See the illustrated instructions on the first page of the manual at http://files.sharpusa.com/Downloads/ForHome/HomeOffice/Calculators/Manuals/cal_man_EL1750PIII.pdf

Reset the unit. (check how to do this from your user manual, usually holding the start button for 5secs or pressing two button simultaneously indicated by a line and two dots on the selection panel but models vary). |If you need to repost or comment for additional advise please add the full Enr number. All the best and good luck.

Rather than trying to describe the procedure (lift this arm, slide the paper in here, etc.), I'll suggest that you follow the illustrated instructions in the manual here: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=346&modelid=15431

Feed the paper in the back press the paper advance button while pushing the paper in the rear slot, and it should feed the paper through.
Hope this helps.
Good luck.

Make sure that it is installed properly ... going under not OVER. Does the paper feed when the paper feed key is depressed ??

1. Lift the paper holder up.
2. Fold the leading edge of the paper roll 3 to 5 cm. (Do not fold it slantwise.)
3. Insert the paper roll from the left side of the paper holder and make sure the paper
roll is set in the proper direction (with the paper feeding from the bottom).
4. Insert the leading edge of the paper into the opening directly behind the print
mechanism.
5. Press the paper feed key and feed the paper under the edge of the paper cutter.
