Paper jams each time I try to print. - HP Deskjet F340 All-In-One Printer

SOURCE: paper jams/ printing blank

Thoroughly check for very small foreign objects in your printer, and check both behind in paper feeder area and inside the unit. Jams can be tiny pieces of paper than have gotten in or torn off paper fed in at slight angle but you may not have noticed. Service you printheads and rollers both manually with solution and cotton buds (q tips) and then see if your ink may be low or out, blocked printheads will obstruct ink from flowing at all. So will damaged printhead points on cartridge, signalling replacement time.

3. open the rear access door of the printer (with grids) on the back and reval the rollers. Take a slight moist cloth ( not cotton ) and clean the rollers with it by moving them 4 times upwards.
4.open the cartridge door ad observe the thin plastic strio on top of the steel rod on which the carriage moves. Take a small piece of paper and hold the strip with it ands swipe it once witout applying much pressure as it could come out in any direction and as much as you can
5. make sure you replace the cartridge if its refilled. It could provide obstruction.
move the carriage 4-5 times continuously with as much speed and make sure there is no obstruction in the carriage movement.
6. press set up button on the printer panel - go to print reports - ok / enter - self test report - see if the paper jams. If not good.. If yes take a look into the next step.
7. pull out the power cable directly from the printer. Press and hold # and 6 button on the printer and insert the power cable and do not release the buttons till you see te display glowing blank or some processing happening. Release the #6. If the printer turns off then press on the power button to turn it on. Continue with country and language settins as apprpriate. Choose your country during this reset. Complete the alignmet then. Take a printout to see if the paper jams again.If yes - the printer definitely needs servicing.
