Question about HP LaserJet 3320mfp All-In-One Printer

1 Answer

Scan head/carriage not parking in one spot -- keeps moving.

About once a month I was getting an error "scanner bulb failure" and I couldn't do anything with the printer or scanner. Unplugging the power cord and plugging it back in would reset it and then it would usually work fine. It would power up, move the scanner head back and forth, the scanner head would stop moving and sort of park itself at one end of the scanner. Then the "scanner bulb failure" message started happening more frequently, and the other day it did it a few times. I did my usually unplug, and plugged it back in -- no error, but the scanhead keeps moving back and forth making a lot of noise inching back and forth like it was parking itself, but it never stopped and so now I've left it unplugged. I don't know how to fix it. Any suggestions? I would also like to replace this with a good color laser mfp so if you have any suggestions on that I would appreciate them as well. Thank you!!

    Thanks Soulvisitor. I have taken it apart before to replace the glass, but it is a pain. Other comments I've seen elsewhere are that mirrors might be dusty, and a firmware upgrade might help. I decided to try the firmware update first, and before I started loading the firmware the problem stopped. I went ahead and loaded the firmware anyhow, and I am going to keep an eye on the machine over the next few weeks to see if the problem reappears. If need be I can take it apart to clean the mirrors. Any idea where the best source for a bulb might be and if it is user replaceable?

    Thanks again,

The scanner is having trouble getting its "white reference" usually due to dusty mirrors, but can also be the bulb losing brightness. These are not a easy machine to pull apart if your not used to it.

Good colour laser MFP, depends on volume of prints and remember colour dont come cheap, but dont use refill cartridges, Kyocera and Oki both have good Models

    I've found that you can remove just the slit scan glass on some models and power off/on the machine a fair few times till lens is under openning you can get out the cotton buds and give it wipe, gets it going but will usally come back at a later date, for permant fix I strip optics, clean all glass,lens and mirrors, including those under black lens cover and the white reference area. I have never needed to update firmware nor change the lamp, if you want the lamp, i'm sure you could source from HP in your country but I think that is not the issue.

    For a quick dodgy fix pull lamp to the right via slitglass and power it up with a sheet of white paper on glass. I have found this forces a white reference read to be set

    Good luck, these HP all in ones all do it.

Why doesn't it scan correctly?

Hi Anonymous,
This is really difficult to answer without seeing the problem first hand.
If you suspect a possible problem with the scan motor then you could switch off completely remove the mains plug. remove the scan glass carefully clean it (It's always worth a clean both side when you have it removed.
Now mark a tiny on the metal work where the sense carriage is parked up at, so you can move the carriage manually and return it back to the start position.
Now once you have axis to the sense carriage you can move it slowly and I mean slowly across the scan table all the way to the other side, it should be smooth running once your part way across you could take a look at the mirrors if your confident enough carefully clean them with a lint free cloth. (use, hardly any pressure on the cloth to remove any dust)
Now when you get to the point where your scanner stopped when under power, can you feel anything that would bring your mirror carriage to a halt at this point.
If it's nice and smooth then return it back to the starting mark you made earlier replace the glass and switch back on.
Once your printer has returned back to ready, try another scan
If not look for error messages and go from there.
Finally try and work through the service menu something that would checkout the action of the scan unit.
Good luck.

How do I Fix a Unable to Initialize error message 51 on a Brother MFC 820CW

Error 51 relates to print head parking position.

It is blocked and carriage cannot be seated correctly.

Try to get carriage away from parking position by pulling power lead when head has moved away from parking position then slide it out the way and use a flash light to look at parking position.

look for paper debris or similar which might block it or upset a sensor.

Communications error between Windows 8.1 computer and Artisan 835 scanner

If you are getting a 'carriage jam' error as soon as you turn on your Epson printer with no tasks in progress, then check for any piece of paper stuck in the carriage. Remove the paper carefully. If the paper tears, part of it might remain inside the paper path and damage the product.

Fix 'Carriage Jam' : Open Door, clear carriage jam,
and then press OK to continue' error message
Turn off the printer and open it to see where the paper is stuck.
Manually move the carriage toward the opposite side.
Check the paper path and remove any piece of paper or any other object that is stuck in the path.
Reconnect the power cord and turn on the printer.

