Recommended for tec guys only:Error indication that service station error, open right cover check is there any obstacles in service station movement?.. check the service station connectors, if feel every thing is fine, remove service station, found dirty? remove motors, remove service station cover, clean entire unit with water, ensure that stocked ink entire should washed out, allow service station to dry, fix it up, apply grease for moving parts, fix entire back then try....for confirmation do the service test..** cleaning service station is dirty work but it will give good mileage, while cleaning take care of sucking tubes & drop detector unit.. Best of luck..

abnormally high temperature within print head.

You have two choices to TRY to fix it:
1. put in new carts. press menu then start copy b/w then  fourtimes arrow up button (AUB) quickly one after another.

press by help of AUB and OK:
7 - (Ok) 6  - (ok) 4 (ok) then start b/w copy to initiate the carts and let the machine do some power cleaning.

leave the maintenance mode by pressing AUB 9 (ok)  and 9 again.

2. Make sure that the ph is at correct position simply by pressing on it from top (power up machine. wait til ph runs to left side. unplug from power. simpl press onto the ph). replug to power.

If you still receive the error the ph is defective due to bad generic ink and needs replacing.
