hi guys, I state that I follow ricoh, and I do not know the toshiba, but we have a couple around, today I received a ticket on 2050 that had faded colors, I went to the customer, I extracted all the development group and the pcu, put on the floor , I cleaned with a rag the led matrix of each pcu, I reassembled everything and done the calibration (even the administrator) the 2050 now prints all the colors out of register (!), if it were a ricoh would seem when you replace the laser without enter the parameters and without even doing the large calibration ... someone knows what it might be, something seems to have happened on an electronic level ... I also tried to replace all the pcu and dev with other newer, except the black because not I had, and does the same problem, the 2050 has bk = 85153, cl = 9214 ...... thanks in advance
