Error Code(s) Printhead Color 

106, 111, 115, 171, 172 Cyan 
107, 112, 116, 173, 174 Magenta 
108, 113, 117, 175, 176 Yellow 
109, 110, 114, 169, 170 Black 

Power off the printer, take the Magenta cartridge out, take a lint and dust-free cloth or tissue and clean the hysinc mirror and the printerhead lens. I just did it and it took me three minutes to clean with toilet paper rolled up like a cigarette. 
My printer is back on line. The hysinc mirror and printerhead lens is in the printer not on the magenta cartridge. Reinstall the print cartridge and power on. This has happened to me before with a different color.

93x Printhead Error
Each printhead error has its own error code number. The error codes and their respective meanings are listed below, together with some actions you can take to resolve the problem. 


ALL printhead errors:
If this is the first time the error has occurred, try turning the printer off and on. 
Let it sit turned off for at least 20 seconds before powering it back on. 
If powering off and on the printer clears the error, please continue using the printer but watch it to see if any printhead errors return. 
If your printer continues to display a Printhead Error message, make sure it is plugged straight to the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer. This can trigger a printhead error even if the printer has worked on this surge device for months. 
  
If the printer continues to post a 930 Printhead Error, it thinks the wrong printhead unit is installed. 
  
If the printer was recently serviced, make sure the correct parts were used. This is especially true if the parts replaced were either the printhead unit or the printer's engine/system board. It is in one of these two parts that the printer is detecting the problem. Note: If you are the person repairing such a printer, please be aware that parts from different, though similar, printer models may not be compatible with this printer. Also make sure to check the laser cable going from the printer's engine board to the printhead unit, as it reads that signal. 
If the printer was not recently serviced before this error occurred and powering the printer off and on does not help, the printhead unit and possibly the laser cable or the engine/system board to this printer may need to be replaced. 
 
If the printer continues to post a 931 Printhead Error, it thinks there is an error in the signal going to the laser or the Hsync part of the printhead assembly. 
If the printer continues to post a 932 Printhead Error, it thinks there is an Hsync error occurring in the printhead assembly. 
If the printer continues to post a 933 Printhead Error, it thinks there is a failure in either the Hsync signal or with the mirror motor unit of the printhead.  
If the printer continues to post a 934 Printhead Error, it thinks there is a "lock" failure with the mirror motor assembly within the printhead assembly. 
If the printer continues to post a 935 Printhead Error, it thinks the mirror motor unit within the printhead unit cannot reach its operating speed.
 
If powering the printer off and on does not clear any of these errors and it is already connected directly to the wall, your printer may require service. It could have a defective printhead unit or there might be a problem with the engine board or one of the printhead cables. Note: If you are the person repairing such a printer, check all of the cables going from the printer's engine board to the printhead unit for any damage. Also check the continuity across these cables.

They mean the respective printheads have lost the HSynch.  The first thing the we do (and have had great success with) is to clean the laser lenses.  Then check the head wiring.  The following codes apply:
