Image density error 12

It won't print because this error keeps occurring. I understand an error 12 could mean many things and had a printer repair person come out twice and he couldn't figure it out. I could use some enlightenment please!

    HI and thanks for replying again. I took all of those steps and it still is giving me an image density error 12. I had a Xerox repairman come out (they bought Tektronics as you probably know) and he couldn't fix it. Any more ideas?

  • judems Aug 28, 2007

    I have taken these steps to fix my image density error 12, but I still have the error and my printer won't print:
    Turn the printer power off, then on.
    Replace Imaging Unit. Turn the printer off, then on.
    If problem persists, check www2.tek.com/merlin/tko and/or contact Customer Support

    Can I do anything else other than throwing it out?
    Can I sell it for parts?

  • judems Aug 30, 2007

    Dyllan,

    I so appreciate your email. I thought maybe I could sell the toners on eBay, but never thought of the whole printer for parts. Thanks, that's what I'll do!

  • judems Aug 30, 2007

    Hi again,

    So what do you think would be a fair price to ask on eBay?

    The Consumable Life Remaining is:
    Fuser Cartridge Roll: 73%
    Imaging Unit 66%
    Black toner cartridge 52%
    Yellow toner cartridge 99%
    Magenta toner cartridge 79%
    Cyan toner cartridge 99%

I really don't think there's much else you can do at this point. I can find nothing about this error, and if Xerox has already sent a tech out twice, I think this has become a money pit for you. However, you should be able to sell it for parts. You have the 780 Plus, right? That comes with the extra 128megs of memory, which sells well on eBay. Or, you could just sell the whole non-working unit on eBay for parts. There are quite a few people who buy up non working printers and tear them apart to use in their repair shops, or take parts from two different printers to make one working one to resell. Sorry I can't give you better news. I scoured the net and only found information you've already looked at.

    Well, new the toner cartridges seem to be selling, shipped, for around $20 each. The imaging unit is closer to $200. The Fuser cartridge roller is going for about $20 shipped as well.

    If it was all new, including shipping, you could probably get $300 for it. My suggestion would be to sell the non working printer, along with all the supplies - and list the supplies in detail as you did above, for a starting bid of $150 - $200. It's possible someone will buy it to repair, and that should make your price go up substantially. Otherwise, it would still be a bargain just for the supplies.

My CLP-300 has started printing black very much lighter in density on the lower left side of documents. I tried, as best as I could understand, cleaning it. Of course I first replaced the black...


Did you try to clean the developer blades in the imaging unit?
The problem can be fixed by either replacing the imaging unit for $100+ or you can fix it yourself by cleaning the imaging unit. You will need simple hand tools and if you are careful restore the print quality of your printer. I have a link to instructions that should help you http://www.fixya.com/support/r4120906-clean_developer_blades_samsung_clp_300 Hope this helps you.

WHAT IS DENSITY SENSOR IN LASERJET 8500


The Density Sensor is located inside the right upper door and senses the colour calibration pattern for each colour formed on the transfer drum during a calibration cycle. Press GO. Print a configuration page and then troubleshoot as an Image-quality problem as instructed in the user manual. Check the transfer guide for cracks and replace if necessary. Check the event log for errors numbered 54.00.0<X> the X indicates, 5-sensor abnormality, 4-Cyan, 3-Magenta, 2-Yellow, 1-Black. The last 3 error codes should be seen on the Configuration page.

I have a Lexmark C510 and it's giving me an engine error 994. What do i do? I need your help.


here is an excerpt from the lexmark technical tips library it could be usefull


Bulletin Summary: 994 Density Sensor Error
Document Date: Feb 03 2004
Operating System: Printer Based

Issue:
The 994 Density Sensor Error can be caused my many different things. The basis of the Error comes from the printer not being able to do the auto calibration and the auto registration when the printer is turned on. Toner Patches are written to the belt on ever Power Cycle of the printer or when ever a door or cover is opened on the printer when the Auto Color Adjust is turned on and the Auto Registration is turned on. If too much of one color is placed on the belt or there is an absence of a color or all colors the printer will call the 994 Error. This error will also be called if the activation arm for the density sensor is not pushed in. Another thing that can cause the 994 Error is if the sensor for the under the belt for the BUD Clutch positioning is the incorrect part.
Solution:
Things to Try with Customer

When the printer is powered on in Diagnostics the printer does not perform the Auto Calibration of Registration functions as would normally occur on POR. Turn the printer off and POR in Diagnostic Mode. From here print the Quality Pages under the Print Tests. These quality pages can give insight as to what is causing the 994 error.

What to Look for on the Print Quality Pages

First Look at the First Page on the Print Quality Pages. The first page tells mean things about the printer. There is a section that gives the Page Count on the printer, the Last 12 Errors, the Serial Number, Engine and Rip Code Levels. There is also a section on the first page that tells the last time the printer did the Auto Registration and Calibration. If the printer does not have 703.007 RIP on a C910 or IBM 1228 Printer this may not be displayed. Since there is only one Version of RIP on the C912 and IBM 1357's 720.013 this code will display the last time the printer was did a calibration and registration.

Second - Go through all the Quality pages are any of the color planes missing completely?
If only one color plane is missing it's possible that LED array is unplugged.

Is the top half or bottom half of one or more color planes is missing completely?
If yes then that one LED or Multiple LED's May have one Cable Unplugged.

Are all the Color pages white but the black pages printed ok?
If all the colors are missing and only black appears most likely the sensor under the Belt for the BUD Clutch position sensing is the incorrect part. This would only be the cause if that sensor was just replaced during fixing a 994 Error. Another check to do if this is the case is to look at the belt while it's in the printer. Open the Top Cover of the printer and check the right and left sides of the belt. The Belt should be raised on the right side and be equal height as the left side. The pictures below show the Belt in the Up and Down Position. If the belt is down when the printer tries to do the calibration no color will get transferred to the belt. This will cause the 994 Error. This also is why no colors would be appearing in all the planes but black is fine.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
