If those items do not work, I highly suggest in it being that new you request service, replacement etc. under warranty by calling their # at the bottom of that page.

Hello, Please try this: Power off the printer, take the Color cartridge out(Magenta), take a thin and dust-free cloth or tissue and clean the hysinc mirror and the printerhead lens. The hysinc mirror and printerhead lens is in the printer not on the magenta cartridge. Reinstall the print cartridge and power on. Try again to print this will help.

The Thermal printhead is most likely burned out on one side and will need replaced. It could also be the printhead connector has worked loose and is only making partial contact. Remove the connector and reinstall. If that doesn't solve the problem then it would be cheaper to purchase another fax.

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.

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.

I must have an operation manual so Ican follow instruction and at the same time I will know what is the trouble.

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
