Actually 16H means the transfer belt is not working properly.  That is directly from the Minolta respresentative.  Although he tried to walk me through examining the transfer belt it still did not work.  Then when I called the authorized service companies I was discouraged that the diagnosis fee was $65.  They also guessed that a transfer belt repair would be at least $200.  This is when I figured to go for broke to clean out the machine myself.  The good news?  IT WORKED !!


Here are the step by step directions:

1.  Turn off the Minolta 2300.   Safety is always the first step.

2.  Open the panel door exposing the toner waste container and cartridge access area.

3.  Gently pry away the waste toner container from the printerr.  Be careful because it is full of toner powder that is waste and easily spills out of the two port holes  Go outside and dispose of the waste toner powder into a garbage bag.  Stand upwind incase the toner dust blows out.  KEEP THE CONTAINER!!

4.  When you return to the printer, put the waste toner container aside for assembly back into the printer later.

5.  Now to remove the two components of the printer.  There are two manual screws holding the transfer belt component securely. One is on the left upper part, one is on the right.  You may need a screw driver to get them loose.  Untighten them completely.  They will NOT come out.  They are designed to loosen, but stay attached to the transfer belt component.  That is a good thing so that you don't loose them!  Flip the large blue handle with the arrow upward.

6.  After you loosen the screws and flip the blue handle upward, look for a portuding squarish handle below the larger blue handle transfer belt component.  Look caredfully at the diagram on this little handle.  You must squeeze the level on the underside of this squarish handle to unlock it.  Once unlocked you carefully slide this part out.  It has a shiny green cylinder which you probably should not touch.  Put this whole component aside for later assembly back in.

7.  Now you are ready to pull out the transfer belt component.  You have already loosened the two screws as above, and you have removed the shiny green cylinder part as above, so not carefully slide out the larger transfer belt component about 2/3 of the way out.  At this point you should see a pale green plastic handle on the top of this part.  You can grab that handle to assist you to remove the part completely from the printer.  At the end of sliding the component outward you will need to carefully angle the part upward (the end closest to you goes higher) because there is a metal guide track at the upper most portion of the part which will prevent the part from disengagin from the track unless you angle the part upward at the very end of the slide.  Look at how the part feeds onto that track so that you can replicate that during re-assembly.

8.  Now examine the somewhat shiny plasticky belt.  Is it torn, is it damaged, etc.?  Mine was merely covered with a film of waste toner.  It looked dirty.  I took a tissue and wiped as much of the dirty toner off.  Then I took a vacuum cleaner and without touching the belt I vacuumed all I could.  Althought I didn't do the following (because I forgot to do it) I would recommend vacuuming inside the machine too before you re-assemble to parts.

9.  Now with everything out of the printer.... just put everything back... Bye.

10.  Just kidding.  For those who want the final steps:  Angle the transfer belt part upward (the end closest to you goes upward) and guide the part onto the metal guide track at the upper portion of the printer.   Slide the component in.

11.  Tighten the two hand-screws you had loosened earlier.  

12.  Slide the shiny green cynliner component back in.  Make sure to squeeze the underside of that squarish handle at the final insertion because that permits the component to seat properly and lock in place.

13.  Flip the large blue handle back into the down position as before we started this process.

14.  Vacuum the two spots where the waste toner container port holes fit into.  ( I did this because if they are clogged, the waste toner builds up on the transfer belt and makes it excessively dirty.  That is probably one of the reasons we get the 16H fatal error message.) 

14.  Put the waste toner container back into position, making sure the port holes line up where they should.

15.  Close the door. 

16. Turn on the machine. 


You may have to re-install the driver as I did because the IP address changed after I did all this. (I have the 2300DL which has network ability.)    Give me an email if this worked for you.

    This was extremely helpful. My wife printed label on the printer. Some of the labels had gotten stuck on the transfer belt. I carefully removed them. There was adhesive and paper stuck on the belt as well. I took a risk and used WD40 on a Q-tip to clean. Then used a micro fiber cloth to remove the residue from the WD40. The belt was not damaged and the printer works perfect again. Thanks for your post.

Don't be discouraged. Inky is mistaken. Error 16 is not necessarily the end. I followed these directions and found a couple labels stuck to the image transfer belt. I carefully cleaned off the sticky residue with que tips and alchohol, cleaned up the stray toner, and now the printer is printing like new. First thing I printed was these directions in case I ever have to do it again. Thanks guys!

The Error 16 means the polygon motor has an error. This is the motor that drives the polygon mirror on the laser unit. Sorry but this generally means your printer is finished. The laser unit costs more than the printer. You could try to find a similar unit (Epson C900 C1900 is exact same printer with different badge on it) on ebay and pull it apart for the laser unit. If you decide to do so, a service manual will show you haw to remove the laser unit. Hope this helps
