First of all, we need to establish that there is nothing causing an obstruction, this may not be prominent on first glance. Things like hair clips, staples, pen lids and all other small objects can be dropped into the paper feed unnoticed.
Step One: Removing the power cable.
Please remove both the power and data cable before attempting any of the following solutions.Step Two: Foreign Objects.
If possible, use a flashlight or inspection lamp to illuminate the paper feed section (located at the rear of the printer where paper is inserted) and check for any foreign objects. Sometimes even having a thorough look won't uncover objects stuck further down, in this case (Do not attempt this if the printer is large and/or heavy),taking great care, you may need to turn the printer upside down and give it a little shake to dislodge the blockage.
Step Three: Only attempt if step one did not resolve the problem.
If the error occurred after a genuine paper jam, it is possible that there may be one or multiple pieces of paper still lodged in the printer, these could be in the rollers (The small cylindrical feeders that the paper passes between) and sometimes stuck underneath or either side of the printhead itself (The printhead assembly is the unit the cartridges are placed in). These pieces of paper may be covered in ink which can make them very hard to spot, arming yourself with a flashlight and a pair of tweezers should make things a lot easier for you.
After steps One and Two are completed, reconnect the power cable and turn the printer on, if this still doesn't solve the problem and you are sure there is no obstruction then move onto step Four.
Step Four: The Encoder Strip
If the paper jam error still persists, it is possible there maybe dirt, ink or grease on the encoder strip. This problem can confuse the printer and can often trigger the paper jam error, this is due to the grease/dirt blocking the laser that is shone down the encoder strip.
To clean the strip, you will need a small cloth (preferably a lint free cloth like those used to clean spectacles).
Open the lid of the printer where you find the ink cartridges and printhead, running all the way along and almost dead centre, you will find the encoder strip, a semi-transparent strip of plastic. If it looks dirty, place one hand on the left end of the strip and hold firmly (this is to prevent the strip from stretching or breaking when you clean the dirt with the other hand). Gently rub the strip horizontally up and down the entire length, taking care not to assert too much pressure.
Once this process is completed, you may reconnect the power and turn the printer on.
