Ricoh 3800c error sc285

[Guest]

When starting up the machine I have been getting this message. If I power of and on it goes away. Does anyone know what causes this and how can I fix it.

Thanks

Transfer belt issue. Clean the ID sensor located to the left of the transfer belt. If that fails, take the transfer belt off, clean the silver roller at the upper left, if that fails replace the belt or entire unit. My moneys on the id sensors being dirty/silver roller being crusted.

Also, drums that have reached their life or beyond can cause faint chevrons used for color registration which in turn gives you the 285. First check: Pm counters for drums/dev units. Then check for worn out charge rollers in if the drums are still within pm limits.

Cleaning the ID sensors and the upper left roller is good but the AP3800 doesn't use this roller for reflecting the id sensor beam like the newer models.

The AP3800 is old so I guess the transfer belt is wasted or maybe damaged by not correctly inserting one of it's units.

It's also necessary that the machine is technically able to reproduce an adequate image density (for the ACC patterns).

If one of the colors is to light, cause of no toner or developunit damage, the color registration don't work.
If the registration failes and the marge is to high the machine can't set its self automatically.
In SP mode You can do settings for main adjustment after that the machine is able to do the fine adjustments.
