After replacement of battery you power on fax machine and press

press # display show #1SSSW
press left arrow key one time display show TEST MODE

press # display show AMI MODE
Press 7 display show FACULTY 1-6
press 5 display show INK CHECK 1-2
press 2 and start key

press stop display show FACULTY 1-6
press 6 display show LOST INK CHECK
press start/copy key display show LOST INK CHECK [1]-[2]

press start/copy key display show LOST INK= (here you enter the last left side two digit which you remember for example 42)

Can't find a manual online. What does 5/4 mean, and how do I turn it off? Same for E. My biggest problem is that when I add up numbers with the print function on (for depositing large batches of...


The manual for the Canon P1-DHV is online at http://www.usa.canon.com/app/pdf/calculator/P1-DHV_G_USA_HWB.pdf>.
When the display shows "5/4", the calculator is doing 5/4 rounding which means: 5 or above round up, 4 or below round down. To control rounding press the "5/4" key.
When the display shows "E" the calculator could not complete a calculation. It can be because of dividing by 0, or because the total exceeded 1 trillion, or because the operator entered calculations faster than the calculator could complete them. Press the CI/C key to clear it.
I can't explain why you are not getting a total on the tape. Try the following example from the manual exactly as shown, and let me know if your tape shows the total.
  1. Clear the calculator (press [CI/C])
  2. Choose 5/4 rounding (press [5/4] until "5/4" displays)
  3. Choose add mode (press [DEC] until "A" displays)
  4. Choose cost-sell-margin mode (press [B-T] until "B" displays)
  5. Turn printer on (press [PRINT] until "PRINT" displays)
  6. To calculate: $12.55 + $15.75 - $5.30
  7. Key in: 1255 [+] 1575 [-] 530 [=]
  8. Tape shows: [0. C] ... [12.55 +] ... [15.75 -] ... [5.30 =] ... [23.00 *]

Texas Instrument TI-83 Plus error message ERR:MEMORY and the number keys won't work


Hit the "2nd" button in the upper left hand corner of the keypad, and then the "+" button (lower right hand corner). Then either click the down arrow once and then "enter" or just hit the "2" button. (the selection should say "2: Mem Mgmt/Del...") Hit Enter again (selecting the "1: All..." selection) Scroll through the programs on her calculator and either hit the "Del" button (upper right hand corner of the keypad) to delete the programs/variables, or hit "ENTER" to archive them. The archived programs have an asterisk, " * ", in front of them. (Note: Once you delete the programs, you CAN NOT get them back) If you have variables on there "L1" "A" etc. you can delete them and use them again later, obviously.

You can bypass this whole thing and just do "2nd" "+" "7". This combination will reset the calculator and delete any programs that are unimportant to the calculator. You will be left with the "Finance..." option in the APPS menu only...nothing else. You should be able to clear up the problem either way.

Will not print anything. Full cartridge.


Remove the cartridge and clean your contacts with isoprophyl alcohol. A cue tip may work best for this. Allow to dry. Make certain the cartridge is secured properly and the locking latch is down.

How do I use the Cost/Sell/Margin function on my Canon P100-DH 2 desktop printing calculator? Please for the love of god help me.


Cost/Sell / Margin can be very confusing it uses the following Account formulas (For Cost = Selling price - ( Selling price / Markup) For Sell = Selling Price =Cost / (1-Margin%))

It is not a pure percentage. Please respond back if you have any other questions.
