Follow this steps to resolve this problem:

3. Press 2 to select the RESET, the second item in the RESET menu. The display shows the message Mem cleared. Press CLEAR to clear the screen

If you cannot see anything on the screen, you may need to adjust the graphing TI- 81 calculator contrast:

2 ways to clear this (most likely someone tried to intercom you and pressed the message button on accident instead of hanging up):

way #1:
1) press the "MESSAGE" button
2) on the screen it will display who turned on your message light
3) press the "CLEAR" button (third button from the left directly under the screen)

way #2:
1) press "INTERCOM"
2) dial " *700 " then your extension number (you will hear a confirmation tone)
3) hang up

The ink system failure message has a chance to be fixed or it may be a permanent issue. It
can be pointing toward a firmware failure in the printer and if that is the case the
following steps should fix it.
Press and hold the “*” key. Press the “#” key and release both keys.
Display should say “Enter Special Key Combo”
Press and release in sequence the "1”, “2” and “3” buttons.
Display should say “Support” and display the FW rev (something like R0631R)
Mine reads R0631M
. Press and release the right arrow button until the display says “System Configuration
Menu”.
Press and release the “OK” button.
Display should say “Hardware failure status”. If not there already, Arrow Key over to
“Hardware failure status”,
Press and release the “OK” button.
Display should say “Hardware failure status: Clear. Press OK to clear”.
Press and release the “OK” Button. Message changes to “Hardware failure status Cleared.
Press Cancel to continue”.
Press and release the “CANCEL” button as many times as necessary, so that, either the
“Welcome to Photosmart Express” screen appears, or, the “Ink System Failure” screen appears.
PLEASE DO NOT TRY TO PRINT AT THIS STAGE.
Using the Power Button, turn the unit OFF and unplug the power cable from back of the
printer and wall outlet.
Wait 30 seconds for the power to get discharged and then plug the power cable into the wall
outlet first and then into the back of the printer.
Turn the unit on. The printer may display message “USE POWER BUTTON TO SHUTDOWN THE PRINTER”
followed by “PRESS OK TO CONTINUE”. Press OK. The Printer will start the “ONE TIME INK
INITIALIZATION PROCESS”. Allow this process to complete and do not interrupt. Once the
initialization process is complete, the printer will print out a Diagnostic Page.

Good Luck!

If there is no message and you just want to clear the light, press the message button on the bottom panel of the phone and then the button at the top under the display screen that lines up with "clear". That will turn off the message light.

PF means power failure.
For short outages the clock may still have correct time
(there is a battery backup for that), but the PF will
be displayed. Setting the clock will clear the PF
indication.

Press 'clock set-start' button, (under clock display)
enter time with numeric keypad,
press 'start' button. (to right of clock)

Use the left arrow on the direction circle then when the display shows incoming call log press the enter key. If you want to remove all entries just keep pressing the CLEAR button just below the display screen untill it goes back and show RING inplace of CLEAR.

This if you do not have the buttons below the display screen you need to get a 24 button Panasonic KX-T7630AL Corded Phone and you will have the functionality to do it, the 12 button version can not delete the logs.

ok if memmory serves me correct
press the pause clear button with start button at same time
holding them for 5 seconds the micro should beep then press1 3 5 7 for the reset micro screen its been a while since i serviced a micro but i believe this is correct display reset config for micro

Right-click an empty area of the Windows Desktop (your main screen). Click Properties, then the Settings tab. Under the slider labeled Screen area or Desktop size, slide the slider and click apply until you find the size that takes the fuzziness out of your laptop display.

Hope This helps!
