HP Calibration Error


    For HP Officejet 6600 / 6700 printer models which suffer a calibration error, more than likely either the PRINTHEAD has connectivity issues (i.e. remove, clean all contact points, and reinstall), compatible/clone ink cartridge chips are causing the issue, the PRINTHEAD is approaching end of life, or not all ink nozzles are firing and therefore the printer is unable to calibration. Perform the following diagnostic checks to help make a determination:

    Tap 41 PRINTHEAD Health Diagnostics (NOTE: applies to touchscreen 6600/6700/8600/8700 printer models only):

      1.Press 'Return' button (lower left side) four (4) times until 'Support' menu is displayed.
      2.At 'Support' Menu, using the arrow key, navigate to the 'Service Menu', press Ok.
      3.Use arrow keys to advance to the 'Special Reports' Menu. Select OK.
      4.Use arrow keys to advance to the 'print mech button tap' menu. Select Ok.
      5.'code = 0' will be displayed. Use arrows keys to change value to '41' (i.e. press and hold right arrow key).
      6.When 'Code = 41', select 'OK'. The diagnostic test pattern will print.
      7.Check the 4th line at the top of the printed report; an electrically good/stable PRINTHEAD will state "Pen Status: Pen OK".........if any other message is displayed then the PRINTHEAD may have failed and may need to be replaced. Re-seat PRINTHEAD and/or clean rear electrical contacts and repeat 'Tap 41' test to verify connectivity is not the issue.

      Nozzle test (use to determine if all ink cartridge nozzles/printhead is firing all colors properly)
      Press return arrow 4 times
      2.Press support menu
      3.Press right arrow 5 times to print diagnostic menu and press ok
      4.At nozzle test press ok


      Self test/printer status (use to print internal printer settings)
      Press return arrow 4 times
      2.Press support menu
      3.Press right hand arrow 7 times to reports menu and press ok
      4.At self test report press ok


      Extended self test (use to evaluate color performance and obtain total page count)
      Press return arrow 4 times
      2.Press support menu
      3.Press right hand arrow 7 times to reports menu and press ok
      4.Press right hand arrow 1 time to extended self-test and press ok


      Print Quality Diagnostic Page (use to determine if printing alignment is correct)
      Press return arrow 4 times
      2.Press support menu
      3.Press right hand arrow 7 times to reports menu and press ok
      4.Press right hand arrow 2 times to Print Quality diagnostic report and press ok
      Print head recovery (runs 'intensive' printhead service cleaning routines, i.e. for a clogged printhead)
        1.Press home key twice
        2.Then return key
        3.Then home key twice
        4.Then return key
        5.Then home key twice...............this will gain access to the Engineering Menu
        6.Press the 'service menu'
        7.Press right arrow 4 times to 'service test' and press ok
        8.Press right arrow:
        a.16 times to 'print head rec level 1' (basic recovery)
        b.17 times to 'print head rec level 2' (medium recovery)
        c.18 times to 'print head rec level 3' (thorough recovery)....suggested for severe streaking
        9.Press 'ok' to activate either of the 3 selections above.


        Semi full reset (can be used to help address intermittent or incorrect printer behavior issues)
          1.Press return arrow 4 times
          2.Press support menu
          3.Press right hand arrow 2 times to Resets menu and press ok
          4.Press right hand arrow 2 times to semi full reset and press ok (Note: this will return printer to factory default condition; regional setup will be required following this action)

My number pad on my keyboard is not working, how can I reactivate it?


At the top, left corner of the number pad, there should be a key that says "Num Lock." This key toggles the functionality of the number pad keys between Numbers and Directions.

Press Num Lock once and the numbers should start working again.

Press it again, and the keys should go back to the Directions (up, down, left, right, Page Up, etc.)

Good luck!

The touchpad (and buttons) stopped working. No response at all. External mouse works fine, so it is not a software issue. Could this be a loose connection? or do these fail after a while? Are the...


Is there a button with a light on it near your touch pad, sometimes these buttons don't have lights? Usually this button is centered on the bottom or top of the touch pad. If there is a button like this, then try pressing it to see if it gives you functionality of the touch pad. If you do have a button like this and it doesn't resolve the problem then there is a possibility that the touch pad has malfunctioned or that the connector has come loose somehow. If you don't have this type of button then look at your keyboard to see if there is a function key for turning off\on the touch pad. Look for the FN key. What color is it? Then look at the keys that have icons in that color. If you find one that you believe is for the keyboard then try pressing that key and the FN key at the same time.

03 POLLING
04 MEMORY REFERENCE
09 REPORT

EG. Setting unit telephone number

My Sharp Remote Control Is Suddenly Stop Working


Ok I just dealt with the Sharp customer support for this problem.

1) You need to unplug the TV for 1 full minute and remove the batteries from your remote aswell (this will reset the system)
2) Hold the power button on the remote for 30 seconds with the batteries still out of the remote and the TV still unplugged
3) After the 30 seconds replace batteries then press every button on the remote beginning with the power button in order from left to right and top to bottom (same way you read)
4) Then plug your tv back in and try the remote again.... and the remote and TV should be back in sync.