I was making a color copy then, I got an error code 6c10 on the Canon Pixma MX860, tried to turn on and off several times, does not fix itself. I uninstalled the driver then re-installed the driver still...

This is a very rare error. It refers to the value cam sensor within the purge unit.
The purge unit is where the head and carriage park when not printing. i suspect some foreign item (probably paper) is jammed in the purge unit. You may have fun in getting the carriage to move out of the way . Turn the power off. See if can move the carriage to the left with no resistance. if you can great. Shine a torch into the purge unit and remove any foreign item that may be there.
If the carriage wont move then power up and when you hear the motor run kill the power immediately by pulling the plug. keeps doing this unitl the carriage unlocks. If still no joy then its best left to a professional as the purge can easily be broken and its a massive job to replace it.

Good luck.

My hp printer 6110 officejet all in one keep giving message scanner failure when i want to print something

Please make sure that the printer is connected to a wall outlet and not to a surge protector because surge protector distributes the total electric supply equally to each and every device connected to that surge protector. Printer might work and might not with a surge protector but it will always work fine with a wall outlet till the hardware of the printer and power chord, adapter are working fine.

some times scanner failure error comes if it is not getting enough power supply.So if it is connected to a surge protector then I will suggest you to disconnect it and connect it directly to a wall outlet.
Now scan or copy any document and see if something happens.

If not the do check while you press scan or copy button the scanner light is moving or not?
If scanner light is not moving then do a hard re-set.

Hard Re-Set :
- disconnect power chord from the back of the printer and then from wall outlet or surge protector.
- wait for 40 secondsand then connect the power adapter to wall outlet and then to the back of the printer. The try to scan or copy....still not working then check if the scanner bulb is glowing or not?

If scanner bulb is not glowing and if you dont hear any noise while you press scan or copy...then printer hardware has gone bad and you need to replace the printer

Printer error - see manual

Without seeing for myself this is hard to diagnose. The most common reason for this error is that something is preventing the ink carriage from travelling the full length. Open the scanner unit and check that the carriage lid is fully closed, check along the carriage path for any loose objects. Turn the printer on with the scanner part open and see if it moves across at all or if there are any unusual noises. If it does move then remove the power cable while it is across to the left and check the small white gears where the carriage normally parks for any loose parts or objects which may jam the gears. If the carriage does not move then something is preventing the parking lock from unlocking and you will need a technician to look at it.

Hope this helps, good luck.

System error L1-00

the L1-00 indicate the scanner carriage is not moving. Something is stopping it. Open the document feeder and turn the copier on while watching the scan carriage (beneath the main glass) - does it move or try to move ? does it make a noise?
If it seems to be moving freely for a bit and then stop - is it going back to its "home" position (starting point). Remove the main glass and then move the scan carriage by hand (with the copier turned off) .. does the carriage move ok? check for a loose carriage drive wire or debris or something broken. Make sure the carriage locking screw is not holding it. Then turn the copier back on and see if the carriage makes an attempt to move back to its starting point. if everything seems to be moving ok then the problem could ly with the "home position" sensor. It could also possibly be a bad drive motor.

Officejet 7310: Scanner Failure

If you get a "Scanner failure" message then the problem is the motor itself. Notice how the motor works fine when the scanner is moving slowly, like copies or faxing with the original laid on the glass. HOWEVER, the scanner failure comes up when you use the automatic document feeder on top. Why? Because the scanner assembly has to move to the other side of the printer at high speed to get into position, and it's the high speed movement that triggers the error on the printer. The motor is expensive, part number Q3450-60003. Many other models use the same motor, maybe you could find one cheap somewhere and swap the motor?

If the unit is in warranty, get Epson out to it. If not check the simple things like making sure the head lock is not on. Look to see if the scanner head starts to move at all when you power up the unit. If the head does not move at all or makes an unusual noise, chances are the unit is complaining that the head is stuck or requires too much effort to move it. Other possibilities include a communication error between scanner and main board of the SPC or SPC and your computer - indicates broken connection or bad USB cable. POssibly a fault with the mainboard of the SPC itself. Error ?Cause *Remedy Scanner error ? Lamp has burnt out. * Replace the scanner lamp. ? Power is turned on without unlocking the scanner. * Unlock the CR. ? The scanner carriage is interfering with any other part. * Remove the obstacle. * Replace the scanner carriage unit.
