Question about HP LaserJet 2840 Printer

2 Answers

Restart needed, calibrations

Every so often the machine gets stubborn and simply doesn't do anything when I push the 'copy' button. I have to turn the machine off and on again, then it goes through this whole 'calibrating...' routine and then it works again. Any ideas?

Do a manual calibration from printer display (yes, on printer)
3-4times without pause between. That should solve it! It means something is out of sync. Worked for me.

Hey there. Try Up-grading the firmware (U can check if is the latest by printing a config page). Other things to do - replace the USB cable (if U're using it locally) - the USB cable must have under 1.8 m and should be shiended otherwise should have filters on each end.

Screen calibration screwed up.. need to know how to reset it?


You can get back into the touch-screen calibration routine if you start up the machine with both of the needle offset buttons pressed at the same time ... once you've calibrated the touch-screen you'll be OK again.

Bernina 165 touchscreen not working


It sounds like you may have two problems - one is easy, but without the other, its hard !!! If the touchscreen isn't working, it may simply be mis-calibrated and cant be accessed. To recalibrate the touchscreen from scratch, switch the machine on whilst, at the same time, pressing both of the two needle position buttons - the calibration screen should then come up and you should touch the screen where the dots are shown to recalibrate it. If, pressing the dots does not do anything, the probability is that your touch overlay or main control board is faulty, in which case you will need to take it to your Bernina agent. If you manage to re-calibrate the touchscreen OK, switch the machine off and back on again and if the display is still very grey but readable, you can adjust the contrast of the display by pressing the button with an arrow facing right, inside a box - this will take you to the user adjustment menu. Touch the display button that has a symbol with three vertical bars of different shades of grey and this will take you to a display that allows the brightness and contrast to be adjusted - touch the up or down buttons to get the best display contrast and once this is done, you should be all working again. Good Luck

My washing machine would stop and beep and not advance to the next wash cycle and it was taking forever to fill up. I did the diagnostics and found it to be #49 which is a faulty hot or cold water valve. ...


Sorry for the very much delayed response due to site changes which modified the notification system.

Anyway, you should try holding first the WASH TEMP DOWN button then the POWER button until there's a beep. If it doesn't work, use WASH TEMP UP instead.

Make sure the Restart feature is turned on and the Recycle feature is turned off if all else fails. During the diagnostic mode use the WATER LEVEL DOWN button to turn RESTART on by pressing the said button until the LOW WATER LEVEL LED turns on. Use the WATER LEVEL UP button to turn RECYCLE off. The MEDIUM WATER LEVEL LED off indicates RECYCLE OFF. To set these modes in EEPROM the Advance button must be held while selecting Restart or Recycle. Power off the machine thereafter to complete the reset.

I'm having a flashing light s on the push buttons for the 2 windshield and air conditioner and air flow buttons


(copied and reposted from another person)....I had the same problem you do. What has most likely happened is that the Heater-a/c unit needs to be recalibrated. Here are the steps to do it.
With the engine running and fully warmed up, A/C has to be turned off for at least 5 minutes [don't turn it on at all] and transmission in Park do the following
1. Set the temp control all the way to cold
2. Set the mode selector to Vent [blowing in your face] so air blows out of the dash panel outlets.
3. Hold down the rear washer button [top left] and the rear wiper button [bottom left] simultaineously for about 5 seconds until most all of the heater and ac panel lights blink and then release both buttons.
6. At this point the system should go into a self calibration test which can take up to 60 seconds. While it is calibrating various control panel switch lights will blink as it goes through it's tests.
7. When the system is done calibrating then just the rear wiper light should be flashing and you can exit the test by turning off the vehicle. Wait about 10 seconds and restart the engine and it should be fine. If both the rear wiper and intermittent light are both still flashing after the calibration then there is most likely a problem with the system that will need more diagnosing. This sometimes happens with battery replacement. It sometimes takes a couple of tries to calibrate so don't give up if it doesn't work the first time.

Hi Can u please tell me how to calibrate my Designer 1? Have not done it for a few years and now I've forgotten. Also my touch screen is only partially responding....I'm not getting any response...


Hi Vina, Since you can't get any response to your Menu-Norm-Prog-Rep-Set-or Help on your touch screen but you can get into your stitches, It does sound like you need to re-calibrate your touch screen. Normally you would get into your Set Menu to access your touch screen calibration. But as suggested on another solution. You turn off your Des 1, Holding in the reverse button (bottom left of the eight buttons) and the pivot button (the second one from the bottom of the four buttons) at the same time and turn on your machine. This is the Service menu that pops up (try not to touch anything on this screen, it could really mess things up if you don't know what you are doing) After this screen pops up go over to the eight buttons on the far left of your machine and touch the needle up, needle down button (top right button of the eight) the Calibration Screen will pop up on your touch screen (two plus marks labeled 1 & 2) In your sewing sitting position touch the center of the #1 mark and then the #2 mark. Once you've done that the Service Screen will pop back up. Shut off your Des 1 and restart it normally. Try getting into your different menus- Menu-Norm-Prog Etc. Hopefully that fixed your Calibration issue! ** Note: If the service menu doesn't pop up when trying to hold in these 2 buttons together and turning on your Des 1 the buttons weren't held in properly and you need to turn it off and try it again. Hopefully that helped you out!! Happy Sewing!! Kathy

My leapster does not respond when touched, what can I do to fix that?


It needs Calibrated! Very easy to do. Push and hold the "?" while turning it on. Let go of the power button but keep the "?" held down. It will bring you to a screen and on the upper right side you will see a blue "Calibrate" option so press A. Then with the pen just hit the "x"'s you will see appear. After that's done restart your leapster by pressing and holding down the power button. Leapster will turn off and then release the power button after it's off and it will automatically turn back on. Problem will be fixed!

On/off button needs replacing as it has broken off the metal stem that holds it . I need to fins out how to pull the machine apart to replace the button..thanks


usually the push/pull handles that turn older dishwasher on and off simply twist on and are threaded -- you shouldn't have to dissasemble anything... get a replacement and twist it on... "righty tighty" if I'm not mistaken

Machine will freeze up on me while embroidering.


The e-unit may need calibrating. These are older machines and not like the ones out now. They are louder than the new embroidery mechanisms and not as smooth running as the newer ones. But when properly calibrated they do okay but are not the best quality. Don't compare them to the newer machines. It may be the computer board is going out too. If that happens, there isn't a way to fix as the boards are obsolete unless you can get an old one for parts. Check with a dealer for availability. Good luck.
