Overflow won't clear

I am unable to clear the "E" from the calculator in order to use the printer. Can not change the TAX or DATE now either because of this overflow error. The calculator will work in the "ON" position, but I am unable to print or change tax or date. Thank you >

Look for the reset button, then remove the batteries - this should fix it.

Hit the reset button (usually on the bottom of the calculator) and unplug or remove your batteries. After you plug it back in/return the batteries, hit the time/date key then the time set key. Enter the correct date using 0 for single digit months. ex. 02/02/2007. Set your time the same way but, hit the am/pm key for appropriate time.

This is for those running on batteries only, NOT if you are using the AC adapter. Canons are very picky about good batteries, but the "low batt" indicator seldom comes on to warn you. Try a fresh set of alkaline batteries. Lithium is OK too, but that is expensive overkill. Ordinary "heavy duty" is not good enough. The new batteries have always cleared the "E" and restarted the printer on my P23-DH.

Need to clear old tax rate and set new tax rate.


  1. To change the tax rate, first press AC.
  2. Then press SET % for 2 seconds.
  3. Next, press TAX+, then enter the new or current tax rate.
  4. Enter the rate for a single digit tax rate such as 5% as 5, a single number; if you have a fractional percentage rate, such as 5.75%, enter it just that way: the 5, then a decimal and followed by 7& 5.
  5. Then press SET % and you're done!

2. Open the printer compartment cover by pressing down on its front edge and sliding it back in the
direction of the arrow.
3. Fit the roll of paper on the holder so that it unrolls from the bottom, with the loose end toward the
calculator.
4. Cut the end of the paper squarely and insert it firmly into the printer slot on the back of the
calculator.
5. Press & until the paper is in the printing position.
Replacing the ink roller (see illustrations 5 and 6 on page ii)
