Hi I have got a Minolta CF2001 and each time I start up it says to Phone my teck and give him the code COF37 Do you know what this is leading to. Cheers Craig
COF37 is a code for ATDC high black density failure. Several different things can cause this code & I assume it does not clear by turning the machine on & off.It may be a dirty sensor or may need a black developer change. Either way I would recommend contacting a tech as the process unit can be tricky to remove.
