OK, a couple of things... Some earlier Lexmark units had code on both a RIP board (raster image
processor) and an engine board. In this case, the code would have to be reloaded into both
boards. Fortunately, this can be done even if the printer will not boot to a ready state. However, if
this has already been done sucessfuly, the problem may well not be the printer but rather something
in the data stream. To confirm this, remove any and all data cables and reboot the printer. If it comes ready and you can print all the internal pages including the network config pages, then it is likely the
problem is the data stream. One must be careful when the printer is controlled by a print server
because the end user may not have control over the print que. If a corrupt or printer incomprehensible
job is stuck in the que, the printer will go to a 900 condition as soon as the network interface
initializes. This will continue until the print que is cleared.
Hope this helps...

You are correct, Below is that section from the manual. Before you follow this, i've found in the past that the cable connector is not seated properly on the rip board, so check this first.
If you require any of the instructions on replacing the printhead or board let me know.
Yellow Printhead Lost Hsync
Check for the correct installation of the all the cables to the RIP
Board assembly and to the Printhead assembly; J2, J3, and J4 on
the RIP Board. Go to “RIP Board” on page 5-11. If the cables are
connected correctly to the RIP Board and to the Printhead
assembly, replace the following FRU:
“RIP Board” on page 4-11
If this does not fix the problem replace:
Yellow Printhead Assembly - Go to “Printheads” on page 4-33.
Note: Whenever a printhead assembly is replaced, it is necessary
to perform the “Printhead Adjustments” on page 4-1.

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:
106 & 110 CYAN 107 & 111 MAGENTA 108 & 112 YELLOW 109 & 113 BLACK
