Epson Aculaser C1900
Hi, i've been having a problem with an epson aculaser c1900, it keeps asking for black toner even though it is a new one, i have tried swapping the toner with the yellow one but still get the same message, and sometimes randomly get e023, witch means carosel missalignment, but the clutch, motor, and sensor have all tested fine. while i had the machine appart i noticed the HVT was covered in yellow toner as was most of the machine inside, i've cleaned it up but still get the same problem, do you think it's the HVT or the Engine Board????
