to clean your nozzles, you may need to repeat the process.make sure you only use original ink as the cheaper options clog up the nozzles
