Scanner errors are as follows for that model:

Scanner error # 

1 = dark find
2 = LMW temp find
3 = bulb warm up from off
4 = bulb warm up from coarse
5 = cal label find
6 = doc original find
7 = LMW final find
8 = cal label find after scan
9 = cal label find prior to standby
10 = doc original find prior to standby
11 = bulb warm up from standby

I would see if there is an original on the flatbed glass (platen), or if something is obstructing the scanner view.

If the error persists, replace the scanner
assembly or the formatter pcb

Scanner errors on HP 3330, 3380 and other 33XX Printer/Scannners


baronvonnuke.jpg
1. Turn off printer and unplug power.


2. Lift up scanner lid so that you can see the scanning glass


3. Locate the screw on the top left side next to the small window of glass. (1 in picture) This glass is the section used for scanning from the automatic document feeder. Remove that screw and then the plastic that it was holding. Lift the glass out.

4. With the glass removed you can see the drive belt for the scanner. You need to rotate it until the scanner head moves to the left far enough that you can see the top of the moving part of the scanner. You will see a thin light bulb and a slot. Do not touch the lightbulb, it is fragile. You may need to pull on the assembly to move it the last bit to access the slot


5. Use a flashlight to see down into the slot, you will see a thin mirror that runs the width of the slot. If that mirror is dirty, that may be the problem and it needs to be cleaned.


6. Use a q-tip moistened with either alcohol or window cleaner to gently clean the mirror. Make sure you do not leave any lint in there.


7. Replace the glass and turn printer back on. If this is going to work it should come to ready.

How do I know if the bulb or ballast is bad? Light will briefly come on sometimes and then go out which leads me to believe its the ballast. 2007 Escalade


Regarding the headlight, usually you have to try a new bulb and see if the condition persists. If it does then replace the ballast next.

The seat heater probably has a broken filament so the heater is an open circuit. That requires a new seat-heater element.

As far as the defroster, call a glass shop (one that does automotive) and see if they have the ability to repair it. The odds are that you will need to replace the glass : (

The projector lamp has probably failed. If it had been overheating, the glass for the bulb would be weakened and then eventually when turned on the glass shatters, the pop you heard. Bulb replacement is usually a straight forward user replacement item. Ebay is often your best choice to get a bulb at a reasonable cost.

Hi,

Follow the below steps :-

  1. Turn off the power switch.
  2. Open the flat bes scanner cover.
  3. Get a lint free cloth such as a coffee filter or paper towel.
  4. Get isopropryl alcohol (greater than 90% is best).
  5. Dampen the cloth with the alcohol.
  6. Locate the smaller, rectangular glass window, on the left side of the flat bed scanner glass.
  7. Clean the glass.
  8. Don't forget to dry the glass too.
  9. Turn the machine back on.
In my experience, this will fix this kind of problem, in more than 90% of the cases.

If the problem persists, you need to get the unit repaired. This is because of some problem in the Tube, CCD problem or maybe in circuit board. It is related to the hardware that illuminates the paper and the hardware that absorbs the reflected light to take a image of the paper and store it.

[ Light Tube = one which emits light on the paper. There will be 2 separate ones for the feeder mechanism and for the flat glass one.
CCD = charge coupling device and its job is to convert the scanned image to digital form. ]

This is not a software problem, else you even the copies from glass bed would be bad. And so, you need physical intervention by some professional and repair/replacement of parts.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

HP All-in-One 3055 "Scanning Error 6" What can we do?


Hi Cherylanne, Give this a try: Scanner Error 6 Turn off then on

1. Clean Glass Scanner Bed.

  • If the glass scanner bed is too dirty or smeared with fingerprints and such, you may get this error. It will not clear itself simply by turning off and on the printer such as the message suggests. Even a build up of dust can cause this. It is triggering a reaction caused by a sensor in the scanner. If you clean it good and then power cycle it, the problem should go away. THIS PROCEDURE FIXED THE PROBLEM FOR THE AUTHOR.

2. Try the NVRAM INITZ reset procedure. REF

  • switch off the printer, then remove all cables connecting to the printer but just the power cable.
  • then press and hold the *(start/symoble) and 5 button togather and turn on the printer.
  • continue holding the button till you see "perment storage init" displayed and releas the button.
  • then at a given point of time the printer will ask you to change laguage,time,date etc.

3. Remove paper scrap or dust obstructing scanner or sensor. REF

4. Clean sensor / remove the glass and clean the bulb and mirrors. REF

  • turn off power
  • remove ADF and inspect blew out any dust
  • unclipped control panel cover and removed top platen cover 4 torx screws
  • inspected and dusted (blew out) the scanner
  • put platen cover back again and placed 5 sheets new paper over right side (where scanner is) and turned on came up happy
  • turned off reinstalled ADF (cleaned the white surface first) turned on again

5. Scanner Bulb is not getting to the alignment area.
