Re: Power Issue HP 9500n

Hi did you have a power surge before this problem? Or did you pull the power cord out of the wall socket before the system fans had shut down? If the answer to the above is yes then unfortunately you have blown the power supply board. The only way to get the machine working again is to replace the board.

If the answer is no then as you may have blown the power board it could be simple as the power switch is faulty or open the back of the machine and check the power board it is the one with the power supply input attached. I cannot remember if there is a fuse but using a continuity tester test the fuses if any.

Thanks J

HP LJ cm2320 wont power on

Actually, if the manual says it's the fuser, it's probably the fuser. I haven't had this problem myself, but circuit boards coming before the fuser are not indicative of anything.

Again without personal experience with this specific part; I would suggest buying one locally rather than on the internet, open the packaging very carefully, and take it back to the store if it doesn't fix the problem.

My HP C3180 printer has unprinted data stored in it. How can I delete all this data without printing it ?? Thanks,

What i would suggest would be to reset your printer:

***Perform a hard reset***

Follow these steps to reset the product.
-Turn the power off.
-Unplug the power cord and the data cable from the product.
-Unplug the power cord from the wall outlet.
-Reconnect the power cord to the product and wall outlet, and then turn the power on.
-Print a self-test page again and check the print speed.
-If the test page prints in about 30 seconds, the reset has corrected the issue. If that does not resolve your problem, check the link below and follow it as per your issue.

Good luck,

My HP office 7310 all-in-one says "warming up"


Here are some solutions that can help you resolve the issue.

Check the scanner light.
-press start copy color in the control panel of the printer, make a copy of any document you have, while doing that slightly open the lid to check if the light is visible, if the scanner moves withoout a light, contact the HP support and have it serviced. If there is a light, make sure that the printer is connected directly to a power outlet not to a power strip (this is to ensure that ebough electric currect is flowint to the printer). Repeat the scanning to check if the problem persist, if it does try another power outlet. If still the same try restart the printer, after restarting, while the printer is on, remove the power cable on the back of the printer then unplug it to the power outlet wait for about 15 - 20 secs then plug the cable to the outlet and to the back of the printer, then try scannin again. if still the same then do partial reset of the printer. Remove the power cable press and hold the # and number 3 keys while doing it reconnect the power cable then try to scan again, if the issue didnt resolve anything have the printer serviced by HP.

Hope this will resolve the issue.

Thank you for choosing fixya.

I have the hpcolorlaserjet 9500n shows error code 50.6, how to solve

50.6 error is an open fuser heating circuit
between the fuser and low-voltage power supply.
Problem could be the fuser, the low voltage power supply
or the DC Controller.
The 1st thing to do is replace the fuser. If you have another one.
You should really call a printer tech to look at it.

ERROR 59.06M

This error appears after the message Conditioning Drum is displayed and then after one page is printed. Conditioning Drum occurs approx every 100 pages printed. The 59 errors can appear either after the first message was posted to the front panel or after seven messages were displayed. Power cycling the printer can clear this error in the short term.
but at the end the printer will need service, here are the parts needed to fix the issue,Process cartridge drive assembly and the Ribbon cable between DC Controller and Print Driver

HP 4250n has no power.

The first thing you should do is make sure the outlet you are plugged into is getting power. Then check the power cord -- either with a multimeter or by swapping it with a known good power cord. If the outlet and the cord are both good and you're not getting any power to the printer, the most likely option is a bad power supply unit. Maybe an electrical surge or spike fried something on the board, or maybe it just went bad over time. You can order a new one from HP or from an HP authorized reseller.

Hope that helps

Error when to turn on the Printer

This seems to be a hardware issue.
Only step which can be tried is a power flee and reset if it works it is good if not you may have to replace the printer.
First power flee.
Unplug the power cable from the All-In-One when the printer is turned On and also unplug it from the wall outlet or surg prtector leave the power cable unplugged for about 1Mins or more atleast.
Then Connect the power cable directly to wall outlet without the surg prorector first and before connecting the power cable to the All-In-One press and hold the # and No 6 button at the same tme and plug the power cord back to the printer without releasing the keys, it should come up with a message as smifull reset if it shows that message then the unit is good if not you may have to replace the unit.

Good Luck

Printer will not turn on

The all-in-one product will not turn on If the all-in-one will not turn on at all, follow the steps below in order to determine the cause:
  1. Verify that there is power at the wall outlet.
  2. Verify that the computer and the all-in-one product have a three-prong power plug.
  3. Remove the product cable from any power strips or surge suppressors, and plug it directly into a grounded (three-prong) wall outlet.
  4. For models that have an external power supply module, verify that the power supply module is plugged in correctly. Some power supply modules have a green LED built into the connector end or on the power supply module. This LED will be lit if power is present. If the LED is not lit, replace the power supply module.
  5. Plug the power cord into a different electrical outlet.
  6. If the all-in-one has an ADF with an external cable plugging into the back of the product:
    1. Turn off the unit.
    2. Unplug the power cable from the wall outlet.
    3. Unplug the ADF cable from the back of the product.
    4. Plug the ADF cable to the back of the product.
    5. Plug in the power cable to the wall outlet, and turn on the power.
      • If no change, the problem is not the ADF.
      • If the problem clears, turn off the all-in-one, unplug the power cable, and plug in the ADF.
      • If the error returns, the ADF is defective. Contact HP Customer Care to get the ADF replaced.
  7. Unplug the USB or parallel communication cable from the back of the all-in-one and try to power up the all-in-one. The computer may be grounding out through the communications cable. If this corrects the issue, check the grounding of the computer and outlet. If the above steps did not resolve your issue, contact HP for additional issue verification or the servicing of your product.
